Summer is coming, know your sunscreen's ingredients.

Summer is coming, know your sunscreen's ingredients.

(Dr Ghohestani Interview with San Antonio Express News)




Knowing the ingredients in sunscreens and how they work will help you choose the best sunscreen product for your skin.
Sunscreens work in two different ways:

Physical Blockers. Some sunscreens (often called sunblocks) have ingredients that form a physical barrier that blocks, scatters or reflects all types of UV rays. Two common ingredients are:

• Zinc oxide is most often found in white or colored ointments that can be seen on the skin. Microfine zinc oxide (Z-cote) is a transparent zinc oxide used in sunblocks. Both types of zinc oxide protect against both UVA and UVB.
• Titanium dioxide is often included in sunscreens with other ingredients. It is less visible  than zinc oxide but still may show as a white film on children with darker skin. It protects against both UVA and UVB.
Chemical Sunscreens. Other sunscreen ingredients work by absorbing UV rays. Most of these ingredients absorb UVB rays. A few of the newer ones absorb only UVA rays. They are:
• Avobenzone (also called Parsol 1789) is not visible on the skin.
• Oxybenzone is not visible on the skin.
PABA is a sunscreen ingredient that is rarely used now, because it caused skin reactions in some people.
Choose the Best sunblock for sun protection.
There are many kinds of sunscreen. When properly applied, these sunscreens offer protection from the damaging effects of UV rays. Pick the formula that best meets your needs:
• Creams & lotions go on thick and stay on better, but they can be messy.
• Gels are somewhat harder to see, so it's easier to miss an area. Also, alcohol-based gels are more likely to irritate young children's skin.
• Sunscreen sticks are less likely to run into children's eyes. They work well for children's ears, forehead, nose and cheeks.
• Sprays take less time to apply and can save you from having greasy hands, but it can be hard to apply it evenly to all areas. Be careful to avoid spraying children's eyes.
• Towelettes are easy to throw in a bag or take on an outing. You'll want to pack at least one per child.
Waterproof or sweat-resistantsunscreens provide some additional protection for active outings but will still rub off. Remember that waterproof sunscreens need to be reapplied at least every 2 hours, especially if the children are playing in or with water or are using towels to dry off.
Colored sunscreens can be fun for kids, and can help you see where you've missed. Be aware, though, that they can stain clothing. There have also been reports that some children may react to the dyes in these products.
Sunscreens with bug repellent must meet the SPF rating on the container. However, if a product containing DEET bug repellent is reapplied every 2 hours, a child may get too much DEET. Look for a sunscreen with insect repellent that does not contain DEET.
If you need both sunscreen and a DEET-based bug repellent, apply the sunscreen first. Then apply bug repellent 15-30 minutes later, after the sunscreen has soaked into the skin.



Skin, Sun and Sun Block

Dr. Ghohestani's interview with San Antonio Express News (Updated by TID)



No SPF? UVA and UVB will leave you RED Dr. R. Fredrick Ghohestani, of the Division of Dermatology and Cutaneous Surgery at UTHSC,recommends that people wear at least SPF 30 every time they step outdoors.

If there is one thing the chief of the Division of Dermatology and Cutaneous Surgery at the University of Texas Health Science Center wants people to know about the sun, he emphasizes that sun protection needs to start at an early age.

THE ABCs OF SKIN CANCER

A is for ASYMMETRY: One half of a mole or birthmark does not match the other.

B is for BORDER: The edges are irregular, ragged, notched or blurred.

C is for COLOR: The color is not the same all over and may include shades of brown or black,sometimes with patches of red, white or blue.

D is for DIAMETER: The spot is larger than 6 millimeters across (about the size of a pencil eraser) or is growing larger.

E is for EVOLVING: The mole or birthmark is changing in any way.

Dr. Ghohestani said recent studies show that people who were sunburned as children are three to five times more likely to get skin cancer as an adult.
It's very, very important to emphasize sun protection for kids, Dr. Ghohestani said. Most people think that's not a big deal and then they end up having cancer 20-50 years later.

According to the National Cancer Institute, skin cancer is the most common form of cancer in the U.S. Every year, more than 1 million Americans are diagnosed with skin cancer.

Ultraviolet rays cause cancer by damaging the cell's center, which controls the proliferation of cells. These rays are subdivided into three categories according to their wavelength: UVA, UVB and UVC. Research and studies show that UVB rays directly cause these mutations in the DNA.
Ghohestani said that to avoid these harmful changes, it is important for people to protect their skin from the sun.

Ghohestani said he encourages people to use sunscreens that block both UVA and UVB rays every day.

We know recently that UVA is damaging to skin and chronic exposure is harmful to the skin as well, he said. We see sun-damaged skin on the left side of drivers from the windows in their car windows only block out UVB rays, not UVA rays. He said people who do not put on sunscreen every day, especially those who spend a lot of time driving, tend to have more wrinkles on the left side of their face because of sun damage.

Ghohestani recommends that people wear at least SPF 30 every time they leave their home, even on cloudy days and road trips. An adult should apply about two tablespoons of sunscreen at least 30 minutes before going out. Sunscreen should be reapplied every two hours.

He explained that without sun protection, a fair-skinned person turns red after about 10 minutes in the sun. If that same individual uses sunscreen with an SPF of 30, it will take approximately 150 minutes for his or her skin to turn red. In general, he said it is not necessary to apply sunscreen with an SPF higher than 50. However, people should consider waterproof sun protection when they are swimming because UV rays can still be harmful through one or two feet of water.

He recommends that people buy hypoallergenic sunscreen that offers protection from the sun's harmful rays. Stores typically sell a mixture of sunblock that physically blocks UV rays and sunscreen that contains chemicals, which absorb the rays.

He suggests people also protect themselves by wearing protective clothing, finding shade, and avoiding direct sun exposure from 10 a.m. to 4 p.m. during summer months. Hats and clothing with high UPF factors help decrease UV exposure. All fabrics have different UPF factors:
closely woven fabric, dark colors, and dry cloth have high UPFs.

Ghohestani urges taking precautions against sun exposure.

We really discourage people to go out and expose their skin to any ultraviolet radiation either through sun or tanning salons, he said there is a correlation between tanning and wrinkles. Instead of tanning, he recommends sunless tanning products commonly sold as creams gels, lotions and sprays. However, in the event that sunburn has already occurred due to tanning or sun exposure, he suggests waiting until it goes away or applying hydrocortisone if it is not blistered. If a burn blisters, does not disappear after a few days, or an allergic reaction occurs, seek medical attention.

Effective painless Excimer laser gives hope to San Antonio residents with Vitiligo, Alopecia, Eczema and Psoriasis

For the first time in their lives, patients who suffer from some of the defigurating skin diseases — including psoriasis, vitiligo, alopecia areata and atopic dermatitis — have real hope for effectively, and painlessly treating their skin.

Texas Institute of Dermatology, Laser and Cosmetic Surgery is the first practice in the area to offer the Alma-308 excimer laser, a gentle and painless phototherapy laser technology shown to be effective in alleviating these difficult-to-treat skin conditions. The procedure is performed at the dermatology clinic at 24165 W IH 10, #102, San Antonio, TX.

Excimer laser offers painless treatment with no recovery time for patients.

The excimer laser is different from cosmetic lasers, which are usually associated with pain during treatment and post-treatment downtime for the patient. Instead, the excimer laser delivers a highly energetic but painless beam of ultraviolet B (UVB) light directly to the psoriasis, vitiligo and atopic dermatitis patches through a hand piece that rests directly on the patient’s skin.


The excimer laser delivers more effective phototherapy treatments for patients with skin diseases, and is more convenient and painless for patients.

It features the most advanced optical technology on the market, including an adjustable spot size and guided aiming beam, to precisely target only the affected skin and spare the surrounding healthy tissue from exposure.

Alopecia Areata
Excimer laser is effective in Alopecia Areata whether its on scalp, eyebrow or face.

Psoriasis
Psoriasis is a non-contagious, lifelong autoimmune skin disease that affects an estimated 5- 7 million Americans. The most common form, plaque psoriasis, appears as raised, red patches or lesions covered with a silvery white buildup of dead skin cells called scale. In addition to discomfort and itching, psoriasis patients commonly suffer from social embarrassment and depression.

The usual treatments are messy, time-consuming and costly. At Texas Institute of Dermatology, patients come in twice each week for an average of 4-6 weeks, and each treatment session usually takes only 5-10 minutes. Patients usually enjoy several months of treatment-free remission.

“Patients really like it,” said Reza F. Ghohestani, M.D. Ph.D, Dermatologist and Laser specialist who has years of experience in treatment of autoimmune skin diseases.

Vitiligo
Vitiligo is characterized by the white patches of skin on different parts of the body as a result of the destruction of melanocytes. Vitiligo is not contagious. For some people, although not for everyone, the depigmentation is progressive. Vitiligo affects 1 to 5 percent of the world’s population, including approximately 2 million Americans.

Prior to the excimer laser, vitiligo patients’ treatment options were usually limited to topical steroids with limited efficacy and traditional phototherapy that often required hundreds of treatments and exposed all of the patients’ skin to UV light, increasing risks such as photo-aging and carcinogenicity. Now vitiligo patients at the UT Health Science Center’s dermatology clinic can benefit from the excimer laser’s proven repigmentation technology with none of the downsides of steroids or old-fashioned phototherapy.

Atopic dermatitis and eczema
The excimer laser also treats topic dermatitis, hereditary skin inflammation that commonly affects infants, children and young adults.

What are new treatment options for Melasma and dark spots on face?


 

Q: "I have a dark spot on my left cheek, my dermatologist says it's Melasma, the hydroquinone cream didn't help what are my options?" Melinda from San Antonio



A: Dr. Reza F Ghohestani, M.D., Ph.D., a renowned dermatologist, and Director of Texas Institute of Dermatology, Laser and Cosmetic Surgery in San Antonio


Melasma is characterized by presence of dark brown spots on sun exposed areas mainly cheeks, upper lip, chin and forehead.  

Melasma and darkening of skin usually develops over the time and its very common in San Antonio and Boerne area. Why some develop Melasma is uncertain. Melasma in South Texas (San Antonio, Boerne) area is more common in Hispanics and Asians and also those with darker skin types.

 In addition to Sunlight, sex hormones are also implicated. Melasma typically occurs after pregnancy or after longterm use of oral contraceptive pills. Other factors that may have a role in development of Melasma include some photosensitizing meds, thyroid or ovarian diseases, and importantly certain cosmetic products. Melasma is rare in young women. Less than 10% of Melasma cases are Men. Pigmentation seen in other diseases such as Addison disease, photosensitivity skin reactions, Discoid Lupus, Mastocytosis and Poikiloderma.






Successful treatment of Melasma requires years of experience. Dr. Ghohestani and his research team at Texas Institute of Dermatology have recently developed I-Bright, a revolutionary laser package for Melasma and dark spots. For more information on I-Bright, please click here

Before development of I-Bright, people had to use topical hydroquinine cream 2-4%, Azelaic Acid, Tretinoin, cryotherapy or a chemical peel without noticing a significant improvement. 
Chemical peels and laser if its not used by an experienced dermatologist or plastic surgeon may cause a number of potential side effects, such as scar formation or hyper pigmentation. Isolated studies suggest that Laser Q-switched 1064-nm Nd:YAG or Fractional Co2 laser can be effective. However, according to Dr. Ghohestani, nothing is comparable to I-Bright for successful treatment of Melasma. Strict Sun avoidance and using a sunblock that contains Titanium or Zinc Oxide is highly recommended before, during and after the treatment.

I live in San Antonio; is Botox or Dysport a good option for my facial wrinkles?




BOTOX Cosmetic, Dysport and Xeomin injectables are great options for treatment of Wrinkles
Texas Institute of Dermatology is a Top Botox Injector in San Antonio and Boerne 

San Antonio Botox Clinic Offers Botox Dysport injections for forehead, around eyes, glabellar, 11s, neck.
BOTOX Injections: Actual Patient Treated by our Dermatologist. BOTOX  cosmetic is a great option for lines on forehead and 11s (between eyebrows)
Nowadays, almost every San Antonio and Boerne citizen knows a friend, a loved one or a celebrity who has received BOTOX, Dysport or Xeomin injection. BOTOX, Dysport and Xeomin only relax muscles located deep under the skin. They are all acting similarly on nerves, said Dr Ghohestani, a renowned dermatologist and director of Texas Institute of Dermatology in San Antonio.

Once the muscles contract, the skin folds and we therefore notice deep lines (wrinkles). These lines include: Glabellar (frown) lines that form between the eyebrows, lines along the nose (bunny lines), lines that stretch across the forehead, crow’s feet that fan outwards from the eyes, marionette lines around the mouth, lines around the lips and neck lines (turtle neck).

With skin aging, these lines gradually become deeper and deeper. If these wrinkles make you feel self-conscious or look older than you feel, BOTOX, Dysport or Zeomin injectables are ideal therapeutic options.
BOTOX treatments have been changing lives for over 10 years, BOTOX cosmetic was initially introduced in the United States by a dermatologic surgeon in 1991. According to a survey published by the American Society of Dermatologic Surgery,  BOTOX and Dysport continues to be utilized by the majority of dermatologists; more than 1.2 million BOTOX and Dysport injections are safely performed.
As one of the top providers of BOTOX in San Antonio, Boerne, Hill Country and Corpus Christi areas, and as a member of Allergan’s  Brilliant Distinctions program, Texas Institute of Dermatology is pleased to offer you $50 off your first BOTOX treatment. If you would like to know whether BOTOX injectable is a right choice for you, please contact our office at 210-698-6777 or info@txid.org; mention discount code “Goo502012″ to receive our special. For more information on BOTOX click here.

Sometimes, BOTOX alone may not be enough to get rid of deep lines, additional procedures such as fractional Co2 laser resurfacing or Renew 360 are required in addition to BOTOX.  Most San Antonio citizens prefer to not have of an artificial frozen look and are hesitant to receive BOTOX or other cosmetic procedures. Dr. Ghohestani's unique approach to analyze your facial muscle movements before any injection ensure an excellent outcome that guarantees a natural look. Please bring your pictures when you were 5, and 10 years younger for the consultation.

Dysport and Xeomin have a very similar mechanism of action to Botox. According to Dr. Ghohestani, Dysport and Xeomin are good options for those who are getting Botox over years so their body is not used to Botox. Additionally, Dysport may provide better results for the crews feet (around the eyes).

If you look for something more permanent, tyou may consider Renew 360. Renew 360 is a novel approach in skin rejuvenation where each layer of skin is treated individually. Renew 360 offers a natural yet refreshed look and is recently developped by Dr. Ghohestani and his research team at Texas Institute of Dermatology. At Texas Institute of Dermatology cosmetic clinic, our top cosmetic dermatologists offer a comprehensive approach to maintain a natural look while rejuvenating the entire skin.

 How does Renew 360 rejuvenate your skin?

Renew 360 combines multiple state-of-the art technologies to treat symptoms of skin aging including: pigmented spots, texture and skin laxity. The treated area gradually rejuvenates months after the treatment. Renew 360 is very safe and appropriate for all skin types though the settings may change according to your skin type. Many individuals have been treated with Renew 360 at our San Antonio/Boerne clinic. Renew 360 consists of four technologies:
  • Microdermoabrasion: A titanium tip removes the superficial layer of the skin and provides a mechanical exfoliation. Microdermabrasion opens up the door in order to maximize the laser light penetration.
  • AFT (Advanced Fluorescent Technology): AFT is an upgraded form of IPL (Intense Pulsed Light).  This innovative technology delivers pulses of light to skin and target the dark pigmented spots and blood vessels. AFT evens out your skin color and stimulate new collagen formation.
  • Accent Elite: Accent Elite is a new technology that delivers radiofrequency energy to facilitate dermal remodeling for skin tightening. Accent Elite firms up your loose skin so you can regain a contoured appearance.
  • Fractional CO2 laser resurfacing: Fractional CO2 laser creates hundreds of microholes on the surface of your skin thereby stimulates new collagen formation deep inside the dermis, and renew the superficial epidermal layer of your skin. Fractional Co2 laser is the latest Co2 technology with significant less downtime and side effects.


What is the difference between Renew 3×60 and Fraxel or Dot Therapy Laser?

Fraxel and Dot therapy laser treatments are a one time skin resurfacing treatment that uses a fractional CO2 technology.  While this skin resurfacing treatment may provide some good results with skin resurfacing, it does require a significant amount of down time. Additionally, the skin tightening provided by Dot therapy or Fraxel is significantly lower as compared to Renew 3×60. Renew 3×60 was designed to ensure a more complete treatment that targets all areas of the skin (texture, fine lines, pigmentation, and skin elasticity) with very little to no down time. Additionally, you will receive the 4 technologies in not one but 3 sessions.  Over years of experience, Dr. Ghohestani and his group designed Renew 3×60 to maximize the outcome and patients satisfaction while minimizing the discomforts and potential side effects. Renew 3×60 allows a complete skin rejuvenation and tightening whereas a single Fraxel or Dot therapy may not be good enough in most cases. Additionally, downtime and potential side effects of Renew 3×60 is significantly less as compared to Fraxel or Dot therapy.
