Sunscreens: What to Look For

Sunscreens remain the gold standard for photoprotection.  Do you know which are safest, or ingredients to avoid? Sunscreens are rated according to their sun protection factor (SPF), mode of action (sunblocks vs. sunscreens), and absorption spectrum. Sunscreens primarily absorb the UV light whereas sunblocks, like Zinc Oxide and Titanium Dioxide, reflect the UV light. A broad-spectrum or full-spectrum sunscreen provides protection from both UV-A and UV-B radiation. To protect against the long UV-A wavelengths, the sunscreen should contain Zinc Oxide, Avobenzone, or Mexoryl as an active ingredient. Sunscreens with SPF 30+ filter more than 97% of the UV-B radiation.

It is important to choose a broad-spectrum, waterproof sunscreen. Also, one should stay away from potentially toxic or irritating ingredients such as Oxybenzone (Benzophenones), Retinyl Palmitate, Methylisothiazolinone, Octinoxate, and Octocrylene.  We, at GK Dermatology, have worked hard to identify mineral-containing, broad-spectrum sunblocks that are non-greasy, and do not generate heat in the skin. We believe that sunblocks that are chemical-free generate less heat and sweat than sunscreens because they sit on the skin, and do not significantly penetrate it.Sunscreens (collage edit 2)

The high-quality, chemical-free, sheer sunscreens at GK Dermatology  provide intense photoprotection (SPF 50+), and are easy to apply over moisturizer and under makeup. Therefore, they can be used daily all-year round. Furthermore, our sunscreens contain antioxidants, such as Resveratrol, Embilica, and Green Tea Polyphenols, that combat oxidative damage to the skin which helps in the prevention of skin aging.

  1. GK Dermatology has the most amazing sunscreen. It is unbelievably light and layers beautifully under makeup. I have even used it on my son, who has ultra-sensitive, eczema-prone skin, and it does not break him out. I love the fact that it is chemical-free as well. Everyone should be using it!

  3. Thank you for this very positive feedback. Yes, it is non-greasy and can be used under makeup. It also comes as a spray that can be used neck down. Our patients have been extremely happy with this sunscreen.

  4. I also love the sunscreen! I find it non-irritating as other sunscreens are and goes on weightless.

  5. By far the best sunscreen I have ever used! I use a small amount every morning and the tube lasts 4-5 months. It spreads smoothly and feels like a light moisturizer. I highly recommend it.
