Dermatologist Dr. Dray answers skincare questions from followers in this Q&A, covering lactic acid vs glycolic acid, laser treatments for aging skin, sunscreen reapplication, eyebrow hair loss, keratosis pilaris, azelaic acid, urea, and fluorescent light exposure.
In this video, Dr. Dray discusses whether 12% ammonium lactate, such as AmLactin, can improve dermal thickness and collagen-related signs of aging, and how its potential benefits compare with glycolic acid. She also explains why the evidence for at-home lactic acid products differs from the evidence for high-strength glycolic acid chemical peels performed in a medical setting.
She also answers whether Fraxel laser is worth considering for Fitzpatrick skin type IV, especially for someone concerned about post-inflammatory hyperpigmentation, and compares it with the gentler 1064 nm Laser Genesis treatment.
Other questions include whether sweating makes sunscreen reapplication less effective, whether eyebrow hair can regrow after scarring from trichotillomania, whether laser hair removal can cause keratosis pilaris, and whether urea and azelaic acid can be used together for KP.
Finally, Dr. Dray explains whether spending eight hours under fluorescent office lighting can contribute to wrinkles, sagging, or premature skin aging.
