Dermaplaning: Dermaplaning uses a surgical scalpel to gently scrape off the top layer of dead skin cells to reveal smoother and brighter skin. It also removes peach fuzz. The benefit is improved skin texture, better product absorption, and younger skin appearance. Performed by dermatologists and with select at-home devices.

Dermatologically Tested: Tested on the skin by a dermatologist. This term usage varies by company or brand. The term does not automatically imply that the product results are “Dermatologist Approved” or “Dermatologist Recommended”.

DHT (dihydrotestosterone): DHT is a hormone which causes hair follicle shrinkage. DHT accumulates at the base of the hair follicle when hair is not washed daily.

Topical products and vitamins can remove or reduce DHT production and accumulation.

Dimethicone: Dimethicone is a type of silicone often used in oil-free moisturizers for slip and hydration.

Dimethylaminoethanol (DMAE): DMAE is useful in supplement and topical form for skin maintenance to maintain muscle and skin firmness. DMAE supplements support muscle tone, including facial muscles.
