GlossarySun Damage (Ultraviolet-induced damage)

harm caused by UV radiation leading to skin and hair issues

Sun damage, also known as photodamage or UV damage, refers to the harm caused to the skin and hair by prolonged exposure to ultraviolet (UV) radiation from the sun. This can lead to a range of issues, including sunburn, premature aging (such as wrinkles and age spots), and an increased risk of skin cancer. UV radiation can also weaken hair structure, leading to dryness, brittleness, and color fading.

community Tretinoin can make it worse!!!

in Chat 7 upvotes 1 year ago

Tretinoin may enhance minoxidil's effectiveness for those not responding to minoxidil alone, but it could reduce efficacy for some who are already responding to minoxidil. Tretinoin requires careful use, including skin moisturizing and sun protection due to increased sensitivity.
