GlossaryUltraviolet Radiation

invisible electromagnetic radiation with shorter wavelengths than visible light

Ultraviolet Radiation (UVR) is a type of electromagnetic radiation that comes from the sun and artificial sources like tanning beds. It has shorter wavelengths than visible light, making it invisible to the human eye, but it can cause skin damage, sunburn, and increase the risk of skin cancer. UVR is also used in medical and industrial applications, such as sterilizing equipment and treating certain skin conditions.

community Tretinoin can make it worse!!!

in Chat 7 upvotes 2 years 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.
