-------------
Tretinoin (a metabolite of vitamin A) is the gold standard anti-aging ingredient that is also FDA-approved (and it's the only one so far!)
It's an all around skin issue fixer as it works at the skin cell level and makes your skin cells behave in a healthy and normal way
It makes the skin less wrinkled, firmer, smoother and tighter, everything you could want from an anti-aging ingredient
It's also an effective acne treatment. It normalizes keratinization and makes the pores produce less sebum
It's also a skin lightener though not as effective as gold-standard hydroquinone.
Side effects with tretinoin are very common. Irritation, skin flaking, redness, and drier skin are usual
Do not use tretinoin (or any form of retinoids) while pregnant
To minimize side effects introduce tretinoin slowly into your routine (see more how to use tips in geeky details)
