Hedge & Hedge Pharmaceutical LLP Tretinoin Cream USPIngredients explained
- 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)
It's the acronym for Butylated Hydroxy Toluene. It's a common synthetic antioxidant that's used as a preservative.
There is some controversy around BHT. It's not a new ingredient, it has been used both as a food and cosmetics additive since the 1970s. Plenty of studies tried to examine if it's a carcinogen or not. This Truth in Aging article details the situation and also writes that all these studies examine BHT when taken orally.
As for cosmetics, the CIR (Cosmetic Ingredient Review) concluded that the amount of BHT used in cosmetic products is low (usually around 0.01-0.1%), it does not penetrate skin far enough to be absorbed into the bloodstream and it is safe to use in cosmetics.
