AHA'S /BHA'S inactivate retinols
1. Resorcinol + Hydroquinone
when used in conjunction with hydroquinone, resorcinol has been shown to cause a rare permanent darkening of the skin in patients with darker skin types (especially South Africans). The effect typically appears after six months of continual resorcinol use.
2. Niacinamide + Sirtuins
Niacinamide wants to increase cell metabolism, while sirtuins want to decrease it.
4. Retinoids + Vitamin C
Vit c affects pH and retinol has to be at a specific pH to function
5. Exfoliants + Glycolic Acid or Retinoids
Glycolic acid is the most common of all the alpha hydroxy acids. Both glycolic acid and retinoids work by increasing cell turnover and thinning the stratum corneum (the uppermost layer of the skin). By exfoliating that top layer of the skin, glycolic acid and retinoids smooth the skin, decrease fine lines and wrinkles, and increase skin firmness by enhancing collagen production.
