Retinol and tretinoin are both retinoids which treat signs of aging.
Retinol: Toss

  • Retinol is a weaker retinoid that is more gentle on the skin, but needs more time to see results. It is not proven to work.

Tretinoin: Use

  • Tretinoin a stronger retinoid that is prescription only, allowing you to see significant results in a much shorter amount of time. It is proven to work. That’s why tretinoin is the key ingredient in Collagen Constructor.
