This is the classic VT retinol, Cica Reti-A, and the Collagen Essence from the same series. Cica Reti-A is 0.1, so it's a safe concentration for those who are just starting to use retinol. The Collagen Essence is perfect for moisturizing, and it's recommended to use it to seal in the moisture. Both are brand new and unopened. The expiration dates are good until 2026. I will ship these as is. Type: Serum/Essence Popular Series: CICA RETI-A Ingredients: Retinol
