Morning routine : - Vit C ( L- ascorbic acid) - Niacinamide - CeraVe Thick moisturizer - SPF 50 sunscreen

Night routine : - Elf double cleanse - CeraVe foaming face wash - 5 nights Tretinoin / 1 night lactic acid / 1 night glycolic acid - COSRX snail serum - CeraVe Thick moisturizer

Where can I use Argireline + Matrixyl in my routine. Don't think I can pair it with Vit C / lactic and glycolic acid. Not sure if pairing with Tretinoin is an issue.
