I currently use skin signals cream every other night (alternating with lacsal). I would like to add a retinol product, but don't know where to put it. My morning routine is a green tea serum alternating every other day with a vit c serum. I found a retinol product I would like to try (ingredients below). Could I use this on the same nights I use my SS cream?


ingredients for Topix Replenix All Trans Retinol Smoothing Serum 3X

Cyclopentasiloxane, Dimethicone Crosspolymer, Cyclomethicone, PEG/PPG 18/18 Dimethicone, Caffeine, Camellia Sinensis (Green Tea) Polyphenols, Retinol, Polysorbate-20, Purified Water, Hyaluronic Acid

Dear weluvnik:

This seems to be a retinol product formulated with hyaluronic acid - Although we do not agree with some of the compounds used in this formula, you could use it along with copper-peptides, if you choose to do so.

We'd recommend to apply Skin Signals Cream very lightly first.

For more information see:
