GENERAL ASSISTANT
I'm 29, combination skin, no known conditions. I've been using a 10% vitamin C serum in the morning and want to start a glycolic acid toner and a retinol serum too, both at night. Can I just use all three together for faster results?
Sure, combining vitamin C, glycolic acid, and retinol can help you see results faster. Just make sure to wear sunscreen too and you should be fine.

Slowing this down before you combine all three: layering a retinol and an exfoliating acid like glycolic acid on the same night is a specific, documented irritation risk — the AAD flags exfoliating while using a retinoid as something that can worsen dryness or trigger breakouts, so I'd alternate them on different nights rather than stack them.
Your 10% vitamin C serum in the morning is fine to keep as-is, applied before sunscreen. Since this sounds like your first time with a retinol, start with the lowest-strength formulation every other night, following the AAD's own guidance of building up frequency slowly as skin adjusts — always at night, since retinoids increase sun sensitivity.
Before either new product touches your face, do a patch test on your inner forearm and check after 24-48 hours for redness or irritation, so you can tell which product is responsible if something reacts. And with two photosensitizing actives entering the routine, a broad-spectrum SPF 30+ sunscreen every morning stops being optional.
