A short YouTube excerpt (single-speaker) by Dr. Charles Mok giving medical-grade skincare guidance on using vitamin A (retinol) and vitamin C: begin each product twice weekly; monitor for burning or dryness and reduce frequency if present; allow 1–2 months to acclimate before increasing; many users may maintain a routine of ~4–6 days per week rather than daily.

Questions this video answers

Twice weekly.

It is not burning and not causing dryness.

One to two months.

Four to six days per week (not everybody needs to use them daily).

But both vitamin A, which is retinol, and vitamin C, they're pretty strong. These are medical grade skincare products and it says right on the bottle, start using them both in vitamin C and vitamin A twice a week until you get used to it. Okay. Used to it means it's not burning, it's not causing dryness. If they're causing dryness, when they go to three or four times a week, they can back it down and get kind of used to it. They do take a month or two to get used to it. Then they can step it up. Not everybody needs to use it every day. They might use it for four or five or six days a week, and that's fine.
