Can you use retinol and salicylic acid together?
Use at different times
Usually not in the same routine. Most people get better results using retinol and salicylic acid at different times.
Why
Both increase cell turnover and can dry the skin. Together they often lead to peeling, stinging and a weakened barrier.
How to use them
Alternate nights, or use a salicylic acid cleanser in the morning and retinol at night. Stop one if your skin stings.
At a glance
Retinol
- What it does
- A vitamin A derivative that speeds up skin cell turnover. It is one of the most studied ingredients for texture, fine lines and clogged pores.

- PM
- Main watch-out
- Dryness, flaking and stinging are common in the first weeks ("retinization")
Salicylic Acid
- What it does
- An oil-soluble exfoliant that gets into pores, making it a go-to for blackheads, clogged pores and oily skin.
- When to use
- AM/PM
- Main watch-out
- Can dry or irritate, especially combined with other exfoliants
General layering tips
- Introduce one new active at a time and give it 2–4 weeks.
- Patch test new products on a small area for a few days.
- If your skin stings, burns or peels, stop the newest product and simplify.
- Wear broad-spectrum SPF 30+ daily when using retinoids or acids (AAD sunscreen guidance).
