What should you not use with vitamin C?
You have a vitamin C serum and want to fit it into your existing routine. But can you use it with retinol, niacinamide and acids? Here’s the short answer and how to avoid irritating your skin.
In short
- Most ingredients can be used in the same routine as vitamin C. It’s mostly a matter of timing.
- Use vitamin C in the morning and retinol or acids in the evening. Start gradually, and cut back if your skin becomes irritated.
- Vitamin C and niacinamide can be used together, and sunscreen should always be part of your morning routine.
Why should you consider what you combine with vitamin C?
Pure vitamin C (ascorbic acid) is delicate. It does not keep well when exposed to air, light and heat1. At the same time, using several strong ingredients at once can irritate the skin, causing stinging, redness or peeling.
It’s rarely dangerous, but it’s frustrating, and it can make you give up a routine that would otherwise benefit your skin. Fortunately, you rarely have to choose. You can often space the ingredients out over the day and introduce new ones gradually.

Can you use retinol and vitamin C together?
Yes. You can have both retinol and vitamin C in your routine, but it’s easiest on your skin to use them at different times of day. Use vitamin C in the morning, when the antioxidant can work while you’re out in daylight. Use retinol in the evening, when it has time to work undisturbed.
Both can make your skin a little sensitive at first. If you’re new to retinol, start with a couple of evenings a week and build up slowly. Read more in our guide to retinol.
- Cleanse your skin with a mild cleanser.
- Apply a couple of drops of vitamin C serum.
- Moisturise with your day cream.
- Protect your skin with sunscreen.
- Cleanse the day away from your skin.
- Use your retinol or your acid, but not both on the same evening.
- Finish with your night cream.
Can you use vitamin C and niacinamide together?
Yes. You may have read that the two cancel each other out. That advice comes from older laboratory experiments with pure substances, not from skincare as you use it. You can safely use them in the same routine. Our Pigmentation Serum actually has both in the same bottle.

Can you use vitamin C with acids?
Acids such as glycolic acid (AHA) and salicylic acid (BHA) remove dead skin cells. Combined with vitamin C, this can be too much for your skin, especially if it’s sensitive. So use acids in the evening or on days when you don’t use vitamin C.
Read more about acids in What you need to know about AHA, BHA and PHA and in our guide to salicylic acid.
Vitamin C and benzoyl peroxide
Benzoyl peroxide is used for spots and can break down vitamin C, stopping it from working as it should. Both can also dry out the skin. Use them at different times of day or on different days.
Vitamin C and copper peptides
If you use copper peptides and want to combine them with vitamin C, follow the product instructions. If the manufacturer advises against using them at the same time, use them at different times of day. You can safely use other peptides, such as Argireline, with vitamin C. Read more in our guide to peptides in skincare.
Myth or fact?

If you use retinol, you can’t use vitamin C.
Myth. You can use both. Use vitamin C in the morning and retinol in the evening.
The more active ingredients, the faster the results.
Myth. Too many at once can irritate the skin. A simple routine you stick to gives the best result.
These go well with vitamin C
- Sunscreen: Vitamin C and sunscreen complement each other. Sunscreen protects against the sun’s rays, and vitamin C is an antioxidant that works together with vitamin E in the skin2.
- Hyaluronic acid: provides moisture and makes it easy to add vitamin C to a simple morning routine. Read more in the guide to hyaluronic acid.
- Vitamin E: is also an antioxidant, and the two work well together.
