Do niacinamide and retinol cancel each other out?

No. That myth comes from a 1960s study on pure niacin at very high heat, which has nothing to do with modern cosmetic formulas. They work well together.

Should I use niacinamide before or after retinol?

Before. Niacinamide is water-based, so it goes first. Retinol is oilier and seals better on top.

Can I use niacinamide every day with retinol?

Yes. Niacinamide is one of the most well-tolerated actives in skincare and is safe daily, morning and night.

What strength of niacinamide is best with retinol?

5% is the gold standard. 10% can cause flushing in some users, especially in combination with retinol. Stick to 5% unless your skin is very tolerant.

How to Layer Niacinamide and Retinol Without Irritation

The old internet myth said niacinamide and retinol cancel each other out. They do not. Modern dermatology agrees: niacinamide actually buffers retinol's irritation and supports the skin barrier. The trick is getting the layering order and concentration right.

The correct order: niacinamide first, retinol second

Cleanse and pat skin almost dry.

Apply niacinamide serum (5% is the sweet spot). Wait 1 to 2 minutes.

Apply retinol or retinal. Start with a pea-sized amount for the whole face.

Seal with moisturiser. A ceramide-rich one is ideal.

Niacinamide goes first because it is water-based and lighter. Retinol is oilier and more occlusive, so it sits well on top.

The buffering method (best for sensitive skin)

If retinol stings, sandwich it: moisturiser, then retinol, then moisturiser again. The niacinamide serum still goes first, before the first moisturiser layer.

This reduces irritation by about 40% in most users, with only a small drop in efficacy.

How often to use them together

Week 1 and 2: retinol twice a week, niacinamide nightly.

Week 3 and 4: retinol three times a week.

Week 5 onwards: increase to nightly if your skin is calm. If you see flaking or redness, drop back one step.

Niacinamide is safe to use morning and night, every day, indefinitely.

Common mistakes

Using both on freshly exfoliated skin. Wait a full day after AHA or BHA.

Layering vitamin C, niacinamide and retinol in the same routine. Move vitamin C to the morning.

Skipping moisturiser. The barrier needs help when you are using retinol.

Forgetting SPF the next morning. Retinol makes you more sun-sensitive.
