Vitamin C Serum: Before or After Moisturizer?

Skincare layering follows one simple principle: thinner products before thicker ones. For vitamin C, that means before moisturizer in almost every routine.

The standard order

After cleansing and any toner, apply vitamin C serum to clean, slightly damp skin. Wait about a minute, then follow with moisturizer. Finish with sunscreen in the morning.

Why this sequence works

Serums are designed to penetrate. Moisturizers form a more occlusive layer. Reversing the order can block the serum from doing its job.

When you might tweak it

Very dry or reactive skin sometimes benefits from a thin moisturizer first as a buffer, then vitamin C, then a second moisturizing layer. This sandwich technique reduces irritation while keeping the serum effective.

A simple morning sequence

Cleanser, our Vitamin-C Revitalizing Serum, moisturizer, sunscreen. The whole thing takes about three minutes.

Frequently Asked Questions

Can I mix vitamin C into my moisturizer?

Possible, but it dilutes the active and can shift the pH. Layering is more reliable.

How long should I wait between layers?

About a minute is plenty for vitamin C to settle before the next product.

Does the skin need to be damp or dry?

Slightly damp can help absorption, but fully dry also works. Avoid applying to dripping wet skin, which dilutes the serum.
