Top things to know about CeraVe Vitamin C Serum
- CeraVe Vitamin C Serum is a fragrance free antioxidant serum for the face, in an opaque tube with a pump, about $20 to $25 at drugstores. It is a daily antioxidant and brightening step, not an exfoliant and not a moisturizer, and CeraVe says plainly it is not for the eye area.
- The active is 10% L-ascorbic acid, pure vitamin C rather than a derivative. It needs a low pH to get into skin, and low pH is mildly irritating, which is why the base carries ceramides, cholesterol and phytosphingosine, the fats that hold the surface layer together.
The vitamin C serum to start with. It uses 10% pure L-ascorbic acid, the form with decades of evidence, in an opaque pump that keeps air out — and air is what turns vitamin C useless. Replace it once it darkens to orange. Keep it away from the eye area.

Skin fit
Is it right for your skin?
Sun Damage
Ultraviolet light damages skin partly by creating free radicals, unstable molecules that tear at collagen and cell membranes. An antioxidant donates an electron and stops that chain. Vitamin C is the best-studied one for skin, and this runs it at 10%, inside the range where the evidence holds. It goes under sunscreen, not instead of it.
Hyperpigmentation
Melanin is built by an enzyme called tyrosinase. Vitamin C interferes with it, so less new pigment is made while marked cells at the surface shed on their own schedule. Expect slow, even brightening rather than spot removal, over months.
Post-Inflammatory Hyperpigmentation
The brown mark left by a healed spot is pigment dropped during the inflammation. Vitamin C slows fresh pigment production and soaks up some of the free-radical damage keeping the area inflamed. The ceramides help on skin that is still recovering.
Sensitive Skin
Pure vitamin C stings, and 10% is the gentler end of the effective range. Ceramides and cholesterol support the barrier in the step that stresses it. Try this L-ascorbic acid serum first; if it still burns, the form is wrong for you, not the brand.
Texture
What it feels like on skin.
Serum
Thicker than the word serum suggests. The silicone-heavy base feels like a light cream rather than water. It spreads easily and sinks in within a minute, leaving a slippery finish that can pill if you rub sunscreen on before it dries. It stings for the first minute — that is the low pH, not a bad bottle. The opaque pump keeps air out. If what comes out has turned orange, the vitamin C has oxidized. Replace it.

Try thisWait a full minute before the next layer, and use less. The silicone base is the reason.

The base the other ingredients are dissolved in. Most of it evaporates soon after the product goes on.
A small humectant. It moves into the outer layer of skin and holds water there.
A silicone that smooths the surface and adds to the protective film.
One of the main fats between skin cells in the outer layer. It helps refill gaps in the barrier.
A second skin ceramide. It works with the others to rebuild the barrier.
A long-chain ceramide that helps the barrier fats stack into tight, orderly layers.
A thickener that gives the product its texture.
A fatty alcohol that softens skin and thickens the product. Despite the name, it is not drying.
An emulsifier that also helps the product spread and feel smooth.
A form of hyaluronic acid. Its molecule is large, so it stays on the surface and holds water there.
An emulsifier that helps hold the ceramides in the formula.
A barrier fat that works alongside ceramides. The barrier needs both to repair well.
The preservative. It stops bacteria and mold from growing in the product.
Binds minerals in the water so the preservative works better and the formula stays stable.
A thickener that keeps the texture even.
A building block skin uses to make its own ceramides.
Helps the preservative work and softens the feel of the product.

How to apply it
- How muchA pea-sized amount for the whole face. Keep it out of the eye area.
- CarefulEase in at three mornings a week if your skin is reactive. Do not layer it with a copper peptide serum — copper and L-ascorbic acid cancel each other out.
What to expect
- What to expectNothing dramatic. Tone evens out over two to three months and dark marks fade slowly. Keep it away from heat, and replace it if it turns orange.

Yes.
Will CeraVe Vitamin C Serum sting?
