Top things to know about Olay Regenerist Vitamin C + Peptide 24 MAX Moisturizer
- Olay Regenerist Vitamin C + Peptide 24 MAX Moisturizer is a whipped face cream sold in a jar, listed at $43.99 for 1.7 ounces and usually found for $20 to $29. It is a daily moisturizer with a brightening claim attached, not a treatment, and nothing in it exfoliates or resurfaces.
- Water and glycerin lead the list, with niacinamide fourth and lactic acid fifth, so the hydrating half is solid. The vitamin C is 3-O-ethyl ascorbic acid, a derivative, sitting tenth at an undisclosed amount, with two peptides below it. There is also titanium dioxide, a white pigment, and a citrus fragrance.
A good moisturizer with a brightening claim I would not buy it for. Its vitamin C is 3-O-ethyl ascorbic acid, a derivative with no published clinical trials on skin, sitting tenth at an undisclosed amount — and a jar you open daily is the wrong home for any antioxidant. Buy it for the niacinamide.

Skin fit
Is it right for your skin?
Normal Skin
A straightforward daily cream that hydrates well and layers under sunscreen without arguing with it. Nothing in it needs building up to, and nothing will sting.
Dry Skin
Glycerin sits second and pulls water into the surface cells; the fatty alcohols smooth the surface down. Nothing in it seals strongly, so very dry skin will want something heavier over the top at night.
Sun Damage
This is why most people pick it up, and it is the part to hold loosely. The niacinamide is useful and the base hydrates well, but the vitamin C is a derivative with no published trials on skin that we could find. Treat brightening as a bonus.
Texture
What it feels like on skin.
Cream
Olay Regenerist Vitamin C + Peptide 24 MAX Moisturizer is a light whipped cream that spreads thin and absorbs quickly. A pea-sized amount covers the face. It has a citrus fragrance, which matters if scented skincare bothers you. It leaves a soft finish and sits under makeup without rolling. The instant glow is titanium dioxide, a white pigment on the surface, and it washes off. Every time you open the jar, the vitamin C meets air.

How to apply it
- How muchA pea-sized amount for the face and neck.
- CarefulClose the jar tightly and keep it out of the light. Vitamin C breaks down in air and light even as a stable derivative, and a wide-mouthed jar is the wrong home for it.
What to expect
- What to expectSkin feels softer immediately and looks brighter the same day, which is the pigment. Any real change in tone from the vitamin C is unproven here.
