L'Oreal Triple Power moisturizer: what's really in the Revitalift cream

The L'Oreal Triple Power moisturizer (full name: Revitalift Triple Power Anti-Aging Moisturizer) is one of the best-selling drugstore face creams in the US, and searches for it tripled this week. It costs $27.99 for 1.7 oz, and the box promises to reverse up to 10 years of wrinkles.

The "triple power" is pro-retinol, vitamin C and hyaluronic acid. We read the full ingredient lists for all three versions on L'Oreal's US site and the clinical paper the brand points to. Here's what's in the jar, how strong those three actives really are, and who it suits.

Read the label in order and the cream is mostly water, glycerin and light emollients (isohexadecane and isopropyl isostearate), followed by niacinamide, a starch powder, nylon-12, dimethicone and fatty alcohols. That's a solid, well-built moisturizer base. Glycerin draws water into the skin and dimethicone and the emollients slow its escape.

Niacinamide sits fifth on the list, which makes it one of the more meaningful ingredients in the jar, even though L'Oreal doesn't put it in the name. It also contains a little capryloyl salicylic acid (a gentle salicylic acid relative), caffeine, vitamin E and adenosine.

Nylon-12, polyethylene, titanium dioxide and synthetic fluorphlogopite are soft-focus powders and light-reflecting minerals. They blur texture and add a bit of glow the moment you put it on, which is part of why skin looks better on day one.

"Pro-retinol" is retinyl palmitate, and it's near the very end of the ingredient list, after the sodium hyaluronate. Retinyl palmitate is the gentlest form of vitamin A. Your skin has to convert it to retinol and then to retinoic acid before it does anything, and lab and skin studies show it gets in less well and does less than retinol does.

The vitamin C is ascorbyl glucoside, a stable form that your skin slowly turns into vitamin C. It also appears low on the list, below caffeine. L'Oreal doesn't state a percentage for either one.

So the three "powers" aren't equal. Hyaluronic acid and glycerin give real hydration. The pro-retinol and vitamin C are present in small, gentle amounts. That's why it's easy to tolerate, and also why it isn't a substitute for a proper retinol or a vitamin C serum.

The product page says it's "clinically tested to reverse up to 10 years of wrinkles" and footnotes the claim as "based on multiple clinical studies." The page doesn't explain how years were measured.

The published study the brand links to was written by L'Oreal employees and tested a cream with ascorbyl glucoside, retinyl palmitate and hyaluronic acid. In 53 women aged 35 to 55 who used it twice a day for 4 weeks, graders scored fine lines and wrinkles about 26 to 29% lower and roughness 44% lower. In a separate test on 26 women's forearms, hydration rose 46% within 15 minutes and stayed up for 24 hours.

There was no comparison group using a plain moisturizer, and the authors say themselves that this makes it hard to credit the actives. Any good moisturizer makes skin less rough and fine dehydration lines less visible within days. The results are believable for a moisturizer. They don't show that the cream reverses aging.

L'Oreal now markets Triple Power as "a great support for GLP-1 users" with sagging skin after rapid weight loss. That claim comes from a home-use survey of 102 women on GLP-1 medicines who rated their own skin after 4 weeks. Most were satisfied, but there was no control group and no measurements.

Loose skin after big weight loss is about lost fat and volume under the skin. A moisturizer can make the surface look smoother and more hydrated. It can't replace lost volume.

The original and the fragrance-free versions share the same base. The original adds fragrance plus the fragrance allergens benzyl salicylate, coumarin and linalool. If you have sensitive skin or eczema, pick the fragrance-free one; it's the same price.

The SPF 30 version ($29.99) is a different formula. It swaps in squalane, alcohol, boron nitride and acetyl hexapeptide-8 (Argireline), and it still contains fragrance. It's meant for mornings only. To get the SPF on the label you need a generous layer on your face and neck and you need to reapply in the sun, which few people do with a moisturizer.

• Dry, normal or mature skin that wants one easy cream: the fragrance-free version morning and night is a sensible, affordable pick. Add a separate broad-spectrum SPF 30 or higher in the morning.
• If you want real retinoid results: use a retinol or adapalene product at night and treat Triple Power as the moisturizer on top. Don't expect the pro-retinol in it to do that job.
• Oily or acne-prone skin: the texture is fairly rich. Try it at night first, or choose a lighter gel moisturizer.
• Sensitive or eczema-prone skin: avoid the original and the SPF version because of the added fragrance. Patch test the fragrance-free one on your inner arm for a few days.
• Already using a vitamin C serum or niacinamide serum: that's fine. The amounts in Triple Power are gentle, so layering usually isn't a problem.

Glycerin and hyaluronic acid pull water into the top layer of skin, and dimethicone and emollients slow water loss. Better-hydrated skin reflects light more evenly and fine lines look shallower, which is most of what you see in the first week.

Retinyl palmitate has to be converted twice in the skin before it acts like retinoic acid, the form that has strong evidence for wrinkles, so its effect at a low concentration is mild. Niacinamide has decent evidence for evening tone and improving the look of aging skin at around 4 to 5%. Ascorbyl glucoside is a stable vitamin C derivative with much less clinical data than pure vitamin C.

• Hydration and smoother-looking skin within days, from glycerin, hyaluronic acid and the emollient base.well-supported ingredients
• Niacinamide for a more even-looking tone with steady use.limited evidence
• A modest drop in graded fine lines over 4 weeks, as in the brand's own uncontrolled study.limited evidence
• Pro-retinol and vitamin C at these levels doing what a retinol or vitamin C serum does.insufficient evidence

• Any independent or vehicle-controlled trial of the L'Oreal Triple Power moisturizer.
• The "reverses up to 10 years of wrinkles" claim; the product page doesn't say how it was measured.
• Firming or lifting sagging skin in GLP-1 users; the evidence is a self-rated survey with no control group.
