Anti-wrinkle ingredients: which ones really work according to studies

An anti-wrinkle product label may list thirty different names, and almost all are presented as game changers. But clinical studies support only a few: sun protection, retinoids, peptides, vitamin C, niacinamide, and hyaluronic acid. Everything else may improve a formula, but that’s not where wrinkle-reducing results come from. The point isn’t to know more ingredients, but to recognize the ones that have evidence.

The short answer: the anti-wrinkle ingredients with the strongest evidence are sun protection, retinoids, biomimetic and signal peptides, vitamin C, niacinamide, and hyaluronic acid, provided they’re present in useful amounts, that is, among the first ingredients on the INCI list. LeLang Skin Care’s Multi Peptide Lift Formula, available in pharmacies and drugstores, is a high-concentration serum of biomimetic peptides developed according to this principle.

Quick guide

Ingredient What it does for wrinkles Level of evidence When to use
Sun protection Prevents photoaging 4.5-year randomized study Every morning
Retinol and retinoids Stimulate procollagen and the dermal matrix Controlled studies, including on very mature skin Evening, gradually
Peptides Smooth expression lines or signal fibroblasts to repair Placebo-controlled studies for some peptides Morning and evening
Vitamin C Antioxidant, supports collagen synthesis Six-month double-blind study Preferably in the morning, under SPF
Niacinamide Fine lines, dark spots, elasticity, skin barrier 12-week controlled study Morning and evening
Hyaluronic acid Hydrates and smooths dehydration lines 60-day randomized study Morning and evening, on damp skin

How can you tell if an anti-wrinkle ingredient really works?

There are three levels of evidence to distinguish. The first is laboratory testing on cells or reconstructed skin: it tells you an ingredient can do something, not that it will do it in a cream. The second is a study by the ingredient’s manufacturer involving volunteers, often small but useful. The third, and most reliable, is the controlled study: half the face or half the participants receive the active ingredient, while the other half receive the same formula without it, and the evaluators don’t know who used what.

Then there’s the question of quantity. An active ingredient with excellent evidence won’t do anything if it’s present only in trace amounts. On the label, ingredients are listed in descending order of quantity down to 1%; below that threshold, they can appear in any order. If the active ingredient promised on the packaging comes after preservatives and fragrance, its concentration is minimal. This is the simplest way to make an initial selection, even before looking at the price.

Is sunscreen really the first anti-wrinkle ingredient?

Yes, and it’s the only one with a long-term study involving ordinary people. In Australia, 903 adults under 55 were randomly divided into two groups: those who applied broad-spectrum sunscreen every day and those who used it only when they thought it was necessary. After four and a half years, skin aging, measured using skin surface replicas, had not measurably increased in the daily-use group and was 24% lower than in the other group.

No serum has this kind of evidence. That’s why every discussion of anti-wrinkle products starts here: an active ingredient that repairs skin at night is fighting an uphill battle if the skin continues to receive UVA rays during the day without sunscreen. The reasons for wearing it in winter too are explained in the article on the best sunscreen for the face.

Why is retinol considered the gold standard for wrinkles?

Because it’s one of the few cosmetic ingredients with direct evidence of its effects on the dermis. In a University of Michigan study of 36 people with an average age of 87, a retinol lotion applied to one arm for 24 weeks, compared with the same lotion without the active ingredient on the other, significantly improved fine wrinkles. Biopsies showed more type I procollagen and more glycosaminoglycans, the molecules that retain water in the skin.

The limitation is tolerability: redness and flaking are common during the first few weeks. Start using it in the evening, two or three times a week, and increase gradually. In Europe, the permitted concentrations in cosmetics are regulated and will change in 2027: if you want to understand whether it’s really essential, you can find my perspective in the article Is retinol really essential?

Peptides: What types are there, and how do they work on wrinkles?

“Peptide” isn’t an ingredient, it’s a family. A review by the University of California divides them into four groups based on their mechanism:

  • Signal peptides, such as Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7 (the complex known as Matrixyl®): they signal fibroblasts to produce components of the dermal matrix.
  • Expression-line-reducing peptides, such as Acetyl Hexapeptide-8 (Argireline®): they work on expression lines. In a randomized, placebo-controlled study of 60 people, applying it twice a day for four weeks reduced the appearance of fine lines around the eyes.
  • Carrier peptides, which transport trace elements such as copper.
  • Enzyme-inhibiting peptides, which slow collagen breakdown.

The practical takeaway: a formula combining peptides from different groups works on multiple fronts, and peptides are generally well tolerated, so they can also be used when the skin cannot tolerate retinol. The guide on what peptides are in cosmetics and the one on Acetyl Hexapeptide-8 go into more detail.

Does vitamin C help with wrinkles or just dark spots?

It does both. Vitamin C is an antioxidant and a cofactor for the enzymes that stabilize collagen. In a six-month French double-blind study, a 5% ascorbic acid cream applied to photoaged necks and arms improved the overall clinical score, increased microrelief density, and reduced deep furrows compared with the same cream without vitamin C; signs of elastic tissue repair were visible under an electron microscope.

The problem with pure ascorbic acid is stability: it oxidizes easily. That's why formulas often use more stable derivatives, such as ethyl ascorbic acid or sodium ascorbyl phosphate. It is best applied in the morning, under sunscreen, because it boosts its protective effects. How to choose one is explained in the guide to vitamin C serums.

Niacinamide and hyaluronic acid: what do they really do for wrinkles?

Niacinamide is vitamin B3. In a study of 50 women with signs of photoaging, applying it at 5% for 12 weeks to half the face reduced fine lines and wrinkles, dark spots, blotchy redness, and sallowness, and improved elasticity as measured by an instrument. It is well tolerated and supports the skin barrier, so it pairs well with almost anything.

L'Hyaluronic acid draws water into the stratum corneum. In a study of 76 women aged 30 to 60, all 0.1% formulations improved hydration and elasticity around the eyes compared with placebo; only the low-molecular-weight formulations also reduced wrinkle depth after 60 days. It is not an anti-wrinkle ingredient in the same sense as retinol, but it visibly smooths dehydration lines and prepares the skin for other active ingredients.

Which ingredients should you avoid in an anti-wrinkle serum if you have oily skin?

There are no forbidden ingredients for oily skin, just choices that aren’t a good fit. Here’s what to watch out for:

  • Highly occlusive butters and oils high on the ingredient list, such as shea butter or coconut oil: on skin that already produces a lot of sebum, they feel heavy and can contribute to comedones.
  • Rich textures designed for dry skin: water-based serums or lightweight gels are better.
  • Large amounts of denatured alcohol: it gives an immediate mattifying effect but dries and irritates the skin, which responds by producing more sebum.
  • Too many exfoliating actives at once: acids and retinoids on the same evening can irritate oily but sensitive skin more than they help.

There’s a dedicated guide to the first wrinkles on combination or oily skin: effective ingredients.

How do you combine anti-wrinkle ingredients in your routine?

The rule I follow is to divide the routine between morning and evening.

  1. Morning: gentle cleansing, vitamin C or niacinamide serum, peptide serum if you use it twice a day, moisturizer, sunscreen.
  2. Evening: cleanse thoroughly, apply a peptide serum, use retinol two or three evenings a week on the evenings you’ve planned for it, then apply cream.
  3. Introduce one new active ingredient at a time, allowing at least four weeks before evaluating it.

Peptides and hyaluronic acid work well with everything. Vitamin C and niacinamide can be used together. Retinol and exfoliating acids, however, are best used on different evenings.

Frequently asked questions

Which ingredients should you look for in a good anti-wrinkle cream?

Those with controlled studies on wrinkles: retinol, biomimetic and signaling peptides, vitamin C, niacinamide, and hyaluronic acid, near the top of the INCI list. During the day, always follow up your cream with broad-spectrum sun protection, which has the strongest evidence for preventing wrinkles.

Which active ingredients are effective in anti-wrinkle creams?

Retinol, which improved fine wrinkles and increased procollagen in a study of people with an average age of 87; peptides, such as Acetyl Hexapeptide-8 for expression lines; vitamin C, niacinamide, and low-molecular-weight hyaluronic acid. The amount and stability of the ingredients in the formula matter too.

Which ingredients should you avoid in anti-wrinkle serums for oily skin?

Highly occlusive butters and oils near the top of the INCI list, rich textures designed for dry skin, and large amounts of denatured alcohol. Water-based serums with peptides, niacinamide, and hyaluronic acid are a better choice; introduce retinol and acids gradually and use them on different evenings.

Which active ingredients are recommended for lip wrinkles?

Peptides that reduce facial muscle contractions, such as Acetyl Hexapeptide-8 and Acetyl Hexapeptide-1, hyaluronic acid for dehydration lines, and daily sun protection, because the upper lip is highly exposed. LeLang Skin Care’s Multi Peptide Lift Formula is also formulated for the lip contour.

Which ingredients should you look for in an anti-wrinkle eye cream?

Specific peptides such as Acetyl Hexapeptide-8 for crow’s feet and Acetyl Tetrapeptide-5 for under-eye bags, hyaluronic acid, caffeine, and soothing ingredients in a lightweight texture. Retinol near the lash line should be used with great caution.

Can you use retinol and peptides together?

Yes. Peptides are well tolerated and don’t interfere with retinol; many routines use both in the evening, or peptides morning and evening and retinol only on certain evenings. If the skin becomes irritated, reduce how often you use retinol and keep using peptides.
