Drunk Elephant Protini Review: What $72 Buys in a Peptide Cream

Drunk Elephant Protini Polypeptide Cream is a light, fragrance-free gel-cream built around nine signal peptides, synthetic growth factors and amino acids. It suits normal, combination and mildly dry skin that wants a comfortable daily moisturizer with firming-focused extras. The catches are the price, $72 for 1.69 oz on drunkelephant.com as of November 2026, and the fact that its firming claims rest on the brand's own unpublished study.

Before you buy, you can scan the jar's barcode or label with the ingredient scanner in Pori to check how its ingredients are flagged for your skin type.

Below we go through the full ingredient list, what the research on peptides and growth factors does and doesn't show, who should buy it and who should skip it, every size with its price per ounce, how to use it, and four alternatives. We compared published ingredient lists, brand claims and listed prices; we did not test these products on skin.

What is Drunk Elephant Protini Polypeptide Cream?

It's Drunk Elephant's peptide moisturizer for the face. The brand's site now sells it as the Protini Polypeptide Firming Refillable Moisturizer, a refillable jar of the same gel-cream most people still call Protini Polypeptide Cream. Drunk Elephant says it visibly firms skin, supports healthy collagen production, and reduces the look of texture, fine lines, wrinkles and sun damage.

What's in Protini? The full ingredient list

Drunk Elephant lists the ingredients as water, dicaprylyl carbonate, glycerin, cetearyl alcohol, cetearyl olivate, sorbitan olivate, Sclerocarya birrea seed oil, Bacillus/folic acid ferment extract, Nymphaea alba root extract, sh-oligopeptide-1, sh-oligopeptide-2, sh-polypeptide-1, sh-polypeptide-9, sh-polypeptide-11, copper palmitoyl heptapeptide-14, heptapeptide-15 palmitate, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, alanine, arginine, glycine, histidine, isoleucine, phenylalanine, proline, serine, threonine, valine, acetyl glutamine, coconut alkanes, coco-caprylate/caprate, sodium hyaluronate, aspartic acid, linoleic acid, linolenic acid, lecithin, butylene glycol, polyvinyl alcohol, sodium lactate, sodium PCA, PCA, sorbitan isostearate, carbomer, polysorbate 20, polysorbate 60, lactic acid/glycolic acid copolymer, hydroxyethyl acrylate/sodium acryloyldimethyl taurate copolymer, xanthan gum, isomalt, 1,2-hexanediol, caprylyl glycol, chlorphenesin, phenoxyethanol, tocopherol, sodium benzoate, phenylpropanol, glyceryl caprylate and Symphytum officinale callus culture extract. Grouped by job:

• The moisturizing base: water, glycerin and light emollients (dicaprylyl carbonate, coconut alkanes, coco-caprylate/caprate), thickened with cetearyl alcohol, a fatty alcohol that isn't drying, and the olive-derived emulsifiers cetearyl olivate and sorbitan olivate.
• Marula oil (Sclerocarya birrea seed oil): a plant oil, seventh on the list, which gives the gel-cream some slip and richness.
• Synthetic growth factors: the five "sh-" ingredients. The prefix marks synthetic human-identical peptides, and Drunk Elephant describes them as "safe, synthetic growth factors."
• Signal peptides: copper palmitoyl heptapeptide-14, heptapeptide-15 palmitate, palmitoyl tetrapeptide-7 and palmitoyl tripeptide-1. The last two are the pair often sold as Matrixyl 3000.
• Amino acids: alanine, arginine, glycine, histidine, isoleucine, phenylalanine, proline, serine, threonine, valine and aspartic acid, plus acetyl glutamine. Amino acids are part of the skin's natural moisturizing factor, so they work mainly as humectants.
• Other humectants: sodium hyaluronate (a form of hyaluronic acid), sodium PCA, PCA, sodium lactate, butylene glycol and isomalt.
• Plant extracts: Nymphaea alba root extract (the brand's "pygmy waterlily"), a soybean folic acid ferment and comfrey (Symphytum officinale) callus culture extract.
• Lactic acid/glycolic acid copolymer: a polymer, not free acids. It doesn't exfoliate the way a lactic or glycolic acid serum does.
• Texture and stability: carbomer, xanthan gum, polyvinyl alcohol, polysorbates, lecithin, and linoleic and linolenic acids.
• Preservatives: 1,2-hexanediol, caprylyl glycol, chlorphenesin, phenoxyethanol, sodium benzoate, phenylpropanol and glyceryl caprylate, with tocopherol as an antioxidant.

There's no fragrance, essential oil or silicone on the list. Drunk Elephant doesn't publish the concentration of any peptide or growth factor.

Do peptides and growth factors actually work?

Signal peptides

Peptides in skincare fall into a few groups. A dermatology review sorted the topical peptides used against skin aging into signal peptides, enzyme-inhibitor peptides, neurotransmitter-inhibitor peptides and carrier peptides. Signal peptides, the kind Protini leans on, are meant to prompt skin cells to make more collagen. Whether a peptide works in a finished cream depends on its dose and on reaching the right layer of skin, and Drunk Elephant doesn't disclose the doses. Our guide to peptides in skincare goes through the evidence peptide by peptide, and copper peptides covers the copper-bound kind.

Growth factors

Growth factors are signaling proteins involved in wound healing. A review of topical and injectable growth factors found evidence of levels II and III supporting topical growth factors for skin rejuvenation, mostly for factors from human fibroblast secretions or snail secretions, and noted gaps between lab findings and proven clinical benefit. Those studies didn't test Protini's synthetic versions, so the most we can say is that the category is plausible and still thinly studied.

Drunk Elephant's own results

Drunk Elephant reports that in a clinical study of 31 people over 8 weeks, 96% showed improvement in tone, radiance and luminosity, 93% in texture and 90% in hydration. We couldn't find that study published, and it doesn't say whether there was a comparison cream. Any decent moisturizer improves hydration and texture, so these numbers don't isolate what the peptides add.

What has stronger evidence for aging skin

If firmness and lines are your main goal, retinoids have the deepest research. A review of clinical studies found that many natural and synthetic retinoids have shown histological and clinical improvement in aging skin, with tretinoin the most studied, and retinol and retinaldehyde considerably less irritating than tretinoin. Daily sunscreen matters even more. Protini can sit alongside both as the moisturizer step. Start with our retinol for beginners guide.

Who is Protini for, and who should skip it?

It suits you if you:

• Have normal, combination or slightly dry skin and like a light gel-cream under sunscreen or makeup.
• React to fragrance or essential oils and want a moisturizer free of both.
• Already use a retinoid or vitamin C and want a moisturizer with peptides. Drunk Elephant says it can be used, or mixed, with its vitamin C and retinol products.
• Want to try peptides in a moisturizer you'll use twice a day anyway, which is how most peptide studies are run.

Look elsewhere if you:

• Have very dry or eczema-prone skin: it's a light gel-cream. Drunk Elephant itself points chronically dry skin to its richer creams; our best moisturizer for dry skin list has cheaper ones.
• Want proven firming results: the evidence is brand-run and the actives are undisclosed in dose; a retinoid plus sunscreen has more support.
• Are on a budget: at about $43 an ounce, you're paying for the peptide mix and the brand.
• Are very oily or acne-prone: marula oil sits high on the list. Many people tolerate it, but patch test first, or look at our moisturizers for oily skin.

How much does Protini cost?

As of November 2026, drunkelephant.com lists four sizes.

The Big size has the lowest price per ounce while it's available. If you already own the jar, the refill saves $9 on each repurchase.

How do you use Protini?

1. Apply it morning and night to a clean, dry face, after any serums.
2. In the morning, follow with sunscreen. Our guide to how much sunscreen to use shows the amount for face and neck.
3. If you use vitamin C, apply it first in the morning. Drunk Elephant says the two are safe together.
4. At night, it can go over a retinoid. Drunk Elephant says it can be used or mixed with its retinol treatments.
5. Give it at least 8 weeks, the length of the brand's study, before you judge it.

What are the best alternatives to Protini?

• The Ordinary Multi-Peptide + HA Serum: seven named peptides, including palmitoyl tripeptide-1 and palmitoyl tetrapeptide-7, with hyaluronic acid, at $19.90 for 30 ml as of November 2026. Layer it under a plain moisturizer.
• Olay Regenerist Micro-Sculpting Serum Fragrance-Free: palmitoyl pentapeptide-4 with niacinamide in a serum that doubles as a light moisturizer; see our best peptide serum roundup for prices.
• Medik8 Liquid Peptides: a multi-peptide serum the brand pairs with vitamin C and vitamin A, also covered in our peptide serum roundup.
• Drunk Elephant Lala Retro Whipped Moisturizer: the brand's richer cream with a triple-ceramide blend and plant oils, at $68, for skin that finds Protini too light.

Is Drunk Elephant Protini worth it?

As a moisturizer, Protini is pleasant and thoughtfully made: a light gel-cream with many humectants, a modest amount of oil, and no fragrance or essential oils. As an anti-aging treatment, it's harder to judge, because the peptide and growth factor doses are undisclosed and the results come from the brand's own study. Buy it if you like the texture and the price fits. If firming is the goal, a retinoid at night and sunscreen every morning will do more, and a cheaper peptide serum under any good moisturizer gets you most of the same ingredients.
