Current product pages: Drunk Elephant Protini and Naturium Multi-Peptide Moisturizer.
Drunk Elephant Protini and Naturium Multi-Peptide Moisturizer are both peptide moisturizers, but their ingredient lists are different. Protini’s U.S. page lists a 50 ml package at $72 and says it contains nine signal peptides. Naturium’s U.S. page lists a 50 g package at $20 and shows three named palmitoyl peptides, niacinamide, panthenol, vitamin C derivative, jojoba oil, and squalane.

That makes Naturium a lower-priced alternative for someone shopping the general category, not evidence that it recreates Protini’s formula or appearance claims. There is no independent, side-by-side trial establishing matching results.
The package prices are easy; the formulas are not
Prices and displayed labels were checked on August 12, 2026. The packages use different units (ml and g), so the per-package comparison is more honest than presenting them as the same volume.
| Product | Listed size and price | Approx. listed price per 50 ml/g | Formula and package details shown by the brand |
|---|---|---|---|
| Drunk Elephant Protini Polypeptide Firming Refillable Moisturizer | 50 ml, $72 | $72.00 | Nine signal peptides, amino acids, pygmy waterlily; pH 4.0; free of essential oils, silicones, fragrance/dyes, and solvent alcohols; refill option shown |
| Naturium Multi-Peptide Moisturizer | 50 g, $20 | $20.00 | Palmitoyl tripeptide-5, palmitoyl tripeptide-1, palmitoyl tetrapeptide-7, niacinamide, panthenol, jojoba oil, squalane, and vitamin C derivative; pH 4.8–5.8; fragrance-free |
On the listed package prices, Protini is 3.6 times more expensive. This is not cost per use: no independent amount-per-application or duration measurement was made.
What Protini adds for the extra $52
Protini’s premium is attached to a particular formula and package. The brand identifies nine signal peptides, gives a pH of 4.0, describes a lightweight gel-cream, and offers a 50 ml refill format. It also reports a 31-person, eight-week clinical study with brand-reported percentages for tone, texture and hydration; the page does not provide an independent head-to-head comparison or enough protocol detail to treat that study as comparative evidence. Drunk Elephant product page
The premium also buys the specific ingredient list: Protini includes multiple signal peptides and a pygmy waterlily extract, while Naturium’s displayed list is built around three named palmitoyl peptides and a broader emollient and brightening blend. More ingredients or a higher price does not, by itself, prove a better cosmetic outcome.
When Naturium is the more sensible buy
Naturium can replace the basic moisturizing step for someone who wants a mid-weight peptide product at a lower price. Its brand page says it is fragrance-free, gives a formula pH range of 4.80–5.80, and reports an eight-week clinical study for the look of fine lines and wrinkles. The page does not identify the sample size in the accessible product copy, so that claim should not be treated as independently verifiable evidence. Naturium product page
It cannot replace Protini’s exact nine-signal-peptide formula, pH 4.0 claim, refill system, or fragrance-and-silicone-free wording. Naturium also has a different displayed ingredient order and different brand claims. The lists can tell you what the brands disclose; they cannot predict which texture you will prefer without use.

The practical choice
Choose Naturium if the budget matters, you want a fragrance-free peptide moisturizer, and a 50 g package is enough for your comparison. Choose Protini if you specifically value its disclosed peptide blend, pH 4.0, refillable package, or the product’s own brand story enough to pay more.
Skip Protini if the price is likely to make you ration moisturizer or resent the purchase. Skip Naturium if you are choosing Protini for its exact nine-peptide formula, refill format, or its specific brand-reported testing. Neither decision needs a copy claim.

Evidence grade: mixed
The prices, sizes, displayed INCI lists, package formats, and brand claims are directly checkable on the two U.S. product pages. The performance comparison is unresolved: each brand reports its own study or claim, while no independent head-to-head study was located for this page. Read the cheaper option as a different product that may fit the same routine slot, not as a promise of matching performance.
