Drunk Elephant Protini Review: Do Nine Peptides Justify $72?
A pH 4.0 gel cream with nine signal peptides, no fragrance and no silicones. The brand's study numbers are real but small, so we weigh what 31 people can and cannot prove about a $72 moisturizer.
Our verdict
Protini is a pleasant, fragrance-free gel cream that hydrates well and feels light, but the firming claim rests on a 31-person, 8-week brand study that cannot separate peptides from any good moisturizer. At $72 for 50 ml it is a luxury texture purchase, not a proven anti-aging one. Cheaper peptide products cover the same ground.
Best forNormal to dry skin that wants a light, scent-free gel cream
What we liked
- Light gel-cream texture that layers under serums and sunscreen
- No fragrance, essential oils, silicones or solvent alcohols
- Refill pouch and a 100 ml size lower the cost per ml
- Formulated at pH 4.0, which suits peptide stability
What held it back
- $1.44 per ml in the standard size is steep for a moisturizer
- Firming evidence is a small brand-run study with no control group stated
- Some acne-prone users report breakouts
- Mild hydration only, so very dry skin needs a richer cream on top
Protini asks for $72 and promises firmer skin. After going through everything Drunk Elephant publishes about it and the independent write-ups we could find, our answer is split. As a moisturizer it is lovely. As a firming treatment it is unproven, and a plain moisturizer at a quarter of the price would give you most of the same results.
We did not run a clinical trial. This review weighs the maker's formula and study claims against an independent ingredient analysis and the complaints that recur in buyer reviews.
What $72 buys
The standard jar holds 50 ml, which works out to $1.44 per ml. Drunk Elephant also sells a 15 ml size, a 100 ml size it calls the best value, and a 50 ml refill pouch, so the cost drops if you commit. The refill is the more sensible way to buy it: the glass jar is reusable.
The formula is built around three headline ingredients: nine signal peptides, pygmy waterlily stem cell extract and a soybean folic acid ferment extract. It leaves out essential oils, silicones, fragrance, dyes and solvent alcohols, and it is set at pH 4.0. That last number matters more than it sounds. Peptides are fragile in strongly acidic or alkaline products, and a mildly acidic base is where they are supposed to behave.
