Bottom line
If you want a light moisturizer with added peptides, this is a practical Budget option. If clinical wrinkle outcomes drive your purchase, compare a more directly tested treatment.
If you want a lightweight daily cream with peptide support rather than a dedicated wrinkle treatment, The INKEY List Peptide Moisturizer gives you a Budget formula with glycerin, betaine, shea butter, Acetyl Hexapeptide-37, and Pentapeptide-48.
The moisturizing base is the most dependable part of the formula. The two peptide technologies add useful differentiation, but the current public page still does not publish finished-product clinical methodology for a defined wrinkle-reduction endpoint.

What it claims
The INKEY List markets Peptide Moisturizer as a lightweight, fast-absorbing cream with a 2% Royal Epigen P5 blend and a 1% Hydrating Peptide Solution. The brand identifies the actual peptide ingredients as pentapeptide-48 and acetyl hexapeptide-37, respectively, and confirms vegan, cruelty-free and non-comedogenic positioning.[1]
The stated percentages describe branded ingredient solutions, not the concentration of each pure peptide. The public page does not provide a detailed randomized trial proving a defined wrinkle reduction from this cream.
Claims vs. formula
Glycerin and betaine support water binding, while caprylic/capric triglyceride, alkyl benzoate, cetearyl alcohol and shea butter help soften skin. Established research on glycerol explains the hydration mechanism, though it did not test this product.[2]
The two peptides are present, but the public blend percentages cannot establish their actual separate doses or clinical contributions. The formula supports everyday moisturizing more directly than it establishes biological age reversal or an effect comparable to dedicated wrinkle treatments.
Ingredients that matter
Glycerin and betaine contribute water-binding support; peptides add a secondary appearance-related feature. The fatty and emollient base affects actual comfort more than the marketing names of the peptide blends.
The formula contains benzyl alcohol as a preservative-related component, not evidence of a perfumed cream.
Glycerin
If your skin feels dry or tight, glycerin helps your skin hold moisture. You don't need a high percentage or a separate serum when your moisturizer already works well.
Read the IngredientBriefBetaine
Betaine is a well-established humectant and skin-conditioning ingredient that adds lightweight moisture support. It is useful but replaceable, and it should not be confused with similarly named betaine surfactants or…
Read the IngredientBriefShea Butter
Shea butter is a well-established emollient and occlusive used to soften dry-feeling skin and add richness to moisturizers. Its value depends on the complete formula, not the ingredient name alone.
Read the IngredientBriefPeptides
If fine lines are your concern, some peptide formulas have human evidence. Check the named peptide and finished-product testing; you don't need a separate serum when your routine already meets…
Read the IngredientBriefWhat to expect in the short term
You get a lightweight, non-sticky cream that layers easily under sunscreen or makeup and gives you straightforward moisture and softness.
What to expect over time
The most dependable ongoing benefits are maintained hydration and barrier comfort. The peptide system adds plausible support for smoother, more even-looking skin, but this should not be treated as a treatment-level wrinkle claim.
Who it fits
This makes the most sense if your skin is dry, normal, combination, oily, or sensitive and you want a lighter cream with peptide support.
Compare before you buy
Choose Peptide Moisturizer when you want a lightweight daily cream with current Non-Comedogenic, Vegan, and Cruelty-Free support plus a clearly identified dual-peptide system.
Choose Bio-Active Ceramide Moisturizer when richer barrier support and a stronger finished-product evidence package matter more.
Final Assessment
The INKEY List Peptide Moisturizer provides sensible Budget value for a moisturizing cream with two clearly identified peptide technologies. Choose it for routine comfort and formulation convenience, not because the 2% and 1% solution figures prove finished-product wrinkle correction.
