MoisturizingPalmitoyl tripeptide-38, Carthamus tinctorius seed oil + 8 moreStrong evidence
“A hydrating lip treatment that minimizes the appearance of lip lines.”
This product can help soften the skin and reduce its moisture loss with emollients and occlusives: butyrospermum parkii butter, helianthus annuus seed oil.
Keep in mind that this product does not contain effective ingredients to attract water to the upper layer of the skin. This is why an additional product with humectants like glycerin or hyaluronic acid can be helpful (apply it before this product for the best results).
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: palmitoyl tripeptide-38
Anti-agingPalmitoyl tripeptide-38, Butyrospermum parkii butterModerate evidence
“A hydrating lip treatment that minimizes the appearance of lip lines.”
This product contains palmitoyl tripeptide-38. This ingredient might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.

Product summary
Based on the ingredient list, "PCA SKIN - Peptide Lip Therapy" can work well for skin moisturization. As we expect from a proper moisturizer, the formula includes a combo of effective humectants and emollients. These are the two different types of ingredients that are essential for improving the skin hydration and supporting a healthy skin barrier. Humectants in this product (aloe barbadensis leaf extract) help to increase the water content in the upper layer of the skin. (These ingredients do so by "capturing" water molecules from the outside air or from within the deeper layers of the skin). Emollients in this formulation (carthamus tinctorius seed oil, butyrospermum parkii butter, helianthus annuus seed oil, ricinus communis seed oil and squalane) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.
Ingredient callouts
- This moistruizer also contains peptides (palmitoyl tripeptide-38 0.35% - 0.80%). Peptides is a very big group of ingredients. They all consist of a different combination of amino-acids. Our skin produces peptides naturally. Some of them work as natural anti-biotics, promote wound-healing and production of collagen. The scientists are still studying how effective the topical application of peptides is, but it is very likely that peptides in skincare are helpful. They might be able to support skin barrier restoration and even have an anti-aging benefit. At the very least, they certainly help attract water to the skin and support the hydration in this way.
