“Hyaluronic Acid, Peptides, Evening Primrose Oil and other botanicals work to hydrate, visibly plump, and protect the lips.”
This product can help improve hydration of the skin with the two types of ingredients.
The first type is called “humectants”:
these ingredients help attract water.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from
within deeper layers of the skin. The following ingredients in this product do the job:
sodium hyaluronate, caprylyl glycol.
This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: bis-diglyceryl polyacyladipate-2, butyrospermum parkii butter.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: palmitoyl tripeptide-1
Anti-agingSide benefit · Palmitoyl tripeptide-1, Butyrospermum parkii butter + 2 moreMay help
This product contains palmitoyl tripeptide-1. 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, "Kosas - Wet Lip Oil Plumping Treatment Gloss" 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. Sodium hyaluronate and caprylyl glycol in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Palmitoyl tripeptide-1, helianthus annuus extract, oenothera biennis oil, persea gratissima oil and bis-diglyceryl polyacyladipate-2 in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.
Ingredient callouts
- This moistruizer also contains peptides (palmitoyl tripeptide-1 0.40% - 0.90%). 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.
