“What Else You Need to Know: This powerhouse formula softens and hydrates, soothing dry, flaky lips and visibly reducing the look of fine lines.”
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:
polyglycerin-3, sodium hyaluronate.
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-agingPalmitoyl tripeptide-1, Butyrospermum parkii butter + 1 moreMay help
“What Else You Need to Know: This powerhouse formula softens and hydrates, soothing dry, flaky lips and visibly reducing the look of fine lines.”
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
"Kosas - Plump Juicy Lip Booster Lip Treatment" is a well-rounded moisturizing product. 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 (polyglycerin-3 and sodium hyaluronate) 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 (palmitoyl tripeptide-1, helianthus annuus seed wax, jojoba esters, bis-diglyceryl polyacyladipate-2 and butyrospermum parkii butter) 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
- We like that this moisturizer contains peptides (palmitoyl tripeptide-1 0.40% - 0.90%). There are many different kind of peptides and they are naturally present in our skin. They all are a combination of amino-acids. Some of them work as natural anti-biotics, promote wound-healing and production of collagen. The science is still not settled on how effective peptides in skincare are, but it is very likely that they have a benefit. Peptides might help restore the skin barrier and fight the signs of aging. At the very least, peptides work as humectants: they attract water to the upper layer of the skin and improve its hydration.
