“It contains seven times more lip boosting actives—hyaluronic acid, peptides and plumping botanicals—for full, cushiony-looking lips without the sting.”
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-aging3 ingredients credited for this claimModerate support
“, Plump Oleactif Visibly strengthens and plumps. , Peptides Visibly firm and smooth.”
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 Buttery Treatment" is effective for: Moisturizing
This lip product could be helpful for: Anti-aging, but its actives are not the most effective or are not well-studied.
Ingredient callouts
- This moisturizer also contains Peptides (palmitoyl tripeptide-1 0.40% - 0.90%). Peptides are a very big group of ingredients. They all consist of a different combination of aminoacids. Our skin produces Peptides naturally. Some of them work as natural antibiotics, 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 they are helpful. Peptides 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.
