“An innovative anti-ageing treatment serum formulated with powerful peptides to help reduce expression lines and wrinkles, while antioxidants work to defend against free radicals responsible for premature ageing.”
This product contains acetyl octapeptide-3, tripeptide-1. These ingredients 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.
Anti-oxidationNot advertised by the brand · 5 ingredients credited for this claimStrong support
This product contains antioxidants (dimethylmethoxy chromanol) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).

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:
glycerin, sodium pca.
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: ribes nigrum seed oil, cyclopentasiloxane.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl octapeptide-3, tripeptide-1

Product summary
"Dr. LeWinns - Line Smoothing Complex Triple Action Defence" has a good moisturizing formula. This moisturizer uses a good combo of humectants and emollients. These both types of ingredients are essentials for improving the skin hydration and keeping the skin barrier healthy. Humectants in this product (acetyl octapeptide-3, glycerin, sodium pca, hydrolyzed soy protein and hydrolyzed wheat protein) 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 (tripeptide-1, ribes nigrum seed oil, cyclopentasiloxane and caprylyl glycol) 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 (tripeptide-1 0.25% - 0.45% and acetyl octapeptide-3 0.20% - 0.40%). 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.
Irritation risk
This moisturizer contains a bunch of common irritants, including ingredients that do not provide any known benefit for the skin. It might not be the best choice if your skin is sensitive.
