“, 3% Bar Pull Hydrates and provides long-term benefits.”
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, butylene 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: palmitoyl tetrapeptide-7, caprylyl glycol.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: dipeptide-2, palmitoyl tetrapeptide-7

“Clinical Results Based on an 8-hour clinically measured study on 14 women, ranging in age from 32 to 65 , 100% of subjects showed immediate skin-firming results Based on a 4-week clinical and consumer perception study on 31 women, ranging in age from 38 to 70 , 100% agreed product blended well with skin tone and absorbed quickly , 93% agreed skin had less visible pores”
This product contains dipeptide-2, palmitoyl tetrapeptide-7. 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.

Ingredient callouts
- This product also contains Vitamin C (Ascorbic Acid). It can be an effective active for anti-aging and evening out the skin tone, but in this product it is used for stabilizing other ingredients in the formulation. In this concentration (0.20% - 0.40%) it cannot have a noticeable benefit for the skin.
- Peptides (palmitoyl tetrapeptide-7 0.30% - 0.60% and dipeptide-2 0.30% - 0.60%). There are many different kind of Peptides and they are naturally present in our skin. They all are a combination of aminoacids. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The science is still not settled on how effective Peptides are in skincare, but it is very likely that they have a benefit. They 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.
- Humectants (glycerin 4.70% - 5.80%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
