This product can help soften the skin and reduce its moisture loss with emollients and occlusives: cocos nucifera oil, diisostearyl malate.

Keep in mind that this product does not contain effective ingredients to attract water to the upper layer of the skin. This is why an additional product with humectants like glycerin or hyaluronic acid can be helpful (apply it before this product for the best results).

Hydroxymethoxyphenyl propylmethylmethoxybenzofuranIt is a derivative of isoeugenol, an aromatic compound in clove essential oil. It is sold to cosmetic companies under the name Sym3D. The ingredient's manufacturer claims that it is able to plump lips and have an anti-aging effect. The evidence of effectiveness, however, is weak. The lab tests with skin models (not with real people) show that it, in theory, it can increase the number and size of fat cells underneath the skin and can work as an anti-oxidant. To impact the fat cells, the ingredient, however, needs to penetrate deep through the skin - and it is unlikely that it can do this. A clinical test with 44 female volunteers conducted by the manufacturer showed that twice daily application of this ingredient in 0.25% concentration on lips increased their volume by 6% in 28 days. It is unclear where the effect is coming from. It is possible that this visible effect appears because of the skin irritationHigh~0.3–0.75%est.
