Skinceuticals Body Tightening Concentrate- reviewed and recommended
Body Tightening Concentrate contains 2.5% tripeptide, aka tetradecyl aminobutyroylvalylaminobutyric urea trifluoroacetate, also found in Osmotics Necollete ($63). The tripeptide, sometimes marketed under the simpler name of Syn-Hycan, is aimed at lifting sagging skin. It stimulates hyaluronic acid and glycosaminoglycans (GAGs) expression to volumize skin. GAGs are essential molecules that can bind up to 1,000 times their weight in water.
The efficacy of the glycerin-based aqueous solution was tested in a double-blind parallel group study. An emulsion containing either 2.5% of the tripeptide solution or none, was applied twice daily to the face and forearms of 41 female volunteers. After 56 days, The emulsion containing 2.5% bio active tripeptide solution was found to significantly increase skin tonicity and firmness when compared to untreated and placebo-treated skin.
I also like the inclusion of menthyl lactate, also found in Arcona Peptide Hydrating Complex ($75 in the shop), in this formulation. Menthyl lactate is an ester of lactic acid, which is a an excellent humectant and extremely gentle exfoliant. It provides a mild cooling sensation, which is derived from menthol, a potential irritant. However, menthyl lactate is generally known to cause less irritation than menthol, which is why it is preferable. Overall, menthyl lactate hydrates and smooths with an added cooling sensation that makes skin feel refreshed.
Skinceuticals does not formulate for purists and there are some ingredients that I could live without. However, Skinceuticals does seem to be making an effort to be somewhat “greener” as this formulation is free of parabens and fragrance. I noted the inclusion of pentaerythrityl tetraethylhexanoate, an emollient, toward the top of the ingredients list and while there isn’t much known about it, no studies have been found that indicate it has any adverse side effects or safety measures regarding the use of it. Further, Good Guide notes that it’s not suspected or recognized for toxic health effects.
Per Skinceuticals, Body Tightening Concentrate provides complementary lifting, firming, and tightening action and smooths skin’s texture. The lightweight, gel-like lotion applies smoothly and easily absorbs, leaving skin feeling exceptionally smooth. The combination of ingredients do make your skin feel tighter without drying it out. It’s not a miracle worker and anyone looking for instant gratification should look elsewhere. However, the luxury lotion will certainly smooth skin with regular use while providing mild firming action. Although the tightening sensation is short-lived, it’s certainly a nice effect to get from a body lotion.
