Stretch marks are caused by a permanent contraction of the fibroblasts (a type of connective tissue), which then produces dysfunctional collagen and elastin. After much research, Talika has isolated D-STRETCH®, an effective ingredient that aims to reverse the process causing the appearance of stretch marks, and has incorporated it into a concentrated anti-stretch mark formula. This is the main key ingredient of Zero Stretch Mark. Zero Stretch Mark targets recent and established stretch marks, irrespective of their location (thighs, hips, buttocks, stomach, breast, arms, etc.).
