A stretch mark is a type of scar that develops when our skin stretches or shrinks quickly. The abrupt change causes the collagen and elastin, which support our skin, to rupture. As the skin heals, stretch marks may appear. Not everyone develops these narrow bands on their skin. As explained by the American Association of Dermatology.
Collagen fiber break up into collagen bundle and collagen fibers need to be re-aligned.
You can greatly lessen their appearance by using:
Hyaluronic acid is also found to be effective in stretch marks as it increases collagen production. It increase tensile resistance to mechanical forces
Cynarin - Trofolastin (Centella asiatica). It stimulates fibroblasts and antagonist to glucocorticoid effect
Silicio Organico – silicone increases skin hydration.
Vitamin C - ascorbic acid. It increase tissue collagen I levels through fibroblastic stimulation.
Microneedling can help re-align collagen fibers by breaking up the stringy fibers that make up scar tissue.
Cosmetic type micro-needling, is your basic dermaroller with a needle length of only 0.13 mm (130 μm). Available on Dermetech.
CIT: Collagen Induction Therapy, Medical type has a needle length of 0.5 mm (500 μm) and helps in collagen induction and skin remodelling.
Micronneedling 1M has a needle length of 1 mm (1000 μm). This creates deeper microchannels on the whole epidermis and dermis and at the same time destroys scar collagen bundles.
