The derma pen treatment is the ideal measure for face, neck, décolleté and hands for: sun-damaged skin, wrinkles and wrinkles, loss of elasticity, acne scars, kelloid scars, pigment disorders, stretch and stretch marks. ? Incregly used anti-ageing treatments of the skin that improve skin thickness and target the reproduction of elastic fibres, especially collagen. Micro-needling is considered a revolution among these anti-ageing methods, because it very effectively tightens the skin and hardly strains, is not painful and almost no downtime. ? To counteract this premature skin ageing, a number of procedures have already been developed. Dermabrasion, scrubs and laser treatments all wear off the top layer of skin to achieve rejuvenation. But these treatments make the skin thinner. The thinner the skin, the more sensitive it becomes to our environment, e.g. the sun. You get stained or parchment-like skin. ? Your skin is constantly damaged by external influences, such as UV radiation, soaps, cosmetics, smoking and stress. Now in winter time, the cold also dries out your skin. The consequences are wrinkles and wrinkles, pigmentation disorders and a coarse-pored relief - the signs of skin ageing.
