Puberty is the high incidence of acne. Many serious friends have acne not only on their faces, but also on their backs and chests, and they are troubled by acne every day. Red and blue light is a very popular method to treat acne. Many people still don't understand this new method of acne, so how about red and blue light to treat acne? Experts recommend that red and blue light photodynamic therapy instrument is a good choice for acne treatment. Its principle is to choose a cold light, which does not produce high fever and does not burn the skin. Its light is converted into energy in cells, which stimulates fiber cells to produce collagen. It can bring unexpected results to the repair of aging skin, acne skin, spotted skin, wrinkled skin, allergic symptoms and sunburned skin. Red and blue light acne removal is one of the safest and most effective instruments for treating acne and rejuvenation. Red light has the characteristics of high purity, strong light source and uniform energy density, and has remarkable effects in skin care and health care treatment, so it is called bioactive light. Red light can improve cell activity, promote cell metabolism, and make skin secrete collagen and fibrous tissue to fill itself. Accelerate blood circulation, increase skin elasticity, improve skin chlorosis and dullness, so as to achieve anti-aging, anti-oxidation and repair effects, which are all effects that traditional skin care cannot achieve. In addition, in terms of skin cleaning and care, female friends who are prone to acne should also pay great attention to methods. For patients who only suffer from blackhead acne and whitehead acne, the condition is relatively mild. Only after facial cleaning and disinfection can facial acne be cleaned up, and it can be cured with traditional Chinese medicine mask.
