Summer is here, and for many students who suffer from acne, this is a good time to “fix it” and get their face back to flat. Acne is known as acne in medical terms. Some people’s “pimples” are in the red and inflamed stage, while others have formed dark red or dark brown acne marks, and others have developed sunken pockmarks. These problems can be solved clinically, but at the same time, the patient also needs to cooperate with the diet adjustment. The first step in the battle against acne is to adjust the diet: acne occurs in areas of the face with high oil secretion, often on the cheeks, nose, forehead and jaw area, and also on the chest and back. It is common in adolescence, but there are also adults who continue to have acne even after puberty. The causes of acne are complex and include genetic and environmental triggers. Some students experience significant relief from acne after exams are over, as a result of the elimination of the triggers of academic stress. For those with mild to moderate acne, a regular lifestyle and diet are half the battle, along with other treatment options. The best time for the body’s organs to recuperate is from 11:00 p.m. to 5:00 p.m. The best time to ensure that you sleep and take care of your skin at the same time. You should eat more fresh, light foods and less high-sugar, high-fat, high-calorie foods, especially deeply processed foods. Blue light helps kill acne bacteria: There are many ways to treat acne. Traditional treatments include topical applications or oral antibiotics, but these methods are not as effective as they could be for stubborn lesions and most have significant side effects. In recent years, the research and application of photothermal technology has provided a completely new approach to acne treatment. Currently, blue light technology is the most convenient, fastest, safest, and very effective means of treating acne. The presence of Propionibacterium acnes in acne skin and the metabolism of Propionibacterium acnes produce endogenous porphyrins, which are activated by the absorption of blue light, leading to a phototoxic effect that kills bacteria and produces an anti-inflammatory effect. In addition to the anti-inflammatory effect, there is also a bioregulatory effect, which is manifested by balancing oil secretion, which can play a more important role in the post-treatment response. Blue light therapy can inhibit sebaceous gland secretion to varying degrees, reduce the number of sexual lesions, inhibit recurrent lesions and promote tissue repair, but is not effective for nodular cystic lesions. Blue light therapy is given 1-2 times a week, with 6-8 treatments as a course of treatment. Generally, 1-2 treatments are effective, and less frequent treatments are needed for mild lesions. Acne scar removal with microbeam laser: Acne can also cause unsightly and difficult to eliminate after-effects – acne marks and pits, but there are now new technologies that can solve these problems. Microbeam laser is a new type of laser technology following traditional laser, photon and radio frequency technologies. It uses focal photothermal action, which applies certain wavelengths of laser light in the form of microbeams to the skin surface, thus creating many micro treatment areas, stimulating the proliferation of dermal collagen fibers, improving the texture and skin tone, and can be used for scar treatment including post-acne scarring, as well as for skin rejuvenation, facial wrinkle removal, and It can also be used for skin rejuvenation, facial wrinkle removal, treatment of superficial skin lesions, etc. The commonly used microbeam lasers are image beam lasers and fractional lasers, which are suitable for different conditions because they do not have the same level of tissue penetration. If only acne marks are present and the skin is flat and smooth, photorejuvenation or image-beam laser treatment can be used to significantly improve the pigmentation left after an acne flare-up. Photorejuvenation does not require vacation and recovery period, but the effect is relatively slow; while with beam laser treatment, the skin will be slightly decabbed and the recovery period is about 3-5 days. If the acne attack is severe and leaves depressed scarring (acne pits), the treatment will be relatively complicated and usually requires fractional laser treatment or radiofrequency plasma treatment, which will result in significant skin debridement with a recovery period of about 7-10 days and a number of treatments ranging from 3 to 6 times.
