Prevention of acne scarring. As the name implies, acne scarring is caused by acne, and its prevention lies in the active treatment of acne. In clinical practice, we often encounter people who think that acne is not a disease and that they will get better without worrying about it. Unbeknownst to us, acne can develop into nodules, cysts, scars, and in severe cases, disfigurement, which seriously affects people’s physical and mental health. Therefore, to prevent acne scars, we must start with acne and go to the dermatology or cosmetic dermatology department in a timely manner.
Acne scarring is a common and difficult to treat skin disease. Acne scars are mainly divided into atrophic acne scars, hyperplastic acne scars and keloid scars.
Atrophic acne scars are commonly treated clinically: first, surgical excision, including “punching” techniques.
The second is a variety of filler techniques, including autologous and autologous. Autologous ones such as autologous collagen, dermis and fat grafting. In recent years, autologous platelet-rich plasma (PRP) technology is widely used, with a wide range of sources and simple operation, and may replace other filler materials in the future. Non-autologous fillers, such as human collagen and hyaluronic acid, are expensive and have a short maintenance time.
Thirdly, various epidermal reconstructive procedures: inducing collagen formation to enable collagen reconstruction, both injurious and non-invasive. Such as microdermabrasion, grinding, chemical peeling (if acid peeling), CO2 laser epidermal reconstruction, plasma epidermal reconstruction, fractional laser epidermal reconstruction, non-exfoliative epidermal reconstruction, toner laser (black face doll), photodynamic therapy and skin microneedling. Currently, fractional laser and plasma epidermal reconstruction are more widely used.
Fourthly, for areas with obvious muscle activity, excessive muscle activity can make atrophic scarring more obvious, and botulinum toxin injection can make scarring less obvious.
Treatment for proliferative keloid and scars: 1, surgery, 2, local closure, glucocorticoids and cytotoxic drugs such as 5-fluorouracil, bleomycin and mitomycin.
3, Topical drugs such as imiquimod, basic fibroblast growth factor, etc.
4.Silicone gel.
5.Local compression.
6.Radiotherapy, such as electron beam, etc.
7.Vascular laser.
Mostly, a combination of treatment methods are used.
In addition, sometimes the scars look obvious due to the obvious color. If it is post-inflammatory hyperpigmentation, some depigmentation drugs are available. If it is red, pulsed dye laser treatment (585nm) is available. If the pigment is hypopigmented, melanocyte transplantation is required.
In conclusion, acne scarring is as difficult to treat as other scarring and sometimes requires multiple treatments. Prior to treatment, full communication is needed to understand the advantages and disadvantages of each treatment, and then work together to develop a feasible treatment plan that is acceptable to everyone.
