Acne, during its onset and treatment period, due to non-standard treatments or severe cases, coupled with some patients liking to pick or squeeze them, might lead to hypertrophic scarring later. Once hypertrophic scars form, they are not easy to treat, especially if they are very prominent, they generally cannot be completely cured. If the symptoms are mild, fractional laser treatment can be used, but the ultimate repair effectiveness is uncertain. If the prominence is especially noticeable, one can go to a dermatology department in a regular hospital for localized drug blockade treatment, but this only improves the symptoms and cannot eradicate the condition completely. Therefore, it is essential to follow standard treatment protocols during the onset of acne to prevent the formation of hypertrophic scars.
