The sunken pits on the face are considered to be related to post-acne atrophic scarring and localized fat atrophy caused by trauma, and the treatment should be based on the causes of which, such as laser and local injections should be chosen.
1. Laser: For the localized sunken pits on the face left behind in the late stages of acne and pimples, lasers, such as intense pulsed light and fractional lasers, can be used to stimulate the proliferation of local collagen and other substances, so as to achieve the effect of filling the localized sunken pits.
2. Local injection: for patients with local fat atrophy caused by trauma, hyaluronic acid and autologous fat can be injected into local depressions. Hyaluronic acid belongs to a kind of hyaluronic acid, which can play a role of hydration and moisturizing and fill the role of local filling, but it can’t achieve long-term maintenance; local injection of autologous fat will last a little bit longer, and won’t have any rejection reaction.
For patients with sunken pits on the face, it is recommended that they go to a regular medical institution and choose the appropriate way of active treatment under the guidance of the doctor.
