The inflammatory response caused by acne causestissue destruction, atrophy, and scar formation. After the space left by the tissue destruction is damaged, pits of different shapes and shades are formed, which is what we often call acne pits.
The atrophy of the epidermis, dermis, and subcutaneous fat further worsens theacne pits, and also makes the entire face lookthin, sagging, and old. The involvement of scar tissue can cause the facial muscles to exercise unnaturally. In addition, the skin’s ability to regenerate after being damaged deteriorates, and collagen and elastic fibers are damaged. It also makes the skin inelastic and wrinkles appear early.
Therefore, for people with acne pits, I generally recommend taking measures to eliminate them as soonas possible. On the one hand, skin projects often involve repair. Theyounger you are, the stronger your own repair ability, and the better the effect of the project; On the other hand, acne pits can causewrinkles to appear in advance, causing the skin to age further.
How dot matrix laser treats acne pits
The principle of dot matrix laser scar treatment is to instantly solidify and carbonize the scar tissue in the treatment area, form a thermal exfoliation area, stimulate various cytokines, limit excessive inflammatory response, quickly start tissue regeneration, repair and cover the wound, effectively shorten the wound healing time, prevent scar hyperplasia, and regulate extracellularThe composition of the matrix and the arrangement of collagen promote the relaxation and softening of the scar, making the scar smoother and more flexible.
To put it directly, it is to carbonize the skin around the acne pit through high temperature, and stimulate the tissue regeneration of this part, thereby flattening the acne pit.
Since the dot matrix laser can well break through the atrophied tissue around the acne pit and stimulate collagen fiber hyperplasia, the therapeutic effect is very good for the treatment of acne pit.
Dot matrix lasers can be divided into two types of exfoliating dot matrix lasers and non-exfoliating dot matrix lasers according to the wavelength of the laser.
Exfoliating dot matrix laser
The main use iscarbon dioxide dot matrix laser(10600nm),erbium laser dot matrix laser(2940nm)
What everyone usually sees that willpeel off after itis done is the exfoliating dot matrix laser.
Advantages:The surface layer exfoliates strongly, which has a strong ability to regenerate collagen, and the therapeutic effect is obvious.
Disadvantages: The penetration depth is shallow, because the epidermis is heavily damaged,and the probability of pigmentation is greater than that of non-exfoliation.
Non-exfoliating dot matrix laser
Mainly use 1540nm, 1440nm
After the non-exfoliating dot matrix laser is finished, there will be basically no peeling.
Advantages:Short recovery period after treatment, fewer side effects, less，pain,light postoperative inflammatory response, and reduced probability of pigmentation.
