Acne Pit Terminator” Dot Matrix Laser: Put a poke on the face, and the acne pit will be flat?

          Acne three-piece set: acne, acne marks, acne pits. Among them, acne is very annoying, and acne marks are difficult to deal with. More desperate than them are the acne pits on the face. How to fill these “youth pits”?


          First of all, let’s review the following knowledge points: acne scars, there are mainly two types of atrophic scars (concave) and hypertrophic scars (protrusion). The more common atrophic scars are actually what we often call acne pits, which can be divided into three types: ice pick type, van type, and rolling type.


          Common treatments for acne pits include: chemical peels, fractional lasers, subcutaneous separations, microdermabrasion, fillers, and more. Because scars often come in different types, a combination treatment is more effective than a single treatment. (Don’t ask why there are no skin care products recommended, skin care products really have little effect on acne pits)


          Among them, the treatment method of fractional laser is called “acne pit terminator” by some people. Not as painful as laser grinding, but works well. Today, follow us into the world of fractional laser to learn about it~

          What is fractional laser?




          Fractional laser is based on the focal photothermal effect, using some special technical means (scanning hand tools or lenses, etc.), so that the laser emits many tiny beams of the same diameter and size, and the beam acts on the skin to form a large number of uniformly sized and arranged micro-heats. The damaged area, while the tissue surrounding the beam is not damaged.


          This is a thermal injury and post-injury repair process that promotes dermal tissue regeneration, new collagen fiber synthesis, and collagen remodeling to improve acne scars.




          Fractional laser is mainly suitable for the treatment of superficial scars, atrophic scars, large pores, acne pits and acne marks, and it also has a certain effect on improving stretch marks.




          The reference price is about 1500-6500 RMB once, and the price will vary depending on the region, doctor, equipment, and effect area. Generally, fractional laser treatment does not need to select a specific season, and can be used in spring, summer, autumn and winter.




          According to the strength of laser absorption of water and whether it has gasification effect on skin tissue, it can be divided into ablation (gasification type) fractional laser and non-ablative (non-gasification) fractional laser.


          When a laser beam irradiates the skin to form a columnar area of thermal degeneration, it is called a non-ablative fractional laser. If a true aperture is finally formed, it is called ablation fractional laser.


          Ablation Fractional Laser

          The exfoliation fractional lasers mainly include carbon dioxide fractional lasers (10600 nm) and decoy fractional lasers (2940 nm).


          Among them, the thermal effect of carbon dioxide fractional laser is the strongest, and the effect of treating acne pits is better. It operates like a “chessboard” on the face, similar to a point-and-shoot camera/printer.


          According to the handsome guy who went to the clinic to experience the carbon dioxide fractional laser, the part of the face that was hit by the deeper (2400nm) will turn brown, while the part hit by the low energy (1800nm) will first turn white and then red.


          The advantages of ablative fractional laser are that the effect is significant and the duration is long. You can feel the obvious improvement of the acne pits in a single time, but you still need to insist on multiple treatments to have better results. One course of treatment is about 4-5 times. , every 1-2 months.


          But there are many adverse reactions, such as erythema, edema, crusting, desquamation and so on. Epidermal regeneration generally recovers within 48 days, usually within 5-7 days, but side effects such as abnormal pigmentation, scarring, herpes simplex virus reactivation, and itching may also occur.


          Non-ablative fractional laser


          Er: glass(1550 nm、1540 nm)、Nd: YAG(1064 nm、1440 nm、1320 nm)、Er:Fiber(1410 nm),(694nm)、(1927 nm).


          Non-ablative lattice lasers mainly include Er: glass (1550 nm, 1540 nm), Nd: YAG (1064 nm, 1440 nm, 1320 nm), Er: fiber laser (1410 nm), ruby laser (694 nm), thulium Fiber Laser (1927 nm).


          Non-ablative fractional lasers mainly include Er: glass (1550 nm, 1540 nm), Nd: YAG (1064 nm, 1440 nm, 1320 nm), Er: Fiber laser (1410 nm), and ruby laser (694 nm), thulium Fiber Laser (1927 nm).Non-ablative lattice lasers mainly include Er: glass (1550 nm, 1540 nm), Nd: YAG (1064 nm, 1440 nm, 1320 nm), Er: fiber laser (1410 nm), ruby laser (694 nm), thulium Fiber Laser (1927 nm).


          Several studies have investigated the effects of non-ablative fractional lasers on different types of acne scars. The results showed that its clinical treatment effect on box-type scars was the best among the three types, followed by roller-type scars.


          By cooling the epidermis, the non-ablative laser can heat the dermis without damaging the epidermis. At the same time, the incidence of adverse reactions can be reduced to a certain extent. It is more gentle and safe, with less trauma. The regeneration of the epidermis can be completed within 24 hours. . The recovery period is also shorter (usually 1-3 days), and you can go out and meet people after resting at home for a while.


          However, the curative effect of non-ablation fractional laser will be relatively insignificant, and generally requires more than 5 to 8 treatments, with an interval of 3 to 4 weeks. It was observed that the efficacy after 3 months of treatment was more significant than after 1 month of treatment.

          Taboo crowd & uncomfortable crowd


          Taboo crowd


          People with an active infection (mainly herpes virus infection), people who have recently tanned (especially within 4 weeks), people with active skin inflammation, people with symptoms of skin barrier damage (such as increased skin sensitivity) , Patients with suspicious malignant lesions in the treatment area, patients with organic lesions of vital organs, pregnant women and lactating women.


          Unwell people


          People with untreated acne (would you be overwhelmed if you developed acne after treatment?). People with a history of poor wound repair, keloid, and hyperpigmentation after inflammation. And people who have undergone other medical and cosmetic treatments at the same site (such as other types of lasers, chemical skin changes, etc.).


          Postoperative nursing precautions


          Postoperative adverse effects of fractional laser include delayed erythema, hyperpigmentation, and increased skin sensitivity. Postoperative care is based on the principles of promoting healing, sun protection, and moisturizing, with special attention to the repair of skin barrier function.


          Eschar remains after ablative laser exposure. Don’t pick it out yourself, just wait for it to fall off naturally.


          Try to avoid sun exposure and apply sunscreen strictly, otherwise it will leave pigmentation and affect the appearance, and you have to spend money to remedy it.


          Wet compresses with normal saline can be used, followed by mild moisturizing products, generally not covered with dressings.


          Finally, I want to say that the best way to deal with acne pits is actually prevention. When acne germinates, “kill” it in the cradle, so as not to delay the formation of acne pits, which is difficult to treat and burns money.
