First, the classification of acne pits
The essence of pockmarks is concave scars or atrophic scars, which are mainly divided into three categories according to the different shapes of depressions:
1. Roller type: it looks like a plate on the skin, with shallow pits, large area and inconspicuous edges. This kind of pockmark is the best treatment.
2. Horse model: On the epidermis, the bottom area is smaller than the opening, the edge is obvious, the depth is moderate, and it looks like bowls of different shapes. This kind of pockmark is the most common, and the treatment depends on the depth.
3. Ice cone type: This is the big BOSS in the pockmark, with a small opening and a deep depth, and the bottom almost shrinks into a point, which looks like it was cut by an ice cone. Because this kind of pit is deep, it will be more difficult to repair. Cover your wallet and face it seriously. )
Second, the treatment of acne pits
The formation of pockmarks is a manifestation of dermal damage. The epidermis of the human body has a strong self-healing ability, but the damage of the dermis can't heal itself (the human body is so magical). Therefore, the basic idea of repairing acne pits is: first destroy, then repair.
Simply put, it is to destroy the tissue in the acne pit first, use some drugs to promote the repair of dermal tissue, and then use the self-repair ability of epidermis to achieve the purpose of calming the acne pit.
Don't the babies understand? ! (Innocent face)
For example, I found a stone in the dough when steaming steamed bread. What about swelling? Pull it out! Yes! Using the self-repairing function of dough, steamed bread is as perfect as ever. (Bian Xiao's brain hole is limited, and this metaphor is not appropriate. Smart babies fill their brains by themselves. )
(So when you see a certain kind of skin care products claiming that you can fill the acne pit by smearing and repairing, you can basically take a detour. )
Third, laser treatment of acne pits (dry goods must be seen)
Carbon dioxide lattice laser (carbon dioxide lattice)
It is recognized as the most effective laser to treat acne pits on the market at present. It can penetrate deep into dermal tissue to produce great stimulation, and at the same time, it can cause epidermis to vaporize and fall off.
Wavelength: 10600
Recovery period: about 2-3 days, 5- 14 days.
Cost: 3000 -6000 yuan/time (quotations vary from place to place)
Course of treatment: This varies from person to person. Some people only need 1-2 times, and some people do it 5-6 times or more.
Risk: It may cause pigmentation and adverse reactions.
Applicable objects: roller-type acne pits, shallow horse-type acne pits.
Bait laser
Short wave length, high absorption rate of water to bait laser and strong stripping ability. Generally speaking, it has a great effect on superficial acne pits and spots. If the pit is too deep, don't repair it, and the effect is not great. Can be used for laser grinding in non-lattice mode.
Wavelength: 2940
Scaring takes about the same time as carbon dioxide lattice, so the risk of color precipitation is small and the price will be cheaper.
Applicable objects: surface pockmarks and small spots.
The top is the peeling laser, and the bottom is the non-peeling laser.
The more common ones are Confirm, Paloma and fractal (I don't know if the English name is misspelled). These lasers can heat the dermis without damaging the epidermis and achieve therapeutic effects. It won't scab when it's done.
Wavelength: about 1550.
Recovery period: 2-3 days
Course of treatment: theoretically, three times without peeling can be equal to one peeling, but (hehe)
The pain is not as severe as the previous two exfoliations, but the treatment effect will not be so good.
With a joke. (covering his face)
Plasma is called ion beam in Chinese.
Or a plasma laser. Some people say that ion beam is superior to carbon dioxide, but I have read many clinical papers and found that the therapeutic effects of the two are similar (although some people may be suitable for carbon dioxide and others are suitable for ion beam), but the risk of color precipitation of ion beam is less than that of carbon dioxide. To be sure, the ion beam is very painful, and it is very difficult for ordinary people to get anesthetized. When the ion beam is operated, it rolls like a roller instead of stamps.
Suitable objects: wheel-type acne pits, shallow horse-type acne pits.
Fourth, other methods to treat acne pits
TCA acid skin substitute
According to different concentrations, it can be divided into TCA peel and TCA cross. The former has a low concentration and is mainly used for changing skin and shrinking pores. The latter has a high concentration and is mainly used for acne pits. Its principle is strong acid corrosion, and then let the epidermis repair and grow. Some people say it can be used to treat ice cone acne pits. The treatment idea is to burn the pit with strong acid to make it longer and shallower, and then fill it with laser later. When you hear sulfuric acid disfigurement, you have a sense of sight. Remind the babies that it must be a medical institution to operate. China people's skin tends to turn black, which is not recommended.
A brave friend with an artist bought TCA acid online and made it at home. Bian Xiao expressed admiration for those heroes who are not afraid of disfigurement. )
Five, the treatment of complex (refractory) acne pits (acne friends must see)
Subcutaneous separation
The operation of subcutaneous separation is to insert the needle into the edge of the pockmark, and then rotate the needle parallel to the pockmark to separate the epidermis and dermis at the pockmark, thus cutting off the upper and lower adhered skin fibers and promoting the growth of dermis. It is said that it is cruel to hear the crackle of fiber breakage during surgery.
The doctor said: after subcutaneous separation, dot matrix laser can get better results.
Recovery period: The wound will be bruised and swollen after operation, which usually takes several weeks to recover.
Suitable target: Generally speaking, both roller-type and horse-type acne pits can be treated by subcutaneous separation.
Layered slit
For all kinds of difficult acne pits on the surface of the moon and all kinds of acne pits that are ineffective in treatment, you may really not find a suitable method.
For deep car-shaped pockmarked pits and ice cone-shaped pockmarked pits, the effect of laser drilling or strong acid cauterization will not be ideal, just like clothes with holes, laser drilling will only make the holes bigger and bigger, and the elevation will become a slope, which is not conducive to repair, so the layered cutting effect is better.
Treatment: Incision of epidermis and dermis (fat layer) according to specific conditions, thorough removal of contracture and subcutaneous tissue with inflammatory cells, cosmetic suture, and later laser treatment.
Applicable object: deep acne pits with good elasticity of surrounding skin (individual deep pits)
Cost: 300-600 yuan/piece (generally calculated according to the number of acne pits).
Micro dermal cell implantation
First, subcutaneous release and mechanical grinding were performed, and then cell implantation methods such as microparticle skin were adopted for surface transplantation.
Applicable objects: the skin is inelastic and widely fibrotic (pockmarked-pockmarked connection in a large area, pockmarked with skin wrinkles in severe cases).
Cost: there are not many hospitals that can do it, and the quotation is generally more than 20,000-30,000 yuan.
Subcutaneous separation, layered incision, and microparticle skin cell implantation are not many hospitals in China, and there are not many doctors who can do it. It may be because of high technical requirements and long operation time. Big coffee doctors have gone to do organ reconstruction, and junior doctors can't do this. "This thing can only take it slowly one by one. Ok, expensive, expensive and time-consuming. Doctors will engage in cervical spondylosis sooner or later. "
Sixth, those "pits" that cure acne pits are not expensive, in case they are effective. "Acne friends still don't take yourself as a mouse. Spending a little money is also money, not to mention the cost of time. Believe that these methods can go to acne pits? You better wake up!
microneedle
Microneedles are different, too. Microneedles in medical beauty institutions are not the same thing at all.
The micro-needle mentioned by beauty institutions is to use a very small needle (usually there are several small needles on a needle, or make a micro-needle roller) to pierce the skin, and according to the length of the needle, cause a wound in the epidermis or dermis, so that when applying skin care products in the later stage, it can go deep into the skin and get rid of the pressure of public opinion that "skin care products can't go deep into the skin at all". Of course, the stimulation of dermis in this process can promote the growth of collagen and repair acne pits more or less.
Micro-needles in medical and aesthetic institutions are quite destructive. The operation of "breaking the skin and seeing blood" will inevitably involve anti-infection and anti-scar surgery. If you try, you must go to a regular medical institution! ! !
Patients with superficial acne pits can try it. Doing it a few more times should make the scar shallow, but patients with deep pits should not move around, not to mention the pain of micro-needles.
In recent years, microneedles are very popular, and many people buy microneedles to operate at home. The sales of various musical instruments of a certain treasure can be seen. Remind babies that their surgery is very risky, and doing it badly is equivalent to disfigurement. )
Fruit acid skin changing
Strictly speaking, fruit acid (flower acid) skin rejuvenation does not have the function of repairing acne pits, but fruit acid skin rejuvenation can promote skin renewal and reduce the color deposition at acne pits, so it can make the color of acne pits close to the color of surrounding skin and make acne pits look less obvious.
Photon rejuvenation (intense pulsed light), red light and blue light, photodynamic
This kind of light is no longer in the range of laser. The main principle is that according to the different absorption characteristics of different tissues, light with different pulse widths and wavelengths is emitted for different skin problems (such as spots and acne marks) to achieve therapeutic effects. Red and blue light are mainly used to treat acne, diminish inflammation and produce oil, and the effect on acne pits is close to zero.
I hope this article can save some cost of finding information for friends with acne, or let friends with acne see some hope.
