Is fractional laser effective in removing acne marks? What are the disadvantages of laser acne marks removal?

There are many ways to remove acne scars. The fastest and most effective way to remove acne scars is medical beauty. Fractional laser acne scar removal is a very popular method. Fractional laser acne scar removal has advantages and disadvantages.

Fractional laser acne scar removal is one of the most effective ways to treat acne scars. Fractional laser acne scar removal does not thin the healthy skin to make it flush with the skin at the bottom of the pit. Instead, it stimulates the stem cells deep in the dermis (including mesenchymal stem cells in the dermis, stem cells in the appendages such as hair follicles, sweat glands, sebaceous glands, etc.) to become more active and promote skin regeneration. After fractional laser acne scar removal, fibroblasts in the dermis are activated and a large amount of matrix components such as collagen, elastin, and hyaluronic acid are synthesized. Therefore, after laser treatment, the skin continues to regenerate and gradually repairs the original sunken acne scars.

1. The disadvantages of laser acne removal: erythema

The disadvantages of laser acne scar removal include erythema, including temporary erythema and persistent erythema, which usually occurs after patients use fractional laser to remove acne scars. Since the treatment method of laser acne scar removal is to emit laser by scanning the dot matrix, a burning area composed of laser action dots and intervals can be formed on the epidermis. Therefore, it is inevitable that the skin tissue will be thermally damaged after the treatment, thus forming erythema after the acne scar treatment.

2. The disadvantage of laser acne treatment: darkening of the skin

Fractional laser treatment of acne scars and acne pits may cause the skin to darken again, which is related to factors such as skin color, postoperative cooling, tanning before laser treatment, the degree of laser damage to the skin barrier at the junction of the dermis and epidermis, the degree of inflammatory response, and laser parameters. If the patient who receives laser treatment for acne scars has been sunburned before, the chance of darkening will be greatly increased due to the deposition of melanin. In addition, if cooling measures are not taken in time after treatment, it will also cause darkening after laser treatment of acne scars.

3. The disadvantages of laser acne treatment: infection

Fractional laser therapy for laser acne scar removal may also cause infection. Because both ablative and non-ablative fractional lasers are invasive, infection may occur if instruments are not strictly sterilized during treatment. Clinically, symptomatic anti-infection treatments such as antiviral, antibacterial, and antifungal treatments are given to avoid various opportunistic infections and scars. People with low immune function should also be alert to various opportunistic infections when receiving fractional laser treatment.

4. The disadvantage of laser acne treatment: scars

Laser acne scar treatment may also cause scarring, and many girls are worried about this disadvantage. This usually happens when irregular fractional laser treatment is done or when there is no proper care after the fractional laser treatment. Scars appear because fractional laser damages the dermis of the skin. When the dermis of the skin is damaged and not properly protected, scarring will occur.

5. Disadvantages of laser acne removal: contact dermatitis

Fractional laser acne scar removal may cause the side effect of contact dermatitis. Due to the poor quality of anesthetic drugs (such as lidocaine ointment), the skin is irritated, which causes allergic reactions. Clinically, it can manifest as flushing, papules and blisters, and itching. Contact dermatitis has no direct relationship with the treatment of laser acne scar removal. Anti-allergic and symptomatic treatment can be selected.

Many girls want to use laser to remove acne scars, but they are more worried about the disadvantages of laser treatment. Here I would like to remind you that laser treatment of acne scars must be done in a regular plastic surgery hospital and by a professional doctor to avoid its disadvantages. Because the "doctors" in private studios, beauty salons, nail salons and even hair salons perform laser treatments, the consequences are often unbearable. In addition, it is likely that you will need to spend more money to find a professional doctor to repair it later.

1. Do not manually peel off the scab: The scab cannot be forcibly removed and should be allowed to fall off on its own. Otherwise, it will not only prolong the recovery process of the face, but may also cause scars on the wound surface.

2. Keep the wound clean and dry: The surgical wound should be kept clean and dry, and should not be scrubbed or exposed to sunlight. If necessary, apply antibiotic ointment topically, which can promote the recovery of laser acne marks.

3. Use the repair cream as required: To restore the skin texture to its natural state after laser acne scar removal, you must follow the doctor's plan and stop using it until the skin texture heals. After using laser acne scar removal, you must apply the repair cream 4 times a day. Before applying the repair cream, you must use a facial cleanser that does not contain fruit acid, soap, or therapeutic properties. You must use a non-foaming facial cleanser to thoroughly clean the affected area, then use a tissue to dry all the moisture, and then apply the repair cream.

5. Avoid hormone products: After laser acne scar removal treatment, you should be careful not to use inferior cosmetics and skin-repairing, peeling, and hormone products.

6. Avoid exfoliation and sauna: Do not exfoliate or use sauna within six months after laser acne treatment. Use sunscreen during the day and avoid direct sunlight when going out.

7. Maintain a happy mood: Maintaining a happy mood, avoiding excessive worry, and getting enough sleep are good helpers for recovery.

8. Use more vitamin C and vitamin E: People who seek beauty can eat more foods containing vitamin C and E to promote early skin recovery and pigment removal.
