Will laser acne treatment leave scars? If it is not done properly, it will definitely leave scars

Laser acne scar removal is a very common beauty method nowadays. It is very useful for girls with acne scars on their faces and can help many friends who are troubled by acne scars regain their confidence. Below, the editor of No. 5.com will tell you whether laser acne scar removal will leave scars?

Will laser acne removal leave scars?

Under the guidance of experienced and responsible doctors in regular hospitals, laser acne treatment according to standard procedures will generally not leave scars on the skin. Although laser acne treatment is invasive to the skin, the trauma is not too deep, and there will be new collagen after laser acne treatment. The new collagen at the site of the trauma will smooth out the treatment marks of laser acne treatment, so there will be no scars after laser acne treatment.

The reason why many people get scars after laser acne scar removal is mostly because they received irregular or non-standard laser acne scar removal treatment. Irregular or non-standard laser acne scar removal operations cause the local skin to receive too much light and heat, which can easily cause deep trauma to the facial skin, resulting in the wound not healing on its own after laser acne scar removal, but leaving scars one month later.

How long does it take for laser acne removal to take effect?

The following are some common methods for removing acne marks. Let’s take a look at how long it takes for them to be effective!

It takes more than two months for red and blue light acne treatment to be fully effective

Red and blue light acne treatment is effective once, but it takes 8 treatments (one course of treatment) to be completely effective and basically eliminate acne. Each course of treatment needs to be separated by about 1 week, so it takes 8 weeks (more than two months) for red and blue laser acne treatment to be completely effective.

Photorejuvenation (intense pulsed light) is fully effective in 3 and a half months

Photorejuvenation can also treat acne. Generally, it needs to be done 5 to 6 times in a row, with an interval of 3 to 4 weeks between each treatment. In this way, it takes 3 and a half months to see the most obvious improvement in acne treatment. It should be noted that photorejuvenation is effective even after one treatment. However, it is impossible to achieve significant improvement in acne scars after one treatment. The effect of a single treatment is not obvious.

Fractional laser treatment of acne pits and acne scars was completely effective in 8 and a half months

Fractional laser is mainly used for acne-prone skin with acne pits and acne scars. The time it takes to see results varies from person to person, but after the first treatment, the scar condition will change. Fractional laser treatment is usually done every 50-60 days, and the number of treatments varies from person to person. It is common to completely improve acne pits and acne scars after about 5 treatments.

How laser acne scar removal works

The principle of fractional laser acne scar removal: fractional laser acne scar removal is to emit laser in a scanning dot matrix mode, which can form a burning area composed of laser action dot matrix and interval on the epidermis. Each laser action point can be composed of a single or several high-energy laser pulses, and the laser action point can directly reach the dermis and form a conical hole. Under the action of laser, the proliferation of tissue collagen is stimulated, and the reorganization of collagen is also promoted. In addition, the contraction repair of the conical hole will make the skin have a significant plump and tender effect, thereby significantly improving the acne scar phenomenon and quickly achieving the effect of tightening the skin. Make the skin delicate, smooth, and elastic, and improve the quality of the skin.

The principle of photorejuvenation for acne scars: Photorejuvenation for acne scars uses wavelengths that can be strongly absorbed by hemoglobin to treat acne scars. Without damaging normal skin, it coagulates blood vessels, decomposes pigments, and rearranges collagen and strong fibers under the skin, thus making acne scars disappear without a trace.

Laser acne scar removal precautions

Be careful to avoid foods with high pigments and light-sensitive foods

After finishing the laser acne treatment, you should pay attention to your diet and avoid eating foods with high pigment content. This is to prevent local pigmentation, such as coffee, photosensitive foods such as celery, and spicy foods.

Avoid exposure to sunlight

After laser acne scar removal treatment, you should avoid exposure to the sun, wear a sun hat when going out, use a parasol, and use sunscreen products (preferably SPF30-50 or above), otherwise your skin will easily get tanned.

Enhance skin moisturizing

After laser acne treatment, you need to strengthen skin moisturizing, because the light will take away some moisture during the photon action, so it is normal to feel dry skin afterwards. You must strengthen hydration, such as using a mask every other day in the first week, and it will be normal from the second week on. (However, you should avoid using irritating skin care products within one week after skin rejuvenation treatment, such as those containing fruit acid, A acid, high concentration of vitamin C, salicylic acid, alcohol, etc.).
