Introduction

In general, laser treatment can effectively address acne scars and post-inflammatory hyperpigmentation. A detailed analysis is as follows: Acne scars refer to depressed scars left after acne heals, while post-acne marks refer to pigmentation or redness remaining after acne subsides. The principle of laser treatment for acne scars and marks involves utilizing the selective photothermolysis of laser energy to stimulate collagen regeneration and remodeling in the skin, as well as promoting the metabolism and absorption of pigmentation.

Generally speaking, laser treatment can effectively address acne scars and post-inflammatory hyperpigmentation. The detailed explanation is as follows:

Acne scars refer to the depressed scars left after acne heals, while acne marks refer to the pigmentation or redness remaining after acne subsides. Laser treatment works based on the principle of selective photothermolysis, stimulating collagen regeneration and remodeling, as well as promoting pigment metabolism and absorption.

Fractional laser is commonly used to improve acne scars. It creates microscopic zones of thermal damage on the skin surface, triggering the skin's natural healing process, promoting collagen production and skin tissue reconstruction, thereby improving acne scars. Laser treatment is also highly effective for acne marks, particularly red and brown marks. Red acne marks result from post-inflammatory dilation of blood vessels, and laser treatment can seal these dilated vessels, reducing redness. Brown acne marks are caused by excess melanin deposition, and laser treatment can accelerate pigment metabolism and absorption, thus lightening the marks.

Prior to undergoing laser treatment, it is recommended to consult with a dermatologist to understand your skin condition, as well as the indications, contraindications, and potential risks and complications associated with the treatment. Additionally, during the treatment process, it is important to follow the physician's recommendations and instructions, and to observe proper post-treatment care and sun protection to promote skin recovery and reduce the risk of hyperpigmentation.

Which is better for treating filiform warts: cryotherapy or laser treatment?

Cryotherapy usually involves a short single procedure time, but it may take 1–2 weeks for the warts to shed. Larger warts may require multiple treatments. Laser therapy can directly vaporize the wart and remove it in a single session, with a postoperative recovery period of approximately one week, making it more efficient overall. Cryotherapy destroys warts through low temperatures and may result in blistering and crusting after treatment, with a relatively larger wound area.
