Analysis of leg birthmark removal methods:

Procedure Name	Chemical Peeling	Cryotherapy	Q-Switched Laser	Pulsed Dye Laser	Skin Grafting
Procedure Illustration
Principle	Apply fruit acid to the birthmark area, primarily acting on the epidermis to exfoliate the aging keratin layer	Use liquid nitrogen to freeze and destroy the local birthmark tissue, thereby removing the birthmark	Laser energy rapidly targets the affected tissue, causing the pigment in the lesion to gradually fade until it disappears	Laser wavelength is selectively absorbed by hemoglobin; damaged tissue is absorbed and metabolized by the body, gradually lightening the lesion	Transplant healthy skin from another part of the body to the birthmark area to cover it and promote healing
Duration of Effect	2–3 years	8–10 years	3–5 years	2–3 years	10–15 years
Estimated Cost	2,000–3,000 RMB per session	3,000–5,000 RMB per session	1,000–3,000 RMB per session	2,000–5,000 RMB per session	8,000–20,000 RMB per session
Advantages	1. Painless 2. Minimal trauma	1. High cost-effectiveness 2. Non-invasive and painless	1. Few side effects 2. High safety	1. High safety 2. Non-invasive with minimal damage	1. High precision 2. No rejection reaction
