The laser skin resurfacing (also known as laser resurfacing) is a dermatologic-aesthetic procedure used to improve the appearance of the skin, reduce fine lines, wrinkles, dark spots and scars, and refine skin texture. Below is a summary of the most important information:

What happens during laser resurfacing?

There are two main types of lasers used for skin rejuvenation:

1 - Ablative lasers

They remove the top layer of skin (epidermis) and stimulate the production of new collagen in the underlying dermis.

Examples:

Laser CO₂ laser.
Erbium:YAG laser

They are more effective, but require a longer recovery time (1-2 weeks).

2 - Non-ablative lasers

They penetrate into the deep layers of the skin without damaging the surface and stimulate collagen production.

Examples:

Fraxel laser
Nd:YAG laser

What can be treated?

Fine lines and wrinkles (e.g., around the eyes and mouth)
Sun damage and pigmentation
Acne or surgical scars
Enlarged pores
Uneven skin tone
Loss of elasticity

Duration and number of sessions

Duration: approx. 20-60 minutes, depending on the area
Number of sessions: 1-5 (non-ablative), sometimes only 1 in ablative procedures
Interval: usually 4-6 weeks between sessions

Recovery and aftercare

Ablative lasers: redness, scabbing and swelling - 1-2 weeks recovery time
Non-ablative lasers: slight redness and swelling, no open wounds
Important: use of sunscreen (SPF 50), avoid aggressive products, saunas and solariums during the first few weeks

Risks and side effects

Redness and swelling
Pigmentation changes (especially in dark skins)
Scars (rare, usually due to improper care)
Infections (e.g., reactivation of cold sores)

Suitable for:

Mild to moderate signs of skin aging
Acne scars or pigmentation disorders
Fair skin (less risk of hyperpigmentation)

Not suitable for:

Active skin infections
