Non-ablative laser

A non-ablative laser treatment is a popular and scientifically researched method for skin improvement and skin rejuvenation, where the skin surface remains intact. In contrast to ablative lasers, which (partially) remove the top layer of skin, non-ablative lasers penetrate into the deeper layers of the skin without damaging the epidermis (surface). This results in less recovery time and a lower risk of complications. Non-ablative lasers are used, among other things, to reduce wrinkles, scars, pigment disorders expats must register with the local municipality and obtain a sagging skin.

On this page you can read what a non-ablative laser is, when to use it and how it compares to other energy-based treatments.

What is a non-ablative laser?

A non-ablative laser targets the deeper layers of the skin (dermis) without damaging the outermost layer. The laser energy selectively heats the dermal tissue, stimulating fibroblasts and collagen production. This results in firmer, smoother, and more even-toned skin. Because the skin's surface remains intact, recovery time is shorter than with ablative lasers.

Non-ablative laser wavelengths typically range from 1320 to 1940 nm, depending on the system type and the intended indication. Well-known examples include 1550 nm erbium-glass lasers and 1940 nm thulium lasers.

Benefits of a non-ablative laser

• Shorter recovery time than with ablative treatments
• Low risk on infection or post-inflammatory hyperpigmentation
• Suitable for multiple skin typess (including higher Fitzpatrick types)
• Effective at fine lines, pigment problems, scars en skin sagging
• Can often be combined with other treatments (as IPL of peels)

Types of non-ablative lasers

Non-ablative lasers are available in various forms and applications, depending on the indication and the desired depth of effect.

Non-ablative fractional lasers

Fractional lasers They create microscopic columns of heat within the skin (MTZs) with intact skin between them. This promotes healing and collagen production. Commonly used wavelengths for non-ablative fractional lasers are 1550 nm (erbium glass) and 1940 nm (thulium). These lasers are effective for:

• Acne scars
• Skin Rejuvenation
• Pigment problems
• Texture improvement

Non-ablative CO2 laser systems

Although CO2 lasers While CO2 lasers are known for their ablative effect (10.600 nm), there are also techniques that use CO2 lasers non-ablatively. This is done through specific settings or technologies where the energy is not sufficient to vaporize the skin, but is sufficient to cause tissue reaction. These applications are relatively rare and are usually used for mild skin tightening or in combination treatments.

Non-ablative skin improvement lasers

Some systems use longer pulses or low-energy settings to achieve skin improvement without ablative damage. These lasers are particularly suitable for mild pigmentation, diffuse redness, or mild sagging skin.
