What is Frax laser?
Frax laser is a non-ablative fractional laser developed by Nordlys (Frax Pro system) that works in the deep dermis through microcolumns of controlled heat, leaving the epidermis intact. This action stimulates the natural synthesis of collagen and elastin and produces progressive skin remodeling.
Frax is a non-ablative fractional laser that spares the epidermis and works on the dermis with microcolumns of heat to produce new collagen. The key difference between Frax 1550 and Frax 1940
Frax is a non-ablative fractional laser that spares the epidermis and works on the dermis with microcolumns of heat to produce new collagen. The key difference between Frax 1550 and Frax 1940 is depth: 1550 nm works on scars, stretch marks and deep texture; 1940 nm corrects dark spots and superficial sun damage.
Areas we treat with Frax laser
Full face
Forehead, cheeks, jawline, perioral and periocular areas. The most requested area for texture, pores and fine lines.
Neck and décolletage
Areas with thin skin that is highly exposed to the sun; Frax restores firmness and an even tone.
Body
Sun damage on the décolletage, back, arms and legs; skin firming in areas with early laxity.
Acne and surgical scars
Atrophic scars (ice-pick, boxcar, rolling) and post-operative scars. Frax 1550 is the non-ablative gold standard.

Evidence and medical backing
Frax laser is authorized and registered as a medical device with medical CE marking by the Spanish Agency of Medicines and Medical Devices (AEMPS) and endorsed by the Spanish Society of Aesthetic Medicine (SEME) and the Spanish Society of Medical-Surgical Laser (SELMQ).
Published studies show:
- 40-70% improvement in atrophic acne scars after 4-6 sessions (Manuskiatti et al., Lasers Surg Med).
- 25-50% reduction in pigmentation of age spots and melasma with Frax 1940 nm.
- Measurable increase in type I and III collagen density from the 4th week after the session.
- Compatible with Fitzpatrick skin types I-V (including darker skin, where other ablative lasers are contraindicated).
The final indication is always signed off by a licensed aesthetic doctor after a NESAI® ultrasound assessment, not by a technician.
What does Frax laser treatment involve?
The treatment is carried out entirely in the medical office at Instituto de Benito in Barcelona or Madrid, in an outpatient session always designed and performed by a licensed aesthetic doctor.
Personalized medical assessment
The aesthetic doctor studies your case, rules out contraindications and designs a personalized plan. The first aesthetic medicine consultation costs €50 (deductible from your first treatment).
Skin ultrasound with NESAI
When the doctor considers it necessary, a NESAI Derm ultrasound is performed in Barcelona to assess the skin before treating: dermis thickness, density, collagen, fibers and sun damage.
Preparing for the treatment
Arrive with clean skin, with no makeup, creams or self-tanners. Avoid intense sun exposure for 15 days beforehand. A topical anesthetic cream is applied for 30-45 minutes to minimize discomfort. If you take anticoagulants or oral retinoids (isotretinoin), let us know at your consultation.
Treatment application in the clinic
The doctor passes the Frax handpiece over the area, with a cold air system for comfort. You will feel a controlled warm prickling sensation. The duration ranges from 20 minutes (localized area) to 45 minutes (face + neck + décolletage). You return to your normal life as soon as you leave.
Start seeing yourself the way you want to feel
The first changes (radiance, texture) are visible in 7-14 days. The full result can be seen between 3 and 6 months after completing the plan, thanks to the progressive formation of new collagen.

- Erythema and a sensation of heat.
- Mild edema (swelling), especially on the cheeks and eyelids.
- Pinpoint micro-scabs that fall off in 4-7 days.
- Mild itching during healing.
What are the less common side effects?
- Transient post-inflammatory hyperpigmentation (more common in skin types IV-V).
- Temporary hypopigmentation.
- Reactivation of cold sores.
- Contact dermatitis from post-treatment skincare.
What are the rare complications?

Frequently asked questions
What exactly is Frax laser?
Frax laser is a non-ablative fractional system from Nordlys that delivers microcolumns of heat into the dermis to stimulate collagen and elastin without damaging the epidermis. It is applied at two wavelengths (1550 nm and 1940 nm) depending on the indication.
What is the difference between Frax 1550 and Frax 1940?
Frax 1550 reaches deeper (up to 800 µm) and is the one indicated for acne scars, stretch marks, texture and pores. Frax 1940 works more superficially and is the option of choice for dark spots, sun damage, melasma and keratosis. In many cases the doctor combines both in the same plan.
How many sessions does it take to see results?
You will notice radiance and improved texture from the 1st-2nd session. For scars and stretch marks, 4-6 sessions are recommended, 4 weeks apart. The final result settles 3-6 months after the last pass.
Is it painful?
No. We apply topical anesthesia 30-45 minutes beforehand and the handpiece has built-in cold air. The sensation is one of heat with a controlled prickling, which is perfectly tolerable.
Is Frax laser the same as CO2 laser?
No. CO2 is ablative (it vaporizes the epidermis and requires 7-10 days off work). Frax is non-ablative: it spares the epidermis and lets you return to normal life immediately. CO2 gives more dramatic results in a single session, but Frax is safer, more versatile and compatible with darker skin types.
Is Frax laser safe for dark skin (skin types IV-V)?
Yes. Frax is one of the few fractional lasers that is safe up to Fitzpatrick skin type V, always with parameters adjusted by the doctor after NESAI®. Skin type VI requires strict assessment.
How much does a full Frax laser treatment cost at Instituto de Benito?
Frax laser has two rates: €250 per session for a small area (isolated scar, localized dark spots, hands) and €350 per session for a standard area (face, neck, décolletage or body stretch marks). The 4-session package applies a 15% discount (€850 or €1,190). The first medical consultation is €50, deductible from your first treatment.
Can I have Frax laser in summer?
It is preferable to avoid it between June and September or if you have tanned skin, due to the risk of hyperpigmentation. If you do have it, strict SPF 50+ will be mandatory and you must avoid sun exposure for 4 weeks.
How long do the results last?
The effects of the new collagen last 12-18 months. We recommend one maintenance session a year to preserve skin quality.
Can I combine Frax laser with botulinum toxin or hyaluronic acid?
Yes. The most requested protocol is Frax + biorevitalization or Frax + biostimulation with polylactic acid. Botulinum toxin and fillers are preferably applied 2 weeks before or 4 weeks after Frax.
Can I go to work the day after Frax laser?
Yes. You will have mild erythema and slight swelling for the first 24-72 hours, which can easily be covered with makeup after 24 hours. No time off work is required.
Can I have Frax laser if I have melasma?
Melasma is preferably treated with Frax 1940 nm at gentle settings combined with medical depigmenting agents. It is a delicate indication that requires assessment by an expert aesthetic doctor, as an aggressive protocol can make it worse.
