Personal Information

Form & Consent

INFORMED CONSENT

This complex and multifactorial indication generally requires 8 to 15 sessions. Treatments are performed during seasons when sun exposure is less intense.
The effectiveness of the treatment and its results over time are conditioned by the respect of a strict NO sun exposure. For better effectiveness, combined treatments are often recommended. Maintenance" sessions may also be recommended.

Principle of action

Spectra Q-Switched is an ultra-short pulse technology that breaks down pigments. They break up into smaller particles thanks to the thermomechanical effect.
The absorption of the laser beam is selective to the melanin without damaging the surrounding tissues (endogenous pigment of the spots, but also of the tanning, which is why the skin must not be tanned).
It is recommended to space the sessions from one to three weeks apart.

The steps of the session

1. The area to be treated must be cleaned and made up beforehand
2. Occlusive covers or protective glasses specific to the wavelengths used must be worn by the patient, the practitioner and any person present in the room.
3. The area(s) to be treated are scanned by the laser beam.
4. After the passage of the laser, the area shows a slight erythema.
Small spots or slight bleeding and transient edema may appear a few minutes after the treatment.
6. A repair cream is applied to the area.

The observed consequences

Possible crusts may fall off between 7 and 10 days, redness, swelling and a "sunburn" sensation may be felt a few hours to 72 hours after the session.
It is more than recommended to disinfect the area and apply a repair cream for at least 15 days following the treatment.
The application of a sun protection SPF 50+ for SIX WEEKS must be rigorously respected.
Post-treatment care must be properly performed to ensure proper healing of the procedure.

It is possible to observe transient changes in pigmentation (hyper-hypo pigmentation) which may remain visible for up to 6 months. The post-treatment recommendations, and in particular the application of a sun protection SPF 50+, must be correctly followed to limit this risk of side effect; the same applies to the risk of infection. It is imperative to follow the post-treatment instructions recommended by your practitioner.
The risk of minimal scarring side effects is extremely rare.
Laser light (1064nm) can cause eye damage. That is why it is mandatory to wear protective eyewear during the session.
