How is Kleresca® Acne Treatment different to other available light treatments?

The Kleresca® technology offers non-destructive, non-systemic, and painless treatments that use fluorescent light (FLE) energy to stimulate the skin’s own repair mechanisms, treating both active acne and acne scarring. 
The treatment is based on the interaction between a specially designed gel and the Kleresca® Light. Chromophores in the gel convert the blue light from the lamp into fluorescent light energy (FLE) that penetrates the skin and activates its healing responses.

What is the role of the Kleresca® gel in the treatment?

The chromophores in the gel convert the blue light from the Kleresca® Light into fluorescent light energy (FLE) that covers the spectra from green over yellow and orange to red (approx. 510 – 610 nm) at once. The fluorescence generated (dynamic, ultrafast pulsing light) penetrates different layers in the skin, activating its healing mechanisms. 

What are the benefits of Kleresca® Acne Treatment?

Kleresca® Acne Treatment is tough on acne, but gentle on skin. It stimulates the skin to repair itself:

  • Treats both active acne and acne scarring
  • Normalises the skin
  • Non-systemic, lasting up to a year and above
  • Suitable all year round, including summer

How soon will I see results?

You should see noticeable improvements in your skin during the last weeks that the treatment takes place. These improvements should also continue for months after the treatment has stopped. This is due to the activation of the deeper layers of the skin with the repairing continuing after the treatment has ended.

How long will the results last?

After finishing the treatment, the already normalised skin continues working and you can expect to see additional improvements to your complexion for months after the treatment has stopped. Persistence of efficacy has been demonstrated for at least 6 months. Experience from current clinics using Kleresca® Acne Treatment show that persistence can last for a year and above.

Which areas can be treated with Kleresca® Acne Treatment?

Kleresca® Acne Treatment can be used in all the affected areas with acne. This includes face, chest and back.

What is the recommended protocol?

The treatment’s recommended protocol will depend on your acne severity and your overall skin condition. We recommend that your clinician assesses the type of acne you have and defines the best regime for you and your skin.
The total number of treatments generally varies, depending on acne severity. For moderate to severe acne, we recommend 12 sessions, twice per week, for 6 weeks.

Is it painful?

The treatment is painless. Patients treated mention a warm and tingling sensation and describe Kleresca® Acne Treatment as pleasant and comfortable.

Is the light harmful?

The Kleresca® Acne Treatment uses a multi-LED lamp (Light Emitting Diode) as its energy source. Harmful UV light is not emitted by the system. With clinical trials showing high safety and efficacy, Kleresca® Acne Treatment is a well-tolerated treatment with no serious side effects reported.

Does the gel penetrate the skin?

The gel stays on the surface of the skin to convert the light emitted by the lamp into fluorescent light energy (FLE). FLE then triggers beneficial effects by stimulating the healing mechanisms in the multiple layers of the skin. 

What is the difference between Kleresca® FLE treatments and PDT?

PDT (Photodynamic Therapy) is a form of phototherapy that involves light and a topical drug that gets activated with the light. The drug will get absorbed by the patient’s skin and then be activated with the light to induce a destruction of skin cells for the treatment of some skin conditions.
FLE, on the other hand, is non-destructive, non-systemic and painless alternative to drugs. The gel is not being absorbed, it is only used to convert the blue light of the Kleresca® Light into Fluorescent Light Energy (FLE). Only the light will penetrate the skin and activate its own repair mechanisms.

Where can I get the treatment?

The treatment is offered exclusively in selected and certified Kleresca® clinics. Find your nearest clinic here.

Is Kleresca® Acne Treatment safe?

The technology has been on the market since 2014. 
Side effects – seen in some patients – are all non-permanent and may include redness, swelling, and hyperpigmentation (bronzing of an area of the skin). Side effects impact patients differently depending on skin type, so we always recommend talking to your clinician before beginning treatment.
