Frequently Asked Questions

Get more information about Kleresca® Pre-Post Treatment 

How is Kleresca® Pre-Post Treatment different from other available light treatments?

The Kleresca® technology offers non-destructive, non-systemic, and painless treatments that use fluorescent light  energy (FLE) to stimulate the skin’s own repair mechanisms2-12.
The treatment is based on the interaction between a specially designed gel and the Kleresca® Light1-3,12. 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. 

How is the fluorescence created?

The chromophores in the gel convert the blue light from the lamp into fluorescent light energy (FLE) that covers the spectra from green over yellow and orange to red at once2,3,12
The fluorescence generated (dynamic, ultrafast pulsing light) penetrates the different layers of the skin, triggering documented healing responses and activating their healing mechanisms2,3,12

What are the benefits of Kleresca® Pre-Post Treatment?

Kleresca® Pre-Post Treatment is used in combination with skin procedures like peels and lasers8,12. Through fluorescent light energy (FLE), the treatment activates the skin cells in a non-destructive, yet effective manner2-12 

  • Prepares and repairs the skin from within
  • Activates skin cells prior to other skin procedures
  • Reduces inflammation, redness, and healing time
  • Suitable all year-round, including summer

What is the recommended protocol?

The recommended protocol depends the type of the invasive treatment used and the healing time that the skin might need, but generally, a total  of 4 – 5 sessions is recommended1
It is common to provide 1-2 sessions before applying an invasive treatment to prepare the skin. Once this treatment is finished and the skin has no open wounds, it is common to follow up with 2-3 sessions1,8,11

Which products are currently available on the Kleresca® technology platform?

Currently, four products are available on the Kleresca® technology platform: Kleresca® Acne Treatment, Kleresca® Rosacea Treatment, Kleresca® Skin Rejuvenation and Kleresca® Pre-Post Treatment. Each indication features a specifically formulated gel. This is then utilised with specific pre-programmed settings in the Kleresca® Light. 

Is the treatment painful?

Patients that use the treatments generally describe it as pleasant and comfortable. They mention a warm and tingling sensation while they are under the lamp3-12
The treatment is non-destructive, non-systemic, and painless and it does not cause any harm to the skin tissue. The treatment acts by activating the skin’s cells and own repair mechanisms2-12.  

Does the gel penetrate the skin?

The gel stays on the surface of the skin and its purpose is to convert the light emitted by the lamp into fluorescent light energy (FLE). This fluorescent light energy (FLE) then provides beneficial effects by way of modulation of the biological processes in the multiple layers of the skin1-12

Is the light harmful?

The Kleresca® Pre-Post Treatment uses a multi-LED lamp as its energy source and emits in the blue light area, within the visible light spectrum. No harmful UV light is emitted by the system1,2,11. Clinical trials have shown that Kleresca® is a well-tolerated treatment with no serious side effects reported2-12.

Can any LED lamp be used?

The patented Kleresca® Light, with pre-programmed wavelength settings specific to each indication, has been developed and tested to efficiently cause the chromophores to photoconvert blue light, thereby creating fluorescent light energy (FLE)12.

Can Kleresca® be used during summer2-12?

Yes. Kleresca® Treatments do not induce photosensitivity and patients do not need to avoid sun exposure during or after the treatments. However, people should protect themselves against the harmful UV light of the sun with a broad spectrum sun screen. 
Kleresca® FLE treatments are generally gentle and comfortable. Being non-invasive, there is no destruction or removal of the skin’s natural barriers. The gel used during the treatment is not absorbed by the skin, so no substance in it can induce a photosensitive reaction.

What type of training is provided to professional clinic staff?

The system is easy to use and complementary training is also offered as part of a certification program for clinic staff.

Is Kleresca® Pre-Post 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)2-12. Side effects impact patients differently depending on their skin type, so we always recommend talking to your clinician before beginning treatment.
