How the treatment works

Kleresca® Acne Treatment uses fluorescent light energy (FLE) to stimulate the skin’s own repair mechanisms2-12. The treatment is based on the interaction between a specially designed photoconverter gel and the Kleresca® Light1-3,12.

The chromophores in the gel convert the blue light from the lamp into fluorescent light energy that covers the spectra from green over yellow and orange to red (approx. 510 – 610 nm) at once2,3,12. The fluorescence generated (dynamic, ultrafast pulsing light) penetrates the multiple layers of the skin,triggering documented healing responses2,3,12-16.

How the treatment is performed

Patients typically describe the three-step treatment as a pleasant experience2-12. It only takes nine minutes under the lamp1. With little to no downtime, make-up can be applied immediately after the session1,12.

1. The skin is cleaned and Kleresca® Acne Treatment gel is applied.

2. The gel is illuminated for nine minutes using the Kleresca® Light; fluorescent light energy (FLE) is created stimulating the skin's own repair mechanism.

3. The gel is removed and the skin is cleansed and moisturized.

High-efficiency and painless2-6

In a randomised, multi-centre, split-face clinical trial with patients suffering from moderate to severe acne, patients were followed during treatment (twice per week for 6 weeks) and afterwards for an additional 6 weeks in order to study the long-lasting effects5.

Clinical trial results5:

89% response rate (patients ≥ 1 IGA* grade improvement)
52% of patients with ≥ 2 IGA grades improvement
33 % of patients reached clear or almost clear skin
81% of patients ≥ 40% reduction in inflammatory acne lesion counts
No serious adverse events reported
All adverse events were transient and did not require any intervention by the clinic


The treatment was considered to be well-tolerated, with no serious adverse events

Patients' quality of life improved

The treatment was found to be efficacious and safe

Sustained efficacy4

Robust data from an extension trial confirms the high efficacy and persistence of Kleresca® Acne Treatment.

Read summary

Clinical trial results4

Persistence of efficacy was demonstrated for at least six months, with the two grade or better improvement from the first trial maintained in 92% of patients. No patients reverted back to baseline. Patient safety profile was also excellent, with very few related adverse events. Based on experience from current clinics, patients treated with Kleresca® Acne Treatment show results lasting up to a year or above.


"Study confirmed the long duration of effect following treatment"

"Patient safety profile was excellent, with very few related adverse events"

"Kleresca® Acne Treatment provides long-term efficacy and safety in the treatment of acne vulgaris, with a rate of compliance above what is generally observed in a young population"

Safety information

The Kleresca® Acne Treatment takes place on your skin and is not absorbed or metabolised, making it a well-tolerated treatment option for acne. In clinical trials, Kleresca® Acne Treatment showed high safety with no serious adverse events, and the treatment itself was considered to be a pleasant and comfortable experience. Side effects seen in those treated include, redness, hyperpigmentation (bronzing of an area of the skin) and slight discoloration of hair in some cases where the gel was applied covering facial hair. All side effects were transient and did not require any intervention by the clinic.
Side effects impact patients differently depending on the skin type.
Kleresca® Acne Treatment is not recommended in the following situations:
1. Patients taking drugs or products (e.g. retinoids) or with conditions (e.g. porphyria) known to induce photosensitive reaction.
2. Patients with known skin hypersensitivity.
