The treatment

Learn how fluorescent light energy (FLE) stimulates the skin’s own rejuvenation process 

Ageing is inevitable, but skin doesn’t have to become dull and lifeless as time goes by.
Kleresca® Skin Rejuvenation reduces pore size, fine lines, and the appearance of scarring1-11. With a collagen boost of up to 400%6 it leaves the skin revitalized, firm, and glowing2,6,7

The difference is fluorescent

The treatment is based on the interaction between a specially designed photoconverter gel and the Kleresca® Light11,18.
Chromophores in the gel convert the blue light from the lamp into fluorescent light energy (FLE) that penetrates the skin and stimulates its own rejuvenation process1,6,11,18.
Noticeable improvements can be seen in the skin during the course of treatments – as well as long‑lasting improvements after the treatment has been completed1-11

Documented collagen increase1,6

In vitro studies show a significant up-regulation of 400% of collagen production after applying Kleresca® to human fibroblasts, which has also been confirmed from biopsies taken during a clinical trial.

The treatment improves the overall skin texture without causing any trauma1-11. Nothing added, just skin at its best.

Healthy skin no matter the age

Ageing is not a disease; it is part of life. Growing old is inevitable, and studies show that people lose 1% of collagen every year after reaching adulthood13,14
There are also many external factors that can affect the quality of the skin, like smoking, diet, sun damage…15
Kleresca® Skin Rejuvenation improves the overall skin texture, while also inducing a natural "glow" characteristic of young and healthy skin2,6,7. With fluorescent light energy (FLE), you can stimulate the skin’s own repair mechanisms while inducing the collagen production to obtain healthy skin no matter the age1-11.

Stimulate the skin’s own rejuvenation process

Studies with Kleresca® Skin Rejuvenation show that this gentle, yet effective and non-destructive treatment works by stimulating the skin’s own repair mechanisms1-11. The treatment reduces pore size, fine lines, and the appearance of scarring1-7. With a collagen boost of up to 400% it leaves the skin revitalised, firm, and glowing1,6,7.
The treatment has been shown to continue improving  skin quality even after the course of treatment has been completed1-11

How the treatment is performed12

The three-step treatment is described as a pleasant experience. It only takes nine minutes under the lamp. With little to no downtime, even make-up can be applied immediately after each session. 

Kleresca biophotonics technology

1. The skin is cleaned and Kleresca® Skin Rejuvenation gel is applied.
