CLINICALLY TESTED AS SAFE

HET-CAM EYE IRRITATION TEST

The Lightening Serum by 28³® was classified as non-irritating to the eye and is therefore safe to use at the eye contour area.

Did you know?

The HET-CAM test is a cruelty-free alternative to animal testing. In the past, skincare products were applied onto rabbits' eyes to test its irritancy potential. In line with our commitment to cruelty-free products, 283® products are not and will never be tested on animals.

HRIPT HYPOALLERGENICITY TEST

The Lightening Serum by 28³® was classified as non-irritating to the skin and does not induce contact sensitisation with repeated use.

Did you know?

Contact sensitisation is a process where the skin develops increased sensitivity to a product with repeated exposure. With contact sensitisation, reactions may be minimal or absent with the first contact, but the skin may react to subsequent applications in a more severe manner.

Hypoallergenic products such as The Lightening Serum by 28³® do not induce contact sensitisation.
