Information from the brand
Product description

Product code: 47160907

Formulated with stabilised retinal, a powerful derivative of Vitamin A with next-generation anti-ageing results.

Unmatched in its age-defying power, retinal can deliver results comparable to clinical-grade Vitamin A up to 11 times faster than classic forms of retinol.*

*G. Siegenthaler et al., Retinol and retinal metabolism, Biochemical Journal, 1990, 268, pp 371-378.

The ground-breaking overnight serum visibly minimises fine lines and wrinkles; firming and plumping the complexion to resurface skin texture and soften the face.
