Medik8 Crystal Retinal 6 Serum (0.06% Retinaldehyde) Delivering gentle yet effective age-defying results, Medik8 Crystal Retinal 6 Serum is an advanced retinaldehyde treatment designed for experienced vitamin A users. Powered by 0.06% stabilised retinal, the fast-acting formula works overnight to visibly smooth, firm and refine the complexion while protecting against noticeable signs of ageing. Utilising encapsulation technology, the retinal is released gradually into the skin to maximise efficacy while minimising irritation. Retinaldehyde, a potent derivative of vitamin A, is renowned for working up to 11 times faster than traditional retinol*, helping to improve skin texture, tone and clarity with visible results. The serum is enriched with hyaluronic acid and glycerin to hydrate and plump the skin, while vitamin E provides antioxidant protection against environmental aggressors. Together, these ingredients help to diminish the appearance of fine lines, uneven texture, dullness and discolouration, promoting the look of enhanced elasticity and bounce. Dermatologist recommended, the Crystal Retinal range features a unique ladder of progressive strengths (0.01%–0.2%), allowing users to safely build tolerance and achieve optimal results at every stage of their retinal journey.
