One of Dermalogica's hero treatments, BioLumin-C Serum is a high-performance Vitamin C serum that works with the skin's own defences to brighten, firm and visibly smooth. Advanced bio-technology pairs an ultra-stable Vitamin C complex with a firming peptide and gentle AHA, so the antioxidant stays potent and the results show.

The stabilised Vitamin C brightens and helps defend against free-radical damage, Lactic Acid gently exfoliates to even out unbalanced pigmentation, and Palmitoyl Tripeptide-5 supports firmness and reduces the look of fine lines. Hyaluronic Acid keeps skin hydrated and plump throughout.

Ideal for dullness, uneven tone, dark spots and early signs of ageing, it suits most skin types and layers easily under moisturiser. Use morning and night, and always follow with SPF during the day.
