A more intensive version of their original Y Theorem Serum, this potent Celestial Black Diamond Serum is formulated to deliver effective youth-prolonging results by encouraging collagen and elastin production.

Infused with black diamond particles to deliver the active ingredients deep into your skin, this serum works to hydrate, smooth, plump and brighten your skin. It’s powered by liquorice root to reduce the appearance of pigmentation and discolouration for a brighter, consolidated complexion; quebracho wood treats inflammation and shields against environmental aggressors, while low molecular weight hyaluronic acid hydrates deeper layers of skin to alleviate tightness and irritation.

Apply one pump morning and evening, on clean, dry skin. Follow with moisturiser.

Formulated by globally renowned Harley Street cosmetic surgeon, Dr. Yannis Alexandrides, 111SKIN’s space scientist-developed formulas are the go-to range for skin-savvy celebrities, beauty editors and skin care obsessives alike. Now you can reap the rewards of this highly effective range in the comfort of your own home with their Celestial Black Diamond Serum – a concentrated, age-defying formula that targets a plethora of concerns: from boosting elasticity and firmness to diminishing hyperpigmentation, discolouration and uneven skin tone.
