Luxury skin-care range 111 Skin is founded by British and American board-certified cosmetic surgeon Dr Yannis Alexandrides, who has a practice on Harley Street in London. The brand's newest product, the 111 Skin Celestial Black Diamond Neck and Décolletage Serum (£250), is inspired by a cosmetic procedure Dr Alexandrides carries out in his practise called the Y-lift Surgery, which lifts the face, jawline, and neck of the patient. Whilst a topical product could never deliver the same results as surgery, this serum contains a potent peptide complex that promises to stimulate collagen production, which in turn has a lifting, firming, and toning effect on the neck and chest area with repeated use. Additionally, it contains moisturising ingredients and lactic acid that will help plump the skin and fade any discolouration.
