Intentional Nutrients

  • Azeloglicina

    A derivative of azelaic acid used for it's brightening effects due to its ability to reduce the appearance of dark spots and hyper-pigmentation. It's effective in managing acne due to its anti-inflammatory properties and ability to reduce redness. It is also a mild exfoliant, keeping pores clear, without being acidic which can damage the barrier function.

  • Glutathione


    A tripeptide (derived from glutamic acid, cysteine and glycine) and the body's key and most powerful anti-oxidant, the production of which slows down as we age. Fiercely protects against cellular degradation and hyper-pigmentation and fights off free-radical attack. In our view one of the greatest anti-oxidants.

  • Gotu Kola

    Also known as Centella asiatica, Gotu Kola is a herb traditionally used in Ayurvedic and traditional Chinese medicine. Known for its excellent anti-ageing, hydrating and anti-inflammatory properties which help soothe and calm irritated skin. Gotu Kola stimulates collagen synthesis, promoting skin elasticity and firmness.

  • MSM

Proven reduction of fine lines, helps conditions from acne and eczema to leaky gut syndrome, damaged joints, arthritis, osteoporosis and psoriasis.

  • Vitamin B3 (Niacinamide)

    Improves skin hydration, elasticity, barrier function and skin tone. Improves skin health by reducing inflammation, minimizing pore size and addressing issues like acne and hyperpigmentation. Reduces water loss by 24% in 4 weeks, boosts fatty acid and ceramides by 67% and 34% respectively; stimulates new fibroblasts by 20% and collagen secretion by 54%; inhibits pigmentation by 68%.

  • Image of Snow Algae


    Coenochloris Signiensis Extract is a unique red extremophile algae that has managed to create survival strategies which enable them to grow on glaciers and snow. In order to survive in these harsh conditions, the snow algae have developed a kind of “sleeping beauty” tactic. It stimulates the longevity gene Klotho and activates AMPK, a master switch in the cellular defence and energy system. Snow Algae improves skin structure, slows down ageing process of skin cells, increases production of collagen, protects and activates longevity factors in skin cells, rejuvenates and protects skin at cellular level, all leading to reinforced, smoother glowing and hydrated skin.

  • Vitamin C

    Sodium Ascorbyl Phosphate (Vitamin C)

    A Vitamin C derivative with extreme anti-oxidant capacity and well-documented skin health benefits. Firms skin due to fibroblast generation which reduces skin permeability. Boosts collagen production to reduce fine lines and brightens skin due to its anti-oxidant capacity. One of the most stable and potent forms of Vitamin C, proven to reduce melanogenisis in the melanocytes by 57% and age spots by 25% using only 0.14%.

  • Swiss Glacier Water

    Encapsulated Swiss Glacier Water

Including glycine in skincare products can support the skin's ability to repair itself.

  • Lysine

    A key amino acid that plays a role in collagen synthesis, which is crucial for maintaining skin's elasticity and firmness. Can support barrier function, important for maintaining hydration and protecting against external irritants. Also has wound healing, antiviral and antioxidant properties.

  • Arbutin

    Known for its skin-brightening and pigmentation-reducing properties. Designed to address hyperpigmentation issues and promote a more even, radiant complexion. Arbutin works by inhibiting the enzyme responsible for melanin production, which can help lighten dark spots, hyperpigmentation, and uneven skin tone.
