Key Ingredients

Niacinamide

Known for its ability to help brighten the appearance of skin, support healthy ageing including the appearance of fine lines, wrinkles, elasticity and hyperpigmentation, and help support skin strength and barrier function.

Panthenol

Its humectant properties keeps skin hydrated by maintaining moisture levels and supporting the skin barrier function for optimal hydration. It also helps soothe and calm to comfort irritated skin.

Aphanothece Sacrum Exopolysaccharides

Extracted from the Japanese blue-green algae that lives in the clear springs of Mount Aso and can only flourish in pristine conditions, its high molecular weight delivers superior hydration and can absorb 5x more water than sodium hyaluronate. It also has a unique ability to form a transparent film over skin to help support skin integrity and support a healthy response to pollutants, leaving skin soft and hydrated.

Ethyl Linoleate

Combining two essential fatty acids, linoleic acid (omega-6) and linolenic acid (omega-3), it helps support the skin’s barrier, reduce irritation, and calm skin. It also hydrates and retains moisture, is suitable for highly sensitive skin, and can help control acne.

Glycerin

A natural humectant, it is an incredible moisturising and skin-replenishing ingredient as it helps attract moisture from the air and deliver it deep into the lower layers of the skin to the epidermis. It leaves skin moist, bouncy and dewy, and also helps maintain skin health when using active or drying products. Our Glycerin is Palm-Free.

Cucumis Sativus (Cucumber) Extract

A non-sensitising plant extract, it’s rich in minerals, fatty acids and vitamins A, B, C and E. It has antioxidant properties and helps hydrate, refresh, and soothe skin.

Propanediol

Derived from corn sugar, it functions as a solvent, humectant, emollient and a preservative booster. It helps improve the texture of products, and the absorption of ingredients to boost their effectiveness. It also has moisturising properties to leave skin feeling smooth and soft while reducing moisture loss.

Salicylic Acid

A Beta Hydroxy Acid that gently exfoliates the surface of skin and helps regulate oil production, target congestion, reduce blackheads, control inflammation from acne and pimples, and support healthy pigmentation and healthy skin renewal. It also works to support the effectiveness of Vitamins A and C, as well as Alpha Hydroxy Acids.

Cocos Nucifera Fruit Juice

Fermented Coconut Juice is a postbiotic ingredient produced by the fermentation of lactic acid bacteria. It has antioxidant, antimicrobial and moisturising benefits to help maintain the balance of the skin’s microbiome to keep it healthy. It also stimulates Collagen 1 synthesis, which helps support healthy skin resilience, and stimulates Collagen 3, which helps promote skin health and the appearance of elasticity.

Arthrospira platensis

A microalgae rich in proteins and carotenoids with antioxidant and antibacterial benefits, it's been shown to help improve the skin's appearance and health, and promote wound healing while boosting hydrating and improving the skin barrier function.

Aloe Barbadensis (Aloe Vera) Leaf Extract

A natural ingredient rich in vitamins, minerals, and antioxidants. Its moisturising properties help to nourish and hydrate the nails, reducing dryness and brittleness. It also has anti-inflammatory and antimicrobial properties which help to prevent infections and soothe irritation, promoting overall nail health.

My skin is glowing

This is my first serum and I was a little sceptical. I paired this with the Kester black moisturizer and cleanser and my skin has never looked so good. Don’t think I can revert back to my non serum days. My skin is glowing!
