Skin Booster Bio-Fermented Serum with Äio RedOil, Hyaluronic acid, algae and Black Currant Seed oil

In stock

A world first! The Skin Booster Serum is the first product ever made with ÄIO RedOil. ÄIO RedOil is an upcycled ingredient – a fermented oil derived from organic side-stream.


A silky, fast-absorbing facial serum that brings together the strength of the sea and the forest. Formulated in synergy with Nordic and marine algae, this serum helps restore skin elasticity while delivering deep hydration, soothing care, and daily protection. The result is skin that feels soft, balanced, and visibly healthier.

At the heart of the formula is ÄIO’s RedOil, derived through the fermentation of upcycled forestry by-products and inspired by nature’s most efficient processes. RedOil is a natural non-irritant alternative to retinol with strong cell renewing properties whilst supporting skin’s natural barrier. It is rich in antioxidants, helps reduce redness and strengthens the skin against environmental stressors.

Cold-pressed black currant seed oil complements the formula with essential fatty acids, including gamma-linolenic acid, helping to calm inflammation, support regeneration, and reinforce the skin’s natural barrier. Suitable for both sensitive and acne-prone skin.

Low molecular weight hyaluronic acid provides multi-level hydration, leaving the skin plump, smooth, and deeply moisturised. A blend of Natural Moisturising Factors (NMF), including Sodium PCA, urea, and amino acids, supports long-lasting hydration and skin balance.

Niacinamide (Vitamin B3) enhances the formula by improving skin tone, reducing redness, and promoting a more even, radiant complexion.

Usage: Apply a few pumps of the serum to clean skin before cream, both morning and evening.
