The Gluconolactone + Booster is specially designed for dry, sensitive skin that needs renewal and radiance without tolerating harsh exfoliants. What makes it so gentle for this skin type is the combination of its star acid, Gluconolactone (a PHA, or polyhydroxy acid), with a base of anti-irritant actives: Aloe, Calendula, Witch Hazel, Pentavitin™, Hidroviton™, NMFs and Prebiotics. On top of this, its fragrance-free, silicone-free, oil-free formula with no added fragrances minimises the risk of adverse reactions. With a pH of 4.0 and a water-based formula, it is a toner formulated to offer equal parts efficacy and tolerability.
The Gluconolactone + Booster concentrates a multi-acid, hydrating formula with ingredients that have clearly defined roles. Gluconolactone (6%) is a PHA with gentle exfoliating and hydrating action, ideal for sensitive skin. Lactic Acid (2%) is a AHA that gently exfoliates and improves hydration. Niacinamide (4%), or vitamin B3, helps even out skin tone, reduce hyperpigmentation and strengthen the skin barrier. Aloe soothes and smooths; Calendula provides anti-inflammatory and repairing properties; and Witch Hazel helps tone and soothe the skin. Pentavitin™ and Hidroviton™ are hydrating complexes that provide deep, long-lasting moisture, while NMFs (Natural Moisturising Factors) keep the skin barrier healthy. Lastly, Prebiotics support a balanced skin microbiome, reinforcing the skin's overall health.
The Gluconolactone + Booster is applied directly with your hands onto clean, dry skin, spreading it over the face, neck and décolletage until fully absorbed. No rinsing is required. It is recommended to use it at night and apply sun protection rigorously on the following days. Before adding it to your routine, it is advisable to carry out a patch test beforehand and introduce it gradually according to individual tolerance. Avoid contact with mucous membranes and the eye area, and keep out of reach of children.
From the very first applications, the toner speeds up cell renewal and provides instant radiance, leaving skin looking brighter and revitalised. With continued use, the combination of Gluconolactone, Lactic Acid and Niacinamide works in depth to reduce and diminish the appearance of dark spots, marks and post-inflammatory hyperpigmentation, helping to even out skin tone. It also stimulates collagen and elastin production, resulting in progressively firmer, more elastic skin. At the same time, the moisturising actives and prebiotics keep the skin barrier balanced and the microbiome healthy, strengthening the skin's overall health.
Yes, its formulation is designed precisely for those who have struggled with stronger chemical exfoliants. Gluconolactone is a PHA, a family of large-molecule acids that penetrates more gradually and superficially than conventional AHAs, resulting in a gentler exfoliating action with a lower risk of irritation. The toner also includes a shield of soothing actives (Aloe, Calendula and Witch Hazel) and moisturising ones (Pentavitin™, Hidroviton™ and NMFs) that counteract any potential sensitising effect. The formula is also silicone-free, fragrance-free and oil-free, vegan and cruelty-free. Despite all this, it is always recommended to carry out a patch test beforehand and introduce the product gradually according to your personal tolerance. In case of irritation, rinse off with plenty of water and, if it persists, stop using it and consult a specialist.
