Glutathione is widely known as the body's master antioxidant — a naturally occurring tripeptide that plays a critical role in cellular protection and skin brightening. In the Amalys Gluta 5 Days Whitening Booster, we use nano-sized glutathione particles that are significantly smaller than standard glutathione molecules. This nano technology allows the active to penetrate deeper into the skin's layers — reaching the melanocytes where melanin is produced — for enhanced brightening efficacy and faster, more visible and longer-lasting results. Nano Glutathione also provides powerful antioxidant protection against free radical damage caused by UV exposure and environmental stressors, helping to maintain the skin's health, radiance and youthful appearance over time.

Kojic Acid is one of the most effective and well-researched natural brightening actives available. Derived from the fermentation of rice and other fungi, it works by inhibiting tyrosinase — the enzyme responsible for melanin synthesis — to visibly reduce the appearance of dark spots, freckles, acne scars and areas of hyperpigmentation. In the Amalys Gluta 5 Days Whitening Booster, Kojic Acid works in synergy with Nano Glutathione and Alpha Arbutin to deliver a triple brightening effect — targeting melanin production at multiple pathways for faster, more visible and longer-lasting results. Suitable for all skin types including sensitive skin.

Alpha Arbutin is widely regarded as one of the safest and most effective brightening actives available — delivering visible results without the irritation associated with stronger actives. It works by inhibiting tyrosinase activity — the enzyme responsible for melanin production — to gradually and consistently reduce the appearance of dark spots, hyperpigmentation and uneven skin tone. In the Amalys Gluta 5 Days Whitening Booster, Alpha Arbutin completes the triple brightening complex alongside Nano Glutathione and Kojic Acid — delivering a comprehensive, multi-pathway approach to brighter, more even and more radiant skin in as little as 5 days.

Hyaluronic Acid is one of the most effective hydrating actives in skincare — capable of holding up to 1,000 times its weight in water. In the Amalys Gluta 5 Days Whitening Booster, Hyaluronic Acid works by drawing moisture from the environment into the skin and locking it in — ensuring deep, long-lasting hydration that keeps the skin feeling soft, smooth and supple throughout the day. This deep hydration also supports the skin's natural barrier function, enhancing the penetration and efficacy of the brightening actives in the formula. The result is skin that not only looks brighter and more even — but feels beautifully nourished and comfortable with every application.

Vitamin C (Ascorbic Acid) is one of the most researched and proven brightening and antioxidant actives in skincare. In the Amalys Gluta 5 Days Whitening Booster, Vitamin C plays a dual role — it brightens the complexion by inhibiting melanin production and neutralises free radicals caused by UV exposure and environmental pollution, protecting the skin from oxidative stress and premature ageing. Vitamin C also enhances the efficacy of the other brightening actives in the formula — particularly Nano Glutathione and Kojic Acid — creating a powerful synergistic brightening effect. With consistent use, skin appears visibly brighter, more even-toned and radiant with a healthy, natural luminosity.
