Guerniss Alpha-Arbutin Whitening Facial Serum is a lightweight, fast-absorbing formula designed to visibly brighten the skin and improve uneven skin tone. Powered by high-purity Alpha-Arbutin, Niacinamide (Vitamin B3), and Hydrolyzed Pearl, this serum helps fade dark spots, reduce dullness, and enhance overall skin clarity.

Enriched with hydrating and nourishing ingredients such as Sodium Hyaluronate, Panthenol, B-Glucan, and botanical extracts, it deeply moisturizes the skin while supporting a healthy skin barrier. Its smooth, non-greasy texture penetrates quickly, leaving the skin feeling soft, refreshed, and naturally radiant with regular use.

 

1. Brightens & Evens Skin Tone
   Alpha-Arbutin and Niacinamide work to reduce dark spots, hyperpigmentation, and uneven tone by inhibiting melanin production and promoting a more uniform complexion. Alpha-Arbutin is a gentle but effective brightening agent praised by dermatologists for helping fade dark spots and acne scars.
2. Fades Dark Spots & Dullness
   These key actives help visibly lighten stubborn blemishes, pigmentation marks and dull skin over time with consistent use.
3. Deep Hydration & Moisture Support
   Sodium Hyaluronate (a form of hyaluronic acid) attracts and binds water to the skin, giving intense hydration and a plump, smooth look. Similar formulations are known for keeping skin soft and supple.
4. Supports Healthy Skin Barrier
   Panthenol (Vitamin B5) and B-Glucan nourish and help maintain the skin’s protective barrier, reducing irritation and enhancing overall skin resilience.
5. Soothing & Calming Effects
   Botanical extracts alongside Panthenol help calm sensitive or stressed skin, reducing redness and irritation.
6. Lightweight & Fast-Absorbing Texture
   The serum’s non-greasy formula penetrates quickly, making it comfortable for daily use and layering under moisturizer and sunscreen.
7. Leaves Skin Feeling Refreshed & Radiant
   With regular use, skin feels softer, smoother, and appears naturally brighter.

⚠️ Caution for Very Oily/Acne-Prone Skin:

If you’re prone to breakouts, start slowly and patch test (since brightening serums can sometimes irritate acne-prone skin depending on other ingredients in your routine). Always use sunscreen – brightening actives work best and safest with sun protection.
