BIOSSANCE Squalane + Vitamin C Dark Spot Face Serum — 10% Vitamin C, White Shiitake, Fragrance-Free 1.01 fl oz

BIOSSANCE Squalane + Vitamin C Dark Spot Face Serum is a lightweight, fragrance-free daily serum that combines 10% vitamin C, white shiitake extract, and squalane to visibly brighten skin and target dark spots without irritation.

This serum blends a stabilized form of vitamin C with botanical brighteners and weightless squalane to help even skin tone while delivering hydration. Formulated without added fragrance and designed for sensitive to resilient skin, it absorbs quickly, layers easily under moisturizers and sunscreens, and is suitable for everyday morning or evening use. The 1.01 fl oz bottle gives a compact supply for a consistent targeted routine.

How does this serum help reduce dark spots and uneven tone?

The formula pairs 10% vitamin C with white shiitake mushroom extract to support a more uniform complexion and a brighter surface appearance. Vitamin C works as an antioxidant-stable brightening ingredient, while botanical extracts help complement its action and support skin clarity over repeated use.

• 10% vitamin C concentration aimed at visible brightness improvement
• White shiitake extract to support even tone and luminosity
• Squalane to maintain hydration while active ingredients work
• Fragrance-free to reduce risk of irritation for sensitive skin

Is this serum suitable for sensitive or reactive skin?

BIOSSANCE designed this product with gentle daily wear in mind: it’s fragrance-free and formulated to minimize stinging or irritation commonly associated with stronger treatments. Because every complexion reacts differently, patch testing is recommended before full-face application, especially if your skin is very reactive.

• Fragrance-free formula lowers potential irritation
• Weightless squalane supports the skin barrier for comfort
• Recommended patch test before first full application
• Appropriate for all skin types when used as directed

How do I incorporate it into my daily routine for best results?

Apply two to three pumps to cleansed face and neck, morning or evening. Let it absorb fully before layering moisturizer and sunscreen in the day; nightly use works well too. Consistent, daily application yields the most noticeable improvements over weeks.

• Use 2–3 pumps per application on cleaned skin
• Allow full absorption before moisturizer or sunscreen
• Can be used morning and/or night depending on your routine
• Expect progressive improvement with consistent use

What can I expect in terms of texture, finish, and compatibility?

The serum has a lightweight, non-greasy texture that sinks into skin quickly, leaving a smooth, hydrated finish. Its squalane base helps maintain moisture while the vitamin C blend targets tone, making it easy to layer under makeup or heavier creams without pilling.

• Light, fast-absorbing texture that layers well
• Squalane delivers weightless hydration and a silky finish
• Compatible with most moisturizers and makeup bases
• Designed to avoid stickiness or residue after application

Who this is for: This serum is aimed at anyone seeking a fragrance-free, hydrating treatment that targets dark spots and uneven tone—especially those who prefer botanical support alongside a clinically relevant vitamin C concentration. It works well for daily users with normal, dry, combination or oily skin, and for sensitive skin types that need gentler brightening options. If you’re building a straightforward, layer-friendly routine to enhance radiance and address discoloration, this BIOSSANCE formula is a practical choice.
