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

Biossance Squalane + Vitamin C Dark Spot Face Serum is a lightweight, fragrance-free treatment that combines 10% stabilized vitamin C, white shiitake extract, and squalane to hydrate skin and help even skin tone without irritation.

This serum pairs a clinically minded concentration of vitamin C with plant-derived support ingredients to target uneven pigmentation while keeping the skin barrier nourished. The formula is designed for daily use across skin types, including sensitive skin, and absorbs quickly so it layers well under moisturizers and sunscreens.

How does this serum help reduce the appearance of dark spots?

The 10% vitamin C works as a brightening antioxidant that targets areas of hyperpigmentation, while white shiitake mushroom extract supports a more uniform tone. Together they help minimize the look of discoloration over continued use without harsh exfoliation.

• 10% stabilized vitamin C for consistent brightening benefits
• White shiitake extract to support even tone
• Gentle formulation suitable for repeated daily application

Will this serum hydrate my skin without feeling heavy?

Squalane is the primary hydrator in the formula; it provides lightweight, non-greasy moisture that reinforces the skin barrier. The serum feels silky and sinks in quickly, making it suitable for morning or evening routines.

• Plant-derived squalane for weightless hydration
• Fast-absorbing texture that layers smoothly under products
• No heavy residue, ideal for combination or oily skin

Is this safe for sensitive or fragrance-sensitive skin?

The serum is fragrance-free and formulated to minimize irritation while delivering active ingredients. Because it uses a balanced concentration of vitamin C and supportive botanicals, many sensitive skin types can incorporate it, though patch testing is recommended.

• Fragrance-free formula to reduce sensitization risk
• Non-irritating emollients to soothe and protect skin barrier
• Suitable for daily use with standard patch-test precautions

How should I use the serum in my routine for best results?

Apply two to three pumps to clean, dry skin on face and neck, then follow with moisturizer and sunscreen in the morning. It can be used morning or night, and its lightweight nature makes it easy to layer with other treatments.

• Use 2–3 pumps on cleansed face and neck
• Layer under moisturizer; always follow with SPF in daytime
• Consistent daily use yields most noticeable improvements

Who is this for: This serum is aimed at anyone who wants to brighten and even skin tone without strong fragrances or heavy textures — ideal for people with dullness, early hyperpigmentation, or those seeking daily antioxidant support. It fits well into minimalist skincare regimens and is formulated to be gentle enough for many sensitive skin types, while still delivering a meaningful vitamin C concentration for visible radiance.
