BIOSSANCE Squalane + Lactic Acid Resurfacing Night Serum — 1.0 oz, 10% Vegan Lactic Acid & Hydrating Squalane

BIOSSANCE Squalane + Lactic Acid Resurfacing Night Serum is a 1.0 oz overnight treatment combining 10% vegan lactic acid with squalane to smooth texture, reduce fine lines, and support environmental defense.

This lightweight night serum blends a clinically effective 10% vegan lactic acid with BIOSSANCE’s hydration-first squalane base and a clover extract to help renew skin texture while minimizing irritation. Formulated for nightly use, it dissolves dead skin cells and promotes cell turnover for a visibly smoother, more radiant complexion. The formula is vegan and designed to be used across face, neck, and décolleté as part of an evening routine.

How quickly will I see smoother, more radiant skin?

Many users notice improved texture and brightness within days, with more pronounced smoothing and reduced fine lines within one to two weeks of consistent nightly use. Results depend on skin sensitivity and prior exfoliation habits.

• 10% vegan lactic acid helps accelerate surface cell turnover.
• Visible smoothing and refined texture in as little as one week for some users.
• Use nightly for incremental improvement without over-stripping.
• Apply to face, neck, and décolleté for even results.

Is this serum safe for nightly application on sensitive skin?

The formula is designed to be gentle while delivering a potent 10% lactic acid concentration buffered in a squalane-rich base to reduce irritation. If you have very reactive skin, start every other night and build tolerance; discontinue if persistent irritation occurs.

• Squalane hydrates and helps maintain skin barrier integrity.
• Begin with 2–3 pumps and spread evenly; decrease frequency if needed.
• Patch test before full-face use to assess sensitivity.
• Pair with calming moisturizers like Squalane + Omega Repair Cream for barrier support.

How does this serum protect skin from environmental stressors?

Alongside exfoliation, the serum contains clover extract that supports defense against daily aggressors such as pollution and blue light, helping preserve skin’s appearance. The combination of resurfacing acid and barrier-supporting squalane enhances resilience to external stress without drying the skin.

• Clover extract contributes antioxidant support against environmental damage.
• Squalane helps reinforce the skin’s natural moisture barrier.
• Regular use reduces texture irregularities that make skin look aged by stress.
• Follow with a nighttime moisturizer for added protection and hydration.

How should I incorporate this into my evening routine?

Apply 2–3 pumps of the serum to clean, dry skin each night, gently massaging it across face, neck, and décolleté. For best results, follow with Squalane + Marine Algae Eye Cream and finish with Squalane + Omega Repair Cream to lock in moisture and support recovery while you sleep.

• Use on freshly cleansed skin to maximize exfoliation and absorption.
• Start with every other night if new to acids, then progress to nightly as tolerated.
• Always follow with moisturizer to soothe and hydrate the skin barrier.
• Use daily sunscreen in the morning—exfoliation can increase sun sensitivity.

Who is this for: This serum is suited for people aiming to improve skin texture, minimize fine lines, and brighten dull complexions without heavy physical exfoliation. It works well for those comfortable using an acid-based night treatment—especially anyone seeking a vegan lactic acid formula paired with hydrating squalane. If you have extremely sensitive or compromised skin, consult a dermatologist or start with reduced frequency and patch testing.
