BIOSSANCE Squalane + Lactic Acid Night Serum — 10% Lactic Acid, 1 oz Hydrating Resurfacing Exfoliant for Texture & Fine Lines

Biossance Squalane + Lactic Acid Resurfacing Night Serum is a lightweight, vegan night exfoliant that combines 10% lactic acid with squalane to refine texture, hydrate, and improve the appearance of fine lines.

This concentrated evening serum pairs a potent, plant-based lactic acid with Biossance’s signature squalane to dissolve dead skin cells while replenishing moisture. Designed to be gentle enough for nightly use, it targets uneven texture, visible pores, and early signs of aging without over-drying, and includes botanical extracts to support the skin’s barrier against environmental stressors.

How does this serum refine texture without causing dryness?

The formula uses 10% vegan lactic acid, an alpha-hydroxy acid that promotes cell turnover by loosening bonds between dead skin cells. Instead of stripping oils, it’s combined with squalane to support skin lipids and prevent the tight, dehydrated feeling often associated with exfoliants. Regular use helps reveal smoother, more even skin while maintaining comfort.

• 10% vegan lactic acid for chemical exfoliation
• Squalane to restore hydration and skin lipids
• Non-stripping texture suitable for nightly application

Will this reduce the look of fine lines and enlarged pores?

By accelerating skin cell turnover, lactic acid helps to soften the appearance of fine lines and encourages a more refined surface, which can make pores look smaller. Visible improvements in texture and radiance are often noticed within one to two weeks when used consistently as directed. Results depend on individual skin type and routine.

• Targets surface texture to visibly smooth lines
• Improves skin radiance for a fresher appearance
• Can help pores appear less prominent with regular use

How should I add this serum to my nightly routine?

Apply 2–3 pumps to clean, dry skin in the evening, gently massaging over face, neck, and décolleté. Follow with a hydrating eye cream and a richer night moisturizer to lock in moisture. Because this is an active exfoliant, always use daytime sun protection while using the product to protect fresh skin cells.

• Massage 2–3 pumps into face, neck, and décolleté at night
• Pair with squalane-rich moisturizers for balanced hydration
• Use broad-spectrum SPF during daytime while using actives

What extra protection does the formula offer against daily aggressors?

The serum contains botanical extracts that support the skin’s natural defenses, helping it better tolerate environmental stressors like pollution and blue light. These supporting ingredients work alongside exfoliation and hydration to maintain a healthier barrier. While helpful, this is complementary protection and not a replacement for sunscreen or other protective measures.

• Botanical extracts to reinforce barrier resilience
• Supports defense versus daily environmental stress
• Acts as a complement to, not a substitute for, SPF

Who is this for? This serum is formulated for people seeking a gentle yet effective nightly exfoliant to improve skin texture, reduce the appearance of fine lines, and boost radiance. It suits most skin types that tolerate active acids, especially those wanting a hydrating alternative to harsher exfoliants. If you have severely sensitive or reactive skin, patch testing or consulting a skincare professional is recommended before nightly use.
