Overview

What it is & who it suits

Biossance Squalane + Black Currant Seed Moisture Serum is a lightweight, fast-absorbing face serum formulated to deliver a surge of hydration while helping to reinforce the skin's natural moisture barrier. Built around the brand's signature sugarcane-derived squalane, the formula pairs this skin-identical emollient with black currant seed oil, a nutrient-dense botanical rich in omega fatty acids and antioxidants. Together these ingredients work to soften, smooth, and replenish moisture-starved skin without leaving behind any greasy or heavy residue, making the serum suitable for layering beneath moisturizer or makeup throughout the day and night.

What sets this serum apart in the crowded hydration category is its ability to support the skin's lipid barrier at a deeper level, rather than simply sitting on the surface. Black currant seed oil contributes essential fatty acids that help calm visible redness and improve overall skin resilience, while squalane mimics the skin's own sebum to restore suppleness and reduce the appearance of fine dry lines. The texture is silky and quick to sink in, striking a balance between richness and breathability that works well for combination, dry, or dehydrated skin types, as well as for those living in harsher climates or dealing with seasonal moisture loss.

Biossance formulates this serum with its usual commitment to clean, vegan, and cruelty-free beauty, leaving out parabens, sulfates, phthalates, and other ingredients that can compromise skin health over time. The brand's sugarcane-derived squalane is also an eco-conscious alternative to shark-derived squalene, aligning sustainability with performance. Used consistently, this moisture serum helps skin look plumper, feel more comfortable, and appear visibly nourished, serving as a versatile addition to a daily skincare routine for anyone seeking deep, lasting hydration without complexity or heaviness.
