Biotherm Blue Therapy Blue Retinol Night Serum 30ml

The Biotherm Blue Therapy Blue Retinol Night Serum is a targeted overnight treatment designed to work with your skin’s natural renewal cycle while you sleep. Part of Biotherm’s well-regarded Blue Therapy collection, this 30ml serum harnesses the power of Blue Retinol — a retinol complex developed to deliver visible results whilst being mindful of skin sensitivity.

This serum is suited to anyone looking to address the appearance of fine lines, uneven texture, or dullness, and works particularly well as part of a consistent evening skincare routine. The Blue Therapy range is known for drawing on marine-inspired science, and this night serum fits neatly into that philosophy of supporting skin’s resilience over time.

At 30ml, it’s a practical size that fits easily into your nightly regime. Apply it after cleansing and toning but before your moisturiser to allow the formula to absorb fully. Whether you’re new to retinol or looking to step up your evening routine, this Biotherm serum is a considered choice for smoother, more refreshed-looking skin come morning.
