A concentrated step for a specific concern
Biotherm Blue Therapy Blue Retinol Night Serum is a facial serum from Biotherm, made for skin that needs a targeted, concentrated step. The formula combines blue retinol and life to support the skin with regular use. It is formulated without parabens, so it suits people who prefer to avoid these in their routine.
How it works
A concentrated fluid or gel applied before the moisturiser, so its actives reach the skin directly rather than sitting on the surface.
Who it suits
- Skin that needs a targeted, concentrated step
- Layering under a daily moisturiser
- Specific concerns like firmness, radiance or ageing
- A routine that already covers cleansing and hydration
Worth knowing before you buy: a serum adds a step to the routine; it works best layered under a moisturiser, not instead of one.
