    My skin looks rested

    After a fortnight my skin looked properly rested in the mornings. Patted into a cleansed face and the routine just clicked.

    Even on sensitive skin

    I have reactive skin and this absorbs without stinging. The post-spot marks I had on my chin look much fainter now after about three weeks.

    Light and effective

    Goes on lightly and never feels sticky. Helps my forehead look more even and less dull, especially after late nights.

    Glow without harsh actives

    A gentle daily routine product. My face just looks healthier and more uniform now. The niacinamide does its job without redness.

    Solid but slow

    Decent serum. It takes a few weeks to see anything obvious. I will keep using it but expect patience rather than instant results.

  • ★★★★★Jonas H.Verified customer

    Quiet and effective

    Lovely thin texture. Layers beautifully under SPF in the morning. My cheeks look brighter without any tingle or shine.

  • ★★★★★Aneliya DimitrovaVerified customer

    Absolutely love this serum! The texture is incredibly gentle and lightweight

    Absolutely love this serum! The texture is incredibly gentle and lightweight, and it feels really pleasant on the skin. It absorbs beautifully without feeling sticky or heavy, and afterwards my skin feels noticeably softer, smoother and well hydrated. I especially love how comfortable and silky my skin feels after using it. Definitely a serum I’ll keep in my routine.
