How Serenvit Retinol Serum works

Serenvit Retinol Serum is BIOSAR's evening renewal serum for the appearance of fine lines, uneven texture, and dullness. Encapsulated Retinol releases gradually overnight to support visible cell turnover; Squalane and Bisabolol soothe the surface so the routine remains tolerable; Vitamin E supports antioxidant defense. Use it as the start of a Retinol routine: twice a week the first month, three times a week the second, then every night as tolerated. Always pair with SPF 50+ every morning. Not recommended during pregnancy or breastfeeding. Pairs with the Serenvit Hyaluronic Acid Serum.

  • Reduced fine lines

    Encapsulated Retinol reduces the look of fine lines with consistent use.

  • Renewed texture

    Gradual release supports visible cell turnover and smoother skin.

  • Eased tolerance

    Squalane and Bisabolol soothe the surface so renewal stays tolerable.

  • Antioxidant support

    Vitamin E supports antioxidant defense alongside the routine.

What to expect

  1. From day one

    Felt on first use

    The light texture absorbs quickly, and the Aloe Vera base helps the skin feel comfortable and hydrated from the first application.

  2. Week 2–6

    First visible improvement

    With consistent use, the quickest-responding concerns show first — hydration, comfort and a more even-looking tone. Texture and firmness take longer.

  3. Week 6–8

    Full targeted result

    Texture and firmness respond last; with consistent use, each serum's focused benefit reaches its full visible effect.

    Results vary from person to person.

Questions about Serenvit Retinol Serum

Why do I need to use the Retinol Serum only at night?

Retinol is photosensitizing — it breaks down under UV and can increase sun sensitivity. Night application paired with SPF 50+ every morning is the standard protocol. Avoid retinoids during pregnancy and breastfeeding.
