Medik8 Hydr8 B5 Serum (Hyaluronic Acid)

Liquid Rehydration Serum

Infuse your skin with long-lasting hydration with Hydr8 B5. Medik8's original hyaluronic acid serum floods multiple layers of the skin with multi-weight hyaluronic acid to leave it visibly plumped and supple, while effortlessly softening the look of fine lines.

Proven to leave the skin feeling more hydrated in 7 days, this lightweight, oil-free serum absorbs quickly for fast visible results that won't leave the complexion feeling greasy.* Instead, it works to improve the skin's moisture retention and regeneration abilities for a cushion-soft, intensely hydrated and visibly replenished complexion.

Key Benefits

  • Long-Lasting Hydration Boost – Immediately floods the skin with moisture while boosting its natural moisture retention and regeneration abilities for even longer-lasting hydration.
  • Oil-Free Moisture Replenishment – This lightweight formula leaves skin replenished without clogging your pores. Ideal for normal to sensitive skin types.
  • Plumping & Smoothing Effect – Effortlessly smooths the look of fine lines and wrinkles while promoting a plumper, more supple-looking complexion.

Proven Results

  • Instantly leaves skin feeling more comfortable*
  • 7 days to leave skin feeling more hydrated*

  • 98% agree formula layered well under makeup*

*Proven via independent consumer study on Hydr8 B5 conducted over 4 weeks on 57 participants.

How to Use

First-time use: If you're new to Hydr8 B5, we recommend a patch test at least 24 hours before first use.

  1. After cleansing in the morning and evening, massage 6 drops of Hydr8 B5 across the face, neck and décolletage.
  2. Leave to absorb before applying moisturiser.

Key Ingredients

  • Multi-Weight Hyaluronic Acid – Unlike many other hyaluronic acid serums, Hydr8 B5 uses multiple molecular weights of hyaluronic acid (small, medium and large), to distribute deep hydration evenly throughout the skin's many layers. This leaves the complexion visibly nourished and supple.
  • Vitamin B5 – Also known as panthenol, vitamin B5 helps the skin to retain moisture, while supporting the regeneration of skin cells for visibly plumper skin.

Using this with microneedling

Microneedling opens channels for a few hours. What you apply afterwards, and when, changes the result.
