Product Description

Achieve a deeply hydrated complexion with Medik8’s original hyaluronic acid serum.

Working to flood the skin with moisture, Hydr8 B5 infuses multiple layers of the skin with multi-weight hyaluronic acid to leave it visibly supple and plump, while softening the appearance of fine lines.

Improving the skin’s ability to retain moisture, it leaves the complexion feeling intensely hydrated, cushion-soft and visibly replenished. Lightweight and oil-free, it quickly absorbs into the skin for fast visible results without any greasiness.

Key Benefits:
Long-Lasting Hydration Boost
Immediately floods the skin with moisture and boosts its natural moisture retention and regeneration abilities for long-lasting hydration.

Plumping & Smoothing Effect
Effortlessly smooths the appearance of fine lines and wrinkles while promoting a more supple-looking, plumper complexion.

Oil-Free Moisture Replenishment
This lightweight formula leaves skin replenished without clogging your pores. Ideal for normal to sensitive skin types.

Key Ingredients:
Multi-Weight Hyaluronic Acid
Unlike other hyaluronic acid serums available, Hydr8 B5 features multiple molecular weights of hyaluronic acid (small, medium and large), to evenly distribute deep hydration throughout the many layers of the skin - leaving it visibly supple and nourished.

Vitamin B5
Helps the skin to retain moisture and supports skin cell regeneration for a visibly plumper complexion.

Rated 4 out of 5 by from Lightweight serum that soaks into [This review was collected as part of a promotion.] Lightweight serum that soaks into my skin well. I haven't seen results yet but I'm only half way through the bottle.

Rated 5 out of 5 by from Recommended by My Skin Therapist – Now a Staple [This review was collected as part of a promotion.] ★★★★★ I’ve been using Medik8 Hydr8 B5 on my dehydrated 36-year-old skin after it was recommended by my skin therapist, and I absolutely love it. The serum feels lightweight and sinks in beautifully without leaving any sticky residue. My skin feels noticeably more hydrated, plumper and comfortable throughout the day, and it layers perfectly under the rest of my skincare and makeup. A little goes a long way, and my skin always looks healthier and more refreshed when I use it consistently. It’s now a staple in my routine, and I can definitely see why my skin therapist recommended it. Highly recommended for anyone struggling with dehydrated skin.
