Hyaluronic acid serum with vitamin B5
Long-Lasting Hydration Boost | Oil-Free Moisture Replenishment | Plumping & Smoothing Effect
Medik8's original hyaluronic acid serum, and still one of the most reliable hydrators in the range. Hydr8 B5 floods multiple layers of the skin with multi-weight hyaluronic acid, leaving it visibly plumped and supple and softening the look of fine lines.
Vitamin B5 (panthenol) helps the skin hold onto that moisture and supports regeneration, so the effect builds through the day rather than fading by lunchtime. Using several molecular weights of hyaluronic acid is what allows hydration at different depths instead of only on the surface.
The formula is oil-free and absorbs quickly, which makes it a good fit for normal, oily and combination skin as well as dehydrated skin of any type.
It layers neatly under anything, and it is particularly useful alongside a vitamin A routine where dehydration is the limiting factor.
Apply to a cleansed, slightly damp face morning and evening before moisturiser - damp skin gives hyaluronic acid something to draw on.
Hydration is the step most routines under-invest in. Hydr8 B5 goes under your moisturiser morning and night, and it is the product to add if a retinal routine has started to feel uncomfortable before you drop the strength.
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.

Such a great product, hydration with no greasy feel, love it!
Best hydration serum I have ever used. Reccomed medik 8 to everyone!
I have combination skin, which means I typically have a very oily T-Zone and the rest of my face is quite dry. Scouring the internet for a product to help balance out my problem, I came across Medik8 B5 and read other consumers reviews and decided to purchase one for myself. This serum works wonders! I no longer have I a slick shine to my T-Zone and my whole face is nicely moisturised too. The serum is light weight and is quickly absorbs into the skin. I'll be permanently adding this little gem into my skin care routine.
Been using this for a month now and have noticed a massive difference in my skin! So much more hydrated and plump!
Since i have started using it, my skin looks alive. I feel that the fine lines have been reduced and feels more hydrated. So lucky i discovered this product.
