Take hydration to the next level with Medik8 Hydr8 B5 Intense, a supercharged version of the bestselling Hydr8 B5 serum. While both formulas deliver deep hydration with multi-weight hyaluronic acid and vitamin B5, Hydr8 B5 Intense goes even further. Infused with Natural Moisturising Factors (NMF), Saskatoon berry extract, and an advanced hydration booster, this powerhouse serum locks in moisture, strengthens the skin barrier, and defends against dehydration for longer-lasting results.
Who is it for? If you struggle with persistent dryness, dehydration, or a compromised skin barrier, Hydr8 B5 Intense is your perfect match. Its richer, more advanced formula deeply replenishes moisture while helping to prevent water loss, leaving your skin plump, smooth, and glowing all day long.
For skin that craves lasting hydration, Hydr8 B5 Intense delivers.

Performance Ingredients
Multi-Weight Hyaluronic Acid | With a unique ability to attract and retain more than 1,000 times its own weight in water, hyaluronic acid draws moisture from the lower layers of the skin into the upper 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.
Natural Moisturising Factors (NMFs) | A unique combination of natural components in your skin (sodium PCA, glycerin, urea, proteins, sugars, 15 different amino acids, lactic acid, and creatine) which bind and hold moisture for optimal skin hydration.
Saskatoon Berry | Packed full of wonder-antioxidants called anthocyanins (pronounced ‘ANtho-SYa-nins’), this Canadian superberry can help to block the enzyme which breaks down hyaluronic acid, therefore preserving the skin’s natural moisture levels for visible plumpness.
Soy Extract | A natural and potent antioxidant, soy extract helps to stimulate the skin’s natural production of hyaluronic acid and collagen for hydrated, more youthful-looking skin.

WOW upgraded to the intense B5 and it’s amazing. Goes on so smoothly abs can definitely see a difference. Love it and will buy again
This serum is great for rehydration. Amazing for swimmers to use counteracting the harshness of chlorinated water
Both myself with aging skin and my daughter with young blemish prone skin have seen the difference using this vitamin b, the skin is so well hydrated and looks amazing for us both
This serum is gorgeous! As it says – it is super soft – it glides over the skin & absorbs instantly leaving a “plumped & soft feeling”! I have ageing skin so this serum is ideal for me! I love it !!

I got this in a recent order and it’s made such a difference to my skin dehydration. My fave new hydrating serum
It has some good ingredients for skin care.
I thought it would have more of a quenching feel than I found it to have though.
