Driven by a passion to strive for better skin health and facilitated by a background in physiology, pharmacology and biochemistry, Elliot Isaacs founded Medik8 in order to deliver results-driven formulas, informed by proven science. Firm in the belief that the perfect skin care routine should be simple yet structured, the Medik8 CSA philosophy was coined in 2009; advocating that the pillars of your regimen should include vitamin C and sunscreen by day, and vitamin A by night.
Harnessing the hero ingredients we all know and love (read: hyaluronic acid and panthenol), Medik8's Hydr8 B5 serum is designed to impart a wave of lasting hydration for a plumping and smoothing effect. Here's your ticket to soft, supple skin!
This bestselling formula is crafted with multiple weights of hyaluronic acid - also known as the 'moisture molecule' with its ability to draw and bind moisture to your skin - to ensure the hydration penetrates deep within different layers of your dermis: larger molecules form a veil to continuously feed your upper layers with water and the smaller molecules reach deeper into the skin and draw hydration from the lower layers. What's more, the lightweight yet intensely moisturising serum is also infused with vitamin B5 (a.k.a panthenol) to improve the water retention of your skin, while supporting the natural regenerating process of your cells. As for its other credentials, it's cruelty-free, vegan and free from artificial fragrance and oil. We're obsessed!
After cleansing in the morning and evening, massage 6 drops of Hydr8 B5 across the face, neck and décolletage. Leave to absorb before applying moisturiser.
Please note: the visual and product name listed may differ to the packaging received due to product updates across the range. Rest assured, the formula and great results will remain the same.
Aqua (Water), Panthenol, Sodium Hyaluronate, Calcium Pantothenate, Phenoxyethanol, Ethylhexylglycerin, Citric Acid.

Medik8 does it again
Love the brand, everything I try is great, this one was a surprise and it works well with makeup.Â
Report this reviewSimply the best
I have tried many hyaluronic acid serums and for my skin this is the best. It's not cheap, but it's worth every penny. It has the perfect texture and gives me the hydration I need without being sticky. It's my holy grail and I will keep buying it again and again 💗
Report this reviewHA standard serum
It is a nice serum, but I prefer other HA serums from other brands. It helps with dehydrated skin.Â
Report this reviewGood
Good Hyaluronic Acid serum, like many others. They've also raised the price a bit, so I don't know if I would still recommend it.
Report this reviewGreat basic for skincare routine
I bought this due to good reviews from instagram influencers. I have now bought 3 bottles since as it agrees with my skin and has straightforward ingredients. I also really like the new design on the bottle stopper with the measuring aid.
Report this reviewStill searching for my holy grail HA!
Having only used a cheap, well known brand previously…I searched the net and found this was the most raved about HA serum. Sadly, I cannot see what all the fuss is about. I’ve been using this for months now and I don’t notice a difference when I do or don’t use it in my morning routine. I have combo skin that is dehydrated. It’s a nice silky texture that absorbs well, almost too well. My face feels tacky even when I only use a few drops and not the recommended 6 drops! It doesn’t look plumped or hydrated like others have experienced. It looks dull. For the price tag, I can’t justify repurchasing this no thrills HA and will continue my search!ÂÂ
