5 Best Hydrating Serums for Dry & Dehydrated Skin

You’ve applied your favourite moisturiser and drunk your 2 litres of water, but your skin still feels tight and dull. Sounds familiar? Dry and dehydrated skin is something we’ve all dealt with. Trust me. I’ve been there!

If your skin is crying out for hydration, adding a serum to your daily skincare routine can help. While dry and dehydrated skin aren’t exactly the same, hydrating serums help to attract and lock in moisture to address both these skin concerns.

Unlike traditional moisturisers, serums have lightweight formulas designed to deliver targeted ingredients to the skin. I’ve spent the last few weeks testing some of the UK’s top-rated formulas - and I’m sharing the ones I think are actually worth your money!

Here are the best hydrating serums that deserve a spot in your daily skincare routine:

Best for a Damaged Skin Barrier: Byoma Hydrating Serum

If you want a product that isn’t just another hyaluronic acid serum, this is for you. This Byoma serum has a milky consistency and is formulated with a soothing blend of ceramides that support your skin barrier. It absorbs into the skin with zero stickiness, leaving your skin looking and feeling soft to the touch.

Kickstart your skincare routine by adding this budget-friendly serum to your cart.

Best Budget Hydrating Serum: Revolution Skin’s Dewy Drench Hydrating Serum

This Revolution Skin serum gives your skin a gorgeous, dewy finish. It absorbed straight into my skin, keeping it feeling plump and fresh all day long. It’s a great option for a simple, low-maintenance routine.

Best for Sensitive Skin: Avene Hydrance Boost Concentrated Hydrating Serum

Avene Hydrance Boost Concentrated Hydrating Serum

I’m no stranger to the Avene brand - and all the products I’ve tried have been amazing at moisturising my skin. The lightweight water-gel consistency makes this serum one of my all-time go-to products from Avene. One of my favourite things about this hydrating serum is that it leaves absolutely zero sticky residue on your skin, which is something I’m always looking for when shopping for a new serum. My skin felt immediately calm and incredibly soft after just the first use.

If your skin needs a little TLC, splurge on this hydration boost serum for the ultimate skincare reset.

Best for Fine Lines: La Roche-Posay Hyalu B5 Serum

This serum feels like 8 hours of deep sleep in a bottle. It’s a richer, more luxurious hyaluronic acid serum than most, melting into the skin, leaving it feeling plump, smooth, and bouncy. This serum is a bit more expensive than others, but I love the glowing, rested look it gives my skin.

Are you starting to think about fine lines? This dermatologist-recommended anti-wrinkle serum is the perfect place to start.

Best Organic Hydrating Serum: Evolve Organic Beauty Hyaluronic Serum 200

Evolve Organic Beauty Hyaluronic Serum

I absolutely love the idea of skincare being handmade in small quantities in the British countryside! It is easily one of my favourite organic hyaluronic acid serums, especially if you prefer a lightweight formula. It gave my skin an instant hydration boost as a serum that feels like pure silk. It’s 99% natural, certified organic, and free from unnecessary or harmful ingredients. A great option for really fussy skincare enthusiasts.
