The 14 best hydrating serums for moisturised, plump and glowy skin

If you have a problem with transepidermal water loss, then you can’t go past a bottle of this stuff. Formulated with some seriously intelligent ingredients such as panthenol and saskatoon berry, this hydrating serum simultaneously optimises the skin’s absorption of hyaluronic acid and prevents the breakdown of the body’s natural hyaluronic acid stores.

Not only does this award-winning hydrating serum (our Review Crew® members are a big fan) contain trusty hyaluronic acid and panthenol (AKA vitamin B5) but La Roche-Posay Hyalu B5 Hyaluronic Acid Anti-Ageing Serum also contains madecassoside. What is madecassoside, you may be thinking? Well, it’s actually a nifty anti-inflammatory and antioxidant that helps to hydrate skin, as well as relieving the inflammation caused by acne. A great pick for sensitive skin and complexions that have been sensitised due to potent acne serums.

We’re talking about the kind of hyaluronic acid molecules that penetrate deep enough to actually do their job – hydrating skin, plumping fine lines and wrinkles and refining skin tone and texture too.

When you started reading an article about hydrating serums, you probably didn’t think we’d be encouraging you to slather snail mucin on your face. But as far as hydrating skin care ingredients go, our slimy little invertebrate friends are really on to something. In fact, snail mucin (AKA that ooey-gooey stuff snails leave behind them on their travels) is wonderful for hydrating and repairing the skin. If you have particularly sensitive skin, this stuff is great for improving barrier function, soothing irritation, boosting collagen production and improving scarring (the beautiful glow it gives skin certainly doesn’t hurt either). If you’re going to step outside of your comfort zone when it comes to skin care, now would be the time.
