  • We're all on acid... Hyaluronic acid that is

    Hyaluronic acid is one of those ingredients that you see plastered all over product packaging and hear dermatologists wax lyrical about. And with very good reason – there’s pretty much nothing else out there that can help boost moisture levels more than hyaluronic acid.

    Also don’t be put off by the word acid – it’s a common misconception that acids for skin are going to strip and cause irritation, when actually they are key to good to a top notch complexion.

    What is hyaluronic acid?

    Hyaluronic acid (HA) is a natural component of your body’s connective tissue that maintains skin’s strength and elasticity. 50% of it is found in our skin. Everyone sings its praises because it can retain over 1,000 times its weight in water, so it’s super hydrating, and helps to give you a bright appearance by keeping cells plumped and strong.

    As we age, the natural hyaluronic acid levels in our skin decrease. Mostly found in the best anti-ageing beauty products for mature skin and the best moisturiser for dry skin, it’s also a common ingredient in the best night creams. It’s quickly becoming a preventative treatment and skin staple for younger people looking to stave off the effects of ageing for as long as possible.

    Continuous use of HA ensures you retain moisture and elasticity in your skin, which will help if you’re worried about fine lines or dull skin. Hyaluronic acid can also be injected directly, in what’s known as dermal fillers, into the skin to help fill and plump. (N.B., this is very different to botox.)

    Hyaluronic acid serum

    One of the best face serum you should use, hyaluronic acid serums are hero products because of their higher concentration of HA. Each one tends to be a clear, sticky liquid that absorbs super fast and creates a beautiful base for make-up. Because they are so lightweight as well, all skin types will benefit from introducing one into their routines and you can use one in conjunction with another targeted serum.
