TikTok's latest skincare trend, hyaluronic acid stacking, is all about layering different hyaluronic acid-based products to boost hydration and plumpness for a radiant, youthful glow. But if you're not up for a total skincare revamp, there's one product that offers three levels of hyaluronic acid hydration in a single serum.

The IRÄYE Radiance Firming Serum With Lymphactive, available for £100 here, may be a bit of a splurge when it comes to skincare, but shoppers swear it's worth every penny after claiming it delivers an "instant change" to their skin and saying others asked if they'd had anything done to their face.

IRÄYE 's Radiance Firming Serum gives you three different types of hyaluronic acid in one

The IRÄYE serum is a firming, hydrating and brightening solution packed with three different molecular weights of hyaluronic acid that penetrate deep into your skin, providing intense hydration across multiple layers. It's like a refreshing drink for dry, tight, and tired skin, rejuvenating it completely.

In addition to its ultra-hydrating properties, the serum also actively firms, brightens, and contours your skin, leaving it looking sculpted and smooth. Its ingredients include bio-retinol, which promotes natural collagen and elastin production to minimise fine lines and uneven skin tone, and kakadu plum extract, the world's richest source of vitamin C.

Aiding your skin's lymphatic system to help brighten your complexion and uplift skin function, it also safeguards your skin structure from inflammation and toxins. From your microcirculation to your nutrient intake and immune response, this handy serum boosts everything, giving you that post-facial glow, reports the Mirror.

The serum contains a whole host of active ingredients that hydrate, brighten and sculpt skin

Sure, splashing out £100 on skincare might seem steep, but according to the rave reviews, this serum is well worth the price tag. One happy customer shared, "Been using serum for two weeks, and my husband asked me if I had done something to my face! ! Said absolutely nothing, the only difference to my skincare regime is IRÄYE serum! Love the texture and obviously the results! ".

Another fan of the product exclaimed: "I have noticed an instant change in my skin's health with IRÄYE – it feels much softer, more hydrated and generally more radiant. My skin is oily-dehydrated and it works just as well on my mum's combination-mature skin. No irritation even when my skin is feeling sensitive. An incredible product."

A third shopper penned: "Not only is the product gorgeous and great to see on my countertop, but IRÄYE has results to match. Definitely felt a difference in both hydration and puffiness in my skin, and this is only after 1 week of use. Looking forward to topping up with the refills!"

The serum has gotten rave reviews from shoppers

If you're unsure about committing to a full-sized 30ml bottle, you can try out a mini 15ml bottle for £60 here. This allows you to test the product and see if it suits your skin. Plus, you can purchase refills at a slightly lower price, reducing waste and saving money.

Another hyaluronic acid serum we love is Medik8's HYDR8 B5 Intense, available for £59 here. It promises to rejuvenate tired and dry skin within 24 hours. Packed with superfood antioxidants and Natural Moisturising Factors, it boosts your skin's hydration levels. The formula is soft and non-sticky, leaving your skin feeling silky smooth.

With summer approaching, it's time to up your skin's hydration game, and hyaluronic acid is the way to go.
