A powerful yet gentle serum designed to brighten dark spots, fade acne marks, and even out your skin tone — this product has become a runaway bestseller in the UK , and for good reason.

🌟 Why It’s a Massive Hit in the UK

UK skincare lovers are increasingly prioritising multi-tasking products that are effective yet gentle enough for sensitive, acne-prone skin. The Axis-Y Dark Spot Correcting Glow Serum checks every box: it's lightweight, fragrance-free, and powered by 5% niacinamide , which dermatologists often recommend for managing acne, pigmentation, and uneven skin tone.

In 2024–2025, as more people turn to Korean skincare for barrier-friendly brightening , this serum has stood out across TikTok, Reddit, and Instagram skincare communities — with UK influencers calling it their “go-to” for fading stubborn pigmentation without the irritation that comes from stronger acids or peels.

It’s especially popular among:

• Those with post-acne scarring looking for fast, visible results

• Skincare minimalists who want results without a 10-step routine

• Sensitive skin types who can’t tolerate harsh brightening actives

At Glow Yeosin , this serum is one of our most reordered products — proof that once customers try it, they don’t go back.

💚 Why Customers Love It

• Lightweight and fast-absorbing – sits beautifully under makeup or sunscreen

• Targets pigmentation and dullness – fades dark spots without causing dryness

• Plant-based formula – includes soothing ingredients like squalane, calendula, and sea buckthorn

• Budget-friendly – high-quality formula without the high price tag

🧴 Best For:

• Uneven skin tone

• Post-inflammatory hyperpigmentation (PIH)

• Dullness or loss of glow

• Acne-prone or sensitive skin

The viral sunscreen that lives up to the hype — and then some. The Beauty of Joseon Relief Sun has become a cult-favourite in the UK , praised not just for its protection, but for how it feels and functions as both a sunscreen and a skincare product.

☀️ Why It’s Huge in the UK

In 2025, UK skincare enthusiasts are prioritising lightweight, non-greasy SPF formulas that offer real protection without compromising their skin’s look or feel. This sunscreen became a favourite almost overnight due to its hydrating texture, zero white cast, and ability to layer under makeup — a true win for all skin tones and types.

It’s frequently recommended in UK-based skincare forums, Instagram reels, and TikToks as the "invisible SPF" that actually nourishes your skin — thanks to ingredients like fermented rice extract and probiotics. Customers love that it doesn’t feel like a sticky, chalky sunscreen… it feels like moisturiser.

At Glow Yeosin , it's consistently in our top 3 most reordered products , especially during spring/summer months when SPF becomes a daily non-negotiable.

💚 Why Customers Love It

• Skincare-meets-sunscreen formula – soothes and hydrates while protecting

• Zero white cast – perfect for all skin tones and especially loved by deeper complexions

• No pilling – works seamlessly under makeup or moisturiser

• Rice + probiotics – nourish the skin barrier and reduce irritation over time

👌 Best For:

• Daily sun protection with skin benefits

• All skin types, including sensitive and acne-prone

• Those who hate traditional, greasy sunscreens

☀️ How to Use:

Apply generously as the last step of your AM routine — after moisturizer and before makeup. Reapply every 2–3 hours when exposed to sunlight for continued protection.

A true icon in the K-beauty world, the COSRX Advanced Snail 96 Mucin Power Essence is more than just a trend — it's a staple in skincare routines across the UK. Packed with 96% snail mucin, this essence is all about hydration, repair, and that radiant glass-skin finish.

🐌 Why It’s a Cult Favourite in the UK

UK skincare enthusiasts have embraced this essence for its ability to calm, plump, and heal the skin — without clogging pores or feeling heavy. It’s particularly popular with those managing acne scarring, uneven texture, or seasonal dryness.

As the popularity of barrier-repairing skincare has soared in 2025, this essence has become a top recommendation from beauty influencers, dermatology TikTok creators, and estheticians across the UK.

🐌 Why It’s So Popular in the UK

With more UK consumers looking for skin-barrier-safe routines , this cream ticks all the right boxes. It’s packed with 92% snail mucin , making it perfect for dry, irritated, or damaged skin , especially post-acne or during seasonal transitions.

Unlike heavy moisturizers that sit on top of the skin, this cream sinks in beautifully , making it ideal for layering in winter and lightweight enough for summer. It pairs perfectly with the COSRX Snail 96 Essence — a duo that many of our customers swear by for total skin transformation.

It’s frequently featured in UK-based skincare routines on TikTok, praised for its “glass skin glow” and ability to calm flare-ups and dryness overnight.

Pro tip: Mix a little with facial oil on especially dry nights for extra nourishment.

If you’re looking for a gentle but effective eye treatment that actually does something, this is the one. The Beauty of Joseon Revive Eye Serum combines time-honoured Korean herbal medicine with modern science to deliver visible results — without irritation. It's become a must-have for UK shoppers looking to prevent or smooth fine lines while brightening the under-eye area.

👁️ Why It’s So Loved in the UK

In the UK, where seasonal weather changes and screen-heavy lifestyles can wreak havoc on the delicate eye area, this serum stands out for its ability to firm, brighten, and refresh . The formula blends ginseng extract (for circulation and nourishment) with retinal — a more potent, stable form of vitamin A that’s known to reduce signs of aging without the harshness of prescription retinoids.

Unlike thick eye creams that can feel heavy or cause milia, this one has a silky, serum-like texture that absorbs quickly and plays well with both day and night routines. It’s also fragrance-free , making it a safe option for sensitive eyes.

Beauty influencers, dermatology TikTokers, and K-beauty fans across the UK have praised it for delivering “bright, rested eyes in a bottle.”

💚 Why Customers Love It

• Retinal (not retinol) – stronger than retinol, but less irritating

• Ginseng root extract – improves circulation + reduces puffiness

• Lightweight texture – sinks in fast and layers beautifully under makeup or SPF

• Brightens and firms – targets dullness, fine lines, and tired-looking under-eyes

✨ Best For:

• Fine lines and early aging signs

• Dark circles and puffiness

• Tired or dehydrated under-eyes

• Sensitive skin that reacts to retinol

🧴 How to Use:

After applying your serums and before your final moisturizer or cream, gently tap a small amount of the eye serum around the orbital bone using your ring finger. Use once daily to start (preferably in the evening), then build up to twice daily if tolerated.

💡 Pro tip: Combine with hydrating toners or essences to support skin resilience while using retinal.
