Viral K-beauty serum gets a 10/10 from reviewer in £11.90 Medicube deal

A viral K-beauty range has another skincare product attracting attention, with one Medicube customer giving its NAD EGF Firming Serum a glowing 10/10 rating. The reviewer praised its lightweight texture and radiant finish, while saying it absorbed beautifully without leaving behind a tacky feeling.

The Medicube NAD EGF Firming Serum is currently selling fast in a limited-time Amazon deal, with the price reduced to £11.90 from £18.90. That represents a 37 per cent saving, bringing the serum into more affordable territory for anyone curious about the Korean skincare brand.

The customer, who says they are in their early 50s, was particularly impressed by how the Medicube serum felt on their skin. They said it absorbed without leaving a sticky texture and left their complexion looking radiant with a healthy glow.

They also explained that they had been using Medicube products for almost a year and said it was now the only facial skincare brand they use. Their verdict on this particular serum was especially enthusiastic: “10/10.” See the Medicube NAD EGF serum deal

The reviewer was trying the NAD EGF Firming Serum with fine lines in mind, saying they had noticed some small laughter lines and wanted to see whether they could prevent them becoming deeper over time. They described the serum as so lightweight that you barely notice it has been applied.

Medicube's formula is built around NAD+, EGF peptide and collagen, ingredients the brand says are designed to help improve the appearance of wrinkles, firmness and radiance. The Korean skincare serum is also aimed at concerns including rough texture, dullness, loss of elasticity and the appearance of enlarged pores.

The product is designed for both the face and neck, making it an option for anyone who wants to extend their skincare routine beyond the face. Medicube says its NAD+, EGF and collagen complex is intended to nourish the appearance of skin and support a smoother, firmer-looking complexion.

Texture is another selling point. The Medicube face serum has a lightweight, fast-absorbing formula that is intended to provide a plumping and smoothing effect without feeling heavy. That is particularly relevant if you find richer anti-ageing products uncomfortable during the day or underneath other skincare.

The formula is also described as non-comedogenic and dermatologist-tested for skin irritation. However, those claims do not mean the serum will suit every individual complexion, and anyone with particularly reactive skin should introduce new skincare products cautiously.

Medicube has become a recognisable name within the booming K-beauty market, with its range spanning serums, masks, cleansers and other targeted skincare products. The reviewer was similarly enthusiastic about Korean beauty more broadly, saying they felt the industry currently offered strong value compared with high-end brands.

It is worth separating that personal opinion from measurable results, though. The reviewer's 10/10 rating reflects their own experience, while claims around improving wrinkles, firmness and elasticity are product benefits described by Medicube rather than a guarantee that every user will see the same results.

At £11.90, the Medicube NAD EGF Firming Serum is currently £7 below its £18.90 RRP. The deal is marked as selling fast, so the promotional price could change or disappear without notice.

For anyone curious about the viral K-beauty skincare trend, the £11.90 Medicube serum offers a relatively inexpensive way to try one of the brand's targeted firming products, with one particularly enthusiastic customer saying its lightweight feel, glow and approach to fine lines earned it a 10/10.
