Beauty enthusiasts have only hours left to secure a 30% discount on a Korean skincare serum that combines three of the beauty industry's biggest buzzwords for 2026. The haruharu wonder Rose PDRN Firming Serum with Retinal, normally priced at £19, has been reduced to £13.30 as part of Amazon's Prime Day sale, which ends at midnight tonight.
What Makes the Serum Unique?
K-beauty has surged in popularity, driven by social media and formulations that feature restorative, hydrating ingredients delivering visible results. Key ingredients gaining traction this year include rejuvenating PDRN and anti-ageing retinal. The haruharu wonder serum packages both into one discounted product. Launched in January 2026, it is uncommon to see a beauty product discounted so soon after debut, making this an ideal opportunity to try it at 30% off.
PDRN is typically linked with injectable treatments in aesthetic clinics, often derived from salmon sperm, but haruharu wonder uses a vegan substitute. The serum's vegan Rose PDRN helps revive lacklustre skin, even out rough texture, and promote a naturally glowing complexion. Retinal, considered by many skincare specialists as the next level up from retinol, is included at 0.1% concentration to smooth rough areas, diminish visible lines, and encourage a refined, luminous appearance without being too harsh for sensitive skin.
Customer Reviews and Feedback
The serum has achieved a 4.5-star rating from Amazon customers over the past six months. One shopper, who found their previous skincare regime aggravated their skin, said: 'I bought this and used it every night for 2-3 weeks. My face is back to being nice and plump - no breakouts either. I was always super satisfied with Korean skincare and this one didn't disappoint.'
Another customer who had 'tried multiple retinol products' and 'hated every' one of them said: 'I decided to give haruharu wonder rose PDRN firming serum a shot. I am so glad I did. This PDRN retinal combo hits all the marks for me. This stuff is so gentle, light, and feels like a dream when applied. Soaks in immediately, no pilling, no stained pillow cases, no greasy feeling, just a nice satin finish. I use it nearly every night, and there has not been a single flake or dry patch, just clear, even glowing skin. In case you couldn't tell, I am in love, and this will be my ultimate holy grail, beautiful skin bestie.'
However, some customers noted that the product left yellow marks on their bedding due to retinal's naturally golden hue. A five-star review read: 'It goes on so nicely and feels more gentle than normal retinol. I wake up with glowing skin. I'm in my mid-40s, and people often think I'm in my late 20s-early 30s when they meet me and are shocked when they find out my real age. I use this on all the days I'm not using a stronger retinol 3x/week.'
Additional Benefits and Alternatives
Clinically proven to enhance firmness, texture, and radiance, the serum incorporates haruharu wonder's patented Phyto-Velvet Network for a feather-light, non-tacky finish. A 5-peptide complex works to improve elasticity, increase skin smoothness, and refine overall tone. Formulated for evening application due to retinal, the serum is designed for nightly use.
At LookFantastic, the INNISFREE Retinol Green Tea PDRN Firming Serum 25ml is reduced to £24.80 (down from £31), featuring retinol rather than retinal. Medik8's Exo-PDRN Prismatic+, priced at £79, uses vegan PDRN without retinal but can be paired with the brand's Crystal Retinal.
haruharu wonder also offers other skincare products on Amazon, such as the Black Rice Moisture Airyfit Daily Sunscreen SPF50+/PA++++ (now £11.52, down from £17) and the Black Rice Bakuchiol Eye Cream (now £9.45, down from £13.27).
