Amazon Prime Day Deal on Popular Korean Skincare Serum
The haruharu wonder Rose PDRN Firming Serum with Retinal, typically priced at £19, has been reduced to £13.30 during Amazon Prime Day. This serum combines three of the beauty industry's most talked-about trends for 2026: rejuvenating PDRN, anti-ageing retinal, and rose-based ingredients. Launched in January 2026, the product is already seeing a 30% discount, making it an attractive option for those looking to try a multi-tasking formula.
PDRN, often associated with injectable aesthetic treatments, is derived from salmon sperm in many products, but haruharu wonder uses a vegan alternative. The brand's Vegan Rose PDRN aims to revive dull skin, refine texture, and promote a glowing complexion. The serum also contains 0.1% retinal, which is considered more potent than retinol and works overnight to smooth rough patches, reduce visible lines, and enhance radiance without being overly harsh for sensitive skin.
User Reviews and Results
The serum has earned a 4.5-star rating on Amazon from customers who have tested it over the past six months. One shopper in her mid-40s shared: "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." Another reviewer, who had previously given up on retinol products due to irritation, said: "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."
However, some customers noted that the serum's natural golden hue from retinal can leave yellow marks on bedding. Despite this, many praised its effectiveness for improving skin firmness, texture, and luminosity. The formula includes haruharu wonder's patented Phyto-Velvet Network for a lightweight, non-tacky texture, and a 5-peptide complex to boost suppleness and resilience.
Comparison with Other Products
For those interested in similar products, the INNISFREE Retinol Green Tea PDRN Firming Serum 25ml is available at LookFantastic for £24.80, down from £31, though it uses retinol instead of retinal. Medik8's Exo-PDRN Prismatic+, priced at £79, features a vegan PDRN with enhanced absorption but does not contain retinal. Haruharu wonder also offers other skincare items on Amazon, such as the Black Rice Moisture Airyfit Daily Sunscreen SPF50+/PA++++, reduced from £17 to £11.52, and the Black Rice Bakuchiol Eye Cream, now £9.45 down from £13.27.
While no product guarantees results for everyone, the haruharu wonder Rose PDRN Firming Serum offers a low-cost entry point to explore multiple skincare trends in one formula. As with any retinal product, users new to vitamin A derivatives should patch test and start slowly to avoid sensitivity.
