A 30-Second Step That Changes Your Whole Routine

Your questions, answered
Building confidence with clear answers to your concerns.
How often should I use the PDRN Pink Peptide Serum?
For best results, use it twice daily — once in the morning and once in the evening — as part of your cleanse-tone-treat-moisturise routine. Consistent, twice-daily use is what drives the visible firming and brightening results over a fortnight.
Is this serum suitable for sensitive skin?
Yes — the formula is designed with skin tolerance in mind and is free from common irritants. That said, if your skin is particularly reactive, we recommend doing a patch test on the inner arm for 24 hours before applying to your face.
What does PDRN actually do for skin?
PDRN (Polydeoxyribonucleotide) is a skin-repair active derived from salmon DNA that helps promote the skin's natural cellular recovery process. It's widely used in professional skincare settings and is valued for its ability to reduce the appearance of fine lines and improve overall skin texture over time.
How does it feel on the skin?
The texture is silky and water-light — it absorbs within seconds and leaves no greasy residue. Most users describe the finish as a smooth, comfortable second skin that sits well under makeup or SPF.
When can I expect to see results?
Many users notice an improvement in skin hydration and radiance within the first week. For firming and fine-line reduction, the more meaningful changes typically become visible after a consistent fortnight of twice-daily use.
How do I layer this serum with other products?
Apply the serum after your toner and before your moisturiser — this allows the actives to penetrate unimpeded. If you're using other actives like a vitamin C serum, apply the lighter, more watery formula first and allow each layer to absorb fully before the next.
What skin concerns is this serum best suited for?
It's particularly well-suited for anyone dealing with loss of firmness, fine lines, dull or uneven skin tone, or a compromised skin barrier. It works well for mature skin as well as younger skin looking to maintain elasticity and radiance.
Can I use this serum both morning and night?
Absolutely — the formula is gentle enough for twice-daily use. In the morning, follow it with a broad-spectrum SPF to protect the skin while the actives do their work. In the evening, layering it under a richer night cream can help maximise overnight recovery.
Loved by our customers
Real feedback from real customers.
I was sceptical about the PDRN ingredient at first, but after a fortnight my fine lines around my eyes look softer and my skin tone is more even. It layers beautifully under my moisturiser without pilling. 🙌
Really lovely lightweight serum — it disappears into the skin within seconds. I haven't seen dramatic firming yet but the brightness boost was noticeable from the first few days of use.
My skin has that "lit from within" look I've been chasing for ages. I apply two drops at night and wake up to skin that looks rested and dewy rather than dull.
The scent is very subtle and clean, which I appreciated because fragrance usually irritates my skin. After consistent use for a couple of weeks my cheeks feel noticeably firmer when I press them — not placebo, genuinely firmer.
Good serum, great price for what you're getting in terms of K-beauty actives. My skin tone has evened out and my pores look smaller, though I'll need another bottle before I can properly judge the firming claim.
I have combination skin that reacts badly to heavy serums and this one gave me zero breakouts. The pinkish colour is cute and the formula feels almost gel-like — it sits perfectly under my SPF every morning.
Solid serum that's earned a permanent spot in my routine. The hydration is real and immediate, and my makeup sits so much better on days I've used it. Would love a slightly bigger bottle for the price.
I bought this on a whim and it's turned into my most-used skincare product. After about ten days I started getting compliments on my skin looking glowy — the peptide combination clearly works well together.
