PDRN Brightening Serum
Results don't happen overnight. But they do HAPPEN
How long till my
skin glows?
Hyaluronic acid works immediately — skin feels plumper and more comfortable from the very first application.
Rough patches start to smooth. Skin surface feels more even under fingertips.
PDRN's cell renewal signals start showing. Dullness visibly reduces. This is when most users first notice the difference.
Consistent use delivers cumulative results — skin tone evens out, expression lines appear visibly softer.

Experts love us too.
Trust + Transformation — I don't endorse products lightly. But when I see my patients' skin transform in weeks, the science speaks for itself.
Four actives. Zero fillers.
BACKROOM's formula is deliberately minimal — every ingredient has a precise job. This is what clinic-grade looks like in a $35 serum.
Polydeoxyribonucleotide
DNA-derived molecule originally used in Korean dermatology clinics for skin regeneration. Binds to A2A adenosine receptors — triggering the skin's natural repair response. Visibly reduces dullness and uneven tone over 2–4 weeks.
Acetyl Hexapeptide-8
Interrupts the neuromuscular signal that causes expression lines. Clinical studies show measurable reduction in wrinkle depth with consistent use. Often called "topical Botox" — though more accurately: a targeted peptide that works from within.
Sodium Hyaluronate
Low molecular weight form of HA that penetrates deeper than standard hyaluronic acid. Binds up to 1000x its weight in water at multiple skin depths — delivering sustained plumpness without heaviness or residue.
Panthenol (Pro-B5)
Converts to pantothenic acid in skin, feeding the cells that build and maintain your protective barrier. Anti-inflammatory, barrier-reinforcing, and deeply softening — the ingredient that makes everything else work better.
Sodium PCA
A natural moisturising factor your skin already produces — replenishing it from outside boosts the skin's own ability to hold water all day, without needing repeat application.
Glycerin + Propanediol
A weightless, alcohol-free solvent pair that gives the serum its instantly-absorbing, non-tacky texture. Draws moisture to the surface while helping every active ingredient penetrate cleanly.
GLOWING SKIN MADE EASY
Three Steps to Radiant Skin
1. Cleanse
Start with clean, dry skin. Gently cleanse your face to remove impurities and prep your skin for maximum absorption.
2. Apply
Apply 2-3 drops of PDRN Brightening Serum evenly across your face and neck. Gently press into skin using your fingertips.
3. Protect
Follow with your moisturizer and SPF during the day to lock in radiance and keep your glow protected.
4. Glow
Enjoy your radiant, glowing skin. Use daily for best results and watch your complexion transform.

Everything you need to know.
What is PDRN and why does it matter?
PDRN (Polydeoxyribonucleotide) is a bioactive molecule derived from salmon DNA, used in clinical aesthetic medicine for wound healing and skin regeneration. Applied topically, it activates fibroblast activity — the cells responsible for collagen, elastin, and overall skin renewal. It's what separates this from a standard brightening serum.
Answered by BACKROOM Science Team
Is this suitable for sensitive skin?
Yes. The formula is dermatologist-tested and certified low-irritation. It contains no alcohol, no fragrance, no parabens, and no silicones — the most common irritants. The pH of 5.8–7.8 is calibrated to stay within your skin's natural comfort zone.
Answered by BACKROOM Science Team
When will I see results?
Most users report visible changes in clarity and texture within 2 weeks of twice-daily use. PDRN works progressively — the longer and more consistently you use it, the deeper the results.
Answered by BACKROOM Science Team
Can I use this with my other skincare products?
Yes. Apply after cleansing and before moisturiser. It layers well with most actives. If you're using a strong retinol or AHA, introduce BACKROOM gradually and listen to your skin.
Answered by BACKROOM Science Team
How long does one bottle last?
At the recommended 2–4 pumps twice daily, a 30ml bottle lasts approximately 4–6 weeks depending on usage. Enough time to see and feel the difference before deciding on your next order.
Answered by BACKROOM Science Team
What exactly is PDRN and how does it work on skin?
PDRN is polydeoxyribonucleotide — fragments of DNA (most often salmon-derived) that bind to A2A adenosine receptors in your skin. This triggers the skin's natural repair pathways: stimulating fibroblast activity, collagen synthesis, and cell regeneration. Think of it as a biological signal your skin already understands.
Answered by BACKROOM Science Team
Can I use this alongside retinol or vitamin C?
Yes — PDRN is actually known to reduce irritation caused by stronger actives like retinol. Apply BACKROOM before your retinol (evening) or after vitamin C (morning). The barrier-supporting Panthenol B5 helps buffer reactive skin. If you're new to actives, introduce one at a time.
Answered by BACKROOM Science Team
How is this different from Medicube or COSRX PDRN serums?
Those are excellent products. BACKROOM's differentiator is the pairing of PDRN with Acetyl Hexapeptide-8 in one lightweight, alcohol-free formula — at a price point well below comparable dual-active serums. You get the regenerative benefit of PDRN plus peptide-targeted line softening in a single step.
Answered by BACKROOM Science Team
I have fish allergies — is PDRN safe for me?
This is a legitimate question. PDRN in our formula undergoes extensive purification — the protein components (which cause allergic reactions) are removed during processing. However, we always recommend a patch test first, and if you have severe fish allergies, consult your dermatologist before use.
Answered by BACKROOM Science Team
Does this replace my moisturizer?
No. This is a treatment serum, not a moisturizer. Apply it after cleansing and toning, then follow with your regular moisturizer. The serum delivers active ingredients deep into the skin, while your moisturizer seals in hydration and protects the skin barrier.
