MEDICUBE PDRN Pink Peptide Serum (30ml)

It works on a few levels:

• Low-molecular hydrolysed collagen (310 Da): Small molecules penetrate more deeply, helping skin feel bouncier and look plumper.
• 13 types of peptides: Help signal the skin to support its natural collagen and elastin production, which improves firmness over time.
• PDRN (salmon-derived): A regenerative ingredient that supports skin repair and renewal, contributing to improved elasticity with repeated use.
• Hyaluronic acid: Deep hydration improves bounce and softens the appearance of fine lines.

The brand's clinical tests report that after a single use, eye wrinkles appear reduced by 9.3% and frown lines by 11.3%.* So you get an immediate plumping effect alongside longer-term firming support.

Clinical testing showed results after a single use:

• Eye wrinkles: reduced by 9.3%
• Frown lines: reduced by 11.3%

Salmon PDRN (polydeoxyribonucleotide, a DNA-derived ingredient sourced from salmon) works by supporting your skin's natural repair processes:

• Boosts cell renewal: encourages faster skin cell turnover and collagen production
• Firms and smooths: supports fibroblasts, the cells responsible for collagen, helping to improve elasticity and soften fine lines
• Strengthens the barrier: increases hydration levels and helps skin feel more resilient and bouncy over time

The main ingredients and what they bring to the formula:

• Salmon PDRN (Sodium DNA): supports skin regeneration, collagen production, and elasticity. The headline ingredient the serum is named for.
• Hydrolysed Collagen and Atelocollagen: hydrate and plump, leaving skin feeling firmer and bouncier.
• Peptides (including Copper Tripeptide-1): signal skin to produce more collagen and elastin, helping to soften fine lines and improve firmness.
• Niacinamide (Vitamin B3): brightens dullness, helps fade pigmentation, and supports the skin barrier.
• Sodium Hyaluronate (a Hyaluronic Acid derivative): draws moisture into the skin for deep hydration and a dewy finish.
• Ubiquinone (Coenzyme Q10): an antioxidant that helps protect against environmental damage and supports elasticity.
• Turmeric, Neem, Holy Basil, and other plant extracts: provide antioxidant and soothing support for a calmer, more even complexion.

Apply it after your toner and essence (if you use one), before moisturiser. A full routine looks like this:

• Essence (optional)
• PDRN Pink Peptide Serum
• Eye cream (optional)
• Moisturiser
• SPF (morning only)

It can be used morning, evening, or both.

Yes. For best results, apply vitamin C first, then follow with this serum.

• AM: Cleanse, vitamin C serum, PDRN serum, moisturiser, SPF
• PM: Cleanse, PDRN serum, moisturiser

If your skin is on the sensitive side, introduce vitamin C gradually (2 to 3 times a week) and keep an eye out for any irritation.

Niacinamide works on a few fronts here:

• Helps even out skin tone and fade the look of dark spots or uneven pigmentation
• Brightens dullness for a more radiant complexion
• Supports the skin barrier, which works well alongside the serum's hydrating ingredients like hyaluronic acid

The formula doesn't contain ingredients typically flagged during pregnancy (retinoids, strong BHAs, benzoyl peroxide, or hydroquinone), and it's designed to be gentle on sensitive skin. That said, the brand hasn't officially certified it as pregnancy-safe. We'd always recommend checking the full ingredient list with your GP, midwife, or obstetrician before use.
