An oil-like antioxidant serum derived from French maritime pine bark that helps brighten skin and protect against oxidative stress.

Quick Verdict

A niche antioxidant option for people who want something highly targeted and are already building a thoughtful routine around antioxidants.

ItGirlies Breakdown
Why People Buy This

Pycnogenol is a clinically studied OPC complex with real published evidence behind it — and it remains relatively obscure in consumer skincare compared to vitamin C or niacinamide. The Ordinary is one of the only brands offering it at 5% at an accessible price, making it appealing to informed routine builders who have been aware of the research and waiting for a practical option.

Best Routine Slot

After water-based serums and before moisturizer — morning or evening. If used morning, apply before SPF. The oil-like carrier base means it belongs after water-based steps and before heavier emollients.

Who Will Love This

Skincare enthusiasts who have researched OPC antioxidants, people with redness-prone skin that also deals with dullness, and anyone who has already optimised their vitamin C and wants to explore a complementary antioxidant pathway.

Most Likely to Backfire When…

If you are adding it to an already over-saturated routine just for novelty. Pycnogenol works best as a deliberate antioxidant layer rather than a random add-on to an already complex stack.

If Your Skin Is Already Overwhelmed

The carrier oil base is generally gentle and barrier-friendly. If the full routine needs stripping back, this can be paused without loss — it is a support step, not a structural one.

Pairs Well With
  • Resveratrol 3% + Ferulic Acid 3% on alternating days for rotating antioxidant coverage
  • A vitamin C serum in the same morning routine for multi-pathway antioxidant support
  • SPF 30+ over the top — antioxidants and UV protection work synergistically

Best For

  • Antioxidant support
  • Dull skin
  • Brighter-looking skin
  • Environmental stress support
  • Advanced routines

How to Use

Apply after water-based serums and before moisturizer. Can be used morning or evening. Patch test before full-face use.

Key Ingredients

Pycnogenol 5% (Maritime Pine Bark Extract)

Pycnogenol neutralizes free radicals through its OPC antioxidant complex, inhibits enzymes that degrade collagen and elastin (matrix metalloproteinases), stimulates collagen synthesis, has anti-inflammatory action through NF-κB pathway inhibition, and has been shown in clinical studies to improve skin hydration, elasticity, and the appearance of photoaged skin.

About This Product

The Ordinary Pycnogenol 5% delivers a concentrated dose of Pycnogenol — a standardised extract from the bark of French maritime pine trees (Pinus pinaster) — at 5% in a carrier oil-based format. Pycnogenol is a proprietary OPC (oligomeric proanthocyanidin complex) with strong antioxidant activity, anti-inflammatory properties, and clinical evidence supporting skin hydration, elasticity, and the visible reduction of UV-induced oxidative stress over time. It is a niche antioxidant active — less well-known than vitamin C or resveratrol, but with a compelling body of research behind it. The 5% concentration exceeds most Pycnogenol applications in cosmetic formulations, where 0.5–2% is typical.

Frequently Asked Questions

What does The Ordinary Pycnogenol 5% do for skin?
Pycnogenol provides antioxidant protection against free radical and UV-induced oxidative stress, supports skin elasticity and hydration through collagen-supportive mechanisms, and has documented anti-inflammatory properties that can reduce visible redness and sensitivity over time.
Is Pycnogenol 5% a vitamin C replacement?
No — they work through different antioxidant mechanisms and can be used alongside each other. Vitamin C (L-ascorbic acid or derivatives) addresses melanin synthesis and collagen stimulation more directly. Pycnogenol covers a broader OPC antioxidant pathway and adds anti-inflammatory action. They complement each other more than they replace each other.
Who is most likely to like Pycnogenol 5%?
Advanced routine users with an interest in antioxidant stacking, people dealing with redness or inflammatory skin responses alongside dullness, and skincare enthusiasts who have already covered the basics and want to explore more niche actives.
Can I use Pycnogenol 5% with other antioxidants?
Yes — it layers well with vitamin C, resveratrol, ferulic acid, and vitamin E. Antioxidants generally complement rather than compete with each other, and layering multiple types covers more of the free-radical spectrum.
