About the product

Sérum Yall~O2 is the radiance serum. It combines Biologique Recherche's own oxygenating complex with hyaluronic acid, marine collagen and pomegranate, hibiscus and lily extracts. The idea is simple: hydrate the skin and help it breathe better, especially in the city.

The texture is silky and very pleasant, melts in within seconds and leaves a fresh, shine-free finish. You notice it in the tone: the grey cast of tiredness, pollution or too little sleep gives way to colour and freshness.

It is a finishing serum that gets along with everything, and one of our favourites for urban skin.

What it does

  • Hydrates and refreshes instantly
  • Brings colour back to grey, tired skin
  • Silky, shine-free finish
  • Antioxidants against urban pollution

How to use

  1. Morning and/or evening, after Lotion P50 and targeted serums.
  2. A few drops on face, neck and décolleté, before cream or on its own in summer.

Frequently asked questions

Is this a genuine product?

Yes. Everything in the shop comes from the official Biologique Recherche distributor in Spain — the same stock our aestheticians use in the treatment room at Avenida Diagonal 369.

When will it arrive?

We ship within 24 hours on working days and delivery takes 1–2 working days in mainland Spain. Shipping is free from €100; below that it's €4.90. You can also collect it for free at the centre.

Can I return it?

Yes, within 14 days of delivery as long as the product is unopened and the seal is intact. For hygiene reasons opened cosmetics can't be returned, unless they arrived damaged or wrong — then we sort it out at our cost.

Is it right for my skin?

Not sure? Write to us on WhatsApp with a photo of what you're using now and one of our aestheticians will tell you whether this product fits your routine — or what to use instead.

How do I pay?

By card (Visa, Mastercard), Apple Pay, Google Pay or Revolut Pay. Payment is processed by Revolut with full encryption; we never see your card details.
