Biologique Recherche Lotion P50 (150ml for $73 in Sweden, smaller size available)
You open it and it smells of vinegar. You immediately think "what did I get myself into?" But worry not, this product works. Blended with AHA, BHA, PHA, vinegar, Niacinamide and ... Onion extract. The normal P50 is a tad strong for my skin, but it is manageable. However, I went and bought slightly milder versions: P50V and P50W, to see what's best for my skin.
Biologique Recherche Oligo-Proteines Marines Serum (8ml for EUR28, 30ml for 90EUR)
Yes, BR is expensive, very expensive. This serum is supposed help with pigmentation and can be used under the eyes to help with dark circles. It has the green algae Laminaria Digitata that apparently gets the job done. Well, that’s what the algae promised them. But I honestly did not notice much of an effect. It won’t remove your dark circles, so I am sorry to disappoint you on that. Maybe if used generally on the face, it helps, but I don’t know. I specifically only bought it to test under my eyes.
