    Helpful tip to maintain the integrity of the product, Biologique Recherche serums have a uniquely customized applicator that must be manually secured to the bottle. We understand that this could be a bit tricky, especially if you are opening a serum for the first time. We made a handy video to guide you through the process: How To Open Biologique Recherche Serum Vials.

    works but. .

    "FYI IPL (intense pulsed light, or "photofacial") at high power works much better for rosacea!"

    — Emily (3/5)

    Just fine

    "After years of struggling with acne my skin is got very sensitive and I am dealing with a mild redness. I had very high expectations from this serum and I was so excited when I ordered it. It doesn’t calm my mild redness. I don’t feel like it helps my skin."

    — Cristina (3/5)

    So far so good. Redness

    "So far so good. Redness is fading away"

    — Vivian T. (5/5)

    Gradually working

    "I initially seemed to have a reaction to this, which wasn't normal, but it may have been due to external factors. Works fine now but just starting so we will see."

    — Minjia W. (4/5)

    Excellent product

    "I have rosacea and have used several prescriptions. This worked better for me. Will continue to purchase."

    Loving this product line!

    "I am loving the whole Biologique Recherche line. The Serum Erythros has been working for me. I feel that it calms my Rosacea almost immediately after I use it. It doen't seem to be making a long term difference, but if you suffer with this two, you know anything that can actually make a difference is a wonder! This was my first order, but I've already ordered more products to try."

    — Casey W. (5/5)
