Cleanse, then apply the Lotion P50 selected for your Skin Instant. If your skin needs extra hydration, prep it with Sérum Extraits Tissulaires, Amniotique VG or Colostrum VG. Apply Sérum Erythros to the areas of redness, then lock it in with Crème V. Espoir. Redness-prone skin is highly reactive to UV exposure, so always finish the morning with sunscreen.

Why it fits


The lightweight hydration serum step for dehydrated, oily or combination skin, applied after cleansing and Lotion P50 and before your moisturizer. It brings water and balance, not richness.

Worth knowing

The finer details.

A closer look at your skin, your routine and what goes into the formula.

Biologique Recherche Sérum Erythros

Biologique Recherche Sérum Erythros is a targeted serum for sensitive, redness-prone skin with diffuse redness, irritation or visible capillaries. Skin prone to persistent redness needs more than soothing: it needs targeted care.

Sérum Erythros helps soothe the skin and reduce the look of diffuse redness and visible capillaries. The goal is not only to calm the skin, but to help it look stronger and more resilient over time. Dermatologically tested, it offers a precise yet gentle approach to visible redness.

Its formula brings together Niacinamide, Arnica Montana Flower Extract, Cypress Seed Extract, Plankton Extract and Green Tea Leaf Extract. It is applied directly to the areas of redness and patted in, never rubbed.

Why we love it

For redness-prone skin, we like a dedicated routine rather than a single product, and Sérum Erythros is its targeted step. We prep the skin with a hydrating serum, apply Erythros directly to the areas of redness, then lock it in with Crème V. Espoir. Because redness-prone skin is highly reactive to UV exposure, we always finish the morning with sunscreen. It is a precise, gentle way to work on the look of redness over time.

Benefits

  • Reduces the look of redness and visible irritation
  • Helps reduce the look of visible capillaries
  • Soothes and comforts reactive skin
  • Helps the skin look more resilient to sensitivity triggers

Best for

Sensitive, redness-prone skin

Pat, don't rub: gentle fingertip pressure lets the serum absorb without adding friction to redness-prone skin.

How to use

  1. Cleanse, then apply the Lotion P50 selected for your Skin Instant.
  2. If your skin needs extra hydration, start with a hydrating serum such as Sérum Extraits Tissulaires, Amniotique VG or Colostrum VG.
  3. Apply Sérum Erythros directly to the areas of redness.
  4. Gently pat with the fingertips until fully absorbed. Do not rub: let the skin drink it in.
  5. Follow with Crème V. Espoir.
  6. In the morning, always finish with sunscreen.

Consultation & reactions

At Loshen & Crem, we want to ensure you have the best possible experience with Biologique Recherche. Before purchasing any Biologique Recherche product, we highly recommend booking a consultation with one of our estheticians. Consultations are available virtually through Google Meet or in person at our Edmonton boutique. An appointment is required.

In the event of a reaction, Biologique Recherche requires photos of the reaction and the product, the lot number found on the product or the bottom of the box, and proof of a consultation with one of our estheticians before they can review the concern.

If you choose to purchase without a consultation and experience a reaction, we will be unable to provide a refund. Our team is always happy to answer your questions and help you select the products best suited to your skin.

ERYTHROS

Such a beautiful product for rosacea prone skin. My skin is much calmer with less redness and irritation.

Must have for redness

I have very sensitive skin that goes red easily. This calms my skin down and I use it everyday!

Works well for clearing redness

I have been using for a couple weeks and noticed a difference immediately. I am very sensitive to most products and have very dry skin. I use this is the Creme Splendid and am loving it.

do not expect to cure rosacea with this

After finishing the bottle I should admit - do not rely on any serum to really cure rosacea and redness. This serum did not really help, my cheeks still get red easily. I wish it was at least hydrating at the same time, but it was not. Maybe it works on capillaries in the long run - but it is not something you can see with your eyes as a result anyways. Not going to repurchase.

stronger capillaries

It works great together with creme espoir on calming down skin with capillaries issues. Very watery, absorbs quickly, smell is not bad, herbal. A few drops is enough for cheeks

Does work on red sensitive cheeks

I experienced really bad cheeks skin sensitivity and the serum hepled. Not too fast but in a month the result is stable. The jar is enough for 4 months usage when using twice daily on 1/2 of the face (cheeks, nose).

Must have for rosacea

This is doing wonders for my face. The redness has dramatically subsided and my pores look tighter. If you're suffering from rosacea, I promise you will see results within weeks.

Perfect for Rosacea

This serum does exactly what it claims to do. Ever since I've started using it, my rosacea has calmed down significantly. It has a very watery texture and has a different dropper compared to other BR serums, so I have to be extra careful when applying it so that I don't lose any product. This along with Masque Biosensible has already done wonders for my redness. Will definitely repurchase!

I love it!

I have sensitive rosacea skin and have been using this serum for a week now with no complaint. I have seen it significantly reduce my redness and have had no irritation from the product (also doesn’t sting)
I highly recommend this product if you have redness you want to calm :)

Maskne Help

Sara recommended this (and a few other products) for hub's maskne. The serum comes in a nice glass dropper which makes it easier to apply. It is actually working to reduce his acne.

Worth the wait.
