Serum Erythros in detail 🔎

Longer description

Serum Erythros is a targeted treatment developed specifically for skin affected by chronic redness, rosacea, and visible capillaries. Combining seven synergistic active ingredients, this formula works beneath the surface to address the vascular reactivity and inflammatory responses that drive redness-prone skin.

At the heart of the formula are botanical extracts and anti-inflammatory agents that help limit the dilation of blood vessels and reduce the formation of new micro-capillaries. Rather than masking redness, Sérum Erythros works with the skin to minimise the biological triggers of couperosis—such as heat sensitivity, stress, and micro-inflammation.

With regular use, the serum calms visible redness, reinforces capillary walls, and helps the skin respond more evenly to external aggressors like temperature changes and pollution. Its lightweight, fast-absorbing texture makes it easy to integrate into any sensitive skin routine.

Ideal as a daily support serum for sensitive, reactive, or rosacea-prone skin, Serum Erythros offers not only visual improvement but also functional resilience—bringing the skin back into balance.

Skin science

Couperosis, also referred to as rosacea, is a skin disease which takes the form of redness primarily affecting the nose, cheeks, forehead and chin. The most common is erythematotelangiectatic rosacea, defined by vascularization disorders associated with cutaneous inflammation. It manifests itself in redness and visible blood vessels in the form of a spider’s web.

How to use Serum Erythros

On cleansed skin, apply a few drops of serum morning and/or evening to the areas that are afflicted by rosacea. Do not rub.
