Tax excluded. Shipping calculated at checkout
Redness and inflammation don’t stand a chance.
Skin prone to rosacea and persistent redness needs more than just soothing, it needs targeted action. Sérum Erythros works at the source of vascular dilation, helping to reinforce fragile capillaries while minimizing redness and inflammation. This bio-serum is designed to ease visible redness while limiting the formation of new blood vessels, a common trigger for rosacea-prone skin. The goal isn’t just to calm the skin, it’s to help strengthen it over time.
Tested under dermatological control on skins presenting signs of rosacea, this serum offers a precise yet gentle approach to redness relief.
Skin instant:
For sensitive and rosacea-prone skin with diffuse redness, irritation, or visible capillaries. Ideal for those looking to reinforce skin resilience and reduce the appearance of redness long-term.
Benefits:
- Reduces visible redness and irritation
- Strengthens capillaries to help prevent future flare-ups
- Helps regulate vascular dilation and inflammation
- Supports skin’s ability to defend against sensitivity triggers
How to use:
On cleansed skin, apply Sérum Erythros directly to areas of redness. Gently pat with the fingertips until fully absorbed.
Do not rub, let the skin drink it in.
Loshen & Crem’s recommendation:
For best results, use Sérum Erythros as part of a dedicated redness-reducing routine:
1. Prep the skin
Start with a hydrating serum such as Extrait Tissulaires, Amniotique VG, or Colostrum VG if your skin needs extra hydration.
2. Strengthen and soothe
Apply Sérum Erythros directly to affected areas for targeted relief.
3. Lock it in
Follow with Crème Verte Espoir A.R., designed to fortify the skin barrier and reduce inflammation over time.
4. Sun protection is essential
Skin prone to redness is highly reactive to UV exposure. Always finish your morning routine with a SPF to prevent further vascular damage.
