It’s a sensation many know well: a sudden jolt of stress, a change in temperature, or a glass of wine, and your cheeks flush in seconds. This phenomenon of sudden, intense redness has a name: facial flushing. When it becomes regular, it is referred to as facial erythrosis.
Far from being a mere aesthetic nuisance, this recurring redness indicates hypersensitivity of the skin's micro-blood vessels. Discover how to decode these reactions and how to soothe them long-term using a natural approach.
What are skin flushing and erythrosis?
A flush is a vasodilation reaction: the small blood vessels in the face suddenly dilate, allowing a large amount of blood to rush to the skin's surface.
Through repeated dilating and contracting, these vessels lose their elasticity. The redness, initially temporary, then sets in permanently in a diffuse manner, particularly on the cheeks and the sides of the nose. This is the stage of erythrosis, which can progress to rosacea (couperose) if the vessels become visible to the naked eye.
The underlying cause: A weakened skin barrier allows temperature fluctuations and external irritants to penetrate, which over-stimulates the skin's vascular system.
How walnut actives strengthen skin prone to redness
To calm erythrosis, it is not enough to mask the red with green makeup. You must treat the root of the problem by strengthening vessel resistance and soothing the skin's nervous system. The walnut proves to be an incredibly effective ingredient:
-
Vitamin E and Polyphenols: These powerful antioxidants protect the walls of the micro-vessels against oxidative stress, limiting their erratic dilation.
-
The anti-inflammatory action of Omega-3: They reduce the inflammation signals sent by the skin during a stimulus (heat, stress), mitigating the intensity of the flush.
-
Barrier protection: By recreating an airtight protective film, Novem skincare products protect the face from thermal aggression (the classic hot-cold effect), the main trigger for redness.
FAQ: Everything you need to know about flushing and facial erythrosis
What is the difference between a flush and rosacea?
A flush is a sudden, temporary redness triggered by a specific factor (emotion, heat). Rosacea is a broader chronic skin condition that encompasses erythrosis (permanent redness) and may be accompanied by small bumps or visible blood vessels (couperose).
Why does stress cause sudden facial redness?
Under stress, the body releases adrenaline and cortisol. These hormones cause an increased heart rate and immediate dilation of the blood vessels in the face, leading to the dreaded flush.
Can diet trigger skin flushing?
Yes, certain foods promote vasodilation. Spicy dishes, very hot drinks, alcohol, and histamine-rich foods (such as aged cheeses or chocolate) are very frequent triggers.
How can you immediately calm a facial flush?
Apply a cool (but not ice-cold, to avoid thermal shock) compress or mist with a soothing floral water. Breathe calmly to lower your blood pressure, then apply a protective Novem skincare product to isolate the skin.
Which cosmetic ingredients should be avoided in cases of erythrosis?
Avoid products containing denatured alcohol, menthol, eucalyptus, or synthetic fragrances, which stimulate blood circulation and irritate the skin. Also avoid abrasive scrubs, which damage the vessels through mechanical action.
