Erythrosis, Couperose or Rosacea? When the Skin Becomes Red

Erythrosis, Couperose or Rosacea? When the Skin Becomes Red

Have you ever noticed your face suddenly turning red, perhaps after an intense emotion, a glass of red wine, or a temperature change? In many cases, this is a normal vascular reaction, but when the redness becomes persistent or is accompanied by itching, burning, and a sensation of heat, it may indicate a deeper, chronic condition that requires targeted attention.

According to a study published in the Journal of the European Academy of Dermatology and Venereology, over 50% of European women report sensitive skin prone to frequent redness, and 40% suffer from skin reactivity that interferes with daily life (Misery et al., JEADV, 2018). This data highlights how issues related to facial vascular fragility – such as erythema, couperose, or rosacea – are neither rare nor negligible.

Couperose: persistent capillary dilation

Couperose is characterized by the presence of telangiectasias, that is, dilated capillaries visible on the skin surface, especially on the cheeks and nose. It is more common in people with fair and sensitive skin. Managing couperose includes the use of soothing and protective topical products, as well as specific dermatological treatments such as laser therapy.

Rosacea: a chronic inflammatory condition

Rosacea is a chronic inflammatory skin disease characterized by persistent redness, papules, pustules, and in more advanced cases, skin thickening (rhinophyma). It can also affect the eyes, causing symptoms such as dryness and irritation. It mainly affects adults between 30 and 50 years old and is more common in fair-skinned women.

Treatment strategies for reddened skin: a functional and scientific approach

Erythrosis – Early intervention to prevent

Erythrosis is a functional form of transient vasodilation. Considered reversible, it can predispose to the development of couperose if neglected.

Recommended treatments:

  • Avoid triggers (alcohol, spicy foods, temperature changes)

  • Daily application of topical antioxidants (e.g. sodium ascorbyl phosphate)

  • Hydration with soothing thermal waters (Proksch et al., 2006)

LeLang proposal:

Couperose – Vascular support and anti-inflammatory defense

Recommended actives:

LeLang proposal:

Rosacea – Medical support + high tolerance skincare

Clinical guidelines:

  • Topical drugs: metronidazole, azelaic acid, ivermectin

  • Systemic: doxycycline, isotretinoin

  • Phototherapy: vascular lasers, IPL

  • SPF 50+ sun protection

Recommended skincare:

  • Fragrance-free

  • Film-forming texture

  • Non-comedogenic

LeLang proposal:

  • Nutralight Sensitive (topical use post-medication)

  • Pro Age Thermal Water

  • Elyx cream with organic snail slime


Strengthening the skin barrier is the primary therapy

Many recent studies (e.g., Man et al., J Invest Dermatol, 2015) have shown that epidermal barrier dysfunction is present in both rosacea and couperose. For this reason, it is essential to:

  1. Avoid harsh surfactants
  2. Choose creams with plant ceramides, essential fatty acids, and tolerable protective films
  3. Use thermal waters with minerals that stimulate the production of barrier enzymes (e.g., manganese and copper)

Facial redness is never just an aesthetic issue: it is the sign of a vascular, inflammatory, or barrier imbalance, which invites us to observe more carefully what is happening in our skin.

Distinguishing between erythrosis, couperose, and rosacea is the first step to not underestimate a discomfort that can become chronic and compromise quality of life. Each form of redness has different origins and manifestations, which must be thoroughly understood:

  • The erythrosis warns us of the microcirculation reactivity
  • The couperose indicates a permanent capillary fragility
  • Rosacea is a chronic inflammatory condition that also requires medical support

In this journey, dermocosmetics are not a quick fix, but a daily care tool, if guided by science and tolerability. Sensitive skin should not be “covered,” but listened to, protected, respected.
And this is exactly the direction LeLang’s approach takes: treating the symptom, but also working deeply on skin health, microbiota balance, and natural regeneration of the epidermal barrier.

Choosing products formulated with clinically active thermal waters, soothing plant actives, and functional complexes without fragrance or alcohol is a form of prevention and respect for your skin. You don’t need dozens of steps, but an essential, consistent, and functional routine capable of working in synergy with any medical or dermatological treatments.

📌 Red skin does not ask to be hidden.
It asks to be understood.


FAQ – Frequently asked questions about red and sensitive skin

What are the causes of skin redness?
Redness can result from temperature changes, intense emotions, diet, capillary fragility, skin microbiota dysbiosis, or clinical conditions like couperose or rosacea. Using unsuitable cosmetics can also worsen redness.

What to apply on red skin?
Fragrance-free soothing products with functional ingredients like glycyrrhetinic acid, panthenol, niacinamide, and thermal water. To avoid: perfumes, alcohol, harsh exfoliants.

What is it called when the skin becomes red?
It depends on the cause: erythema (transient redness), couperose (dilated capillaries), rosacea (chronic inflammation with papules/pustules).

What does it mean to have sensitive skin?
It means the skin barrier is compromised and the skin reacts excessively to common stimuli. Symptoms: itching, tingling, burning, tightness, and redness.

How to soothe sensitive skin naturally?
With soothing natural ingredients like chamomile, calendula, mallow, sulfurous thermal water, organic snail slime.

What is the most suitable cream for sensitive skin?
Nutralight Sensitive by LeLang, fragrance-free, with panthenol, hyperthermal water and vegetable butter: recommended during seasonal changes and as a daily treatment.
