What causes rosacea?

Couperose, often associated with rosacea, is a chronic skin condition characterized by persistent redness and visible small blood vessels on the face. Although it is frequently observed in people with fair skin, its exact causes are still not well understood. However, several factors can contribute to its onset and worsening.

What is the difference between couperose and rosacea?

  • Rosacea: Rosacea is a chronic inflammatory skin condition that primarily affects the face. It manifests with various symptoms, including persistent redness, flushing, papules and pustules (similar to acne), and, in some cases, eye involvement or skin thickening. Rosacea has several forms, each with different characteristics.

  • Couperose: Couperose is one of the symptoms of rosacea, specifically the vascular form. It is characterized by persistent redness and the presence of small dilated blood vessels (telangiectasias) visible on the cheeks, nose, chin, or forehead. Unlike other forms of rosacea, couperose does not include active inflammation with papules or pustules.

What are the symptoms of rosacea and couperose?

Rosacea

The manifestations of rosacea can vary considerably depending on its form:

  • Vascular form: Persistent redness, flushing, and visible dilated blood vessels (couperose).
  • Papulopustular form: Appearance of small red bumps (papules) and pustules that resemble acne.
  • Ocular rosacea: Affects the eyes, causing redness, irritation, burning sensations, and dry eyes.
  • Phymatous (or hypertrophic) form: Thickening of the skin, often on the nose, which can become bulbous (rhinophyma).

Couperose

It specifically concerns diffuse redness and telangiectasias (small dilated blood vessels) that appear on the face. It is not accompanied by papules, pustules, or ocular symptoms observed in other forms of rosacea.

  • Persistent redness: Appears mainly on the cheeks, nose, chin, and forehead. This redness can intensify with temperature changes, alcohol consumption, stress, or sun exposure.
  • Visible small blood vessels: Dilated capillaries, also called telangiectasias, are often visible on the skin's surface, giving a 'red web' appearance.
  • Sensations of heat or burning: The skin may also experience burning or tingling sensations, especially when applying cosmetic products or when exposed to irritating factors.

What are the causes of couperose and rosacea?

The precise cause of rosacea and, by extension, couperose, is not yet clearly established. However, several factors can contribute to its development and the worsening of symptoms:

  1. Genetic Predisposition: Rosacea primarily affects people with fair skin, suggesting a genetic component.
  2. Vascular Reactions: Flushing, which causes small blood vessels to widen, is a common symptom of rosacea. These reactions are often triggered by factors like stress, heat, alcohol, spicy foods, or sun exposure.
  3. Chronic Inflammation: Rosacea is an inflammatory condition, and persistent inflammation can damage blood vessels, leading to facial redness and dilated capillaries.
  4. Environmental and Lifestyle Factors: Climate, pollution, certain cosmetic products, or inappropriate topical treatments can also worsen rosacea symptoms.
  5. Microbial Factors: Certain microorganisms, such as the Demodex folliculorum (a mite found on the skin), are more abundant in people with rosacea, which could play a role in its development.

Available Treatments for Rosacea

There is no definitive cure for rosacea, but several treatment options can help manage symptoms and improve skin appearance:

  • Topical Treatments: Creams and gels containing metronidazole, azelaic acid, or brimonidine can reduce redness and inflammation.
  • Antibiotics: Antibiotics like doxycycline are often used to treat more severe forms, such as papulopustular rosacea, due to their anti-inflammatory properties.
  • Laser and Pulsed Light Therapy: These treatments are effective in reducing persistent redness and dilated blood vessels.
  • Lifestyle Changes: Avoiding known triggers (heat, alcohol, spicy foods, etc.) can help prevent flare-ups and worsening symptoms.

 

What is the best beauty routine for rosacea?

A beauty routine tailored for rosacea aims to soothe the skin, reduce redness, protect fragile blood vessels, and prevent irritation. Here is a daily beauty routine designed for skin affected by rosacea:

1. Gentle Cleansing (Morning and Evening)

Choose a gentle cleanser that is soap-free and fragrance-free, respecting the skin's barrier. Opt for hydrating and soothing formulas, such as those containing thermal water, aloe vera, or lipid-replenishing agents (like glycerin). Avoid foaming cleansers or those containing alcohol, which can irritate and dry out the skin.

  • Product example: Gentle cleansing gel or soothing cleansing milk.

2. Soothing Toner (Morning and Evening)

Use an alcohol-free toner, enriched with soothing ingredients like rose water, chamomile, or niacinamide to reduce redness and calm the skin. Apply it gently with a cotton pad or pat it in with your hands.

  • Product example: Hydrating rose water toner or niacinamide toner.

3. Anti-Redness Serum (Morning)

Apply a serum specially formulated for rosacea-prone skin, containing anti-inflammatory and soothing active ingredients such as niacinamide, azelaic acid, or licorice extract. These ingredients help strengthen capillaries and reduce the appearance of redness.

  • Product example: Niacinamide or azelaic acid anti-redness serum.

4. Soothing Moisturizer (Morning and Evening)

Choose a moisturizer formulated for sensitive or rosacea-prone skin, rich in soothing ingredients like thermal water, ceramides, or bisabolol. Look for products that strengthen the skin's barrier, minimize inflammation, and provide intense hydration.

  • Product example: Soothing moisturizer with thermal water or ceramides.

5. Sun Protection (Morning)

Apply a broad-spectrum sunscreen (minimum SPF 30) every morning, even on cloudy days. UV rays worsen rosacea by damaging capillaries and triggering inflammation. Opt for mineral filters (zinc oxide or titanium dioxide) as they are less irritating for sensitive skin.

  • Product example: Mineral sunscreen with SPF 30 or higher.

6. Corrective Makeup (If desired)

Use a green color corrector to neutralize redness, followed by a tinted cream or foundation formulated for sensitive skin. Choose non-comedogenic, fragrance-free products enriched with soothing agents.

  • Product example: Green redness corrector and soothing foundation for sensitive skin.

7. Specific Treatments (Evening)

Incorporate specific treatments like serums or creams with azelaic acid or ceramides, which help repair the skin and reduce redness over time. Consult a dermatologist for recommendations tailored to your specific case.

8. Soothing Masks (1 to 2 times per week)

Apply a hydrating and soothing mask to comfort the skin and reduce redness. Look for ingredients such as honey, aloe vera, or colloidal oatmeal for their calming and anti-inflammatory properties.

  • Product example: Hydrating mask with aloe vera or colloidal oatmeal.

Additional tips for rosacea-prone skin:

  • Avoid triggers: Limit sun exposure, avoid alcohol, spicy foods, hot beverages, and stress as much as possible.
  • Prefer lukewarm water: Wash your face with lukewarm water rather than hot water, which can dilate blood vessels.
  • Choose soft textiles: Use towels and pillows made of soft fabric (like cotton or silk) to avoid irritation from friction.
  • Consult a dermatologist: If symptoms persist or worsen, consult a professional for appropriate medical treatment.
