Rosacea: a complete treatment guide.

What is rosacea?

Rosacea is a chronic inflammatory skin condition that primarily affects the central face — cheeks, nose, chin, and forehead. It involves persistent redness, episodes of flushing, visible blood vessels, and sometimes acne-like bumps. Unlike most skin conditions, rosacea also has a vascular component (the blood vessels under the skin become more reactive) and often an ocular component (eye dryness and irritation).

Rosacea typically begins between ages 30 and 50, is more common in fair-skinned people of Northern European descent, and affects women more often than men — though men typically experience more severe cases.

The four subtypes of rosacea

Most people have features of more than one subtype, especially erythematotelangiectatic + papulopustular.

Symptoms

• Persistent redness (erythema) on cheeks, nose, chin, forehead
• Flushing episodes that come and go
• Visible blood vessels (telangiectasia) on cheeks and nose
• Acne-like bumps and pustules (without blackheads)
• Burning, stinging, or sensitivity
• Dry, rough, or peeling skin patches
• Eye irritation: dryness, redness, foreign-body sensation
• Skin thickening (in advanced cases, especially the nose)

Causes and triggers

The pathogenesis of rosacea is multifactorial:

• Vascular dysregulation — facial blood vessels overreact to triggers
• Neurogenic inflammation — the nervous system contributes to flushing
• Immune system dysfunction — abnormal cathelicidin activity
• Demodex mite overgrowth — these mites are normal on skin but excessive in rosacea
• Genetics — strong familial pattern, especially in fair-skinned populations

Common rosacea triggers

• Heat — hot showers, hot weather, hot drinks
• Alcohol — especially red wine
• Spicy foods
• Sun exposure (the #1 trigger)
• Stress
• Cold or windy weather
• Vigorous exercise
• Harsh skincare — exfoliants, fragrance, alcohol, retinoids
• Certain medications — niacin, vasodilators, topical steroids

How rosacea is diagnosed

There is no single test for rosacea. Diagnosis is clinical, based on a dermatologist's examination and your trigger history. The 2017 ROSCO consensus uses a phenotype approach: identify which specific symptoms you have (redness, papulopustules, telangiectasia, ocular features) and treat each.

If you have not been formally diagnosed, see a dermatologist before starting treatment. Rosacea is commonly mistaken for acne, lupus, perioral dermatitis, seborrheic dermatitis, and contact dermatitis.

Prescription treatments

Topical

• Azelaic acid 15% gel (Finacea) — first-line for papulopustular rosacea. Anti-inflammatory and brightening.
• Ivermectin 1% cream (Soolantra) — targets Demodex mites. Effective in 12 weeks.
• Metronidazole 0.75% or 1% (MetroGel) — anti-inflammatory.
• Brimonidine 0.33% gel (Mirvaso) — vasoconstrictor for acute redness; effects last 12 hours.
• Oxymetazoline 1% cream (Rhofade) — alternative vasoconstrictor.
• Sulfacetamide-sulfur 10%/5% — anti-inflammatory wash for papulopustular rosacea.

Oral

• Doxycycline 40mg modified-release (Oracea) — sub-antibiotic, anti-inflammatory dose. First-line oral.
• Doxycycline 100mg — for severe inflammatory rosacea.
• Isotretinoin (low-dose) — for severe or phymatous rosacea unresponsive to other treatments.

OTC and skincare ingredients that help

• Niacinamide (4–10%) — anti-inflammatory, strengthens barrier, reduces redness
• Centella asiatica (Cica) — calms inflammation
• Azelaic acid (10% OTC) — gentler version of the prescription strength
• Sulfur — antimicrobial for papulopustular type
• Green tea extract — antioxidant, anti-inflammatory
• Licorice root extract — reduces redness
• Mineral SPF (zinc oxide, titanium dioxide) — UV protection without chemical filter irritation
• Ceramides + cholesterol — barrier repair
• Aloe vera — soothing, hydrating

Ingredients to avoid with rosacea

• Denatured alcohol, alcohol denat.
• Fragrance and essential oils
• Menthol, peppermint, eucalyptus, camphor
• Witch hazel
• Glycolic acid (use with caution; lower percentages and short contact time only)
• L-ascorbic acid vitamin C (try magnesium ascorbyl phosphate or sodium ascorbyl phosphate instead)
• High-strength retinoids (start very slow if any)
• Benzoyl peroxide (often worsens rosacea)
• Physical scrubs

A rosacea-safe routine

Morning

1. Lukewarm water rinse (or gentle non-foaming cleanser)
2. Niacinamide serum
3. Barrier moisturizer with ceramides
4. Mineral SPF 30+ (zinc oxide or titanium dioxide)

Evening

1. Gentle non-foaming cleanser (CeraVe Hydrating, La Roche-Posay Toleriane)
2. Prescription topical (azelaic acid, ivermectin, or metronidazole)
3. Wait 20 minutes
4. Barrier moisturizer with ceramides + cholesterol

This is the baseline. Add or modify only with dermatologist guidance.

Trigger management

The single most effective non-prescription rosacea intervention is identifying and avoiding your personal triggers. Pimpl can help with this — track flares alongside food, weather, stress, and sleep to identify patterns over weeks.

• Wear mineral SPF every single day, year-round
• Keep a trigger journal for at least 4 weeks
• Cool down quickly when overheated (cold water on wrists, ice cube on neck)
• Limit alcohol — especially red wine
• Sip cold drinks, not hot
• Choose mild exercise on flare days
• Manage stress (walks, breath work, sleep hygiene)

Laser and light treatments

For visible blood vessels and persistent redness that does not respond to topicals, laser/light treatments are highly effective:

• Pulsed dye laser (PDL) — gold standard for telangiectasia. Usually 3–5 sessions.
• Intense Pulsed Light (IPL) — broad-spectrum light targeting redness.
• KTP laser — for individual visible blood vessels.
• Nd:YAG laser — for deeper vessels.
• Ablative laser (CO2, erbium) — for advanced phymatous rosacea (skin thickening).

Each session is typically $300 to $600. Insurance rarely covers laser for rosacea.

Lifestyle and diet

• Identify food triggers via elimination diet (common: alcohol, spicy food, hot drinks, dairy, certain cheeses)
• Anti-inflammatory diet (Mediterranean-style)
• Manage stress — chronic stress directly worsens rosacea
• Get 7–9 hours of sleep
• Stay hydrated
• Mind gut health — the gut-skin axis is increasingly studied in rosacea
