Sensitive Skin and Rosacea: How to Care for Reactive Skin

Sensitive skin is one of the most common traits I see in my patients — and also one of the most misunderstood. Many people tell me "my skin is very sensitive" to describe very different situations: from skin that gets irritated in cold weather to diagnosable rosacea that requires medical treatment. Understanding what kind of sensitivity you have is the first step to caring for it properly.

What is sensitive skin?

"Sensitive" skin is an umbrella term for skin that easily reacts to stimuli that don't affect most people: temperature changes, wind, certain cosmetic ingredients, stress or foods. Symptoms include redness, burning, itching, dryness and flaking.

The cause can be:

• A weakened skin barrier: the barrier's main job is to protect the skin from external irritants and retain water. When it is compromised, the skin becomes dehydrated and reactive
• A tendency to vascular redness: people with very fair skin and blood vessels close to the surface can flush easily
• Specific skin conditions: atopic dermatitis, rosacea and psoriasis, among others

What is rosacea?

Rosacea is a chronic inflammatory skin disease, whose cause is not fully understood, that mainly affects the center of the face: nose, cheeks, forehead and chin. It is estimated to affect 10% of the adult population.

Its main features are:

• Persistent redness (erythema) in the center of the face
• Flushing episodes: intense, temporary blushing that can be triggered by heat, alcohol, spicy food, emotions or exercise
• Telangiectasias: small, dilated blood vessels visible on the skin (spider veins)
• Papules and pustules: acne-like lesions (which is why it's sometimes called "acne rosacea," although they are different conditions)
• In advanced forms: rhinophyma (thickening of the nose, more common in men)

Rosacea can't be cured, but it can be controlled very well with treatment and the right routine.

Rosacea triggers

Identifying your own triggers is key to managing it:

• Extreme temperatures: intense heat, hot water, saunas
• Food and drink: spicy food, alcohol (especially red wine), caffeine
• Sun exposure: the sun is one of the most common triggers
• Emotional stress
• Intense exercise
• Sudden temperature changes
• Some cosmetics: containing alcohol, fragrance, menthol, witch hazel or strong acids

Not every patient reacts to the same factors. Keeping a flare diary can be very helpful.

Medical treatments for rosacea

Treatment depends on the subtype of rosacea and its severity:

Rosacea with redness and telangiectasias

• Vascular laser / intense pulsed light (IPL): reduces telangiectasias and background redness. These are the most effective treatments for this component
• Topical brimonidine: topical vasoconstriction that temporarily reduces redness

Papulopustular rosacea (acne-like)

• Topical metronidazole or azelaic acid: first-line for papules and pustules
• Topical ivermectin: very effective and well tolerated
• Oral antibiotics (sub-antimicrobial-dose doxycycline): for moderate-to-severe flares

Rhinophyma

• Ablative CO2 laser or surgery: for advanced cases with significant thickening

A routine for sensitive skin and rosacea

Cleanse without irritating

• Lukewarm (not hot) water
• A gentle cleanser without fragrance, alcohol or harsh surfactants (no SLS)
• Apply with your hands, never with sponges or brushes
• Don't rub when drying — pat gently

Hydration that repairs the barrier

The most useful ingredients for sensitive skin:

• Ceramides: natural components of the skin barrier
• Niacinamide at 2–4%: anti-inflammatory and barrier-strengthening (at low concentrations — high ones can irritate rosacea)
• Panthenol (provitamin B5): soothing and repairing
• Colloidal oatmeal

Avoid: fragrance, denatured alcohol, irritating essential oils (lavender, peppermint, citrus) and high-concentration acids.

Sunscreen: essential

The sun is the most common rosacea trigger. SPF is indispensable, but you need to choose one that's well tolerated. My recommendations:

• Mineral filters (titanium dioxide, zinc oxide): generally better tolerated than chemical filters in rosacea
• Lightweight, fragrance-free textures
• Tinted if your skin is very reactive (iron oxide tints add protection against visible light, which can also trigger rosacea)

Ingredients to avoid with rosacea

• Strong acids in high concentrations (topical retinoids, high-dose AHAs/BHAs)
• Alcohol in formulas
• Fragrance and essential oils
• Menthol, camphor, witch hazel
• Very hot water

Retinoids can be used in mild-to-moderate rosacea, but starting at the lowest concentrations and increasing very gradually.

When should you see a dermatologist?

If you have persistent redness in the center of your face, frequent episodes of intense flushing, visible spider veins, or bumps that don't respond to usual acne treatments, a dermatological evaluation is important. Rosacea tends to progress without treatment.

Do you have reactive skin and don't know exactly what triggers it? During the consultation we evaluate your skin type, identify the correct diagnosis and design a tailored treatment plan and routine. Book your appointment with Dr. Alejandra Téllez in Bogotá.
