Potential Rosacea Triggers in Cosmetics
Fragrance (Parfum) – Natural or Synthetic
• One of the most common irritants
• Can provoke stinging, burning, and redness
• Even essential oils (lavender, citrus, peppermint) can be reactive for some
Alcohol (Ethanol, SD Alcohol, Denatured Alcohol)
• Common in toners, astringents, and acne treatments
• Dries out the skin and disrupts the barrier, leading to more inflammation
Essential Oils
• While natural, they’re potent and often sensitising for rosacea-prone skin
• Examples: peppermint, eucalyptus, tea tree, citrus oils
Astringents
• Witch hazel, menthol, camphor, and mint derivatives
• Often included in “oil-control” or “pore-minimising” products
Exfoliants
• Physical exfoliants (scrubs, microbeads): can cause micro-tears in sensitive skin
• Chemical exfoliants: AHAs (glycolic, lactic), BHAs (salicylic acid), and retinoids can trigger inflammation
Preservatives
• Especially methylisothiazolinone (MI) and methylchloroisothiazolinone (MCI)
• Sodium levulinate and sodium anisate are generally better tolerated and natural.
Chemical Sunscreens
• Ingredients like oxybenzone, avobenzone, octocrylene, and octinoxate may cause stinging or irritation
• Mineral sunscreens (zinc oxide or titanium dioxide) are generally better tolerated
Silicones (Dimethicone, Cyclopentasiloxane)
• Can trap heat and worsen flushing in some sensitive individuals
Rosacea-Friendly Skincare:
• Speak to a facialist or corneotherapist that knows about rosacea
• Look for products labelled fragrance-free, or for sensitive skin
• Choose simple formulations with minimal ingredients
• Choose for barrier-repairing ingredients like: Ceramides, Niacinamide (in low concentrations), Zinc, Panthenol or Centella asiatica
• Always patch test new products before applying them to the full face
