The problem: Stress dilates our blood vessels, which causes redness and can aggravate Rosacea. Cold weather has the same irritating effect.

The solution: Steer clear of harsh ingredients and formula, and look for kind-to-skin ingredients to soothe flushing. Formula Advanced Skin Solutions Pro-Tolerance Anti-Redness Soothing Cleansing Lotion, £9.50, M&S, is a gentle cleanser that reduces sensitivity and redness. For an instant fix, look for a yellow-tinted concealer, which neutralises redness.
