My nose turn red easily

Very fashionable now.

Ha, Callistemon, too true!

Maryss, you may try a green-tinted concealer or primer. Quite a few makeup companies will have one. Clinique has a powder compact that looks yellow, but will help to cover redness. Stila has a 'one step corrector', Yves Saint Laurent has a 'Nu Tone Corrector'.
So whatever your budget, you can find something to cover redness in winter. Go to a make up counter and ask for assistance to find one that suits you.

My cousin has always had this and uses green concealer from chemist , perfect . Covers and blends . Has made her more confident, when going out of the house

I have developed this recently and presumed it's rosacea. I'm testing whether it's strawberries or tomatoes which cause the flareup. Think it's strawberries, although I find them difficult to give up.

I have a cream - Grahams natural skin, which definitely calms it down overnight and a cover up - Cicapair by Dr Jart from J Lewis.

Hope you find something which helps.
