GEMMA: SUDOCREM, £2.99

Gemma Garrett (36) is a make-up artist, model and former Miss GB. She says: One thing which a lot of people in the beauty industry frown upon — but has worked for me since the age of 17 — is Sudocrem, which costs about £2. If I ever have a spot or a shaving rash or any kind of skin irritation, I swear by it. People are horrified because it does have a lot of chemicals in it, and these days everyone talks about using natural products. But Sudocrem is so effective. If you only put it on targeted areas it really does what it’s supposed to. I also remember reading an interview with Cheryl Fernandez-Versini and she used it in exactly the same way. I think our mums probably told us to use it for our spots straight away. You will always find a couple of pots of it in my beauty box.”
