Who needs expensive unguents to combat dry skin when there's a cost-effective solution at your local health food store? Vitamin E oil is often overlooked in favour of specialist creams, but it's great for healing scar tissue and dry skin. We even use it on patches of eczema, which then clear up in days. Apply where skin's really dry before going to bed and also add to elbows and knees to combat scaliness. Our bottle costs around a tenner from Holland & Barrett and because you need only the tiniest amount, it lasts for years.
