I've always had good skin, but in the past couple of months it's become blotchy. My pores have opened and my cheeks are often red and puffy.

Try to detect a reason for the change: different make-up or creams, a change in diet, higher intake of caffeine or fast food, or a particularly stressful time. You could have a build-up of toxins in your system. Cleanse and detox with a diet of organic fruit and vegetables, whole grains, seeds and nuts. Eat lots of fibre, which binds with toxins and removes them, drink lots of water, and take herbs such as milk thistle and green foods such as seaweed and wheat grass. The best detox aids on the high street, as reviewed by Proof magazine, are Biofirm by New Nordic (from the NutriCentre, 020-7436 5122) and Seagreens Amalgam Detox Capsules (from Oceans of Goodness, 01444 400403).

My six-year-old daughter has had a tiny granuloma in her navel since birth. It still bleeds sometimes, particularly if she is run down.

A granuloma in this area could be subject to low-grade infections and the anti-infective (especially anti-fungal) properties of echinacea would be of great benefit. A Vogel Echinacea cream, from Bioforce (£4.49 for 35g, 01294 277344, bioforce.co.uk, or from good healthfood stores) contains extracts of certified organically grown wild pansy and echinacea flowers and roots. Apply topically twice a day. To boost your daughter's immunity, particularly when she is run down, try Sambucol For Kids (from healthfood shops) - this was developed by a world-renowned virologist, and contains black elderberry extract, propolis and vitamin C.
