Practical guides to natural skincare, aromatherapy and supplements: how to use them safely, what the label means and when to ask a pharmacist.

Essential oils are strong, so the rules are simple: dilute them before they touch skin, never swallow them, keep them away from cats and children, and store them cool and dark.

A carrier oil dilutes essential oils so they are safe on skin. Light oils suit the face and quick massage, richer ones suit dry skin, and the most stable oils last longest.

A natural deodorant tackles smell, not sweat. Pick a scent, apply a small amount to clean, dry skin, and switch to a gentler formula if bicarbonate of soda irritates.

A healthy looking beard needs a short daily routine: wash it gently, apply a little oil while it is damp, comb it through, and look after the skin underneath.

Supplements are sold as food in the UK, not medicine. The label tells you the dose, the %NRV and the daily limit; a pharmacist can tell you whether you need it at all.

A plant protein powder is a convenient way to add protein, not a necessity. Compare protein per serving, allergens and price per serving, and add up any vitamins it contains.
