Beauty may be only skin deep but the cost of looking your best might find you reaching deep into your pockets.

Spending on make-up, diet and exercise, fragrances, skin care, hair products and cosmetic surgery adds up to a staggering $160bn per year worldwide.

South Koreans have more plastic surgery than people in any other nation per capita. One in 77 people went under the knife in 2011, according to the International Society of Aesthetic Plastic Surgeons.

But looking beautiful doesn’t require an operation, a syringe of Botox or a bank loan. By following these simple steps, you can get great deals on make-up, salon appointments and even special cosmetic tools — in 90 seconds.
