IF you're one of the lucky ones, you'll have waved goodbye to the days of zits and blemishes in your teenage years.
Or if you're really jammy, you'll have breezed through those with barely a blemish on your skin.
But for many women, acne in later life is becoming an increasing concern.
Earlier this year the rise of adult acne was likened to an 'epidemic' by one dermatologist.
In 2015 a study of 92 private dermatology clinics found a 200 per cent rise in the number of adults seeking specialist treatment for acne.
What's worse, women are five times more likely than men to be affected by adult acne, with a number of factors including fluctuating pregnancy hormones, the menstrual cycle and changing methods of contraception (the pill, coil or patches) triggering outbreaks.
Even celebrities have suffered - Cameron Diaz, Kate Moss and Victoria Beckham to name just a few.
But there are things we can do about it. Here are seven ways to tackle those stubborn spots.
Change your contraceptive pill
Consider changing your pill to Dianette, which is often prescribed to women with severe acne that has not cleared up with the use of antibiotics or other treatments.
It contains cyproterone acetate, which is an anti-androgen.
Androgens stimulate skin growth, including that of the sebaceous glands which produce an oily substance called sebum.
Sebum is essential to make the skin waterproof and lubricated, but if too much is produced it can cause the sebaceous glands to become blocked and infected, which leads to acne.
Be aware that doctors can be hesitant about handing this out as it is associated with a higher risk of blood clots and certain types of cancer.
Change your face wash routine
Certain face washes can dry out the skin, which means you end up over-compensating with the moisturiser and make it greasy.
If your skin is prone to acne, try using La Roche-Posay Purifying Cleansing Gel, a facial wash for oily skin.
Recommended by dermatologists, this foaming gel helps to eliminate impurities and excess sebum, leaving the skin feeling clean and fresh without drying it out.
You can buy it from Boots, where a 200ml tube costs £11.
