The skincare industry is worth roughly £2.6 billion. TWO POINT SIX BILLION. That’s an almost incomprehensible amount of money and it goes some way towards explaining why there are so many skincare brands, products, and ingredients. It’s overwhelming. Whereas makeup typically (but not always) comes in a little cheaper than skincare and is based more on colour theory, which makes it easier to mix and match palettes, foundations, and concealers, skincare is a more precise beast. You can’t just swap moisturisers in and out in the same way as makeup because you need to give them time to settle into your skin. Mixing up your skincare routine too frequently can cause flare-ups, skin purging, and more, not to mention the fact you could be throwing money down the drain.
