Beauty fans race to Next to fill up bargain beauty boxes with products of their choice for just £15 -but there’s a catch

"No matter how much time and money you spend on your beauty routine, if you’re not getting the basics right, the rest is wasted.

"There aren’t many non-negotiables, but these are the biggest beauty mistakes sabotaging your regime."

• Not wearing SPF: Sun-damage is the main cause of premature skin ageing, so if you want to keep your skin looking plump and glowing, sun cream is vital. 
• Using expired products: Best case, they’re ineffective and don’t deliver the results they promise, worst case they cause irritation and infection. The shelf life of beauty products differ - for example, mascara is usually good for 3-6 months while lipstick can last for 9-18 months. Check the ‘POA’ symbol on the packaging (it looks like a jar and will have a number inside for how many months it’s safe once opened. If you can’t remember when you opened your product, throw it away and start again, marking the month and year with a permanent marker on the packaging. 
• Not knowing your undertones: If you’re using make-up with the wrong undertones, it’ll never look natural no matter how much you blend it! An easy trick to work out whether you have cool, warm or neutral undertones is to check the veins on your wrist - if they look blue, you have cool undertones, if they’re green, you have warm and if they’re a mix you have neutral. 
• Skipping heat protector: It might feel unnecessary, but much like sun damage on the skin, excess heat is the most common cause of hair damage. So, if you want shiny, healthy hair, or you’re trying to grow it longer, using a heat protection product is key. 
• Not washing your face before bed: it’s as simple as this, if you’re not washing your face before you go to sleep, everything that’s been on your skin during the day is sitting there for even longer, clogging your pores and drying out the surface. Any skincare applied on top isn’t going to be effective with a layer of dirt underneath, and you’re probably going to end up with dirty pillows too - yuck!
