Refreshing your skincare routine isn’t always as easy as it sounds. Before you even think about which new products you want to try, there’s the cost involved in buying full-sized serums, moisturisers and treatments, especially when you’re not sure which’ll work for you.This is where mini skincare sets can be a useful option. They offer a way to test out new products and discover new favourites without committing to full-sized bottles, making them a handy choice for anyone looking to switch up their routine without spending too much.The Ordinary has become a favourite among beauty shoppers thanks to its straightforward approach to skincare. And for anyone who’s a fan of the brand (or a hopeful fan), there’s currently a limited edition gift set on sale at John Lewis. The miniature bundle brings together three of its popular skincare formulas for less, including the glycolic acid 7% exfoliating toner, niacinamide 10% + zinc 1% serum and hyaluronic acid 2% + B5 serum.The set combines three of The Ordinary’s popular formulas, covering some of the key steps in a skincare routine.

She wrote: “For its price, aesthetic packaging and FIVE types of hyaluronic acid, you probably can’t get a more effective form of HA alone. And The Ordinary’s product is much more than ‘just’ HA, too, featuring ceramides to combat flaking and dryness, pro-vitamin b5 to heal inflammation and fatty acids to prevent the development of fine lines.”When she tested the glycolic acid 7% exfoliating toner, Lucy found it to be a pedicure must have. This formula works by exfoliating the skin and helping to remove the build-up of dead skin cells After a few nights of testing, she was sold. She wrote: “All in all, the glycolic acid 7% toner couldn’t have exceeded my expectations more. I expected minimal results and a need to repeat the process several nights in a row, whereas in actuality I saw instant and dramatic results.”Beauty expert Louise Whitbread was similarly impressed by the niacinamide 10% + zinc 1% serum, describing it as an “affordable, high-strength formulation.” In her roundup of the best niacinamide products she also received advice from Dr Aiza Jamil, a consultant dermatologist who said “[It’s] a great, affordable option. Zinc is added to help regulate oil and calm inflammation, so this is a great option for those who have oilier skin.”This Boots beauty box includes a full skincare routine for £50
