The €7 skincare serum that sold 100,000 bottles after video showed its miraculous effects

According to eager fans, it's a 'game-changer.'

The Ordinary is a budget skincare brand that has amassed quite the cult following over the past few years. Known for their sleek packaging and simplified approach to demystifying ingredients, The Ordinary has recently found themselves struggling to meet demand, after a TikTok user recently went viral with a video about the brand's Peeling Solution serum. In fact, so impressed were viewers with what they saw, that the Peeling Solution was bought by a whopping 100,000 users after they watched a video on its miraculous effects. Here is the product description on the popular serum: "Alpha hydroxyl acids (AHA) exfoliate the skin's topmost surface for a brighter and more even appearance. Beta hydroxyl acids (BHA) also exfoliate the skin with an extended function to help clear pore congestion. This combined 32% AHA/BHA solution offers deeper exfoliation to help fight visible blemishes and for improved skin radiance. The formula also improves the appearance of skin texture and reduces the look of fine lines with continued use. This formula contains a studied Tasmanian Pepperberry derivative to help reduce irritation associated with acid use. This derivative is of plant origin and varies in colour seasonally and this colour variation may be apparent in the formula from time to time. This formula is further supported with a crosspolymer form of hyaluronic acid for comfort, Vitamin B5 to assist healing and black carrot as an antioxidant." Retailing for just €7.20 in Boots, the serum is currently out of stock, but will no doubt be re-stocked soon if you are eager to try it out for yourself. What we love most about the products from The Ordinary, apart from the fact that they genuinely work, of course, is that all the brand's products are free from nasties, including alcohol, oil and silicone, and is also gluten-free, vegan and completely cruelty-free.
