With the Amazon Prime Day finish line now firmly in sight, I'm taking one last sweep through the beauty deals before prices start bouncing back to normal – and Elemis is still delivering one of best (and most luxurious) skincare discounts I've spotted all week. Given how popular the brand's bestselling cleansing balm is with celebrities, beauty editors and skincare enthusiasts alike, it's a deal that's survived longer than I expected.If you've spent the past few days layering on SPF to survive the heatwave, you'll know the importance of a cleanser that can properly shift your sunscreen, make-up and the day's grime without leaving your face feeling tight afterwards.Right now, the limited-edition black cherry version has dropped from £52 to £32 (Amazon.co.uk), saving you £20. The original formula is also reduced to £33.80 (was £52, Amazon.co.uk), while the fragrance-free pro-collagen naked cleansing balm – a top pick if you suffer with sensitive skin – has fallen to £36.40 (was £52, Amazon.co.uk).Known for its signature balm-to-oil-to-milk texture, the cleanser combines ingredients such as padina pavonica, starflower oil, and rose and mimosa wax to leave skin feeling clean, soft and comfortable. With Prime Day entering its final day very soon, this is one beauty deal I'd be reluctant to leave sitting in my basket for much longer.Read more: Best Dyson airwrap deals for Amazon Prime DayElemis pro-collagen cleansing balm, black cherry: Was £52, now £32, Amazon.co.uk(Elemis)Elemis’s bestselling cleansing balm instantly upgrades any skincare routine, with its luxurious formula and impressive results. Thanks to Amazon Prime Day, it is reduced by £20 right now, taking its price from £52 to £32.11 in the black cherry. Meanwhile, the unscented (Amazon.co.uk) is reduced by 30 per cent, the original (Amazon.co.uk) by 35 per cent and the rose version by 19 per cent (Amazon.co.uk). This mega saving feels a beauty steal well worth making the most of this Prime Day – whether you’re stocking up or have always wanted to try it.The formula itself is a big part of why beauty editors, facialists and skincare devotees keep returning to it. What begins as a buttery balm quickly melts into a silky oil, dissolving everything from stubborn SPF to waterproof mascara without the tugging, rubbing and cotton-pad gymnastics often required of your typical micellar water. And while the original version is currently still full price, I rate the variations on offer for Prime Day just as much. When I reviewed the black cherry pro-collagen cleanser last year, I found it "removes 90 per cent of make-up in one cleanse" and loved that it "doesn't sting eyes," making it particularly effective around lashes and sensitive areas.At the heart of every version of the balm is padina pavonica, an antioxidant-rich brown algae prized for its hydrating and skin-softening properties. Combined with nourishing oils and waxes, it leaves skin feeling comfortably cleansed rather than tight or stripped.The results have impressed the wider IndyBest team, too. In our guide to the best cleansers, reviewer Ella Duggan found the balm could "aid skin's elasticity and create a visibly smoother complexion", adding that after use her "skin felt smooth and was left with a velvety texture".Whether you're replacing an empty tub or finally seeing what makes this cleanser such a perennial best-seller, a saving of more than £20 in a few scented and unscented options makes this Prime Day a great opportunity to stock up.
