At-home teeth whitening continues to grow in popularity, and this Black Friday, shoppers are taking advantage of major discounts across the sector. MySweetSmile is among the brands offering significant savings, with up to 40% off sitewide and daily free gifts until Cyber Monday.
One of the brand’s best-selling products, the teeth whitening powder, is now £17.99, down from £29.99. The peroxide-free, dentist-approved formula targets stains caused by tea, coffee, smoking, and ageing.
Users simply dip a damp toothbrush into the powder, brush for two minutes, and rinse. When used twice weekly, a tub lasts around six months, equating to 48p per use—further reduced to approximately 29p per session with the Black Friday discount.
MySweetSmile’s whitening strips are also discounted to £17.99 from £29.99. Using PAP (phthalimidoperoxycaproic acid) instead of peroxide, the strips gently break down stains without damaging enamel. Each pack contains 21 treatments, with visible results often reported after just one use.
The brand also offers a precision whitening pen, ideal for targeting specific areas. Now £14.99, down from £24.99, it takes just 10 minutes per application using its fine brush tip.
Shoppers can benefit from additional promotions, including “Buy 2 Get 1 Free” and “Buy 1 Get 1 50% Off,” plus free next-day delivery on orders over £30. Daily free gifts rotate throughout the sale, including hyaluronic gum serum, breath spray, whitening powder, and strips.
Other retailers are offering deals, too. Boots has selected HiSmile products at half price when buying two, including a V34 colour corrector serum for £19. Superdrug offers Smile Science Harley Street whitening strips at 25% off (£14.99), promising up to six shades of improvement in a 14-day, 20-minute-per-session treatment.
MySweetSmile has earned a 4.4 out of 5 rating on Trustpilot from over 7,200 reviewers and is trusted by more than one million customers worldwide.
Users praise the powder for effectively lifting stains, leaving teeth smooth and polished. Some note minor limitations, such as aftertaste or the need for consistent use, but overall satisfaction remains high.
The MySweetSmile Black Friday sale runs until 11:59 PM on December 1, 2025, offering shoppers a chance to stock up on popular teeth whitening products at discounted prices.
