In a bold move set to shake up the high street beauty market, Superdrug has officially launched its Mega Monday Deals, a new weekly sale event designed to rival the popular Boots £10 Tuesday.
Massive Savings on Premium Skincare
The inaugural event, which kicked off on Monday, 24th November 2025, features dramatic price cuts on high-end products. The standout offer is the GlowCocktail Marine Collagen Firm & Repair Serum, which has seen a staggering £80 reduction. Originally priced at £89.99, this potent skin-tightening serum is now available for just £10 for one day only.
This represents an incredible 88% discount on a product designed to reduce signs of ageing, tighten skin, and improve overall texture for a more youthful appearance.
How Mega Monday Stacks Up Against the Competition
While Boots sets a flat £10 price for all items in its Tuesday promotion, Superdrug's Mega Monday offers more variety. Although most items are slashed to the £10 mark, the discounts and final prices can vary each week, giving shoppers a different range of bargains to explore.
The GlowCocktail serum isn't the only premium product receiving a massive price cut. Superdrug has also reduced the ErthSkin Retinol Collagen Boost Eye Cream from £69 to £10, offering another exceptional deal for beauty enthusiasts.
For those considering the GlowCocktail serum elsewhere, Debenhams currently offers it for £13.01, making Superdrug's £10 price the clear market leader for this product.
Why This Serum is a Standout Buy
Formulated with a powerful blend of marine collagen, nourishing oils, and rejuvenating peptides, the GlowCocktail serum aims to improve skin elasticity, smooth fine lines, and refine skin texture. Its deep hydrating properties are particularly beneficial for combating the dry, dull skin often associated with the winter months.
Although the product has only one review on Superdrug's website, it is a five-star rating that states: “Week 3 of using it, I can see the difference on my face, tighter and better texture. You do need to add it to daily routine, with moisturiser, at first it seems brittle but after few minutes brings out the moisture.”
Meanwhile, Boots is countering with its own promotion, having reduced the price of the Origins Ginzing Glow-Boosting Serum from £44 to £30.80, a serum renowned for delivering instant radiance.
With Superdrug committing to running its Mega Monday Deals every week, the battle for the beauty pound on the UK high street has just intensified, offering consumers more opportunities to bag premium products at bargain prices.
