Glamour UK has published a guide to seven early Prime Day mascara deals available now on Amazon ahead of Prime Big Deal Days 2026, scheduled for 6-7 October in the UK. Featured discounts include Lancôme Lash Idôle Waterproof, L’Oréal Telescopic and Clinique Lash Power, with some brands up to 50% off.
Glamour UK has published a shopping guide highlighting seven early Prime Day mascara deals already available on Amazon, weeks before the retailer’s Prime Big Deal Days 2026 event on 6-7 October. The list includes discounted picks from Lancôme, L’Oréal Paris, Clinique and KIKO Milano, with the outlet reporting that some mascaras that rarely go on sale are currently discounted by up to 50%.
According to the Glamour UK report, the featured deals include the Lancôme Lash Idôle Waterproof Mascara, the L’Oréal Paris Telescopic Extensionist Lengthening & Curling Mascara, the Clinique Lash Power Mascara and the KIKO Milano Maxi Mod Volume & Definition Mascara. The guide also points readers to Amazon discount codes that can be applied at checkout for additional savings. Glamour UK reports that many of the best-rated options in its roundup are priced under £10 during the early sale period.
The outlet states that each mascara in the guide was selected against set criteria: a "cult reputation backed by thousands of five-star reviews", a Prime Day saving that justifies buying immediately, and a formula and wand that delivers on length, lift, volume or curl. The author, a shopping writer who says she has covered beauty for Glamour, ELLE and Cosmopolitan for more than five years, writes that she has personally tested the products included.
The deals are live before the main event. Amazon Prime Big Deal Days 2026 runs in the UK on 6-7 October, spanning two days of discounts across beauty, fashion, tech and home categories. Prime Day deals are exclusive to Amazon Prime members.
Why Early Mascara Deals Matter Now
Beauty products from premium brands such as Lancôme and Clinique are rarely discounted, according to the report, which notes that L’Oréal’s Telescopic line in particular seldom goes on sale. The current discounts of up to 50% therefore represent an unusual opportunity for shoppers who use these products regularly.
The early deals also matter because Prime Day pricing is time-limited and stock-dependent. Glamour UK advises shoppers to build wishlists now and check back during the main event on 6-7 October, when the outlet plans to publish further deal roundups as they appear. For budget-conscious shoppers, the report indicates several well-reviewed options are currently available for under £10.
How Prime Day Beauty Discounts Evolved
Amazon Prime Day launched in 2015 to mark the company’s 20th birthday, beginning as a 24-hour sale focused on technology products. It has since expanded into a multi-day event reserved for Prime members, covering categories from electronics to beauty. In the UK, the autumn edition is branded Prime Big Deal Days, scheduled for 6-7 October in 2026.
Although the event is best known for big-ticket gadgets, the Glamour UK report notes that beauty discounts have become a meaningful part of the sale, with premium mascaras now among the discounted items. The current early offers precede the official event, a pattern Amazon has followed in previous years by releasing deals in the lead-up to the main sale days.
“Mascaras that rarely ever go on sale (we see you, L’Oréal Telescopic) are now up to 50% off, and many of the best-rated options are under a tenner.”

Deal Prices and Availability Not Guaranteed
Amazon has not publicly confirmed which mascara discounts will run during the main 6-7 October event, and current early-deal prices may change or expire before Prime Big Deal Days begins. Stock levels and discount depths during the event itself remain unknown.
The claim that every mascara listed has a cult reputation backed by thousands of five-star reviews comes from the Glamour UK author’s own testing and editorial criteria, not from independent verification. Exact percentage discounts for each of the seven featured products were not itemised in the source material, so shoppers should check live Amazon listings for current pricing. Additional discount codes referenced in the report are subject to Amazon’s terms and expiry dates.
Watching for the 6-7 October Sale
The main event, Prime Big Deal Days 2026, takes place in the UK on 6-7 October. Glamour UK says it will publish updated mascara deal roundups as new offers appear during the event. Shoppers who want to take advantage of the deals will need an active Amazon Prime membership.
In the meantime, the early offers listed in the guide remain available, though for how long is not specified. Readers planning purchases can compare live prices against the report’s picks, apply any valid checkout discount codes, and monitor price changes in the run-up to October.
