The retailer, which runs more than 850 stores across the UK and Ireland, said like-for-like sales lifted 6.8% in the five weeks to 2 January compared to a year ago, boosted by cosmetic sales.
It said the mild weather over the period saw sales of bronzing products jump 20% compared to 12 months ago, "as party-goers eschewed tights for bare legs."
The retailer, which is the second biggest health and beauty chain behind Boots, said that lipsticks were among its top performers, with brands such as Maybelline, Gosh and Makeup Revolution and red berry shades among the most popular.
It added that fragrances also grew by 12% over the period year-on-year, with brands by Stella McCartney, Dolce & Gabbana and Daisy by Marc Jacobs leading the pack.
The business said as a promotional tool, it gave away free teddy bears to all customers who spent £30 or more on fragrances.
It added its Health & Beautycard loyalty programme grew from around five million customers to more than seven million during the year.
The chain said over the last quarter of its year it opened four new stores, with the most recent being at Edinburgh Airport, the first airside pharmacy for Superdrug.
The business added it plans to open 20 new stores in 2016.
Superdrug managing director, Peter Macnab, said: "This Christmas we concentrated on offering customers as many reasons as possible to shop at Superdrug - from market-leading prices to a wealth of free gifts."
The chain is owned by international health and beauty group AS Watson, which runs more than 12,000 stores in 24 markets.
In turn AS Watson is part of the ports-to-energy conglomerate CK Hutchison Holdings, run by Hong Kong billionaire Li Ka-shing.
