The Body Shop has seen earnings rise despite criticism of its decision to be bought by cosmetics giant L'Oreal.
The Body Shop's image problems have not dented its appeal
Like-for-like sales in the eight weeks to 22 April were up 5%, better than its last full-year results, the firm said.
The company, which was started by Dame Anita Roddick, added that pre-tax profit in the year ending 25 February also rose by 5% to £37.6m.
There had been fears that consumers might have felt the firm's ethical image had been harmed by the takeover.
The Body Shop has built its business around an image of ethically-sourced products that were not tested on animals.
While L'Oreal has not been involved in animal testing since 1989, it does use products that have been tested on animals.
The Body Shop was also criticised because L'Oreal is 26.4%-owned by Nestle, which is under fire for its marketing of powdered baby milk in developing countries.
When she announced the deal, Dame Anita denied that that the Body Shop was joining with "the enemy".
The Body Shop operates 2,000 shops in 54 countries from its base in Littlehampton, West Sussex.
