The Challenge
Justmylook was facing several challenges common to the beauty industry. Beauty is a highly competitive sector, and customer acquisition, conversion, and retention are key obstacles for all beauty retailers.
Justmylook has a huge focus on customer acquisition. It invests heavily in PPC to drive traffic. This extends to other media as well. A recent OOH tube campaign in the capital also proved effective for customer acquisition, increasing its London customer share from 10-30%. However, Justmylook wanted a tool that would help ensure it maximises the conversion opportunities of its aggressive customer acquisition strategy. It also wanted to boost retention of existing customers, with returning shoppers currently comprising more than half its customer base (50-60%).
In addition, beauty customers are often offer-driven and tend to wait for sales, which means it’s important to give shoppers the confidence to buy at other times of the trading year too.
The Solution
Justmylook had considered a bolt-on social proof solution from another supplier. However, Taggstar’s work for a wide portfolio of leading retailers impressed Justmylook, and the retailer chose to adopt Taggstar’s dedicated social proof messaging offer instead.
Justmylook launched its proof of concept with Taggstar on 29th August 2025. The test saw Taggstar’s social proof messaging introduced on Justmylook’s website across the UK and Ireland. Running for 19 days, the full funnel test included 13 messages, such as ‘All Eyes on This! X others are looking at this right now, ‘Snapped-up! Sold 100+ times recently’, and ‘New Fave! Sold 100+ times recently’.
“As well as delivering impressive conversion and sales uplifts, the powerful ROI of 1299% proved that social proof messaging is a powerful yet cost-effective tool for boosting conversion and driving sales.”

The Results
The 19-day test resulted in a 1.78% conversion rate uplift, delivering 608 additional orders and £30,780 in incremental revenue. Average order values also rose, up 0.61%.
The return on investment was the most impressive metric, however. The ROI from the trial, measured by the cost of evaluation, deducted from the revenue delivered, and divided by the cost to deliver, equalled 1299.40%.
The Future
Justmylook is now considering additional social proof messaging from Taggstar to further focus customer attention on bestselling products. These will include Category Bestseller and Brand Bestseller, a new advanced messaging type within Taggstar’s messaging offer that highlights bestselling products by brand in real time.
Justmylook is also considering introducing seasonal icons. These help to further bring social proof messaging to life by theming messages around key selling periods, such as Christmas and Easter, to drive additional sales.
Luke Williams, founder and managing director of Justmylook, says: “In such a competitive industry, we need to do all we can to win, convert and retain customers. Social proof messaging has proved a powerful tool to achieve that, delivering impressive results quickly after a straightforward implementation supported by the in-depth, expert knowledge of the Taggstar team.”
“As well as delivering impressive conversion and sales uplifts, the powerful ROI of 1299% proved that social proof messaging is a powerful yet cost-effective tool for boosting conversion and driving sales. Our implementation wasn’t just about results, however. We also wanted to ensure we used social proof responsibly so that our customers didn’t feel pressured, which Taggstar provided invaluable advice on.”
The Future
Marjorie Leonidas, CEO at Taggstar, says: “We love to help our customers quickly see impressive results from their implementations of social proof messaging. Justmylook’s experience shows the incredible ROI that can be delivered and why social proof messaging should be a marketing tool used by all retailers.”
