Understanding The User
PRIMARY RESEARCH
01
I conducted a user survey with 30 participants ranging from their 20s to 50s, all of whom had experience shopping at Tonic15. The survey comprised 20 questions, covering aspects such as shopping experience and feedback. The objective was to gather quantitative data to gain insights into user behaviour while navigating the Tonic15 website.

PROCESS
The purchasing process received approximately 50% negative feedback, contributing to an unsatisfactory buying experience. This dissatisfaction was attributed to issues such as the presence, absence, or location of the CTA(e.g. add to cart) button, as well as some features that were not easily noticeable.

Consumer research supports our predictions from Reportlinker.com on the popularity of South Korean beauty products. Conducted by Statista in 2019, the research revealed that approximately 52.4% of respondents in the UK stated that K-beauty is popular.
In another survey by Statista in 2021 in the UK, around 28% of respondents stated that the wide variety of product types was a main positive aspect of consumers' impression of Korean beauty products.
Reportlinker.com reported that the global K-beauty products market is expected to grow at a CAGR of 10.07% over the forecasted period of 2022 to 2030. The market growth is facilitated by key drivers such as the rising need for organic products, the surge in e-commerce as well as social media and the curiosity to try new and innovative products.

KEY INSIGHTS
03
The research highlights the substantial popularity of K-beauty in the UK, driven by users' fascination with diverse and innovative products. To capitalize on this trend, websites should prioritize a user-friendly experience, granting easy access to information about products. Streamlining the purchasing process is also crucial to deliver a simple and efficient user experience.

PAIN POINTS

Difficulty finding products due to a hidden search bar and an inconspicuous search icon.
3 HIDDEN IDENTITY
Users feel disconnected from TONIC15's unique character on the skincare website due to obscured branding elements.

Style Guide
I maintained the same color palette and font style as the original design asset that was recently updated. However, upon discovering that users were unable to locate any TONIC15 identity on the website, I redesigned it to effectively showcase the brand's identity and character, ensuring a strong brand representation.
