SKINCARE

From fresh-faced beginner to skincare sage—your skin's evolution, made easy.

INTRODUCTION

Skingenious is a skincare app that delivers personalized routines and product recommendations tailored to each user's skin type, goals, and budget. Users track their skin's progress with daily check-ins, ensuring they receive the most relevant and up-to-date suggestions. My design challenge was to create a seamless, user-friendly all-in-one experience that not only educates but also provides detailed product reviews to guide confident purchase decisions.

To achieve this, I followed a five-phase design process—Empathize, Define, Ideate, Prototype, and Test—using a variety of user research methods to keep the design human-centered. As the sole UX/UI designer, I handled everything from market and user research to interface design and evaluation through each iteration, ensuring the app met both user needs and business goals.

background.

Having good skin is a positive sign showing that a woman is healthy and that it makes her feel confident with higher self-esteem. With the effects of covid, women are given more time for themselves and taking care of their skin is a way to help them keep up with their daily routine. Searching for an online skincare source that contains credible information and effective skincare products is not easy because of online difficult-to-realize paid articles and product promotion.

After obtain insights about my users and the design problem through researches, I created the User Persona, Empathy Map, and Job to be Done. All of which are great tools for my design workflows, helps me think more actively about my users and the decision making process.

The Power of Taking Control

“I feel more confident. 
I’m taking control of something that might be out of my control.”

“The Power of Taking Control” is one common pattern with my user interviewees. It’s the modern women wanting to take control of how they look, the products they choose, how they want other people to look at them, and how they make other decisions in life. 

THE
SOLUTION

My solution for the design problem and the users’ concerns is to create a convenient on-the-go retail and education app named skingenious that helps the users:

  • Keep track of their skincare improvement on a daily basis, anytime, anywhere

  • Receive personalized skincare products and routine recommendations

  • Contact skincare experts for more in-depth solutions

  • Purchase skincare products right from the app with different sources of reviews without leaving the app

3. IDEATE

Before starting making any designs, I created a sitemap that helped me keep track of all of the different screens and visualize how they are all connected.

user flow charts.

After considering all the ways my users could navigate through the app, I came up with three red routes that are most essential and critical to the app to keep me on track when prototyping my design.

USER FLOW CHART 2: Completing  a Purchase

wire flows.

Wire Flow is a combination of wireframes and user flows. While user flows represent the screens that user will interact with while using the product, the wire flows below represent the places (states and actions) that my users will interact with the various components of the product.

4. PROTOTYPE & TEST

skingenious. wants to be perceived as knowledgeable and friendly like a companion. The images used will promote a healthy and caring beauty community.
The app is inspired by UI designs that are feminine, elegant, yet modern at the same time. Learning shouldn’t be boring. skingenious. want the users to have fun and be bold with their decisions by using bold emphasis when neccessary. To help users focus on the information, I would use neutral colors, a lot of white space, and UI elements with thin lines and basic shapes.

usability test &
retesting the iterated prototype.

I conducted Usability testing to understand the kinds of problems users might run into when interacting with the product design and how satisfied they would be with the product. I incorporated the feedback I received into my prototypes. 
Then, I conducted another round of testing, synthesized my work and iterated on my ideas.

The onboarding screens represent positive and friendly images that attract users’ attention. With large headings and short introductions on each screen, the users are educated about the app on a basic level.
On these screen, the users are encourage to tap “Get started” to go the next or “Sign In” if they are returning users.

CONCLUSION

skingenious. was my first hands-on UX/UI design project, where I gained invaluable industry knowledge while building the app. Throughout the process, I focused on the 5-step UX design method, always keeping the user at the center. Without conducting user interviews, gathering insights, and performing usability tests, this design wouldn’t have been as practical or effective.

​

Reflection: If I had the chance to redo this product or start a new one, there are a few areas I'd approach differently:

  • Be more time-focused: I’d manage my time more effectively, ensuring that each phase of the design process gets the attention it deserves.

  • Create more efficient animations: Spending more time on animation design would help streamline the handoff to developers and enhance the overall user experience.

  • Dive deeper into user interviews and usability testing: Due to time constraints, I felt I could have gathered more valuable insights. In future projects, I'll prioritize better time management to allow for deeper user research and more thorough testing.
     

Next Steps:

  • Incorporate mentor feedback: to refine and improve my portfolio.

  • Review Hiring Manager feedback: to align my work with industry expectations.

  • Manager Review, then making final changes to the app design and the portfolio
