The Facts About Sun Exposure

Being outdoor and basking in the bright, warm sun makes most people feel good, but it doesn't mean that you can ignore protecting yourself from the sunshine's side effects.


Introducing Sunpal

The idea is to have a product that works with a UV camera to help people do a much better job at sun protection.

Core Feature 1

Skin Scan

Offer a complete visibility into your skin condition and sunscreen coverage.

Core Feature 2

Personalized Timer

Give out a maximum sun exposure time recommendation based on your skin scan result.

Core Feature 3

Tracking & Analysis

Keep track of your sun exposure records.


Project Life Cycle

During the 8 weeks design process, I worked through a complete design circle from concept to interactive prototypes. I planned and carried out user surveys to understand the user base. I defined personas and maped the user journey to find out pain points and opportunities. During the ideation and prototyping phases, I designed and delivered wireframes, user flows, and prototypes. Using prototypes I can quickly perform usability tests, allowing me to iterate on my ideas/prototypes.


Online Questionnaire Survey

To better understand the user base, I planed and carried out a questionnaire survey, asking people’s thoughts and attitudes towards sun protection. A total of 58 people responded to my online survey.

Finding 1

People’s Major Concerns About Sun Exposure: Aging, Skin Caner, Skin Darkening and Sunburn

Among all the health risks associated with exposure to UV radiation, people’s top 4 concerns are: premature aging, skin cancer, skin darkening and sunburn.

Finding 2

Most People Choose Sunscreen As Their Primary Sun Protection Method

When talking about sun protection, applying sunscreen is the most popular method. 48 out of 58 survey participants chose sunscreen as the sun protection method they normally use.

Finding 3

People Are Aware Of The Importance Of Sun Protection And Are Willing To Spend Money On It

Over half of people who responded to the survey admit that sun protection is either important or very important to them, and they normally spend $0-$100 a year on sun protection products.
