Functionality & use
What is a sunscreen dispenser?
A sunscreen dispenser is a contact-free device that provides a measured dose of sunscreen in public or controlled environments.
They make SPF use quick, hygienic, and cost-efficient. Ideal for public usage and skin cancer prevention.
How does a sunscreen dispenser work?
Each Sundo dispenser is powered and can detect hand movement to dispense a preset amount of sunscreen.
Inside is a sealed bag of sunscreen , which keeps the formula clean and consistent, preventing contamination and waste.
How much sunscreen does one dispenser contain?
Depending on the model. The Smotspot dispenser contains 2.25 litres of sunscreen, the Solido can have 2.25 or 1.125 litres sunscreen, the Sundisp dispenser has a capacity of 1.125 litres of sunscreen.
Refills come in sealed, recyclable pouches for quick replacement and minimal waste.
What type of sunscreen is dispensed?
Clients can choose between their own sunscreen, or our own Sundo sunscreen (SPF30 ot SPF50, hypo-allergenic, UVa and UVb). The full ingredient list can be found on every dispenser.
Is power required to use the dispenser?
Yes, all dispensers are motion-activated and powered by:
- Solar energy (Smotspot)
- Rechargeable battery (Solido)
- Standard mains electricity (Sundisp)
Are the dispensers weatherproof and UV-resistant?
Yes. Smotspot housings are made from UV-stable ABS and coated aluminum, with sealed electronics to protect against moisture, dust, and sunlight.
All models are field-tested across Europe in varying climates.
Sampling, Customization & Branding
How can I use a dispenser for sunscreen sampling?
Place a branded Sundo dispenser in high-traffic areas (festivals, parks, retail stores or shopping streets).
Visitors test your sunscreen hands-free. Brands like NIVEA, La Roche-Posay, Avène, Louis Widmer, RAY all used our sunscreen dispensers for sampling their sunscreen effectively and without micropackaging.
Can I wrap or brand the dispenser with my logo or own design?
Absolutely. Every Sundo model can be fully wrapped in your campaign design or city branding. Turning health awareness into a visual activation.
Does Sundo offer creative activation options?
Yes, we support reflective coatings, custom shapes, and mobile bike units.
These options make Sundo a flexible tool for city marketing, festival partnerships, or CSR campaigns.
Can I collect data from the dispenser?
Yes, only for Smotspot dispensers. Each connected dispenser syncs with the Sundo online dashboard, allowing you to track:
- Number of uses
- Engagement by time and location
- Refill alerts
Data never includes personal information: only anonymized usage metrics.
Can I rent a dispenser for an event?
Yes. You can rent Sundo dispensers for short-term activations such as festivals, marathons, or municipal events.
Our logistics partners handle setup, refills, and removal.
What maintenance is required?
We offer complete installation, maintenance, refill and de-installation service if you rent a Smotspot dispenser. Maintenance effort for Solido and Sundisp is minimal. Sundo sunscreen dispensers are designed for plug-and-play operation.
Behavioral Science & Impact
Does data show that sunscreen dispensers actually increase sunscreen use?
Yes, and significantly.
A 2023 joint study between Sundo and KU Leuven found that adding behavioral nudges to public sunscreen dispensers increased daily sunscreen usage by 58%–274% across six Belgian locations. Even on days with high UV radiation, dispenser use spiked the most, showing that nudges are most effective when skin protection matters most.
We even won an award for our joint study and were able to present it during the European Social Marketing Conference in Ljubljana in 2024.
How can cities use behavioral nudging for public health?
Municipalities can integrate Sundo dispensers with nudging features to promote sunscreen use as part of their urban health and prevention policies.
The KU Leuven research showed that low-cost digital nudges, like live counters or environmental messaging, can lead to measurable improvements in community sun safety.
Incorporating dispensers in parks, beaches, and outdoor events helps reduce UV exposure, a leading cause of skin cancer and premature skin aging, while improving citizen well-being and city branding.
💡 According to the World Health Organization (WHO), 4 out of 5 skin cancers are preventable through consistent UV protection
Sunscreen dispensers for Out-of-Home Marketing and Brand Marketing
How can brands use sunscreen dispensers for out-of-home marketing?
Sundo sunscreen dispensers turn public health moments into brand touchpoints.
Unlike static billboards, our dispensers invite real interaction: people physically engage with your brand while applying sunscreen. This creates an emotional connection rooted in care and protection.
At major events, this interaction isn’t small-scale:
During Pukkelpop 2024, Lipton-branded dispensers generated over 54,000 sunscreen uses, directly linking the brand to safety, positivity, and summer fun.
Each dispenser doubles as a mini billboard with high dwell time, perfect for sponsors or FMCG brands looking to boost brand recall and positive sentiment.
Why is sunscreen distribution so effective for brand awareness?
Because it’s useful marketing.
Free sunscreen creates a positive exchange: you give something that genuinely helps people, and they remember your brand for it.
According to our internal research, people are 3.5× more likely to recall a brand that offered them something of real value versus one that simply advertised near them.
Moreover, Sundo’s out-of-home approach aligns with modern experiential marketing principles — merging CSR, visibility, and data:
- Every Smotspot dispenser provides engagement analytics (how many people interacted, when, and where).
- Brands can integrate sunscreen sampling into wider campaigns, linking to social media or QR-based activations.
- It’s a double-impact strategy: build awareness and contribute to public health.
