My health and wellness is so important to me. That's why a product like Sunsei has changed my life. Not only does it have clean ingredients but it actually protects me from the sun as well. I feel so good about how I am taking care of myself and I do credit Sunsei for some of that.
We spend the whole summer on the lake with our grandchildren and are no longer comfortable with chemical sunscreens for protecting them. Sunsei is just what we were looking for; natural, safe without any bad chemicals like avobenzone and the others.
Love'd the sample! My girlfriend and I used it all day at the beach last weekend… went on smooth and rubbed right in clear!
I am dark skinned and white cast is an issue with zinc oxide and mineral sunscreens. This feels wonderful and goes on without the pasty white residue.
I love this sunscreen. It feels great on my face and I use it every day as my moisturizer!
Melanoma Story
Meet Mika. She is on a mission.
"My journey with Sunsei started with a wake-up call. An atypical spot on my right cheek tested positive for melanoma. It took 5 facial surgeries, 70 stitches and 24 topical chemo treatments before I heard I was cancer-free. I was in my mid-40s and had decades of bad sun habits behind me, but the diagnosis forced me to rethink everything I knew about skin health. I became an owner of Sunsei because I believe sunscreen should be more than something we remember on vacation; it should be a daily act of self-care and protection. I don't want anyone to go through the 15 months of hell I luckily lived through."

Frequently Asked Questions
Safe plant protection. For everybody, every day.
Yes - Sunsei uses zinc oxide as its only active and 100% plant-derived inactive ingredients, with no chemical UV absorbers, parabens, or synthetic preservatives. Soothing ingredients like aloe vera juice, jojoba, and shea butter make it well-suited for sensitive skin.
Yes. We use non-nano zinc oxide, which is gentler on your skin and on coral reefs. Our formula uses lightweight, low-comedogenic plant oils - jojoba, sweet almond, and coco-caprylate - that are well-tolerated by most skin types.
Yes. Zinc oxide has natural anti-inflammatory properties that may benefit acne-prone skin. We recommend patch testing if you have an active breakout or a specific skin condition.
Sunsei contains no oxybenzone or octinoxate - chemical UV filters that are restricted or banned in Hawaii, the U.S. Virgin Islands, and several other jurisdictions due to environmental and health concerns - making it well-suited for children 6 months and older. For infants under 6 months, we recommend sun avoidance and protective clothing over any sunscreen.
Sunsei contains no oxybenzone, avobenzone, or homosalate - chemical UV filters that are restricted or banned in several jurisdictions, including Hawaii and the U.S. Virgin Islands. Zinc oxide is widely considered one of the safest sunscreen actives during pregnancy but consult your healthcare provider as always.
Sunsei has completed FDA OTC product registration for SPF rating, broad-spectrum protection, water resistance, and product stability. All testing is conducted on live subjects.
Sunsei was born from a personal and professional belief that truly natural, plant-based mineral sunscreen - without the white cast, greasy feel, or questionable ingredients - was both possible and overdue. Our founders have been directly impacted by skin cancer, and that drives everything we do.
Sunsei is for health-conscious consumers who want to know exactly what they're putting on their skin - people who read ingredient labels, care about daily wellness, and want safe protection that works for every skin tone, every day.
Most "mineral" sunscreens on the market still contain chemical UV absorbers - what we call the Sunsei Suspects: oxybenzone, avobenzone, homosalate, octisalate, octocrylene, and octinoxate, among others. Sunsei is genuinely mineral-only, with 100% plant-derived inactive ingredients, no white cast, and easy spread ability. We believe in full ingredient transparency and don't hide behind glossy branding or vague label claims.
Sunsei has completed all FDA OTC product registrations, including SPF rating, broad-spectrum protection, water resistance, and stability testing.
The most common reaction is surprise - that a truly mineral sunscreen can go on this smoothly, with no white cast, and feel this light on the skin. Clean ingredients shouldn't mean compromised protection or comfort.
Yes. Zinc oxide is one of the few actives that naturally blocks across the full UVA and UVB spectrum. We don't add chemical filters to supplement zinc oxide the way many competitors do to make mineral claims - we use the highest zinc oxide concentration allowed by the FDA, which is 25%.
We currently offer two sunscreen products (and growing): SPF 30 and SPF 45. SPF 30 blocks approximately 96.7% of UVB rays, and SPF 45 blocks approximately 97.8% - a modest but meaningful difference. Beyond SPF 50, the added protection becomes marginal (well under 1%), which is why dermatologists generally treat SPF 30–50 as the effective, evidence-backed range for daily and active use.
Yes, Sunsei is water-resistant per FDA standards. Always reapply after swimming, heavy sweating, or toweling off, regardless of water resistance.
Reapply every two hours during sun exposure, or immediately after swimming or heavy sweating. For typical indoor daily use, a morning application is generally sufficient.
No. Our formulation has no white cast and is genuinely wearable across all skin tones.
Sunsei's lightweight lotion absorbs cleanly and provides a smooth base for makeup. Many users include Sunsei within their daily facial moisturizing routine.
Sunsei is designed for everyday use. UV exposure happens year-round, including on cloudy days and through windows. We believe sun protection should be a daily habit, not just a beach day routine.
Sunsei is a lightweight lotion that applies smoothly and spreads easily. Our formulation process creates a lotion that feels more like a cosmetic-counter product, noticeably different from the thick, balm-like texture of most mineral sunscreens. It won't leave a greasy feeling on your skin.
Yes and no. No, because zinc oxide is a sun blocker that sits on top of your skin rather than absorbing into it - it creates a barrier that blocks the sun's rays before they reach your skin. Yes, because our plant-based oil formulation absorbs quickly, delivering strong sun protection with no white cast.
Sunsei dries to a clean, comfortable finish - not greasy, not chalky. Most users find it closer in feel to a lightweight moisturizer.
Yes, the current formula includes a light fragrance. An unscented version is in development for those who prefer fragrance-free sunscreen.
No. Sunsei does not contain avobenzone or other chemical filters known to cause yellow fabric staining - a common complaint with chemical sunscreens.
Yes. Eliminating white cast and ensuring easy spread ability are core to our philosophy of creating an all-natural sunscreen that works for every skin tone. We built this product for everybody.
Yes. Sunsei is formulated for full-body use, including the face.
Yes. Our water-resistant formula and smooth-spreading texture make it practical for outdoor sports, water activities, and high-sweat scenarios like music festivals or family picnics.
Yes. Sunsei is available in a 3 oz (89 ml) size that meets TSA carry-on liquid requirements, by design.
Year-round! UV radiation is present every day, including cloudy days and winter, and is a leading cause of skin cancer and premature aging. Daily use is strongly encouraged.
Sunsei tubes are manufactured using 43% post-consumer recycled plastic. We continually monitor packaging advancements with a goal of making our product as environmentally friendly as possible. At present, there isn't a paper or other more sustainable material available that meets our product and quality standards. Stay tuned.
Yes. Our tubes are made of 43% post-consumer recycled material. Minimizing plastic and other environmentally harmful materials is core to our philosophy.
Yes. Sunsei's mineral zinc oxide formula does not contain oxybenzone or octinoxate - the two chemical filters most linked to coral reef damage and banned in several countries and U.S. states.
Sustainability is embedded in everything we do - we use plant-derived, naturally sourced ingredients and avoid the synthetic UV filters found in many conventional sunscreens. We view ingredient transparency and environmental safety as inseparable from everything we do.
Sunsei has a shelf life of two years when stored appropriately.
Store in a cool, dry place away from direct sunlight. Avoid leaving it in a hot car for extended periods.
Prolonged exposure to high heat can degrade the formula's consistency and efficacy. If the texture or scent changes noticeably, replace with a fresh tube.
