Keysun Clear Zinke is a clear zinc sunscreen, SPF 30+, in a 50g tube, water resistant for 4 hours. Zinc protection without the opaque white stripe, which is the reason people buy it.
Why Keysun Clear Zinke is a clear zinc
Traditional zinc sits on the skin as a visible layer. That is exactly what makes it effective and exactly what stops people wearing it. A clear zinc formulation gives you a zinc-based product that goes on without the white mask, so it gets used on a work site or a boat where a coloured stripe would not.
The trade is honest: a clear formulation is less conspicuous, which also means it is harder to see where you have missed. Apply methodically rather than by eye.
Four hour water resistance, read properly
Water resistant for 4 hours means it has been tested to hold its SPF through water immersion for that period. It does not mean four hours of protection regardless of what you do. Towelling off removes sunscreen, and so does sweat and abrasion under clothing or a harness.
Reapply after towel drying, after heavy sweating, and at least every two hours of continuous sun exposure, whatever the water resistance rating says. Water resistance describes durability in water, not how long the protection lasts.
Using enough Keysun Clear Zinke
The most common reason sunscreen underperforms its SPF is that people apply too little. A 50g tube is a personal-sized tube, not a season’s supply, and the full-body adult application is roughly a teaspoon per limb, per front, per back and for the face and neck. Apply it before going out, not once you are already in the sun.

Keysun Clear Zinke FAQs
What SPF is Keysun Clear Zinke?
SPF 30+, in a clear zinc formulation, water resistant for 4 hours. The 50g tube is the personal carry size.
Is it really clear, or does it go white?
It is a clear zinc formula, so it does not leave the opaque white layer of traditional zinc cream. The flip side is that you cannot see where you have missed, so apply deliberately rather than checking by eye.
How often do I reapply it?
At least every two hours in continuous sun, and again after towelling off, heavy sweating or anything that rubs it away. The 4-hour water resistance describes how it holds up in water, not how long you are protected.
What does 4 hour water resistant actually mean?
That it has been tested to maintain its stated SPF through water immersion for that time. It does not survive towel drying, which removes sunscreen mechanically regardless of the rating.
How much should I use?
More than most people do. Roughly a teaspoon each for the face and neck, each arm, each leg, the front and the back. Under-application is the main reason a sunscreen delivers less than its labelled SPF.
Is it suitable for outdoor work?
That is largely what it is for. Clear zinc with 4-hour water resistance suits site work and water-based activity where visible zinc is impractical. Reapply through the day rather than relying on a morning application.
Always read the label and use only as directed. Sunscreen is one part of sun protection alongside clothing, hats and shade. Avoid prolonged sun exposure. This information is a general guide and is not medical advice.
