FAQ

All your questions about the THE ONE SPF 50 Invisible Sunscreen Gel

Does this leave a white cast?

No, The One is the ultimate transparent sunscreen that has been tested on a sample of all skin tones (1 – 6) within the Fitzpatrick Scale with our advised quantity (½ a teaspoon for face and neck, or roughly 3 fingers’ worth) without leaving any white cast. Please see our before and after photos for assurance.

Can I wear it under makeup?

Yes, The One is not only a transparent, water-resistant broad-spectrum SPF 50 PA++++ sunscreen, it also works as a great primer for your makeup.

How often should I reapply The One?

Great question! We recommend that you apply The One liberally every morning (no matter the weather/season), 15 minutes before sun exposure and as needed. You should reapply: • 80 minutes of swimming or sweating • immediately after towel drying • at least every 2 hours when exposed to direct sunlight Warnings: For external use only. Do not use on damaged or broken skin. When using this product, keep out of eyes. Rinse with water to remove. Stop use and ask a doctor if rash occurs. Keep out of reach of children.

What does PA++++ mean?

This is a statement of the UVA protection – The One has the highest possible PA rating of PA++++ meaning your skin has high protection against UVA rays.

How much of The One should I use to receive maximum protection?

To receive the protection stated, The One should be applied generously with at least ½ teaspoon for face and neck (¼ for face and ¼ for neck). This is roughly equivalent to 3 finger-lengths worth. Sunscreen application is advised as “generously” to account for variances in people’s application and impressions of how much ¼ / ½ teaspoon actually is. Applying less sunscreen does not “lower the SPF number” but can drastically lower the overall protection of the sunscreen by providing incomplete coverage of the skin.

Why does it need to be applied every 2 hours?

Sunscreen protection gradually decreases over time once applied due to various factors. One of the most discussed is UV filters degrading as they absorb UV rays. However, sunscreen protection also diminishes due to more mundane factors such as the skin being touched; sunscreen being wiped off accidentally; and your skin going through its other natural processes such as sweating and shedding dead cells. These factors combined impact sunscreens’ ability to offer the full protection as stated, however your sunscreen will not “stop working” after two hours. We promise.

Is this a chemical or physical sunscreen? And what is the difference?

• The One is a chemical sunscreen. “Chemical” sunscreen is the popular name for Organic sunscreens / filters – organic in this case meaning being carbon-based chemicals, and not related to organic production/farming methods. • Likewise, “Physical” sunscreen is the popular name for Inorganic filters. These are also often called “mineral” filters. • In actuality, both types of sunscreens are chemicals and both are physical. Organic filters are a group of chemicals used as sunscreens which work mostly by absorbing UV rays and releasing the energy as heat. They offer additional benefits in sunscreen formulation including generally being the most cosmetically elegant due to most of them appearing transparent on the skin making them less likely to be seen on the skin, particularly more melanated skin. Inorganic filters also work by mostly absorbing UV rays, contrary to the belief that they work by reflecting the rays away and/or “physically” shielding the skin. Inorganic filters include zinc oxide and titanium dioxide and can make equally efficacious sunscreens, with the caveat that they will usually leave a “white cast” or chalky appearance on the skin when applied properly.

One of the most difficult parts of creating sunscreen formulas is making them work for many skin types and tones. The One Sunscreen Gel is one of the few sunscreens on the market that does just that and checks all of my boxes: high amounts of UVA and UVB protection, easy to spread on the skin, water resistant, completely transparent, hydrating but not greasy, and feels weightless on the skin but isn't drying. It feels incredibly comfortable on the skin – it doesn't feel like you're wearing sunscreen at all.

Love how it easily it absorbs into my skin. I originally bought it to use it only for my morning running because of its water resistance, but its quality has gotten me to use it more than just my exercises.
