Product Summary
"Piz Buin - Ultra Light Hydrating Sun Spray SPF10" "is a broad spectrum sunscreen meaning that it protects both from UVB rays (" burning "- they cause sunburn) and UVA rays (" aging "- they don't cause sunburn but lead to premature aging and pigmentation issues). However, this product does not offer enough sun protection. We recommend to use a sunscreen with at least SPF 30 daily.
Its formula is also hydrating, so you might not need an additional moistruizer during the day.
Sunscreen filters
This sunscreen uses so-called" chemical ", or organic UV filters (organic simply means that their molecules contain atoms of carbon). These filters typically give good sun protection and rarely leave a white cast, but they can be irritating for sensitive skin. Here are the exact UV filters in this sunscreen: oxybenzone 1.20% - 1.40%, tinosorb s 0.80% - 1.20%, avobenzone 2.20% - 2.70%, homosalate 4.00% - 4.90% and octocrylene 2.60% - 3.20%.
Irritation risk
This formulation includes some common irritants, including ingredients that do not provide a benefit for the skin. We assess the overall irritancy of this sunscreen to be medium. For a detailed overview of all potential irritants: click here

Moisturizing
What does the product description say?
Ultra Light Hydrating Sun Spray SPF10
Source: From product name
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, butylene glycol.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
A non-drying alcohol that works to soften the skin and stabilize product formulations helping oil and water mix together
Enhances the product texture and makes it more spreadable. Helps reduce water loss from the outer layer of skin. Extands the shelf life by preventing bacteria growth
Helps soften the upper layer of the skin and create a nice product consistency
Used to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin
An emollient that softens the skin and forms a protective layer on its surface. Helps water and oil mix together
Helps preserve products and creates a nice product texture
Used to preserve products, dissolve other ingredients and create a nice product texture
Anti-aging
What does the product description say?
Piz Buin Ultra Light Sun Spray SPF10 helps to protect the skin from the sun's rays with its enhanced UVA/UVB filters and it is also enriched with a strong anti-oxidant to prevent the skin ageing prematurely during sun exposure.

Sun protection
This product does not offer sun protection, or it is very low.
Avobenzone. An organic, or so-called "chemical" UV filter. Protects against both UVA and UVB rays. Needs to be combined with other filters in a formulation to be stable.
A weak sunscreen that protects against the sun rays that cause sunburn (UVB) and is somewhat effective against the UVA rays. It is quite stable and can help stabilize other, more vulnerable, sunscreen ingredients like Avobenzone. It is an organic, or so called "chemical" sunscreen
Tinosorb S. One of the most effective broad spectrum sunscreen ingredients. Protects from both UVA and UVB rays. It is photostable. Unfortunately, not approved by FDA (US) yet.
A weak sunscreen that offers some protection against the sun rays that cause sunburn (UVB), but does not offer meaningful protection against protect against the most aging sun rays (UVA). It loses its effectiveness quickly when exposed to sunlight. It is an organic, or so called "chemical" sunscreen. When used in low concentrations, helps to stabilize the product formulation
Same as oxybenzone. Protects in the UVB and short UVA range. In small concentrations, used to stabilize product formulation. Can be irritating. Is shown to be harmful to coral reefs - consider avoiding bathing in coral reef areas when wearing a product with this ingredient. It can penetrate the skin and get absorbed into bloodstream faster than other popular filters available in the US. The study that produced this finding did not address any potential health effects of the absorption
