Product Summary
"Piz Buin - Moisturising Sun Lotion - Medium SPF15" offers broad spectrum protection. It means that it protects from both UVA and UVB rays (you can remember UVB as "burning" sunlight - they cause sunburn. You can remember UVA rays as "aging" - they do not lead to sunburn, but they cause photodamage and contribute to early signs of skin aging and hyperpigmentation). On the negative side, the SPF of this moisturizer is not high enough. We recommend to use a sunscreen with at least SPF 30 daily.
As a plus, this sunscreen uses some of the new generation UV filters (Tinosorb M). These filters are more stable and more gentle on the skin.
It contains good moisturizing ingredients and can double as a hydrating day cream.
Sunscreen filters
This is a so-called "chemical" sunscreen. It means that it uses organic UV filters. They typically offer good sun protection and rarely leave a white cast, but they can be irritating for some people with sensitive skin. Here are the exact UV filters in this sunscreen: tinosorb s 0.60% - 0.85%, avobenzone 1.60% - 2.00%, uvinul a plus 0.60% - 0.90%, octisalate 5.00% - 6.10%, tinosorb m 0.75% - 1.10% and octocrylene 3.60% - 4.40%.
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 moisturizer to be medium. For a detailed overview of all potential irritants: click here

Moisturizing
What does the product description say?
Moisturising Sun Lotion .
Source: From product name
This product can help improve hydration of the skin with the two types of ingredients.
The first type is called “humectants”:
these ingredients help attract water.
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. The following ingredients in this product do the job:
glycerin, butylene glycol.
This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: dimethicone, c12-15 alkyl benzoate.
A silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish
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 silicone that helps improve the product texture and spreadability. Can absorb oil creating a short-term mattifying effect on the skin
A non-drying alcohol. Works as an emollient. Helps water and oil mix together and creates a nice product texture
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
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
Helps preserve products and creates a nice product texture
A silicone that serves as an emollient. Helps create a nice non-greasy feels
Used to preserve products, dissolve other ingredients and create a nice product texture
Anti-aging
What does the product description say?
The advanced cream combines high level, broad spectrum protection with plant-derived antioxidant Feverfew PFETM, which helps improve cell tolerance to the sun and tackle premature skin ageing caused by sun damage and free radicals.
Source: Mankind
This product does not contain ingredients that are able to reduce fine lines and wrinkles or help with skin elasticity, but it can improve the look of the skin temporarily through moisturization. Well-moisturized skin might also be able to repair the sun damage better.
The biggest anti-aging effect in this product comes from sun protection. Sun damage is the main factor causing early signs of skin aging. We, however, do not recommend using this product as a sunscreen because the protection it offers is not strong enough).
Being a lipid soluble form of vitamin C, it is more stable and can penetrate the skin better than L-Ascorbic acid. It is effective in protecting the skin from free radicals, as well as evening the skin tone, but is less effective in stimulating collagen production compared to L-Ascorbic acid.
Sun protection
This product offers broad spectrum sun protection, but it is weak. We recommend to use a broad spectrum sunscreen with at least SPF 30.
This product can be considered "reef safe" because it does not contain the UV filters (oxybenzone and octinoxate) that can be harmful to coral reefs when present in the water in high concentrations.
Tinosorb M. A UV filter. Is effective against both UVA and UVB rays. It also provides some protection against visible light. It is photostable and can also be used to improve photostability of other sunscreen ingredients. Its physical properties help to create lightweight sunscreen formulations. It can leave a slight white cast. Unfortunately, it is not approved by the FDA (US) yet
Uvinul A Plus. A new generation broad spectrum sunscreen that offers an effective protection especially in the UVA range. It is stable in formulations. Unfortunately, is not approved by the FDA (US) yet
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.
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.
Octisalate. A UV filter. It offers some protection against the sun rays that cause sunburn (UVB), but does not 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
Used to improve the product adherence to the skin, for example, to pro-long the protective effect of sunscreens. Can be irritating to very sensitive skin
