Product Summary
"Hawaiian Tropic - Island Sport Sun Lotion SPF 15" "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.
It also works as a moisturizer, so you do not have to use an additional hydrating product.
Sunscreen filters
This is a" mixed "sunscreen in the sense that it uses both mineral and organic (so-called" chemical ") sun filters. Here are the organic filters this product uses: avobenzone, octisalate, homosalate and octocrylene. As for the mineral filters, this sunscreen uses titanium dioxide.
Irritation risk
This sunscreen contains a bunch of common irritants, including ingredients that do not provide any known benefit for the skin. It might not be the best choice if your skin is sensitive. We assess the overall irritancy of this sunscreen to be high. For a detailed overview of all potential irritants: click here

Anti-oxidation
This product contains antioxidants (sodium ascorbyl phosphate) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.
A stable derivative of vitamin C. It is oil-soluble which means it is more likely to penetrate the skin compared to the pure form of vitamin C (which is water-soluble), but it is less bio-available and is way less effective in stimulating collagen and reducing wrinkles compared to the pure form of vitamin C (L-ascorbic acid) and its other derivatives (for example, magnesium ascorbyl phosphate). At the same time, this vitamin C derivative has been shown in studies to be effective in reducing acne, blemishes and clogged pores. It is less irritating then the pure form of vitamin C
Helps to soften the upper layer of the skin and might have some anti-oxidant effect
A fruit extract that might have some anti-oxidant effect
A great moisturising ingredient that softens the skin and reduces water loss from its upper layer. It also can be helpful in protecting skin from free radicals
A more stable but less bio-available form of vitamin E compared to Tocopherol. Might help moisturize and protect the skin from free radicals, but mostly used in low concentrations to stabilize other ingredients.
Moisturizing
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.
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, jojoba alcohol.
Helps soften the upper layer of the skin
Helps to soften the upper layer of the skin and might have some anti-oxidant effect
A silicone that improves product texture and helps dissolve other ingredients. Can form a non-greasy film on the skin to prevent moisture loss
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
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
A non-drying alcohol. Works as an emollient. Helps water and oil mix together and creates a nice product texture
Prevents water loss from the skin surface and thickens the product consistency
A fruit extract that might help attract water to the upper layer of the skin. There is no evidence of other benefits in skin
Helps soften the upper layer of the skin and create a nice product consistency
Helps attract water to the upper layer of the skin and can help improve skin barrier function
A great moisturising ingredient that softens the skin and reduces water loss from its upper layer. It also can be helpful in protecting skin from free radicals
Traditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin
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.
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
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 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
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
Works as a UV filter when used in high concentrations. It is photostable and is effective mostly against the UVB light, with some protection in the UVA range. In small concentrations, used for its ability to improve the color of cosmetic products. Is usually well tolerated by the skin
