Product Summary
"Hawaiian Tropic - Silk Hydration Weightless Sunscreen C" does not provide enough UVA protection. UVA rays do not cause sunburn, but still damage the skin, leading to early signs of aging and pigmentation issues.
It also works as a moisturizer, so you do not have to use an additional hydrating product.
Sunscreen filters
This sunscreen uses a mixture of both mineral and organic (so-called "chemical") UV filters. Here are the organic filters this product uses: oxybenzone, octinoxate, octisalate and octocrylene. As for the mineral filters, this sunscreen uses titanium dioxide.
Irritation risk
It 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 product to be high. For a detailed overview of all potential irritants: click here

What does the product description say?
Silk Hydration Weightless Sunscreen C
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:
panthenol.
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, isododecane.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol, paraffinum liquidum
Helps attract water to the upper layer of the skin and can help improve skin barrier function
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
Mineral oil. One of the most effective and well studied occlusive and emollient moisturizing ingredients. Helps reduce moisture loss in skin and repair skin barrier function
Helps soften the upper layer of the skin
An emollient that helps soften the skin and can decrease moisture loss. Helps create a nice product texture
A fruit extract that might help attract water to the upper layer of the skin. There is no evidence of other benefits in skin
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
Evens skin tone
This product contains ingredients () that could help reduce hyperpigmentation (for example, post-acne marks or age spots) in theory, but there is not enough evidence that they actually work.
The biggest effect for evening out skin tone in this product comes from sun protection. Sun damage is the main factor causing age spots, darkening of post-acne marks and other discolorations. This is why sun protection is the best strategy for maintaining an even skin tone. We, however, do not recommend using this product as a sunscreen because the protection it offers is not strong enough).
Sun protection
This product does not offer good protection against UVA rays.
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
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
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
Octinoxate. When used in higher concentrations, works as a sunscreen protecting the skin from UVB rays. When used in lower concentration, helps to preserve the product formulation. Is shown to be harmful to coral reefs - consider avoiding bathing in coral reef areas when wearing a product with this ingredient. It can be irritating
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
