Product Summary
"Hawaiian Tropic - Silk Hydration Lotion SPF 15" 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.
This moisturizer should also be hydrating enough to use without an additional moisturizer 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. The UV filters in this sunscreen are: oxybenzone 3.50% - 4.20%, avobenzone 3.00% - 3.70% and octocrylene 4.50% - 5.50%.

Moisturizing
What does the product description say?
Silk Hydration Lotion SPF 15
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, silk amino acids.
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, isopropyl myristate.
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
An emollient that helps soften the skin. Could be comedogenic
A non-drying alcohol. Works as an emollient. Helps water and oil mix together and creates a nice product texture
Might help attract water to the upper layer of the skin
Helps soften the upper layer of the skin
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 preserve products and creates a nice product texture
Prevents water loss from the skin surface and thickens the product consistency
Helps soften the upper layer of the skin and create a thicker product consistency
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
Helps attract water to the upper layer of the skin and can help improve skin barrier function
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.
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.
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
An umbrella term for the following three colorants: CI 77491, CI 77492, CI 77499. They might be able to offer some protection against visible light, but the degree of the protection is not clear
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
Anti-oxidation
Effective ingredients missing or their concentration is too low.
Helps to soften the upper layer of the skin and might have some anti-oxidant effect
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
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.
