This product offers a good level of protection against both UVB and UVA rays.

This sunscreen uses organic (so-called "chemical") sunscreen filters. Organic, or "chemical" filters usually provide reliable sun protection and rarely leave a white cast. Sunscreens with organic filters can sting eyes.

OctocryleneUVB Photo-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~5.2–6.3%
OxybenzoneBenzophenone-3UVBUVA2Same 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~3.6–4.4%
Titanium Dioxide Mineral UVBUVA2 Photo-stable 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~0.1–0.2%
AvobenzoneButyl MethoxydibenzoylmethaneUVA1Avobenzone. 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.~4.5–5.5%

Not advertised by the brand · Ascorbic acid, Retinyl palmitate
Strong evidence

This product offers broad spectrum sun protection. It means that it can prevent hyperpigmentation and help keep the skin tone even (sun damage is the main factor causing age spots, darkening of post-acne marks and other discolorations).

Ascorbic acidUnder-dosedEffect: HighThe most well-researched antioxidant that works in skin. Helps neutralize free radicals supporting collagen production, helping to even out the skin tone and preventing early signs of aging~0.25–0.45%
Retinyl palmitateUnder-dosedEffect: MediumThree steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effect~0.3–0.55%

This product can help prevent early signs of skin aging because it offers a good level of broad spectrum sun protection. Sun damage is the main cause of premature skin aging, and protecting your skin from the sun is the best anti-aging strategy.

Good evidence

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, caprylyl 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, cetearyl alcohol.

PolymethylsilsesquioxaneKey activeEffect: HighA silicone that improves product texture and helps dissolve other ingredients. Can form a non-greasy film on the skin to prevent moisture loss~0.7–1.1%

Product summary

Based on the ingredients included, we believe that "Hawaiian Tropic - Satin Protection Ultra Radiance Sun Lotion SPF 50" can offer reliable sun protection. We love that it can protect from both UVA and UVB rays (not all sunscreens with SPF ratings give UVA protection. UVA rays do not cause sunburn, but still damage our skin and lead to early aging).

Because it includes good moisturizing ingredients, it can also work as a hydrating day cream. Like all broad-spectrum sunscreens, this product helps prevent early signs of aging.

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, avobenzone and octocrylene. As for the mineral filters, this sunscreen uses titanium dioxide.
