SPF 50 · 3 UV filters

Broad spectrum

SPF 50Broad spectrumMineral + chemical filters

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.

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.

Butyloctyl SalicylateUVBA synthetic ester of salicylic acid that is used to help disperse pigments and boost effectiveness of sunscreen ingredients. It is able to absorb UV light (working as an organic, or chemical filter), but is not approved as a sunscreen ingredient on its own~5.8–7.1%

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~0.7–1.05%

Zinc Oxide Mineral UVBUVA Photo-stable A broad spectrum sunblock (protects from both UVA and UVB rays). Is suitable for most sensitive skins. In small concentrations, can be used as a colorant~12–15%

Moisturizing

Not advertised by the brand · 19 ingredients credited for this claim

Strong support

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, 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, peg-10 dimethicone.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide, panthenol

DimethiconeKey active· Emollient, OcclusiveEffect: HighA 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~1.5–1.9%

NiacinamideHeroEffect: HighIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production~1.2–1.4%

PanthenolHero· HumectantEffect: HighHelps attract water to the upper layer of the skin and can help improve skin barrier function~0.5–0.75%

Peg-10 dimethiconeKey active· Emollient, OcclusiveEffect: HighA silicone that works to soften the upper layer of the skin and reduce its water loss~0.75–1.1%

Dimethicone crosspolymerKey activeEffect: MediumUsed to create a thicker product texture. Helps soften the upper layer of the skin and might be able to prevent moisture loss from its surface~0.55–0.8%

AdenosineKey activeEffect: MediumMight help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)~0.3–0.55%

CyclopentasiloxaneKey active· EmollientEffect: MediumA silicone that helps improve the product texture and spreadability. Can absorb oil creating a short-term mattifying effect on the skin~3.9–4.7%

It can be itself be irritating though.~0.2–0.35%

Anti-blemish

Strong support

This product can help reduce breakouts and clogged pores because it contains the following ingredient: niacinamide. This ingredient is used for treating acne and can have a noticeable effect.

Anti-aging

Not advertised by the brand · 3 ingredients credited for this claim

Strong support

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains adenosine, niacinamide.

Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

This product can also 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.

NiacinamideKey activeEffect: HighIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production~1.2–1.4%

Product summary

We believe that "K-SECRET - Calamine Secret Sunblock" can provide reliable sun protection based on the ingredients listed. It can protect from both UVA and UVB rays. This is great news because 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).

It also works as a moisturizer, so you do not have to use an additional hydrating product. Like all broad-spectrum sunscreens, this product helps prevent early signs of aging.

Sunscreen filters

This is a "mixed" sunscreen in the sense that it uses both mineral and organic (so-called "chemical") sun filters. The organic filters in the product are: butyloctyl salicylate. As for the mineral filters, this sunscreen uses zinc oxide.

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 it to be medium. For a detailed overview of all potential irritants: click here
