Product Summary
We believe that "Dermaquest - SheerZinc SPF30" can provide reliable sun protection based on the ingredients listed. 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).
Its formula is also hydrating, so you might not need an additional moistruizer during the day. Like all broad-spectrum sunscreens, this product helps prevent early signs of aging.
Sunscreen filters
This product is a mineral sunscreen. It uses zinc oxide for sun protection. Zinc oxide almost never irritates the skin or stings eyes, but it can leave a white cast.
Irritation risk

Anti-aging
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.
These ingredients in the product might also be helpful for reducing and preventing fine lines, wrinkles, and skin elasticity, even though there is no conclusive evidence for their effectiveness: arabidopsis thaliana extract.
Plant extract that might be helpful in repairing sun damage but evidence of effectiveness in skin are lacking
The 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
Pure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself
Being a lipid soluble form of vitamin C, it is more stable and can penetrate the skin better than L-Ascorbic acid. It is effective in protecting the skin from free radicals, as well as evening the skin tone, but is less effective in stimulating collagen production compared to L-Ascorbic acid.
Anti-oxidation
This product contains antioxidants (polygonum aviculare extract) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).
The following ingredients - imperata cylindrica root extract also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.
A plant extract that contains a flavanol Juglanin. It can help neutralize free radicals in skin and reduce inflammation
A plat extract that might help neutralize free radicals in skin and attract water to its upper layer
Consists of remains of dead bacteria cells. Is likely helpful in attracting water to the upper layer of the skin. Might be helpful in reducing inflammation and neutralizing free radicals in skin. It is claimed to be a "DNA repair enzyme"
The 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
Pure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself
Being a lipid soluble form of vitamin C, it is more stable and can penetrate the skin better than L-Ascorbic acid. It is effective in protecting the skin from free radicals, as well as evening the skin tone, but is less effective in stimulating collagen production compared to L-Ascorbic acid.
Evens skin tone
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).
The 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
A salt derived from licorice. Works as an emollient to soften the upper layer of the skin and can help calm down inflammation. Might be helpful for skin lightening
Sun protection
This product offers a good level of protection against both UVB and UVA rays.
It is a mineral sunscreen. In other words, it contains non-organic UV filters. It will probably not sting your eyes but might leave a white cast.
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 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
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
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, imperata cylindrica root extract.
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, cetyl alcohol.
Helps attract water to the upper layer of the skin. Is often used to adjust the pH level of the product
Consists of remains of dead bacteria cells. Is likely helpful in attracting water to the upper layer of the skin. Might be helpful in reducing inflammation and neutralizing free radicals in skin. It is claimed to be a "DNA repair enzyme"
A plat extract that might help neutralize free radicals in skin and attract water to its upper layer
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
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
A non-drying alcohol that works to soften the skin and stabilize product formulations helping oil and water mix together
A silicone that helps improve the product texture and spreadability. Can absorb oil creating a short-term mattifying effect on the skin
Can help attract water to the upper layer of the skin
Used to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin
Helps soften the upper layer of the skin and create a nice product consistency
Used to create a nice product consistency
An emollient that softens the skin and forms a protective layer on its surface. Helps water and oil mix together
Helps soften the upper layer of the skin, dissolve other ingredients and create a thicker product consistency
Helps preserve products and creates a nice product texture
A silicone that serves as an emollient. Helps create a nice non-greasy feels
A good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin
A salt derived from licorice. Works as an emollient to soften the upper layer of the skin and can help calm down inflammation. Might be helpful for skin lightening
Pure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself
