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.
“Moist Barrier Water Sun Milk M4”
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:
betaine, carnosine.
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: ceramide np, palmitoyl tripeptide-1.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: ceramide np, palmitoyl tripeptide-1
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains adenosine.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: carnosine, palmitoyl tripeptide-1.
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.
This product contains antioxidants (carnosine) 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 - ficus carica fruit extract, pinus pinaster bark extract also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.
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).

More about CyclohexasiloxaneA 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
More about Zinc oxideHelps soften the upper layer of the skin
More about Butylene glycol dicaprylate/dicaprateWorks 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
More about Titanium dioxideUsed 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
More about Butylene glycolA 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
More about Butyloctyl salicylateA type of silicone that helps create a nice product consistency and support the delivery of other ingredients
More about TrimethylsiloxysilicateA type of silicone that helps to soften the upper layer of the skin and create a nice product finish on the skin

More about NiacinamideHelps thicken the product consistency
More about Methyl methacrylate crosspolymerHelps oil and water mix together and works as an emollient
More about Stearic acidIs used to add opaque (non-transparent) appearance to formulations. Can be used to coat other ingredients for even dispersion. This is a different ingredient compared to the ones used in antipersperants (aluminium chloride and aluminium chlorohydrate)
More about Aluminum hydroxideUsed to stabilize mixtures of oil and water, and create thicker, gel-like product textures
More about Sodium chlorideA type of silicone that helps oil and water mix well together. Helps to disperse other ingredients, e.g. pigments, evenly in a formulation

More about PropanediolHelps to retain moisture by creating a protective barrier on the skin. Rich in fatty acids. Improves product texture and helps with the penetration of other ingredients.
More about Hydrogenated lecithinA plant extract that can help neutralize free radicals. The concentrations typically used in cosmetics are too small to have an effect
More about Ficus carica fruit extractA plant extract that has been shown to be able to reduce inflammation in skin, support restoration of skin barrier function, as well as support collagen production. Contains active compounds called centelloids: asiaticoside, madecasosside, asiatic acid and madecassic acid. Might be helpful in preventing stretch marks. It can be itself be irritating though.
More about Centella asiatica extractA plant extract that might help neutralize free radicals and reduce hyperpigmentation, but evidence of effectiveness of topical application is lacking. It can be an INCI name for the trademarked ingredient Pycnogenol (but could also be a different type of this plant's bark extract)

Based on the ingredient list, we assess that "DERMAFIRM - Moist Barrier Water Sun Milk M4" can provide 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).
This moisturizer should also be hydrating enough to use without an additional moisturizer during the day. Like all broad-spectrum sunscreens, this product helps prevent early signs of aging.
This sunscreen uses a mixture of both mineral and organic (so-called "chemical") UV filters. Here are the organic filters this product uses: butyloctyl salicylate. As for the mineral filters, this sunscreen uses both titanium dioxide and zinc oxide.
This moisturizer contains some common irritants, including those without a benefit for the skin. We assess the overall irritancy of this moisturizer to be medium. For a detailed overview of all potential irritants: click here
