Product Summary
We assess that "Sun Bum - Signature SPF 50 Sunscreen Lotion" can provide reliable sun protection based on the ingredient list. 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).
Its formula is also hydrating, so you might not need an additional moistruizer during the day. Like all broad-spectrum sunscreens, this product has an anti-aging benefit.
Sunscreen filters
This is a "mixed" sunscreen in the sense that it uses both mineral and organic (so-called "chemical") sun filters. Here are the organic filters this product uses: octinoxate, octisalate and octocrylene. As for the mineral filters, this sunscreen uses zinc oxide.
Irritation risk
There are some common irritants in this product, including ingredients that do not have benefits for the skin. We assess the overall irritancy of this moisturizer to be medium. For a detailed overview of all potential irritants: click here

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.
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
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).
Sun protection
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.
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
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
Octinoxate. When used in higher concentrations, works as a sunscreen protecting the skin from UVB rays. When used in lower concentration, helps to preserve the product formulation. Is shown to be harmful to coral reefs - consider avoiding bathing in coral reef areas when wearing a product with this ingredient. It can be irritating
Octisalate. A UV filter. It offers some protection against the sun rays that cause sunburn (UVB), but does not protect against the most aging sun rays (UVA). It loses its effectiveness quickly when exposed to sunlight. It is an organic, or so called "chemical" sunscreen
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:
sodium hyaluronate, aloe barbadensis leaf 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: beeswax, butyrospermum parkii butter.
Forms a protective barrier that holds water and keeps dry skin hydrated. Keeps an emulsion from separating into its oil and liquid components, and increases the thickness of a product. Can be an allergen
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
One of the best moisturizing ingredients. Attracts water into the upper layer of the skin
Enhances the product texture and makes it more spreadable. Helps reduce water loss from the outer layer of skin. Extands the shelf life by preventing bacteria growth
Used to soften the upper layer of the skin and create a thicker product consistency
Non-drying alcohol that helps water and oil mix together. Also serves as an emollient
Helps soften the upper layer of the skin. At the same time, it can weaken the skin's barrier enhancing penetration of other ingredients and increasing the risk of skin dryness
Helps attract water to the upper layer of the skin and improves the product texture
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
Helps attract water to the upper layer of the skin and can help improve skin barrier function
Used mostly for creating emulsions - helping oil and water mix together. Helps soften the upper layer of the skin
