Product Summary
We are worried that "BYBI - Day Defence SPF 30 Moisturiser" might not be able to provide reliable sun protection because it uses a single UV filter (zinc oxide) in a relatively weak concentration.
Because it includes good moisturizing ingredients, it can also work as a hydrating day cream.
Sunscreen filters
This moisturizer 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
This moisturizer contains actives that can be irritating. We assess the overall irritancy of this moisturizer to be low. For a detailed overview of all potential irritants: click here

About the brand
According to Cruelty-Free Kitty "BYBI" is cruelty free, but its parent company is not.
Anti-oxidation
This product contains antioxidants (tartaric acid) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.
An AHA (alpha-hydroxy acid). It oxidizes quickly which makes it less effective in skincare formulations. It can support skin's barrier and moisture levels
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
A polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in imporved hydration levels. It has been shown to be helpful against acne and clogged pores. Might help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals
Moisturizing
What does the product description say?
Day Defence SPF 30 Moisturiser
Source: From product name
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.
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: caprylic/capric triglyceride, shea butter ethyl esters.
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
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
Helps soften the upper layer of the skin

An AHA (alpha-hydroxy acid). It oxidizes quickly which makes it less effective in skincare formulations. It can support skin's barrier and moisture levels
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
Lecithin derivative. It helps oil and water mix together and can enhance penetration of other ingredients. It helps soften the upper layer of the skin
Helps products spread more easily and works as an emollient to soften skin
A polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in imporved hydration levels. It has been shown to be helpful against acne and clogged pores. Might help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals
An exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)
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
Sun protection
This product uses a single UV filter (zinc oxide) in a relatively low concentration and might not be able to provide a reliable sun protection.
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
