Product Summary
"Jack Black - Double Duty Face Moisturizer SPF 20" offers broad spectrum protection. It means that it protects from both UVA and UVB rays (you can remember UVB as "burning" sunlight - they cause sunburn. You can remember UVA rays as "aging" - they do not lead to sunburn, but they cause photodamage and contribute to early signs of skin aging and hyperpigmentation). On the negative side, the SPF of it is not high enough. We recommend to use a sunscreen with at least SPF 30 daily.
Because it includes good moisturizing ingredients, it can also work as a hydrating day cream.
Sunscreen filters
This sunscreen uses so-called "chemical", or organic UV filters (organic simply means that their molecules contain atoms of carbon). These filters typically give good sun protection and rarely leave a white cast, but they can be irritating for sensitive skin. Here are the exact UV filters in this sunscreen: avobenzone 2.20% (declared) and octinoxate 7.50% (declared).
Irritation risk
There are quite a few common irritants in this product, including ingredients without particular skin benefits. We would not recommend it for sensitive skin. We assess the overall irritancy of it to be high. For a detailed overview of all potential irritants: click here

Moisturizing
What does the product description say?
Double Duty Face Moisturizer SPF 20
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, sodium hyaluronate.
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, octyldodecyl neopentanoate.
One of the best moisturizing ingredients. Attracts water into the upper layer of the skin
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
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
Red algae extract that helps attract water to the upper layer of the skin
An emollient that helps soften the skin. Often used to stabilize other ingredients, for example, sunscreen
A silicone that helps improve the product texture and spreadability. Can absorb oil creating a short-term mattifying effect on 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
Used as a fragrance. Can be irritating
Can have some moisturizing properties due to its sugar content
Used mostly for creating emulsions - helping oil and water mix together. Helps soften the upper layer of the skin
Anti-aging
What does the product description say?
Contains potent antioxidants and vitamins, and offers broad-spectrum UVA and UVB protection to help shield skin from premature aging due to sun exposure.
Source: Ulta
This product does not contain ingredients that are able to reduce fine lines and wrinkles or help with skin elasticity, but it can improve the look of the skin temporarily through moisturization. Well-moisturized skin might also be able to repair the sun damage better.
The biggest anti-aging effect in this product comes from sun protection. Sun damage is the main factor causing early signs of skin aging. We, however, do not recommend using this product as a sunscreen because the protection it offers is not strong enough).
Three steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effect
Sun protection
This product offers broad spectrum sun protection, but it is weak. We recommend to use a broad spectrum sunscreen with at least SPF 30.
Avobenzone. An organic, or so-called "chemical" UV filter. Protects against both UVA and UVB rays. Needs to be combined with other filters in a formulation to be stable.
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
