Product Summary
We believe that "Jack Black - Sun Guard Sunscreen SPF 45" can provide reliable sun protection based on the ingredients listed. 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).
It should also be hydrating enough to use without an additional moisturizer during the day. This product prevents early signs of aging by protecting against sun damage (all broad spectrum sunscreens do that).
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 and octisalate. As for the mineral filters, this sunscreen uses zinc oxide.
Irritation risk
This formulation includes some common irritants, including ingredients that do not provide a benefit for the skin. We assess the overall irritancy of this product to be high. For a detailed overview of all potential irritants: click here

Anti-aging
What does the product description say?
Keeps your skin looking healthy and youthful.
Source: Walmart
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: retinyl palmitate.
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
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
What does the product description say?
Sun Guard Sunscreen SPF 45
Source: Walmart
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 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 soften the skin and reduce its moisture loss with emollients and occlusives: dimethicone, cyclopentasiloxane.
Keep in mind that this product does not contain effective ingredients to attract water to the upper layer of the skin. This is why an additional product with humectants like glycerin or hyaluronic acid can be helpful (apply it before this product for the best results).
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 silicone that helps improve the product texture and spreadability. Can absorb oil creating a short-term mattifying effect on the skin
Helps soften the upper layer of the skin and improve the product consistency
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
