Sun protectionSPF 45 · 3 UV filtersBroad spectrum
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.
Anti-agingRetinyl palmitate, Ascorbyl palmitateStrong evidence
“Keeps your skin looking healthy and youthful.”
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.
Evens skin toneNot advertised by the brand · Retinyl palmitateStrong evidence
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).
MoisturizingNot advertised by the brand · Dimethicone, Cyclopentasiloxane + 3 moreGood evidence
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).

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

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).
