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.

OctisalateEthylhexyl SalicylateUVBOctisalate. 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).

Evens skin tone
Not advertised by the brand · Retinyl palmitate
Strong 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).

Retinyl palmitateKey activeEffect: MediumThree 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~0.1–0.5%
Anti-aging
Not advertised by the brand · Retinyl palmitate, Ascorbyl palmitate
Strong evidence

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.

Ascorbyl palmitateEffect: LowBeing 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.~5.9–8.8%
Moisturizing
Not advertised by the brand · Dimethicone, Cyclopentasiloxane + 3 more
Good 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).

Product summary

We are worried that "Jack Black - Oil-Free Sun Guard Sunscreen Water Resistant SPF 45" 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 sunscreen 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 formulation includes some common irritants, including ingredients that do not provide a benefit for the skin. We assess the overall irritancy of it to be high. For a detailed overview of all potential irritants: click here

Price

The product retails for 126.05A$ in Australia and from 12.00$ up to 20.58$ in the United States.
