"Ren Skincare - Clean Screen Mineral SPF 30 Mattifying Face Sunscreen Broad Spectrum" uses a single UV filter (zinc oxide) in a relatively low concentration and might not be able to provide reliable sun protection.
It also works as a moisturizer, so you do not have to use an additional hydrating product.

Moisturizing
What does the product description say?
* Carob Seed Extract helps improve skin hydration, plumping and smoothing.

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, glucose.
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, helianthus annuus seed oil.
A great emollient due to its high linoleic acid content. One of the most effective plant oils in helping skin hydration and repairing skin barrier function
A good emollient. Contains various ingredients including vitamins and fatty acids that could work in the skin to neutralize free radicals and minimize moisture loss - if enough of these compounds is able to penetrate the skin in an active form.

Anti-aging
What does the product description say?
Get your essential daily protection to prevent premature ageing caused by sun exposure.

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.
This ingredient vaccinium macrocarpon seed oil might be able to help neutralize free radicals in skin and help it fight off some of the sun damage.
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).

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
