Sun protectionSPF 50 · 2 UV filtersBroad spectrum
This product offers a good level of protection against both UVB and UVA rays.
It is a mineral sunscreen. In other words, it contains non-organic UV filters. It will probably not sting your eyes but might leave a white cast.
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.
Anti-aging3 ingredients credited for this claimStrong support
“This multilayer formula is enriched with broad spectrum mineral sunscreen, proprietary Infrared and HEV Protection Complex, antioxidants and DNA repair enzymes to shield skin from environmental elements that can be harmful, such as free radicals, pollutants and the damaging effects of sun radiation and high-energy visible (HEV) blue light from everyday electronics.”
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: arabidopsis thaliana extract, carnosine.
Moisturizing22 ingredients credited for this claimStrong support
“DNA Repair, Infrared + HEV Protection, Antioxidant Repair, Hydration Next generation sunscreen.”
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:
carnosine, caprylyl glycol.
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, methicone.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: ceramide ap, ceramide eop, ceramide np, phytosphingosine
Anti-oxidationNot advertised by the brand · 7 ingredients credited for this claimStrong support
This product contains antioxidants (carnosine, superoxide dismutase) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).
Evens skin toneNot advertised by the brand · No ingredient credited for this claimStrong support
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).

Product summary
We believe that "PRIORI Skincare - TETRA fx251 Broad Spectrum SPF50 Sunscreen Color Guide" 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).
This moisturizer should also be hydrating enough to use without an additional moisturizer during the day. Like all broad-spectrum sunscreens, this product has an anti-aging benefit.
