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). It loses its effectiveness quickly when exposed to sunlight. It is an organic, or so called "chemical" sunscreen~2.5–3.1%
HomosalateUVB Photo-stable A weak sunscreen that offers some protection against the sun rays that cause sunburn (UVB), but does not offer meaningful protection against protect against the most aging sun rays (UVA).

Titanium Dioxide Mineral UVBUVA2 Photo-stable Works as a UV filter when used in high concentrations. It is photostable and is effective mostly against the UVB light, with some protection in the UVA range. In small concentrations, used for its ability to improve the color of cosmetic products.

Anti-aging

Strong support

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: centella asiatica extract.

Centella asiatica extractKey activeEffect: MediumA plant extract that has been shown to be able to reduce inflammation in skin, support restoration of skin barrier function, as well as support collagen production. Contains active compounds called centelloids: asiaticoside, madecasosside, asiatic acid and madecassic acid. Might be helpful in preventing stretch marks. It can be itself be irritating though.~0.5–0.75%
TocopherolEffect: Low, below effective dosePure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself~0.3–0.55%

Can help calm down inflammation and has some anti-bacterial properties. Unfortunately, these antioxidants are unstable and lose their effectiveness very quickly in products. The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation~0.25–0.45%

Moisturizing

Good support

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, butylene 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, helianthus annuus seed oil.

Product summary

Based on the ingredient list, we assess that "Dr. Oracle - A-Thera Sunblock SPF 50" can provide reliable sun protection. We love that it can protect from both UVA and UVB rays (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 also works as a moisturizer, so you do not have to use an additional hydrating product. 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: tinosorb s, octinoxate, octisalate and homosalate. As for the mineral filters, this sunscreen uses both titanium dioxide and zinc oxide.

Irritation risk

This product contains some common irritants, including those without a benefit for the skin. We assess the overall irritancy of this sunscreen to be high. For a detailed overview of all potential irritants: click here
