Product summary

We assess that "Beauty of Joseon - Relief Sun Mini" can provide reliable sun protection based on the ingredient list. 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).

As a plus, this sunscreen uses some of the new generation UV filters (Tinosorb M). These filters are more stable and more gentle on the skin.

Its formula is also hydrating, so you might not need an additional moistruizer during the day. Like all broad-spectrum sunscreens, this product has an anti-aging benefit.

Sunscreen filters

This is a so-called "chemical" sunscreen. It means that it uses organic UV filters. They typically offer good sun protection and rarely leave a white cast, but they can be irritating for some people with sensitive skin.

Sun protection

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.

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.

Product claims breakdown

Moisturizing

7 ingredients contribute at the levels below

Strong evidence

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, saccharomyces/rice ferment filtrate.

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. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide

NIACINAMIDERole: HeroIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production~1.6–2%

ADENOSINERole: Key activeMight help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)~0.25–0.45%

GLYCERINRole: Key activeOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~0.6–0.95%

POLYMETHYLSILSESQUIOXANERole: Key activeA silicone that improves product texture and helps dissolve other ingredients. Can form a non-greasy film on the skin to prevent moisture loss~2.3–2.9%

SACCHARUM OFFICINARUM EXTRACTRole: Key activeSugar extract that helps attract water to the upper layer of the skin~0.2–0.35%

TOCOPHEROLRole: Key activePure 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~0.25–0.5%

CAMELLIA SINENSIS LEAF EXTRACTRole: Key activeCan contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals. 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%

Anti-aging

Brand does not advertise this — the formula does

Quiet bonus

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains adenosine, niacinamide.

Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

This product can also 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.

TOCOPHEROLRole: Key activePure 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~0.25–0.5%
