Diethylamino Hydroxybenzoyl Hexyl Benzoate (DHHB) is a chemical UVA absorber. It is formulated for high UVA protection (320-400 nm) and photostability.
DHHB has been approved by the EU, Japan, Taiwan, and South America for use up to 10%.
UV absorbers are an agent that absorbs UV rays. They protect your skin by using chemical reactions to convert UV rays into heat and energy.
UV rays are a form of electromagnetic radiation from the sun. Other sources include tanning beds and welding torches. Radiation is the emission of energy. UV Rays are divided into 3 groups. UVA (320-400 nm) contains the least amount of energy. They are linked to long term skin damage such as wrinkles and hyperpigmentation. UVB (290-320 nm) rays emit more energy than UVA rays. They are capable of damaging DNA in skin cells. UVB causes sunburns and are thought to be linked to skin cancer. UVC (200-280 nm) contains the highest amount of energy. Our ozone blocks UVC. UVC can also originate from welding torches, mercury lamps, and sanitizing bulbs.

Polymethylsilsesquioxane has not been shown to clog pores. It has been deemed safe to use up to 55%, but most cosmetics use much less.
If you have concerns about using this ingredient, we recommend speaking with a professional.

Other benefits include smoothing wrinkles and minimizing redness.
The cherry on top? Niacinamide can also help build keratin, a protein that keeps skin firm.
When incorporating niacinamide into your routine, look out for concentration amounts. Typically, 5% niacinamide provides benefits such as fading dark spots. However, if you have sensitive skin, it is better to begin with a smaller concentration.
Niacinamide can be mixed with other ingredients to boost benefits. For instance, it has shown to be effective when used with copper, folic acid, and zinc to treat acne.

Tromethamine is an aliphatic compound. An aliphatic compound is an organic compound with open-chained carbon atoms. It is synthetically created. Tromethamine is used to balance pH and improve texture.
As an emulsifier, Tromethamine prevents oil and water ingredients from separating. This helps stabilize the product and elongate a product's shelf life. Tromethamine also makes a product thicker.
Tromethamine helps balance the pH level of a product. Normal pH level of skin is slightly acidic (~4.75-5.5). The acidity of our skin is maintained by our glands and skin biome. Being slightly acidic allows our skin to create an "acid mantle". This acid mantle is a thin barrier that protects our skin from bacteria and contaminants.
Oral Tromethanmine is an anti-inflammatory drug but plays the role of masking, adding fragrance, and/or balancing pH in skincare.

Tocopherol (also known as Vitamin E) is a common antioxidant used to help protect the skin from free-radicals and strengthen the skin barrier. It's also fat soluble - this means our skin is great at absorbing it.
Vitamin E also helps keep your natural skin lipids healthy. Your lipid skin barrier naturally consists of lipids, ceramides, and fatty acids. Vitamin E offers extra protection for your skin’s lipid barrier, keeping your skin healthy and nourished.
Another benefit is a bit of UV protection. Vitamin E helps reduce the damage caused by UVB rays. (It should not replace your sunscreen). Combining it with Vitamin C can decrease sunburned cells and hyperpigmentation after UV exposure.
You might have noticed Vitamin E + C often paired together. This is because it is great at stabilizing Vitamin C. Using the two together helps increase the effectiveness of both ingredients.
There are often claims that Vitamin E can reduce/prevent scarring, but these claims haven't been confirmed by scientific research.

I JUST LOVE IT! ROUNDLAB PLEASE I AM BEGGING YOU SELL THIS PRODUCT IN GREECE
from GabriellaTsoukalasto me, this sunscreen feels pretty much identical in terms of texture and finish to the wonderful Beauty of Joseon sunscreen, so suffice to say, i love this one as well. however, if the Beauty of Joseon sunscreen caused problems for you, then i would not recommend this. the only difference to me is that this sunscreen has a slight scent, presumably from one of the plant extracts (i’m not smart enough to pinpoint which one it could be). i only smell it when applying the sunscreen; it doesn’t ...
from screamadelicaI absolutely love this product. I found it on IG via MySkinIsGlass's page, and he said it was great for oily skin, and I gave it a try. I love it, it's light weight, and leaves 0 white cast!! No acne or problems with my skin after using it. It's my go-to sunscreen.
from LocalNewYorkerSKIN1004 Madagascar Centella Hyalu-Cica Water-Fit Sun Serum SPF50+ PA++++ 42 ingredients
Amazing sunscreen, feels so lighweight and not greasy and oily at all. Did not worsen my oiliness and did not make me breakout. Wen I first started using it around my eyes it kinda stund but it doesn't anymore
from CentellaAddictAfter using so many sunscreens I found the one! The texture is super lightweight, moisturizing without any white cast, has a little weird smell and burnt my eyes but it faded away after couple seconds. Left my skin moisturized and like it was nothing on it and it’s so affordable! Recommend hundred times
from HubayobiI've tried so many sunscreens and every single one has burned my skin. this one only burns around the nose and eyes, but sometimes it doesn't. I don't really know but it might be the alcohol?! the BOJ burns way more so I'm using this one atm. Have yet to find one that won't irritate my skin T_T but yes otherwise it has a nice consistency and doesn't leave a whitecast.
