excellent sunscreen with skin loving ingredients, broad spectrum, great little container [SEP] The "Drop the Bomb" BBOSONG Suns stick uses one of THEE best UVA/UVB sunscreen ingredients on the planet: "Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine"! Say that 5 times fast. Or once. lol. It is a broad spectrum, highly photo stable, chemical sunscreen. Chemical sunscreens mean that they absorb rays and disperse as heat before they can reach skin and do damage. The SPF rating of 50+ and PA++++ means that it offers the highest amount of protection that a sunscreen can offer.<br /><br />Korean skin care, particularly sunscreens, can use super effective ingredients that products made in (or for) USA can not have because the governing bodies have not approved it. It is not because they are unsafe, but because there is a significant amount of bureaucracy involved. No new sunscreen ingredients have been approved in the USA in over 15 years, sad since there are so many wonderful innovations in the rest of the world. We lag greatly behind. Fortunately, we can still buy these products.<br /><br />The other sunscreen used in this product is, Ethylhexyl Methoxycinnamate (Octinoxate)- a less stellar chemical sunscreen that has mixed thoughts on its efficacy, safety, and desirability. It protects only against UVB rays and breaks down when exposed to light (10% per 30-40 minutes). However, when combined with another broad spectrum sunscreen, it compliments it very well.<br /><br />The third sunscreen component is, Octocrylene.  Screens out the UVB and somewhat in the UVA II range. It is quite photostable (loses 10% of SPF protection in 95 mins) and is often used to stabilize other photo-unstable UV-filters (octinoxate) It is also often used to improve the water resistance of the products.<br /><br />As for all the other ingredients- primarily stabilizers, viscosity controlling ingredients, hardeners-- basically all ingredients that make it a STICK than can glide onto the skin. It is formulated to melt into the skin on contact, and yet absorb thoroughly. Basically, you won't even know it is there.<br /><br />And like so many other Korean skin care items, there are ingredients that go above and beyond the basic sunscreen-- included are skin loving ingredients (emollients, skin conditioners, soothers) such as Japanese knotweed, water lily, gotu kola (centella asiatica), camellia japonica, Lespedeza Capitata Extract (anti inflammatory), scutellaria (ie scullcap/mint), green tea, licorice, rosemary, chamomile<br /><br />Has a super mild scent- clean, fresh almost like a deodorant, but subtle.<br /><br />Happens to be a in a container that reminds me of deodorant. Super small, cute. Stick in a pocket or purse. I happen to love using it on my hands. I am in my 40s, and while I have been using SPF most of my life on my face, I figured it was high time to remember to put some on my hands. I like keeping this in my purse or my car, and applying it when I go to drive. That seems to be the time that my hands are most consistently exposed to the sun. Figure, hands on the steering wheel and in front of a big window. So yeh, this is perfect for that.<br /><br />I have no problem using this on my face.  Doesn't grab skin when used over a moisturizer. If need be can be applied/emulsified in palms then patted on. I prefer it as my "reapply" SPF rather than my first application product (I am used to a cream style). When I do apply it to my face, I always run it over my lips. It is very silky, doesnt have a sunscreen flavor or feel, and it is adding much needed hydration and protection from the sun.<br /><br /> Again, I am in my 40s.. clear fair skin but with Rosacea (non acne- just redness and visible veins). Leans dry. Loves Korean skin care.<br /><br />This is so clear, so clean feeling, and so incredibly light that I wish I could show you how it doesn't even feel like anything is on. Not greasy, not even dewy. My skin feels bare.<br /><br />If I have any complaints, it is the use of fragrance. While it smells nice and doesn't really linger.. it would not make a top choice for use on my face. I do however like it for everywhere else and rather enjoy the light scent before it dissipates fully.<br /><br />Even so, it is a really good product, so far. If I experience anything else, I will be back to say so.<br /><br />For all the other ingredients, the each rate 1-2 (very low in terms of hazard to self or environment) on EWG Skin Deep Database.
