31 Comments on SUNKILLER Perfect Strong Moisture [DISCONTINUED]

  1. Thank you!
    *and I ALSO LOVE reading your twitter

    I saw your other postbalso stating that it’s for everyday wear with a little of sweating; how little though? This is definitely more sweat resistant than let’s say the canmake gel?

      • Haha, I see. Thanks! Ah, it gets so hot here that the lets say minute you step out of a cool mall you start sweating. It’s basically summer 24/7 here! Would this be okay for that? Or do I need a waterproof sunscreen? Sunscreens tend to break me out and alcohol irritates me to high heaven. Sigh.

        • Depends on your skin and personal preference, really! This is a nice moisturising alcohol-free sunscreen for the price, but I personally wouldn’t go near it during Japanese summers.

          • Thanks!! Also I scanned the ingredients list and the difference is that an added slip agent butylene glycol is added into the 2nd ingredients and the extracts/ at the end have the orders changed.the actives are the same. What do you think if it?

            • That actually looks like a large English import sticker covering the original Japanese packaging. If that is the case, the English ingredient list is just plain wrong, simple as that. Japan requires cosmetics labelling to list ingredients in descending order of weight — my translation is identical to the original Japanese. There shouldn’t be any different.

            • English import sticker covering the original packaging? Okay I took a third glance and you’re right. It looks like something flimsy is beneath it. I’m confused though, are the ingredients really identical beneath that large import sticker or are the ingredients completely different. Did they just get the English printing wrong or what? Thanks a lot ratzilla! Your replies make me happy haha.

            • The English ingredient list on import stickers is wrong a lot of times. In fact, they’re usually wrong from what I’ve personally noticed. I’ve seen an entire shelf of shampoos (from different brands) in a supermarket all with identical English ingredient list, snack food with half the ingredients missing, etc.

              Countries require products to have ingredients and other product info provided to consumers in English (or whatever their language), but lax regulation means import companies can often get away with providing wrong info as long as it’s not reported.

              Japan adheres to the same global cosmetics labelling regulations as Canada, E.U & other countries (unlike Korean). Ingredients are shown in descending order of weight, so there shouldn’t be any difference when translated to INCI and exported.

  2. Is this good for sensitive skin and dry skin.
    I used biore sunscream but this dry My skin much more and i get more pimpels 🙁

    What is the best sunscream for dry and sensitive? I saw that the other sunscream have collegen etc but im now confused

  3. What is the best sunscream for sensitieve/dry skin?

    Im looking for a sunscream that have:
    no alcohol, no parfum, no silicone. Collegan, aloe-vera, moisturizer, and other good stuff.

    I have the: Biore sunscream spf 50. I dont like this sunscrram because it dry my skin more and more.

  4. Hi Ratzilla, I am sorry but I don’t understand why it says it is waterproof and sweat resistant if this is not meant for the outdoors…

    • Because in warmer weather, you can get still sweaty even just doing normal everyday activities (e.g. to and from school/work, shopping, running errands, etc.). It’s not formulated to protect skin for a day in the sun — that’s what Perfect Strong Plus (gold bottle) is for.

      • Thanks Ratzilla! I am so confused/torn. I have combination skin and don’t wear makeup, just a daily moisturizer, but I need a daily sunscreen to wear (that doesn’t feel heavy) since I am really prone to sun spots/freckles. I thought the the Sunkiller Perfect Strong Moisture would be the answer for daily running around and the Sunkiller Perfect Strong Plus N would be great for when I am playing outdoor sports, but since SK Perfect Strong Moisture is not mattifying, would you recommend Biore Aqua Rich watery essence instead? Or do you think the 2 SK products would be good? Initially, i didn’t like the idea of it since it contains alcohol and doesn’t resist sweating as well, but now I’m teetering since i also don’t want to look oily with the SK. Seems like the SK perfect strong Plus N would be a definite yes for outdoor sports, but what are your thoughts for everyday activities? Thanks so much!

        • Unless your skin is actually sensitive to alcohol, there’s absolutely no reason to avoid it. Alcohol in skincare can often be very beneficial as it enhances penetration, gives the product a lighter texture, and acts as a preservative! Unless your skin is dry, the Perfect Strong Moisture may be all the moisture your skin needs. The Biore UV Aqua Rich Watery Essence isn’t mattifying either and it’s not resistant to anything.

          You can certainly use sunscreens formulated for the outdoors/ sports just for normal everyday use. Some might find them too heavy duty and tenacious to be used daily, but oily skins can greatly benefit from these long-wearing formulas.

          • Thank you so much for your helpful and speedy response! Looks like the SK Perfect Strong Moisture (for daily running around) and SK Perfect Strong Plus N (for outdoor sports) should work well for me. I didn’t see this anywhere, but should I worry about the SKs clogging pores since I plan on using the SK moisture one daily?

            • That’s unfortunately is completely individual. I’d make sure you’re completely removing everything off your skin every night though.

          • Why do you say oily sking would benefit from the outdoor sunscreens if most find them heavy – I thought oily (in general) needs the lightest products. Anyway, this SK makes me a mess, breakouts and greasy skin is the result. I noted some of the ingredients in here are in other sscreens that made me breakout aswell but havent completely isolated them yet, so best to try with a question – which are the top 3-5 lightest sunscreens (either indoor or outdoor) and if the Kao milky line is anywhere close to it (or a a different brand that doesnt change the formulation each year – having a “safe heaven” sunscreen would make me a lot more open to trying new formulations lol)

            • There’s a wide range of sunscreens formulated for the outdoor/sports but they’re the most tenacious in general. Easy-on/easy-off sunscreens formulated for everyday wear are good and all, but most will not last on oily skin — the excess sebum will break it down in a flash.

            • Good to hear that I guess as it narrows the selection process as I can’t imagine reapplying protection just for accidental exposure..might vary, but is double cleansing required for outdoor/sports sunscreens?

    • Most definitely not, quite the opposite actually. This is moisturising (like the product name suggests) — it is not mattifying whatsoever. Not ideal for oily skin.

  5. Hi Ratzilla,
    I was wondering if you know how strict the PA ratings are? I was looking at the ingredients of Sunkiller and I know that Uvinul A plus is good for UVA 2 Rays– not so good for UVA 1. Octinoxate and Octocylene also not so good for UVA 1. Sadly, UVA 1 Rays are more plentiful and harmful. Sunkiller got PA++++ ratings, but do you think this is a trustworthy rating?

    Thanks again for your amazing website and recommendations.

  6. This is my first sunscreen that is resistant to both sweat, sebum and water, so that means that by applying it in the morning I’m good for the whole day regardless of swimming, sports, showering etc.? That’s pretty amazing considering the light and non-greasy texture it possess 🙂
