ISOI is a Korean skincare brand that touts itself as using natural products and " no harmful chemicals " (quote directly from the front page of the website). ISOI stands for "I SO Intelligent", and the main page of the ISOI site also encourages people to "Be an Intelligent Customer, and use isoi" and its "speed-effective natural skin care". And, the bestselling product from ISOI is its Bulgarian Rose Blemish Care Serum, which I'm reviewing today.Let me first say, the irony of encouraging people to be intelligent consumers while trashing "harmful chemicals" and promoting "natural skin care" in general is not lost on me. The fact is, as far as skincare is concerned, chemicals are not inherently bad, and not everything natural is automatically good. This is particularly the case for skincare, where the application is topical, as opposed to ingested, so while certain ingredients are good for the body when eaten, they might not have the same effect on skin. For example, even simple, natural things like lemon juice can be bad when applied to skin, because they are phototoxic could trigger skin reactions when exposed to sunlight after application , while certain "chemicals" like retinols, are good for skin.But that's just the marketing, and in a highly competitive market, brands will market themselves in whatever way sells best to the customer and gets their attention. And, the natural skincare trend has been blooming for awhile (as we've recently seen at BeautyAsia 2015 and other trade shows), and shows no signs of abating. And since I'm the kind of consumer who pays more attention to the ingredients list of the product than who the spokesperson for the brand is, I'm pretty much indifferent to how the product is marketed. So, marketing aside, how does the product fare?To answer that question, we'll start at my very favourite (and my very usual) place to begin a product review - the ingredients list!As you can tell from the ingredients list, the bulk of the product consists of water, humectants (Gycerin, Trehalose), Arbutin, which is the main active ingredient, and is found quite commonly in a lot of whitening ingredients, as well as Alcohol, which is there as a penetration enhancer, presumably for the Arbutin. Now I know alcohol is in there in a fairly high amount, being third on the ingredients list, and this might be a concern to some people. However, alcohol per se isn't necessarily bad depending on your skin, and as I've written in a previous blogpost for the Juju Aquamoist Moisture Lotion, another product with alcohol So, it really depends on your own skin. Generally, the oilier and thicker the formulation, the less a concern alcohol is, and the oilier your own skin, the less likely it will react to alcohol. I certainly wouldn't recommend anyone douse their skin in alcohol alone, but I feel the alcohol-is-bad scare on the Internetz isn't fully warranted, either. In this particular product, the alcohol is there as a penetration enhancer. But since the alcohol content appears to be fairly high, and since the product itself is not formulated to be very thick (mostly water and humectants and Arbutin), it is possible that for some skintypes that lean towards the dry, sensitive side, the alcohol in the product may be a concern.Other than that, there are a bunch of plant-derived extracts, most of which seem beneficial. Some of the plant extracts have anti-oxidant or anti-inflammatory effect to varying degrees (Scutellaria Baicalensis Root Extract, Paeonia Suffruticosa Root Extract, Glycyrrhiza Glabra (Licorice) Root Extract, Castanea Crenata (Chestnut) Shell Extract, Salix Alba (Willow) Bark Extract), some have anti-bacterial effects (Centella Asiatica Extract), but some of them are more questionable, and might pose sources of irritation (Rosa Damascena Flower Oil, which is fragrant but could be irritating). There are also some other functional ingredients like thickeners (Xanthan gum). On the whole, this product seems to be fairly straightforward in terms of formulation - primarily the humectants, Glycerin and Trehalose, and the actives Arbutin, and Alcohol the penetration enhancer, as well as various plant extracts, most of which seem to be helpful in one way or another. All in all, I'd say this is a fairly decently formulated serum, if you don't mind the alcohol, and it will probably be very light and weightless on the skin.My experiences with the ISOI Bulgarian Rose Blemish Care Serum were borne out by the ingredients list. The product smells very strongly of roses (I'm guessing from the Rosa Damascena Flower Oil), although the smell dissipates upon use. And the gel texture of the product, as expected, is very light and watery. And since it is formulated mostly with humectants, Arbutin and Alcohol, with very little emollient ingredients, it sinks into skin very fast and absorbs cleanly, and leaves behind no residue, making this ideal for layering under another moisturizer, or sunscreen, or makeup.When I used it, I found it to be somewhat helpful in managing my pimples - it seemed to help moderately, but then again, with blemish products, I never expect any miracles. I also found it more helpful at fading blemish marks and generally evening skintone than at managing active pimples, although it seems to help somewhat at preventing them from exploding on my face like they usually do. And I didn't find this particularly drying, despite the alcohol content. I also liked that the product was generally fuss free in terms of layering with other products - there aren't any polymers to interact with the next product you put on and ball up and peel off your face in little balls and bits, so generally, I found that the Bulgarian Rose Blemish Care Serum layered nicely under whatever moisturizer I chose to use it with. That's a little detail, but a very useful one - I get so annoyed when my skincare products don't play nice with each other and start peeling off my face, so it was nice to not have to worry with this.So, overall, would I recommend it? My main gripe with the product (other than the brand's marketing, which is a minor point for me) is probably the price - at SGD$92 for a 35ml bottle, this isn't the cheapest option around. In terms of value-for-money, I'll be frank and say that in my opinion, the ratio isn't the best, and $92 is a lot to pay for what you are getting. That said, I think this is best for those with oily skin, who have blemish concerns and want to fade some of their blemish marks or even out the skintone around that area, and are looking for a light, weightless serum to address that. This would also be worth checking out for those who are looking for a serum with arbutin that would layer under virtually any moisturizer or sunscreen (you can certainly use this even if you don't have blemishes for general whitening/brightening effects, too). However, those with dry or sensitive skins may find the product a bit harsh for them to use alone.
