Review title is weightless, non tacky, fully absorbs quickly, NO added fragrance, no scent [SEP] I have Rosacea, specifically type 1 where I experience redness from flushing and visible veins (telangiectasias). Otherwise clear skin. While topicals won't really help the veins, I can use products that help even out skin tone where it is pink from flushing. Some products can initially make my skin red, then it calms down (especially if new). This ISNTREE Cica Relief Ampoule Duo Set has not irritated my skin. In fact, it has helped to minimize aggravated skin.<br /><br />The serum is extremely light. I think the lightest weight product I have ever used. The bottles are small, and I feel like I am going through it quickly. I may be using too much, I dont know. I  do apply to neck and chest as well as face. I already use a product with EGF (epidermal growth factor), and I thought that maybe in serum form it would feel like a more concentrated dose. I have no idea how much Isntree uses, but this product feels like the emphasis is on the Centella Asiatica Extract. That isn't necessarily a bad thing, I am just not sure yet what I think about the performance of this product for my skin.  The two small bottles would be better as 1 bottle.<br /><br />--super light weight<br />--absorbs instantly<br />--not tacky<br />--skin feels instantly smooth (I also use some on the back of my hands)<br />--I wouldn't use it alone as a moisturizer, especially if have dry skin (like me)<br />--gentle, doesn't aggravate my skin, but that very well could differ for everyone (esp those w/ damaged skin barrier)<br />--contains soothing centella asiatica extract<br />--contains EGF- worth doing some research to see the benefits and to discount myths.<br />--ingredients that can help build and maintain skin barrier. Especially important for those with skin conditions where they are exacerbated by a damaged skin barrier. Got super sensitive skin? work on repairing that skin barrier before anything else.<br />--NO added fragrance in ingredient list. No naturally occurring scent either. I cant detect any aroma.<br /><br />My skin: mid 40s, smooth and clear (except for visible veins), leans dry. I follow this up with a moisturizing SPF (their sunscreens are great) or a moisturizer if using at night.<br /><br />I dont think it is bad. I really just think it is ok. I would give it 3.5 stars if I could. For me it isn't quite a 4 star product, so I am going with the middle of the road rating of 3. Your experience will vary. I think it would be especially appealing to those who prefer a weightless non tacky Centella Asiatica product. While I have zero issues with this, I am not likely to repurchase it. I have preferred products, especially for EGFs. However, if I notice anything else-- good or bad, I will be sure to update. It can take at least 2 weeks for a product to show its effectiveness, and it can take that long for the skin to acclimate to a new product. I am a little early on writing this, but my skin is used to centella asiatica as well as EGFs, and with some Isntree products.
