I’m not totally sure what serum is actually supposed to do, I didn’t notice a big difference in my skin tone or texture really but I’ll still give it full stars since that’s probably on me and not actually a fault in the product, I will also probably need to try it out for longer than 10 days to actually see real results. It’s non-greasy, seemed to absorb fully in a few minutes and my skin did feel hydrated (I have oily skin so after a few hours I did have some visible oil buildup but no more than normal). It’s easy to use and limit cross-contamination because of the dropper. Read more

This serum has been a great addition to my routine. It feels very lightweight and soothing on the skin, and I’ve noticed less redness and irritation over time. The formula is simple but effective, especially if your skin needs calming and barrier support. Absorbs quickly and layers well with other products. Definitely something I’ll repurchase. Read more

This serum was really great, just lovely on the skin-- light and non-greasy. Did not break me out, felt beautifully silky on. It's hydrating but not sticky; I would say it's less hydrating than most Korean serums I've tried, not great for after shower, you may need to tone and moisturize after using this. I suffer from redness and I think this did appear to calm my skin. I think it also improved the texture of my skin, and helped it feel nice and smooth after application. It does have a scent but just barely, almost like light talc, It's so subtle that I honestly thought it had no scent at first. It's a very pleasant smell. Quality of the packaging is absolutely top notch, was surprised that the bottle is not only quite big but it's glass. I have another serum (PDRN) from this brand and that bottle was plastic so I was pleasantly surprised they made this one out of glass; it's very impressive and makes it feel like a high-end product. The eyedropper feels great quality too and dispensing the product is a breeze with the curved applicator. Overall I've been really pleased with the quality of the K-beauty brand TOSOWOONG, and would probably get more things from them. Not sure why some people are calling it an oil or serum oil, it doesn't say anywhere on the listing or bottle that this is an oil; it's clearly marked as a serum ampoule. Because this is a serum, of course it has no oily properties-- it has alcohol in it (3rd ingredient and also further down) so it's actually not oily at all... so if you are looking for a facial oil, give this a miss. The serum is yellow not because it's an oil but because of the Madagascar Centella and Turmeric in it. I liked that it has a small amount Turmeric because it's good as a natural anti-inflammatory, which also helps against redness. If you need lightweight soothing serum that reduces the appearance of redness, this is a good option for the price. I would get again. Read more

I've been really enjoying the TOSOWOONG Signature Ampoule. This really is a lovely serum. It has a light texture that absorbs quickly without any sticky residue, which makes it easy to layer with other products. What really stands out is how calming it feels—thanks to the 86%* Centella Asiatica extract & how my skin feels which is less irritated & more balanced (even when it's feeling extra fragile) & looks, which is great - even if I say so myself, lol. *The 86 on the bottle stands for the first 2 numbers in the parts per million of their main ingredient. In this case it's 860,048ppm Madagascar Centella Asiatica. This serum is absolutely gentle enough to use twice daily & I appreciate that it's made with clean natural ingredients. It's been great for keeping my skin hydrated throughout the day, giving it a healthy, natural glow. At just over $41, it's in the mid-price range for serums—well worth it for the quality, though it might give the budget-conscious a moment's pause. It is quite a large amount especially for a serum. Additionally, it's available as a Subscribe & Save option, which brings the cost down a bit & makes restocking more convenient. Note: Subscribe & Save items can be paused or cancelled at any time for any reason, with no penalty, no 'strings' attached. Read more
