   This stuff works!
   I am a fan of this face serum. I got the one for rosacea. It seems to have gotten worse since I had a hysterectomy. I noticed within a couple of weeks the reduction of redness that went across my nose to each side of my cheeks. I also developed acne after the hysterectomy. I found another product to help with that but it left me with lots of little scars around the nose and mouth area. These seem to be getting lighter over time but I plan to give it the full eight weeks of recommendation to determine if that is accurate. I read what Rufus had to say. It clearly states that the application will feel sticky until it dries and it does just that. I wait a couple of minutes after applying it to add moisturizer and I only use it at night because of the increased sensitivity to sun, according to Rufus. I did not ever have any kind of skin irritation and I had not read what Rufus had to say about the application process. I had been using way more than the two to three drops of serum to start with and building up to five. I have been slapping this stuff on irresponsibly! LoL Thankfully, I did not have any kind of negative reaction. For what it does, I found it reasonably priced. Because what it does… is that it works if used correctly and having reasonable expectations.

   Good product, take a chance and buy this.
   This helped my sensitive, and very allergic to everything skin. I would buy it again. Most of the time I react immediately to facial products, but I did not to this one. You only need a very, very small amount. It toned down the red in my skin, kept breakouts down, gave my skin some moisture, it feels silky but it is not oily and absorbs immediately. I was pleasantly pleased with this product. I am a senior.

   Soothing Azelaic Serum with Centella and Floral Scent (Ingredients Listed)
   TOSOWOONG’s Azelaic Acid Face Serum is a calming, gel-like formula designed to reduce redness and hydrate irritated skin. With a pale green hue and a floral scent, it delivers a cooling, soothing experience that feels gentle and restorative. While the dropper design is unconventional, the serum itself is well-formulated and effective for sensitive or reactive skin.My serum arrived in a box about 1½ inches square and just under 4 inches tall. Inside was a matching clear acrylic bottle filled with pale green liquid. The dropper has a curious twist—literally—with a 60° bend at the tip. I initially thought it was a defect, but the Amazon listing confirms it’s intentional. I’m still unsure of its purpose, as it doesn’t seem to improve functionality. Branding is clean and consistent with mid-tier K-beauty—simple, clinical, and shelf-friendly.Ingredients are listed on the box and included at the end of this review. The formula centers on azelaic acid, a well-known anti-inflammatory and brightening agent that helps calm redness and fade post-acne marks. It’s supported by niacinamide for barrier support and oil control, panthenol and allantoin for soothing, and a full suite of Centella actives—madecassoside, asiaticoside, asiatic acid, and madecassic acid—for calming and repair. The serum also includes multiple forms of hyaluronic acid for hydration, squalane for lightweight emollience, and zinc PCA for sebum regulation. Rosa centifolia flower water adds a gentle floral scent, while melia azadirachta (neem) extracts and bacillus ferment offer antioxidant and microbiome support. The texture is built around glycerin, propylene glycol, and hydroxyethylcellulose, giving it a gel-like consistency that spreads easily and absorbs well.Directions suggest using the serum to soothe redness and deliver deep hydration. I applied it nightly for over a week, focusing on areas prone to irritation. The serum dispenses as a light green gel with a soft floral scent—pleasant and not overpowering. It feels cool and soothing on the skin, and non-occlusive. Repeated use noticeably calmed irritation and reduced redness. While I didn’t see dramatic brightening, the overall tone and texture of my skin felt more even and less reactive.At $25 for 33 ml, this serum is slightly above average for K-beauty pricing, but the ingredient profile and performance justify the cost. It’s a well-balanced formula for sensitive skin, especially if you’re looking to calm inflammation and hydrate without heaviness. My rating: 4 stars.INCI (Ingredients Listed): Water, Rosa Centifolia Flower Water, Azelaic Acid, Propylene Glycol, Dipropylene Glycol, Methylpropanediol, Hydroxypropyl Cyclodextrin, Glycerin, 1,2-Hexanediol, Disodium Phosphate, Maltodextrin, Butylene Glycol, Hydroxyethylcellulose, Panthenol, Ethylhexylglycerin, Melia Azadirachta Leaf Extract, Alcohol, Allantoin, Dipotassium Glycyrrhizate, Niacinamide, Tris (Tetramethylhydroxypiperidinol) Citrate, Melia Azadirachta Flower Extract, Beta-Glucan, Arginine, Citric Acid, Squalane, Zinc PCA, Polysorbate 60, Sodium Phosphate, Caprylic/Capric Triglyceride, Hydrogenated Lecithin, Madecassoside, Asiaticoside, Sodium Hyaluronate, Asiatic Acid, Madecassic Acid, Centella Asiatica Extract, Ceramide NP, Cholesterol, Bacillus Ferment, Centella Asiatica Flower/Leaf/Stem Extract, Centella Asiatica Leaf Extract, Centella Asiatica Root Extract, Lactobacillus Ferment, Oleic Acid, Palmitic Acid, Stearic Acid, Hyaluronic Acid, Hydrolyzed Hyaluronic Acid, Hydrolyzed Sodium Hyaluronate, Sodium Hyaluronate Crosspolymer, Pentylene Glycol.

   Azelaic Acid Face Serum
   Really good for sensitive skin! Helps with redness & my rosacea. Unscented, which is important for my allergies. Really absorbs into my skin, making it feel softer & moisturized.

   Not as good as I hoped
   It makes my skin feel tight, but other than that, I see no difference before or after, and I have been using for 2 months. It does leave my skin extremely dry, and I have to use a cream after. Did not help with lines, or dark spots.

   Very good 10% azelaic acid serum enriched with other actives
   I use a lot of retinoids and direct acids in my skincare routine, trying to get rid of several darker spots on my skin from unprotected sun exposure in the past. Azelaic acid is believed to have multiple benefits for skin, in particular supporting mild exfoliation and skin turnover. I have the 10% azelaic acid suspension from ordinary, but I dislike its texture heavy-loaded by silicones. So, I wanted to try azelaic acid in another forms like cream or serum.TOSOWOONG Azelaic Acid 10% Face Serum is a high-quality Korean serum that features not only 10% azelaic acid, but also squalane, multiple types of hyaluronic acid, niacinamide, several plant extracts including centella asiatica, panthenol, ceramide NP, zinc. Such ingredient combination sounds very promising to me, as most of them are typically used together to support the skin barrier, thus helping to seal hydration in the skin. It is a near-transparent oily liquid, with a light floral scent. It comes in a 33 ml plastic bottle with a glass dropper. It absorbs rather good, however I feel some tackiness in the finish. Anyway, I never leave serums unsealed, I cover it with moisturizer and sunscreen. I did not notice any increased oiliness. I will continue to use it, as skin turnover and visible effects typically appear with weeks-months’ timeline.It is not recommended to use azelaic acid products at the same application time with retinoids, peptides, vitamin C, direct acids, it’s better to separate them between day/night applications.

    I have rosacea and use this. It had reduced my redness and bumps. I don’t get bumps often but it does get rid of them overnight when I do. It doesn’t sting or cause irritation for me (I have sensitive skin). It also doesn’t contain aloe or shea (both cause a lot of irritation on my skin. I recommend!

    敏感肌や混合肌でも刺激を感じにくいのが安心ポイントです。テクスチャーは軽めで、肌になじませるとべたつかず、日中のメイク前でも使いやすいところが気に入りました。使い続けるうちに、毛穴の目立ちや肌のざらつきが少しずつ改善され、肌全体のトーンも明るく見える印象です。油分と水分のバランスを整えてくれるので、乾燥やテカリが気になる季節でも活躍します。独特の香りが少し気になる人もいるかもしれません。

    I have used Tosowoong products for about 6 months and it really suits my skin and works well.The products are gentle on my skin, absorbs well and make my skin smoother and softer. Great to apply make up afterwards.The price is also affordable.I also like the dropper to take the serum out, not messy. It’s a great product.
