Suits my skin well, but caution on the Alcohol Denat

Brightening Vitamin Serum with Powerful IngredientsThis is very much based on first impressions, as I haven't been using it long enough to see visible long-term results. However, so far it has been very gentle even on my mature, sensitive skin. I've used several products from Centellian 24 and my skin has always responded well. It's become one of my favorite brands. I'm not new to Vitamin C or Niacinamide, so my skin is somewhat tolerant of these ingredients.The serum has a thin texture and absorbs quickly into the skin, which is nice as many Vitamin C serums leave a tackiness behind that can be tricky to layer with. However, one of the reasons it absorbs quickly like it does is because it includes Alcohol Denat, which is not usually a favorable ingredient. It can be drying or irritate sensitive skin. I haven't really experienced this with this product, but it's something to be aware of. There's no added Fragrance, and the product doesn't have any noticeable scent that I can detect which is unusual for Vitamin C serums.The ingredient list includes 15% Vitamin C, Niacinamide, and TECA (a Centella derivative). I’m interpreting the 15% reference as the combination of those key ingredients, not just the Vitamin C itself, but it’s a little unclear. Based on some quick analysis, most of the ingredients are safe and good for your skin aside from the Alcohol Denat. I love that the formula is packed with brightening and skin-loving ingredients. As with any new skincare product, I always recommend doing a patch test first, especially if you have sensitive skin like mine.I haven't experienced any irritation, redness, or sensitivity reactions. My skin feels hydrated and looks a bit more radiant after application. I'm looking forward to seeing the long-term results as I continue using this serum, particularly for evening out my skin tone and addressing post-acne marks.While I would always prefer a pump over a dropper, the dropper works well and makes it easy to control how much product you use. A little goes a long way, so the 30ml bottle should last a while. The instructions for this product say to use this twice a day, but I’m only using it once a day in the morning. I have other treatment serums I use a night.Overall, based on the ingredient quality and how gently it's treating my skin so far, I'm impressed. This is 5 stars for being a well-formulated serum with powerful ingredients at a reasonable price. I'd recommend it for anyone looking to address uneven tone and dark spots, though be aware of the Alcohol Denat if you have particularly sensitive or dry skin.Received in Mar 2026, expires in July 2028, no shelf life indicator, made in Korea.Ingredients (text extracted from a photo):Water/Aqua, Niacinamide, Butylane Glycol, 3-O-Ethyl Ascorbic Acid, Alcohol Denat Pentylene Glycol, Ascorbyl Glucoside, Glycereth-26 Propanediol, Glycerin, Methylpropanediol, Caprylic/Capric Triglyceride, Isononyl Isononanoate, Trome thamine, Carbomer, Polyglyceryl-10 Laurate, Succino-glycan, 1,2-Hexanediol, Cyamopsis Tetragonoluba (Guar) Gum, Panthenol, Dipropylene Glycol, Castor Oil/IPDI Copolymer, Ethylhexylglycerin, Allantoin, Gluco-sylrutin, Sodium Hyaluronate, Adenosine, Disodium EDTA, Daucus Carota Sativa (Carrot) Root Extract, Canola Oil, Madecassic Acid, Asiaticoside, Arginine, Beta-Glucan, Asiatic Acid, Daucus Carota Sativa (Carrot) Seed Of Amodimethicone, Hydrogenated Lecithin, Heilanthus Annuus (Sunflower) Seed Oil, Tocopheryl Acetate, Beta-Carotene, Tocopherol, Ectoin, Pyridoxine HC), Salicylic Acid, Gluconolactone, Dipotassium Glycyrrhizate, Ceramide NP, Glutathione, Hydroxypropyltrimonium Hyaluronate, Candida Bombicola/Glucose/Methyl Rapeseedate Ferment Hydrolyzed Hyaluronic Acid, Sodium Acetylated Hyaluronate, Hyaluronic Acid, Sodium Hyaluronate Crosspolymer, Hydrolyzed Sodium Hyaluronate, Potassium Hyaluronate, Ascorbic Acid, TotarolVer más

15% vit c derivatives, alcohol + acids, there's a lot going on

This vit c serum combines multiple vitamin C derivatives (3-O-ethyl ascorbic acid and ascorbyl glucoside) with niacinamide for targetting dullness and uneven skin tone. 15% vit c sounds high, but it's comprised of derivatives, which are more stable, but also not as potent as pure ascorbic acid.The potentially irritating factor of the vit c is balanced by soothing and hydrating ingredients such as panthenol, centella derivatives, beta-glucan, and ectoin. There is also no fragrance added which is awesome.The serum itself is not tacky and absorbs well. It does impart a temporary cosmetic glow but I'm not sure the vit c derivatives are efficient enough to have long term impact, but your mileage may vary!!However, I did notice that alcohol is high in the ingredient list (probably why it absorbs and dries quickly) plus the inclusion of additional actives like salicylic acid and PHA—really is potentially not a great combo for reactive skin or folks with already compromised barriers. That is a lot going on.All in all, this is a nice and lightweight serum that feels good on the skin. If you're new to vit c you could try this to get started, but I prefer a more targeted formulation without the extra frills.Ver más

Glowy vitamin C serum that layers really well under makeup

I’ve been using this serum mostly in the morning, and I think the formula is actually much more interesting than a typical “cute glow serum.” It feels like a more active Korean-style multi-correcting vitamin C product rather than a super basic hydrating serum.The texture is lightweight and absorbs quickly, although on my skin it stays slightly tacky for a few minutes. I personally always follow it with a moisturizer and SPF anyway, so that doesn’t bother me. Under makeup it works really nicely — foundation applies evenly on top and I haven’t noticed any dryness or patchiness during the day.My skin also feels a bit more “dense” and smoother when I use it consistently, if that makes sense. Not in a heavy way — more like the skin looks healthier, more hydrated, and slightly more firm.I also appreciate that despite having a strong active ingredient list, it doesn’t feel aggressively harsh on my skin. There’s vitamin C, niacinamide, centella components, panthenol, and a lot of barrier-supporting ingredients, so it feels more balanced than some very intense vitamin C serums that just irritate the skin.That said, I do think sensitive or damaged skin types should patch test first because the formula contains a lot of active ingredients and alcohol quite high in the ingredient list. But for combination skin like mine, especially if you want glow, smoother texture, and something that works well under SPF and makeup, I think this is a really solid everyday vitamin C serum.Ver más

Lightened My Dark Areas Under the Eyes in 4 Weeks. Amazing!

The Centellian 24 Madeca Vitamin Serum is a triple complex TECA clear hyaluronic acid serum. It's unique ingredients proprietary in nature address darkening of the skin that includes blemishes and freckles. I use this highly specialized Korean serum for my racoon eyes (darkened areas beneath the eyes) for I work long hours at the office and way into the evenings burning the midnight oil. The result is darkening of the soft skin under your eyes. Usually the solution to this is to increase the amount of your sleep and proper hydration. I use this product daily gently applying a very small amount of serum, usually two drops, one on each side, gently massaging it in to the surface of the skin. It is absorbed by the skin within minutes. I've been using this product now for two months. The first month was daily for 30 days, and then a few times per week thereafter. Visible results were noticeable after the 4th week. Almost all of the darkened areas have lightened up much to my surprise, not that I was not a believer of this product, but because I have tried so many others with poor results. I now apply this product twice a week to maintain healthy skin. I am very content with its performance and quality. I am happy with this brand. It is value priced. Recommend.Ver más
