# Real Barrier Retiniol Pore Tightening Serum 30ml Retiniol Pore Tightening Serum 30ml is Real Barrier's Korean-market serum, sourced for the US market rather than reformulated for it. - Brand: Real Barrier - Product: Retiniol Pore Tightening Serum 30ml - Price: $47.50 - Availability: In stock - Size: 30 ml - Market: Korean market, the version sold in Korea - Made in: Republic of Korea - EAN (barcode): 8809911695112 - Category: Serums & Ampoules ## Key benefits - Ten forms of hyaluronic acid on one panel, not a single token inclusion - Niacinamide on the same panel, the formula's active - Collagen Extract on the same panel, the formula's protein - 30 ml to a unit - Korean GS1 barcode matched against a Korea sourcing supplier's record for this item ## How it works The panel on this serum names ten forms of hyaluronic acid rather than one: Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, Hyaluronic Acid, Dimethylsilanol Hyaluronate, Hydrolyzed Sodium Hyaluronate, Potassium Hyaluronate, Hydroxypropyltrimonium Hyaluronate, Sodium Hyaluronate Crosspolymer, Sodium Hyaluronate Dimethylsilanol, Sodium Acetylated Hyaluronate. Sodium Hyaluronate is the salt of hyaluronic acid, and it is what most products labelled hyaluronic actually contain. The salt dissolves more readily and the molecule is smaller, so it sits in the outer layer of skin rather than only on top of it. On this panel it sits alongside Niacinamide, Collagen Extract and Tocopheryl Acetate. Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is used at roughly 2 to 5 percent for the look of uneven tone and visible pores, and it is water soluble, stable and comfortable beside almost every other active, which is why it turns up in so many lists. ## How to use 1. Use Real Barrier Retiniol Pore Tightening Serum 30ml after toner and before cream, patting rather than rubbing it into skin. ## Ingredients Water, Dipropylene Glycol, Glycerin, Betaine, Glycereth-26, Propanediol, 1,2-Hexanediol, Niacinamide, Methylpropanediol, Macadamia Ternifolia Seed Oil, Xylitylglucoside, Butyrospermum Parkii (shea) Butter, Xylitol, Sodium Hyaluronate, Chitosan, Carthamus Tinctorius (safflower) Seed Oil, Salvia Hispanica Seed Oil, Hydrolyzed Hyaluronic Acid, Hyaluronic Acid, Collagen Extract, Pentylene Glycol, Polyglycerin-3, Tocopheryl Acetate, Panthenol, Methyl Methacrylate Crosspolymer, Glyceryl Polymethacrylate, Hydrogenated Lecithin, C12-14 Alketh-12, Squalane, Hydrogenated Polydecene, Caprylic/Capric Triglyceride, Anhydroxylitol, Acrylates/C10-30 Alkyl Acrylate Crosspolymer, Sodium Polyacryloyldimethyl Taurate, Polyglyceryl-3 Methylglucose Distearate, Butylene Glycol, Retinol, Allantoin, Bakuchiol, Sodium Stearoyl Glutamate, Tromethamine, Diethylhexyl Syringylidenemalonate, Sodium Polyacrylate, Brassica Campestris (rapeseed) Sterols, Ethylhexylglycerin, Dipotassium Glycyrrhizate, Adenosine, Cholesterol, Polyglyceryl-10 Laurate, Sodium Phytate, Phytosteryl/Behenyl/Octyldodecyl Lauroyl Glutamate, Aluminum/Magnesium Hydroxide Stearate, Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate, Potassium Cetyl Phosphate, Tris(tetramethylhydroxypiperidinol) Citrate, Bis-Capryloyloxypalmitamido Isopropanol, Dihydroxyisopropyl Palmoylpalmamide, Myristoyl/Palmitoyl Oxostearamide/Arachamide MEA, Tocopherol, Ceramide Np, Phytosterols, Linoleic Acid, Linolenic Acid, Polyglyceryl-10 Oleate, Sucrose Palmitate, Dimethylsilanol Hyaluronate, Hydrolyzed Sodium Hyaluronate, Hydrolyzed Elastin, Potassium Hyaluronate, Hydroxypropyltrimonium Hyaluronate, Sodium Hyaluronate Crosspolymer, Sodium Hyaluronate Dimethylsilanol, Sodium Acetylated Hyaluronate, Xanthan Gum ## FAQ ### Where does Real Barrier Retiniol Pore Tightening Serum 30ml go in my routine? Apply it after cleansing and toning and before moisturizer, since a serum's concentrated formula works best on freshly prepped skin rather than layered over a heavy cream. A few drops are usually enough for the whole face; pat rather than rub it in. Follow with moisturizer to seal in what the serum just delivered. ### Can I use Real Barrier Retiniol Pore Tightening Serum 30ml with other actives, like a retinoid or another exfoliating acid? It generally layers fine with most other actives, but introduce anything new gradually rather than adding several new steps to a routine at once. If you are already using a strong exfoliating acid or a prescription retinoid or a strong acid exfoliant, alternate nights rather than stacking everything at once until you know how skin responds. When in doubt, patch test the combination on a small area first. ### How many drops of Real Barrier Retiniol Pore Tightening Serum 30ml should I use? Two to three drops or a single pump is enough for the whole face for most people; more product does not mean faster results, just more runoff. Pat it into skin in sections rather than dragging it across the face. Extra can go onto the neck and décolletage if there is enough left over. ### Is Real Barrier Retiniol Pore Tightening Serum 30ml suitable for daily use? Yes, this is formulated for regular AM and/or PM use as a standard routine step rather than an occasional treatment. New users can start once daily and build up to twice if skin tolerates it well. Consistency over weeks, not a single application, is what a serum like this is built to reward. ### Is Real Barrier Retiniol Pore Tightening Serum 30ml the authentic Korean-market formula? Yes, this is the same serum Real Barrier sells through Korean retail, sourced specifically for Korean Pharmacy's US catalog rather than reformulated for a US shelf. It carries its original Korean-market batch coding intact. That is the version this brand's reputation is actually built on. --- Page: https://korean-pharmacy.com/products/real-barrier-retiniol-pore-tightening-serum-30ml
