I tried few Hyaluronic acid serum from different brands and honestly I didn't like it. It either gave me breakouts or pilled on my skin and didn't feel right on my skin at all so I gave up on that and switched to Beta Glucan as I heard it's better than Hyaluronic acid at hydrating the skin. I used Iunik Beta glucan serum and though it was better than Hyaluronic acid as it didn't pill on my skin, I didn't like the consistency of the product felt too sticky, thick and slimy and didn't really feel it sinked into the skin very well but still I wanted a good Beta Glucan serum that has clean and short ingredients list I looked for other brands and finally settled for this. Lol the price did scare me as it's pretty expensive (the most expensive serum I have ever bought) and it has short expire date as u need to finish using this within 6 months after opening it. But it was worth it for me because this has a clear, thin, slightly viscous serum that spreads easily over the face and absorbs very quickly too. It leaves zero tackiness or stickiness, doesn’t have a scent and doesn't pill, goes well with any products too. It's hydrating too. The good thing about this product is that it's Paraben-Free, Sulfate-Free, Alcohol-Free, Silicone-Free, Fungal Acne (Malassezia) Safe and has Minimal Ingredients. IMO this serum is safe for all skin type! Hope that JKosmmune would never change the ingredients list or discontinue this product cuz this is one of the best serum in the market!
