¡Un cambio total para mi piel!
Llevo usando este producto durante unas 4 semanas y los resultados han sido impresionantes. Mi piel está mucho más suave, hidratada y con un brillo natural que antes no tenÃa. TenÃa algunas zonas con resequedad y rojeces, y han mejorado notablemente. La textura es ligera, se absorbe rápido y no deja sensación grasosa. Además, el aroma es suave y muy agradable. Lo uso a diario y se ha convertido en un paso esencial de mi rutina de cuidado facial. ¡Súper recomendado para quienes buscan un producto eficaz y delicado con la piel!

Great for minimizing pores
Love this serum! I’m not the best with skin care routines, but they say it takes 2 weeks with most serums to notice a difference, but this one is WORTH IT! It helps shrink my pores and reduces oil. I notice when I miss spots in my hair line or corner of my jaw because then a small pimple may begin to form and I quickly begin covering those spots. It doesn’t dry out your skin nor feel sticky after application.

Helps with hormonal acne
Iâve had hormonal acne my entire life and always had trouble getting rid of it. Using this product consistently I can definitely see the difference. Brightens up my skin and helps reduce my poors. I have oily skin and would recommend using this.

El original es excelente
Este producto con el uso constante muestra buenos resultados. Sugiero estar pendiente de comprar el original ya que hay falsificaciones chinas más económicas que usan los mismos empaques

âï¸ð¨ TOO STRONG FOR 1st TIME USERS ð¨âï¸
While searching for products to help fade melasma, I decided to get something with niacinamide instead of vitamin C because of its instability. However, I really wish I would have done a little more research.. After using this for almost a month, I found out that the percentage is much too high for first-time users and/or those with sensitive skin. I might have been fine if I would have slowly introduced it into my routine by using the tiniest amount once or twice a week, but I had no idea that we have to build up a tolerance to new treatment products before we can use them daily.So, my skin is very oily, extremely sensitive, with enlarged pores and melasma. Right off the bat I started using a dropper full of this day and night. ð¤¦ð»ââï¸ BIG mistake. Not only was my face cherry red all day long, but it dried out my skin in certain areas, AND because I did not bring it close to my eyes or lips, there were noticeably brighter rings around them. It looked like I had a shade of concealer around my eyes and lips that was 5x lighter than my skin tone. A little over a week ago I quit using it entirely, thank goodness I did. Within a couple of days the dry areas and red irritation disappeared, while the bright rings finally returned to my normal skin tone. I regret not taking a picture when it was obvious enough for others to see, you will just have to take my word for it. ðAnother reason 15% is too strongâmaybe unless you are an EXPEIRENCED userâis that many other products we use already have a small percentage of niacinamide added into their serums/moisturizers. For example, CeraVe has it in almost all of their moisturizers and sunscreens. So layering that on top off 15%, could possibly be giving your skin an overdose of up to 16-20% or more. âï¸ð¨âï¸ At those concentrations it could be very harsh and do the exact opposite of its intended treatment.That being said, if you already have a tolerance to niacinamide and are using other serums/moisturizers that lack it, I would definitely give this a try. ð Otherwise, I strongly suggest starting with 5% and working your way up to 10%. Also, be aware of the niacinamide content in other products you use with this!Finally, as for the product itself, because I used it wrong, I don’t have much to truly review other than I did notice it helped with excess sebum control. For me, that only benefit was not worth the side effects I encountered. ð ð»ââï¸Also, I noticed a few reviews mention you have to âshakeâ this before you using it. While that is true, I would not actually shake it as if I am trying to mix a protein drink. Instead, open it and squeeze the dropper to empty it. Close it back up WITHOUT squeezing it again, you want the dropper to be sans product while you do this. Roll it back and forth a few times between your palms like you would a nail polish, turn it around and roll it again. Thatâs all you have to do.In concluson, because I do love COSRX products, for the extra sebum it got rid of, and the hope that this serum will do its thing when I work up a proper tolerance to it, I rate it 3 stars. They lose two because it is too strong and because they could easily warn consumers how to work up a tolerance for daily use, yet neglect to. ðI hope this helps.
