I take the bus to work everyday so by the end of day my face is filled with dust and dirt. I use cleanser every morning and night but it doesn't seem to wash away all the dirt and debris completely. My friend recommended the C20 Serum and I been using it for 2 weeks now. After the 1st day of using, I can already the difference when washing my face. There were less dirt and dust on my face. This is a premium skin care.


Great Serum! My dermatologist recommended this to me for uneven skin tone and my skin is so much more radiant and bright.


I saw an ad about how vitamin c serums are not created equal. After watching the video, I came to realization that the vitamin c serum I got for 19.99 is not comparable to what Dermaesthetics has. I've been using this serum for about 2 weeks now and my skin is GLOWWWING. I used the cheapy stuff for over a year without results.


I wear a hat everyday at work. If you know anything about wearing a hat in the sun every single day, your forehead becomes whiter than the rest of your face. I did some researching online and found an article about L-Ascorbic acid and how it help with discoloration. I was overwhelmed with the amount of products online so I reached out to a friend of mine who was a license skin care technician and she told me about Dermaesthetics. She did advised that they are a little more expensive then others, but if you want results, then you have try it out. I placed my order in and the product arrive 2 days later! So Fast! I've been using the product for 3 weeks now and I can see a VISIBLE change in my skin. Miracle product. They run out of stock alot on this product so I bought 4 at a time to stock up :)


I have some discoloration on my left cheek. I tried a few different products online and none of them helped. I saw an ad on facebook comparing two vitamin c serums from different vendors and I was amazed. I caved and bought a serum to try. After a few days, my skin feels so much brighter and radiant. Will definitely buy again once I run out!
