I saw a beauty guru's youtube video about her skin care, and she raved about using vitamin c to boost the effectiveness of all skin care products she uses. She explained that, when you apply vitamin c on the face, before applying you skin care routine, the products will be absorbed in a so much more effective way. Besides, vitamin c is excellent to boost skin vitality and natural luminosity and elasticity. She stated that the results come not in a short period of time, but it is so worth it. I was very excited when I searched for vitamin c at Jolse and ordered it at once. I already incorporated it in my night skincare routine and I am looking forward to see the results!
