Quality products that really work
Very happy with The Ordinary products. My skin is glowing, smooth and my pores are smaller. They are easy to use and a little goes a long way. This is a great starter pack if you are wanting to try the line.

No unsafe ingredients
I always love this brand. Their products are amazing quality for skin improvement. As an esthetician student learning about the dangers of certain ingredients, with this brand I don't have to worry about that.

Promise made. Promise kept.
Excellent! I could see a significant difference in days and the results are now awesome: even skin, fewer wrinkles (not that I had many, but that was a pleasant surprise 😄) and a slight glow (not sure why). Three drops of the hyaluronic, three or the niacinamide and two of the caffeine (one per eye) and you're done. Recommendation: follow the suggested order for layering them. I do caffeine, niacinamide then hyaluronic.
Bonus: They go one smoothly and are light. I used to use mostly L'Oréal, but this stuff is much lighter and smoother.
Best bonus of all: a friend noticed the improvement in my skin and he switched as well. Trust me: there's nothing ordinary about The Ordinary.

Staple in my skin care
I buy these over and over. I used to get these from ULTA- however, having them shipped to my door is not only more convenient but also saves me money from wandering around ULTA LOL. Initially, I loved how light weight these serums are. The application was easy and smooth. My skin felt so hydrated after all three AND i noticed my face evening out in color! I am almost out of these three- and about to order them again.
