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.

Best Skincare Set — My Second Time Buying & Still Obsessed!
This is truly the best skincare set I’ve ever used! This is my second time purchasing it, and I’ll definitely continue using it. My skin feels smoother, more hydrated, and just healthier overall every time I use these products. The formulas are gentle yet effective, and everything works so well together as a routine.
I love that the set is high‑quality, consistent, and gives visible results. It’s become a staple in my skincare lineup, and I honestly don’t want to be without it now.
Highly recommend — especially if you’re looking for a reliable set that actually delivers!

Nothing ordinary about it…
I bought this for my 14 year old niece for Christmas and it was a big hit. Apparently The Ordinary is on all of my nieces’ Amazon wish lists, and I have no shortage of nieces. I see it pop up every time I check their lists for birthdays, Christmas, graduations, and every other buying holiday in between. When you’re a teenager, having clear, fresh looking skin is basically a top priority, and she was really excited to start using these. She’s been experimenting with different skincare lately, and so far this is the only brand that hasn’t caused her to break out, which is a pretty big win at 14. She said it feels light on the skin and leaves her face feeling clean and hydrated without being heavy or sticky.
And honestly, there’s nothing ordinary about this stuff except the name. It’s a great little starter set for someone getting into skincare, and judging by the reaction I got when she opened it, it also earned me favorite aunt status, which I’ll gladly take.
