Great stuff definitely recommend at least trying
I've been using the TruSkin Vitamin C serum for over a year, and it's done a solid job brightening my complexion and fading dark spots. Finally gave the full Face Serum Trio a shot with the hyaluronic acid and retinol, and after about a month, it's working great, just like the Vitamin C. The hyaluronic acid hydrates my skin well without any grease, and the retinol's knocked down some fine lines, making things smoother and fresher. Layering them has improved the texture and glow noticeably. No irritation on my sensitive skin. Solid value—I picked this up at $26 when it was Prime Day, but even at that $40 price range, it's still worth it in my opinion since it can last a while. Definitely recommend

Great deal, my face loves them
Love these and got them on a great deal! The retinol and vitamin c my face loves!! The hylalonic acid seems super similar to the vitamin c in formula, I use that one less.

My Skin Looks Brighter and More Hydrated
I use the vitamin C and hyaluronic acid in the morning after I wash my face, and then I use the retinol at night followed by my moisturizer. This routine has made a noticeable difference in my skin.
I especially see it under my eyes and with my crow’s feet. My skin looks more hydrated, brighter, and overall healthier. On days I forget to bring the serums with me when I travel, I can actually tell. My skin feels more dehydrated and just looks more dull.
When I’m consistent, my face looks more plump, glowy, and hydrated. That alone tells me these are working.
They are also very lightweight and not greasy or oily at all. They absorb quickly into the skin and do not have a strong smell, which I really appreciate.

Would highly recommend
I was looking for something new and not crazy expensive. I have been using for 3 weeks now and I seeing good results. My skin is looking hydrated and feels awesome. I did also purchase the brightening moisturizer in addition to the serums as well as a night cream for my evening routine. Will continue to purchase. I do see that the droppers can stick but nothing that prevents you from using the product. There is very little scent which is a plus for my liking.
