When first time using, it seams as if it is sticky but once you get past that, it becomes smooth. A little goes a long way and when using the directed amount, it doesn’t seem sticky at all.

I ordered the serum and Snail Musin 92% face moisturizer and use it in the morning and I use the serum with my other retinol night cream (not COSRX) in the evening. After using this product for over 6 months I saw great results. Fine lines are reduced significantly, skin pores get smaller and the whiteheads disappear! My facial skin is glowing looks healthy and feels smooth. I'm ordering my 2nd bottle of the serum and will need to order the moisturizer probably next month. I just ordered a bundle of the serum with the Vitamin C serum. Normally I have to order facial serum and moisturizer between 3-4 months. But this product I use it for over 6 months. It's because they're so light and easy to absorb on the skin and have no scents or perfumes. For the price they're reasonable. I'm thinking of buying the facial wash soap but I love my Cetaphil Hydration face wash and toner and religiously use them because it didn't make my skin dry after washing. I hope this review helps ladies who are in the same phase as me and have similar skin conditions. Always order the product from their store, not another seller (normally selling at a cheaper price) because lots of fake products, read each product's characteristics so you can order the one that is right for your skin. Happy shopping! 🤗

So much about this serum turned me off. 

It is a very thick oil-based serum. It goes on heavy and yet drips down your face very quickly and not staying where I want it to. 
It made me break out in places on my skin that I don’t normally have acne and it was painful. 
To top it off, it did nothing for me. I’ve tried other retinol products and even the worst was able to give my lines a little amount of plump but this one did nothing. 

I have an oily T-zone and I really prefer to not use anything that is oil based as it causes me break outs when I don’t even break out to begin with. 
That being said, I am not a fan of this retinol serum. It is completely oil based and very thick. I made myself try it since I had spent money on it and also because the reviews made it seem so good. 
Personally, it wasn’t good for me at all.

I  have a hard time trusting whether or not a product works because I've tried many. However, ever since I got this, I've found that nothing that I've tried in the past works as well as this has! It's truly a game-changer and I couldn't be more grateful because I'm very sensitive about how my face looks.

Nothing for me was BAD about this product.

I am loving this new Clinical Solutions line from Mary Kay. I am already experiencing fine lines and dare I say WRINKLES!! They are prominent in my family and no matter how much attention and hydration I’ve given my skin, it’s undeniable.
That being said, I’ve tried lots of brands, treatments, and techniques using retinol and I assure you they are NOT made equally.
This one is giving the most, for me. It’s a very simple textured-cream based retinol that applies well. It goes on very evenly and easily. It absorbs into my skin immediately and I get results within moments. The plumping effect is very apparent in this retinol which allows my lines/wrinkles to become firm quickly. I’ve been using it for about a month and the lasting results are there. 
The price point seems reasonable as it definitely is giving me the results I like.

I’ve used other microdermabrasion sets that offered higher quality results.

It has being Three Months since i've been used the Microdermabrasion set, i have not seen big change. However, it's good for dry Skin. It fade little bit my scares acne, but this is not the way i was told it worked. I was expecting from this product openes the pores, but it does not go into the skin. it does not go deep. So far i'm in my second set, but my deep scar acne still on my face. The product so small I do not know how many I will need to get way of my scar acne. Besides, my acnes still pop up. However, do not give-up because it is very good for dry/sensitive skin. No matter how dry and sensitive your skin is, it helps. This product need a good bleaching bar soap along with it to help get way of the scar acne faster. As i said, do not give it up because it is a good help for people who have very sensitive and Dry skin like me, this is keep me still using it. For the dry and sensitive skin, you'll see the change right away, but for the acne scars, you won't see in two weeks as the producers said. I'm going to my third set twice a day, my light acne scars are starting to fade up. I meant for the deep scars, i have not seen big change. It workd very slow.
