Not for me

I received a sample when I bought some body butter last fall. I found the sample hard to gauge it's effectiveness because it was a super small amount, but was intrigued from the positive reviews that I went and back later and bought a bottle.
The liquid is fine and oily and you only need a couple of small drops to cover your face or target area. I found it has a super mild, if any scent to it and found it to be gentle, I did not suffer from any breakouts while using it.
My skin absorbed it really well and it did not leave an oily feel after applied, my skin felt smooth. After continued use my skin felt refreshed and hydrated, I had some dry skin on and around my nose and this oil moisturized it and within a couple of days it was gone. For me, I didn't get the wow factor, I didn't notice any visible signs while using the entire bottle over the course of a couple of months besides my skin being soft, smooth and moisturized. I don't think any 'new' fine lines appeared on my face which is good, but also, the few that I do have around my eyes and close to my mouth were still there and didn't appear to become any fainter or lessen. I most likely won't buy this again, it didn't do anything amazing for my skin that I don't already get from other products I currently use.

It's okay?

I've used two bottles of DOY last year and it was just okay. It didn't do any harm on my skin but I didn't see the amazing results other users have been experiencing. It is a shame because the price point and availability is accessible. I think the only benefit I got from this serum is how my face is smoother from the serum but it didn't have any other benefits. I will have to pass on this serum.
