    Love it

    The serum is a great consistency, and has not hurt my skin at all. Love it!

    Needs to be packaged differently

    This serum is very runny and it is really challenging to use because of that! All the product images show it as a lotion-like consistency but it comes our completely liquid. Every time I twist off the lid, the inside is coated in the serum and it is difficult to keep it from dripping out. After I've squeezed some out onto my hand I then have to try to get the cap back on the squeeze bottle before it leaks out on the counter, or balance it against the side of the sink to keep the hole facing up (if u held the uncapped bottle out horizontally or with the hole facing downward it would all stream out). Because retinol tends to be a lurid yellow, it will leave a noticeable mark on your sink when it drips that you will then have to wash off.

    As for the efficacy, as far as I can tell this is a good retinol. I have not had an adverse effects or retibization flaking. This could be because I spaced out my usage well and gradually increased the frequency, but I think this is also just a gentle product. I can use this daily without irritation.

    I think it would be perfect if it was thicker or in a serum bottle with a dropper!

    an anti-aging must

    Slowly and steadily have been improving my hyperpigmentation and fine lines. Tends to sting initially, but resolves a quickly as it comes on. Need to pair with a daily SPF.
