Seeking better options now

Although allegedly formulated for a year of shelf stability, within a few months this oxidized to a very dark brown-orange. Even if the formula is still active, contradictory to most information out there, I can't use it during the day because of the cast it puts on my skin. Formula has always smelled like hot dog water, too. I want to believe this works but I just don't know if I'm getting what I paid for, and using it is too inconvenient and unpleasant to justify the proce.

Not worth the price

Overpriced and it came pretty oxidized already. I missed my window of returning since I was trying to figure out if it was normal.

Can’t Live Without It!

I’ve used this product for the last 2 years. It’s my can’t live without serum. It does leave your skin orange but I use it at night time and the sticky feeling goes away as your skin absorbs it. It’s really good. I highly recommend. It’s the one product that I’ve stuck with.

Product turns my face orange. Happened right after I bought it. For this price point, that shouldn’t happen. Would not recommend.

An essential product

I will not go without this serum. I love it, get compliments on my skin often, I don’t have any texture, my fine lines are basically gone and my face is so bright and clear. I will repurchase for life

Turns skin orange, do not buy

Dr. Dennis changed their formula for the FAR worse. It stains my skin orange, and can be clearly seen even after trying to rub it in. Don't even get me started on what happens when I sweat, orange droplets fall down my face! It smells and it's sticky and it's far too expensive for what they've done to it. Furthermore, I tried to return the product to Sephora and they would not take it back.

Stay Away

Never again- stains everything! I wanted to love this as I love DDG skincare but leaving orange pigments on my clothes is not ok. Not to mention the smell. Sorry but for the price you have better options. Dr Gross needs to do better

Not for me

Texture is nice but definitely not a good vitamin c. Or leaves orange marks everywhere and doesn’t do much.
