Reviews Summary
Customers say this serum has a lightweight, easily absorbed texture. Many reviews mention starting slowly with twice-weekly applications before building up frequency. Common feedback includes noticeable improvements in skin texture and appearance after several weeks of use. While most users report smoother, plumper-looking skin, some note the product's distinct scent. Reviews frequently highlight its gentle nature, though a few experienced dryness and suggest pairing with moisturizer. The runny consistency receives mixed comments, with some finding it convenient while others prefer different packaging.

    Feeling plump

    It’s smells a funky but I think most retinols do. Put in on in the evening and my face still feels plump and hydrated in the morning. Not sure what fine lines and wrinkles have been reduced but I’ve only been using it a month.

    Soothing

    I read all the recommendations to use it and stared slowly. I must admit I was scared at first, but I shouldn’t have worried.

    I have built up to using it once every 3 days and my skin looks radiant and the fine lines seem to be smoothed away. Happy
