    Great product for the sensitive skin

    Lightweight texture and no scent makes it a perfect choice for the sensitive skin

    Would recommend

    I have been using this serum for a month now, my skin feels much more hydrated and my pores have visibly become smaller. I introduced this step and left the rest of my routine the same so I am pretty sure the improvements come from the serum. Another thing I noticed is that I wake up with a less greasy T-zone.

    Ok

    The serum is ok but it’s really really liquid. I was expecting more of a serum/cream consistency type of thing

    Real Results

    This is one of my favorites. Part of my day and night routines. My skin is smoother, firmer, brighter, more hydrated. Absorbs immediately and prepares my skin for my other products. This one is a 10 out of 10!

    Great serum

    I am writing this review after finishing bottles of this serum and ordering it again and again. I apply it as the first step in my skincare after cleaning & toner. With hyaluronic acid in its formula, I feel like my skin absorbs the subsequent serums and creams better after using this serum as the first step. It absorbs very quickly without any residue or sticky feeling. I sometimes apply it multiple layers, but even then it never leaves a residue or weird feeling. I am very happy with this product.

    Very hydrating

    I got this as a sort of skin barrier support as my skin has been suffering from the insane change of temperature the last month. I use it between my toner and hyaluronic acid serum and I do have the feeling it adds a layer of hydration and plumpness. Would definitely repurchase.

    LOVE

    i got it for free once, and its the best and my favourite serum ive ever used. i have honestly no idea what it is and what it is used for, but i do know it made my skin smooth and texture free quickly. i didnt use anything else besides oil and water based cleansers and a moisturiser.

    Great product

    Really calming to my skin. It’s been noticeably different since using this as one of a few new products on my skin. Will continue to use it. Consistency surprised me as was expecting it to be creamier.

    You can use instead of toner also since it's very light and watery
