    Great Serum

    I like this serum a lot, the texture is reminiscent of like makeup primer which feels nice. HOWEVER, it does cause some pilling depending on the other products used with it. I have this niacinamide emulsion I like to use and when put over this serum it definitly pills and I cant put makeup over it. That said, if you make sure the products you use with it dont cause this its an AWESOME hydrating serum.

    So very helpful!

    I bought the product but I couldn't incorporate it in my routine because I didn't want to disturb the balance I struggled to achieve. Then I started using it to "dilute" heavier foundations that I have but are proving too heavy for my post menopausal skin, excellent solution! I also use it everyday when I wash my face before I go to the gym and I want some hydration, but not a proper skin care routine. In general, I find it a very useful product and will buy it again.

    It hurts my face, fine on my body

    My skin is labeled as generally very dehyrdated ànd dry, due to a medical condition, so I am always looking for better or more hydrating serums to keep my skin from feeling tight, itchy, rough and flaky. Hence, I was very excited to try this product!

    I honestly do not think though my skin can be labeled as sensitive skin: although my skin is prone to turn red quite easily, products rarely hurt or sting.

    Something turning my face beet root red isn't really a concern for me; it usually passes in 5'.

    This serum however, hurt so bad unfortunately, and gave me lasting irritation & redness...

    It gave me the impression of rubbing alcohol on my face...

    I tried it in (cold, wet) winter as well as (warm, dry) summer; this did not change anything for my experience unfortunately.

    Not wanting to cause unnecessary waste, I have continued using/finished up the product in winter time by layering it under my body lotion for extra hydration; which did not cause any discomfort!
