    Soothing Chill for the face

    I actually have a sore developing now and then when i drink coffee, which is a symptom of dehydration which caused the corner of my lips skins and above it to have painful skin torns. I applied the serum and used Skin Soothing Cryo Massager on it and it reduced to a very tiny red patch from the big size in just a few minutes of 1 application.
    Thank you for this product Est-lab and the forever customer orientated team

    Cannot recommend this enough

    Believe me when I tell you this serum is one of the best serums I’ve tried. It has calmed my eczema skin so much. I like to use it with the anti-stress moisturiser and i wake up to the nicest looking skin. Cannot recommend this enough!

    So far so good

    I’ve only had this serum for a few days, so I will have to update once I’ve used the full bottle. When I first put it on, it absorbs really fast. I added my usual moisturizer on top. The next morning and night I used it again, under my moisturizer, and when I washed my face that following morning, I noticed my face is less dry and dull than it usually does. No weird smell and no skin reaction, so I will definitely continue using.

    Awesome!!

    This the is first face serum I've tried in a really long time due to my sensitive skin. I really love that it is so hydrating on my skin without making it feel greasy. I put this on after using a toner and before I put on my face lotion. My skin feels so plump and hydrated for hours after putting it on and most of all, it suits my skin.

    Calms my mind too

    This has really calmed my skin where others have failed. I have not used skincare in a while as everything seems to cause my skin to feel sensitive and uncomfortable. I didn't realise until now, how my sensitive skin was affecting my mood. Now that my skin feels less dry, red and sensitive, it seems to also help in calming my mind!
