I bought this product on recommendation from Lisa Eldridge on YouTube, plus I was looking for a hyaluronic acid serum to replace the much hyped HYDRALURON serum I had used up - and didn't see any significant difference with, might I add. I didnt have too high hopes for this, however, this serum quite literally changed my skin overnight. I am now onto my second bottle and cannot imagine being without it. The consistency is very runny, almost like frozen vodka (if that makes sense) watery but with a gel like element. It completely absorbs into the skin and I apply my day or night moisturiser straight over top. It doesn't interfere with makeup or any of my other skincare steps. It has no smell, colour or irritating ingredients, which is also why I bought it over the skincueticals serum. It's also half the price! Although I have combination skin, It gets very dehydrated in winter and this serum has saved it - I no longer get rosacea like bumps on my cheeks due to irritation or dryness. My skin is smoother and retains moisture much better than when I do not use it under my moisturiser. I can honestly say this has become a staple in my daily skincare routine and its a shame it isn't more widely available. Try it - you will not be disappointed.
