Hand sanitiser is fantastic! I don't know of anyone that doesn't use it to be honest! You don't need water, and it dries within seconds to leave you with clean hands, not only visibly but they genuinely feel clean too.
I love that the Dettol hand sanitiser had two different sizes of the bottles. A bigger pump one for at home and the smaller ones which are perfect for chucking in your bag or the car! The scent is nice too - a fresh scent. And it's not too overpowering which is great.
One thing I'd be wary of, is if you have sensitive skin. I sometimes get dermatitis on my fingers and the sanitiser aggravates it further because it does have the alcohol in it. But if you don't have any issues like that, it's a must buy!
I have purchased both the large size bottle and the convenient small size which is perfect for having in your handbag or for travel. Whilst it is great to have this waterless option for sanitising hands which was indeed refreshing and absorbed easily, I found that after using it for awhile my hands and nails became very dry and I had to keep applying more and more moisturiser to counter balance the effects. Eventually I had to stop using the Dettol Healthy Touch Hand Sanitiser Instant Refresh and focus on restoring my hands and nails with moisturiser. I probably won't buy this product again.
