Then I found this little gem by Clarins, the Double Fix' Mascara. The gel will make any mascara and eyebrow pencil waterproof. Result! No more under eye mascara smudges on a hot and humid day, don't get me wrong I like raccoons just don't like looking like one.
I had a little test under the shower (still not brave enough to try in dip in the English sea) and my mascara and eyebrow colour stayed put. The gel will also keep your unruly brows in check through any climate.
If all of this isn't enough you can also use the clear gel without mascara to condition your lashes and eyebrows, good for days when you don't want to wear any makeup, yes they do excists ;)
The buy of the summer if you ask me, £17 at your local makeup store.
