the weirdest thing about being a beauty bible tester is having to test a product on only one side of your face - so you have a good & fair comparison agains whatyou usually use. (in fact it's a habit I can't break now.... I bought the Perricone TSV - believeing the hype that it will work, but I'm only using it on one side of my face and in 30 days I'll deceide whether it's worth keeping or will be going back)
I've been testing for a few years for beauty bible and I've never found any of the anti-aging products to do anything other than moisturise.
My current load I'm testing is :-
Emma Hardie Rejuvenating Night Cream
Filorga Foam Cleanser
MeruMaya Intensely Youthful Eye Cream
L'Occitane Instant Hydration Mask
Elemis Pro Radiance Hand & Nail Cream
Una Brennan Neroli Firming Super Lift SPF15 Day Cream
Lavera Neutral Sun Milk SPF20 Medium
Dermalogica Daily Microfoliant
M&S Pure Ultra Soothing Lip Balm
NYX Fly with Me Mascara (Jet Black)
And they're all full sized products.
I'm happy to pay a bit towards the p&p & admin to get to try some products I'd never get round to trying under my own steam.
