Basically, we worship the water that Terry de Gunzburg walks on.

The woman who created Touche Eclat for YSL...  What can we add?  (Terry was Creative Director there for years.)

And we are utterly devoted to - and constantly wowed by - her make-up creations.  On a recent visit to Paris, Jo even snuck into the By Terry boutique in the gorgeous, jewel-like Galerie Véro-Dodat, and made a few discreet lipstick purchases.  With her own money.  Which is either certifiable (considering we get sent hundreds every year), or the highest accolade a make-up artist could wish for.

It only remains to add that we're simply blown away by this amazing powder.  It looks like icing sugar in the tub, is actually cooling on the skin - and somehow moisturises, while leaving skin looking like velvet.  It's soft as a cloud, feels weightless - and ultimately doesn't leave you looking in the least dusty. (Though you have to give it a moment:  initially, the result is a bit 'white', till it somehow fuses with the skin and morphs into the perfect, complexion-matched shade.  Keep the faith;  it's worth it.)

Hyaluronic Hydra-Powder packed with skin-plumping hyaluronic acid which probably tops our list of all-time favourite cosmetic ingredients (and also works to nourish within:  we take it in supplement form).

We are not worthy, we are not worthy...  But Terry:  we're loving this, nonetheless.
