It's sweltering outside. But if you're inside, in a chilly, over-airconditioned office (climate control indeed), perhaps you won't mind yet another peek at a Fall 2012 makeup and nail colour collection, this time from YSL.

Have you heard that YSL's famous Touche Éclat brightener pen (not a concealer), above, in its fancy 20th Anniversary packaging, has a new BFF? Launching this August is YSL Le Tient Touche Éclat ($60) -- Touche Éclat foundation.

Formulated with 39% water, 23% oils, plus pigments and light-weight gel for soft-focus blurring, 16 shades offer variations of pink-beige, beige and golden beige. (In Europe there are actually 22 colours. According to the YSL team at the launch, some of the shades are so similar that they felt they could leave some of them for later release.)

The foundation is free of alcohol, which is supposed to help the colour stay true on skin, and free of opaque fillers too, so coverage won't ever look ashy. A new foundation brush is coming out at the same time; watch for the launch of a new full range of brushes next year.

Also landing on YSL counters at Holt Renfrew, and select Bay, Murale and Sephora stores in August is the Fall 2012 colour collection. Here, at last week's preview, Ford model Andrea Deluca wears the look, applied by US-based YSL Beauty artist Dell Ashley.

Two eye shadow compacts include Pure Chromatics 4 Wet & Dry Eye Shadows in N° 10 ($74),  a gorgeous, wearable metallic golden khaki palette. (This is what Andrea is wearing.)

The Pure Chromatics N° 11 is a matte palette with shades YSL Creative Director of Makeup Lloyd Simmonds says are appropriate as liner, brow enhancers, or for matte smoky eyes.

These two liners, Dessin du Regard in N° 13 Saharan Bronze and N° 19 Graphite Green may not be available in Canada; you'll have to get a friend to pick them up in France for you.

Mascara Volume Effet Faux Cils Shocking in N° 1 Deep Black and N° 3 Bronze Black round out the eye makeup.

This is the collection's showpiece, the Palette Couture Highlighting Powder ($68).

The embossed trio of shades -- nude pink, golden beige and rosy brown -- serves to sculpt and highlight cheeks and temples, or blends together as healthy-glow blush.

Dare to Glow in N° 1 Tempting Gold, N° 2 Fatal Red, and N° 3 Naughty Pink ($55 each) are limited-edition luminizers that deliver sheer, subtle gleam.

The collection's lipsticks are variations on the iconic YSL red, and inspired by iconic rock groups. This one, Rouge Pur Couture The Mats LipstickNº 203 Rouge Rock ($38), is the YSL red, and was inspired by Queen.

The full range, available in Europe, consists of six Rouge Pur Couture The Mats lipsticks: Nº 201 Orange Imagine, Nº 2 Rose Crazy, Nº 203 Rouge Rock, Nº 204 Rouge Scandal, Nº 205 Prune Virgin, and Nº 206 Grenat Satisfaction. Oh, did you catch that? They're matte.

Canada will have the first, third and last shades: Nº 201 Orange Imagine (inspired by The Beatles), Nº 203 Rouge Rock and, available exclusively at The Bay, Nº 206 Grenat Satisfaction (inspired by The Rolling Stones). Add the rest to your list of requests for Paris-bound friends to bring back.

Of course you want both of these, YSL La Laque Couture Nail Lacquer in N° 32 Rouge Expressioniste and N° 31 Khaki Arty ($27 each).
