The pros say it's best to have two bottles of a foundation in different shades to mix and match throughout the year; but skin doesn't just change in shade, it can change in type and texture too. Case in point: my beloved NARS Sheer Glow started to sit a bit more heavily on my skin. Rather than setting it aside until it suited my skin again, I got my mixing hat on and found its perfect match.
Enter, YSL Le Teint Touche Éclat. I've never been totally happy with this foundation on its own. It's undoubtably a beautiful base, but the shades I have (B40* and B10 - warmer BD shades and cooler BR shades are also available) are just a little too cool for my skin and the finish just a little too glowy on oilier days. NARS Sheer Glow on the other hand is, as I think I've said before, totally mislabelled as it's neither sheer nor particularly glowy. This isn't usually a problem, but for whatever reason it was looking a little heavy and flat on my skin.
I found a 60:40 mix of Sheer Glow in Ceylan and Teint Touche worked best. The result was a more neutral tone than the Teint Touche shades alone, which blended out beautifully onto the skin and left a real 'lit from within', rather than too-glowy, look when unpowdered. The coverage is also very slightly lighter and the longevity better than Sheer Glow on its own. The only caveat is that Teint Touche contains SPF, so this mix might not be as good as NARS Sheer Glow alone if flash photography is involved.
Obviously buying two £30 foundations isn't ideal, although it's stretching out the dregs of my Sheer Glow, but I think this could also work well with something like Bourjois Healthy Mix Serum and Revlon Colorstay. If you're just wanting to add a bit more glow to your favourite base a touch of moisturiser, highlighter or even a couple of drops of face oil mixed in is also well worth experimenting with.
