![]() The one thing I wasn't so fond of about the original version of Touche Eclat Le Teint was that its finish was a little too dewy for my taste and my skin type. These particles don't translate as shimmer when applied to the face though, so you don't have to worry about a disco ball effect. This is accentuated by the fact that my neck is considerably lighter than my face (I love scarves, what can I do.).īeyond the shade being a smidgen darker and the tone slightly warmer, I also noticed when swatching both on my arm that the new formula contains reflective particles that are visible to the naked eye, when the old version didn't. Right now, as spring has just started, it's a little dark for me in the old formula, and even more noticeably so in the new formula. But it's a bit unfortunate as B40 used to be an absolute perfect match for my summer skin tone. The difference is subtle enough that no one gave me funny looks when I was wearing both versions together, each on one half of my face. It's a smidgen darker and maybe even slightly warmer. I had the feeling when I first tried the new formula that my shade, B40, ran a little darker than before, and that impression was confirmed when I swatched both side by side. I still prefer to apply it with a brush for a smooth, even finish. It's not as watery as some serum-like foundations, such as Dior Nude Air Serum or even YSL Fusion Ink foundation, but it is light and quite runny. The new Touche Eclat Le Teint is similarly fluid and easy to spread out on the skin. I even wore the previous formula on half of my face and the new one on the other a few times to compare them thoroughly! Here are my thoughts: I alternated between the new and the old every day for a little while. ![]() To find out, I got a sample in the same shade I wear in the "old" formula, B40, and tested it out for a couple of weeks. Is it really going to be an upgrade, or is it never going to feel the same? I felt like a kid who sees someone take away their favorite toy to fix it, or replace it with something newer. But it could also ruin my newly found foundation love. If you are into vitamin C, you can take a look at more promising derivatives here.I had only just discovered my favorite foundation ever in Yves Saint Laurent Touche Eclat Le Teint for less than a year when I heard that YSL was about to come up with a reformulation. It is there in lots of products in tiny amounts (honestly, we do not really understand why), however, we do not know about any vitamin C serum featuring AP in high amounts. Overall, Ascorbyl Palmitate is our least favorite vitamin C derivative. Regarding the skin-brightening properties of pure vitamin C, this is another magic property AP does not have, or at least there is no data, not even in-vitro, about it. The only good thing we can write about Ascorbyl Palmitate is that there is an in-vitro (made in the lab, not on real people) study showing that it might be able to boost collagen production. ![]() It was only an in-vitro study meaning that it was done on cell cultures and not on real people, but still, this also does not support the use of AP too much. Third, another study that wanted to examine the antioxidant properties of AP was surprised to find that even though AP does have nice antioxidant properties following UVB radiation (the same one that comes from the sun) it also promotes lipid peroxidation and cytotoxicity. We are highly skeptical what effect a tiny amount of AP has in a formula. Even if it can be converted, the palmitate part of the molecule is more than the half of it, so the efficacy will not be good and we have never seen a serum that contains a decent (and proudly disclosed) amount of AP. This does not mean that ascorbyl palmitate cannot penetrate the skin (because it can, it's oil soluble and the skin likes to absorb oil soluble things) but this means that it's questionable if ascorbyl palmitate can be converted into pure Vit C in the skin. Second, a study that examined the skin absorption of vitamin C found that ascorbyl palmitate did not increase the skin levels of AA. A great study in the Journal of Cosmetic Dermatology compared a bunch of vitamin C derivatives and this derivative was the only one where the study said in terms of stability that it's "similar to AA". Ruscus Aculeatus Extract / Ruscus Aculeatus Root Extractįirstly, it's stability is only similar to that of pure ascorbic acid (AA), which means it is not really stable.
