Guerlain 03N Naturel Lingerie de Peau
Guerlain 03N Naturel Lingerie de Peau ($63.00 for 1.0 fl. oz.) is the latest and greatest version of the Lingerie de Peau formula–it has been reformulated and now features 14 shades. The packaging was also updated to more of a rounded, square shape, which makes it easier to store, I think, and it is more comparable in diameter to many other liquid foundations on the market. The formula is supposed to be “invisible to the eye and to the touch” while “smoothing” and creating a “second skin.” It is a silicone-based foundation from what I can tell from the ingredient list. It has a very subtle floral fragrance–so subtle to my nose that I didn’t know it had fragrance until I checked for it.
Guerlain’s Lingerie de Peau is an exceptional foundation; I have always enjoyed it, and I’ve worn it extensively in its original formulation. I’m pleased to report that the reformulated version is excellent and has a comparable finish, wear, and blendability of the original. Where it differs is in the consistency: the new formula is much thinner and more like a liquid, whereas the original formula was more cream-like. I get more coverage faster with the original formula, but the new formula is more buildable from light to medium coverage. I wore them side-by-side one day, and other than that initial difference in application and cover, I couldn’t tell a difference between the two.
The new formula delivers buildable coverage from light to medium (about two layers), blends and spreads well across the skin and doesn’t sink into lines easily, sets and is touchable but still has a soft, natural finish, and looks like skin. I would actually agree that it made my skin appear smoother as well as more even in tone. The finish is just fantastic, as it doesn’t look overly dewy or totally matte but has enough luminosity to mimic the look of happy skin. The texture was thin, almost runny in a way, but it still yielded noticeable coverage in a single layer, which was easy to build upon as needed, whether all over or in specific areas. It took about a minute to two minutes for it to dry down, and it does look darker dried down than initially pumped from the bottle (true with the previous formula and most liquid formulas). I didn’t experience any oxidization or color changes throughout the day.
It wore well throughout the day, and it felt fuss-free because I often forgot I was wearing foundation at all–and that is the dream! It was easy to wear with or without setting powder, as it wore well and broke down nicely either way. The foundation was mostly transfer-resistant for me, even without setting powder, but if you are oilier, you might find it more likely to transfer. When I wore it on its own, it lasted for a solid ten hours with minimal signs of wear (slightly dewier but still even coverage). When I wore it with a setting powder, it lasted well for twelve hours. It wore long, and more importantly, well, because it was a gradual, even break down and doesn’t look oily, separated, or patchy at the end of the day.
Shade Range + Shade Tested
There are 14 shades available, and it is broken down into three groupings: cool (pink undertones), neutral (balance of pink and yellow undertones), and warm (yellow undertones). This is the most extensive shade range Guerlain has for any of its foundations, which is great news as the previous shade range was hard to fit into. However, the range could definitely use more medium-dark and darker shades (the range is more concentrated for fair to light-medium). I bought 03N Naturel to try, as I normally mix 02 Beige Clair and 03 Beige Naturel in Guerlain’s foundations (including the previous Lingerie de Peau formula), but I think 02N Naturel is going to be the better match as 03N Naturel is about a shade too dark on me. It matches the darker parts of my face but is noticeably different from my neck, so I’ve usually blended down my neck, just past my collarbone, which makes it wearable on me. 03N Naturel was more neutral in undertone compared to 03 Beige Naturel in the older formula, just slightly. I suspect I’ll grab 02N Naturel next time there’s a gift card event/sale.
For other foundation shades that I’ve tried, please see this FAQ, which includes my best matches as well as ones I have tried that are too dark/too light.
About My Skin
I have normal-to-dry skin, which tends to be mostly normal but occasionally has dry patches or spots around my upper cheeks, eyelids, and around the nose. I am not always dry in these areas, though. I consider myself light-medium in color with soft, warmer yellow undertones; I am not a true neutral (sometimes neutrals can look rosy on me), but foundations that are touted as warm-toned can lean too yellow on my complexion if they have fuller coverage. My neck is lighter than my face, while the edges of my face are darker than the center, so I try to match closer to my neck to minimize how far down I have to blend. While testing this foundation, I was mostly normal throughout and only had a bit of dryness around my nostrils.
