L'oreal website as "instant smoothing results. Get the perfect skin texture, instantly and all day. The silky, lightweight formula glides onto skin and minimizes the look of pores and fine lines. Skin looks and feels smoothed and resurfaced. The result, a unifed matte finish that's flawless. Suitable for all skin types, dermatologist tested, non-comedogenic." Notice how it does not say that this base will help your makeup to stay on longer? I find almost every review of this product mentions how the user's makeup stayed on longer. I generally do not find that any primer actually helps my makeup to stay on longer, however, since my dry is dry I don't have the issue of my makeup disappearing or sliding off.
For dry skin, this just doesn't work for me, if I don't blend it in perfectly I notice that I get a film of it in areas of my face. As I said at the beginning of this review, primer should not have to take a long time to apply, and that's what bothers me about this product, it is tedious. Most of the reviews that I have read on this are from those with normal or oily skin, I would interested to see how other dry-skinned girls thought of this. In terms of performance like minimizing pores and fine lines, I think it did okay. Leaving my skin smoothed and resurfaced? It did feel nice on my skin, as far as resurfacing, I don't know how it could possibly resurface your skin. I would not re-buy this, it looks pretty in my bathroom amongst all the other products that I do not use. Nothing "magic" about this for me.
