Me: 24, sensitive skin, combo/oily. I'm a MAC NC20, and Graftobian's Ingenue shade fits me perfectly.
The product: There are a few ways to go about trying this. Several websites, such as camerareadycosmetics.com, offer samples. I've heard those samples are tiny, so I avoided that. If you're confident of your shade, you can buy a pot of it for only around $12. I opted to buy the Warm #1 Palette for $20, and I'm glad I did. Each shade is a small size, but you use up so little of it each time that it will last you a long time! And it's a great way to figure out what shade you are.
My experience: I really love this! I've always heard negative things about "pan makeup", but this is meant for HD, where all of your flaws are on sharp display, and so it looks nothing like the cakey, obvious stage makeup of yore. I've tried RCMA foundation in the past and found it very dry and cakelike, but Graftobian HD Creme is creamy and easy to spread.
The only thing I DON'T like about this is that it does not look nice over my silicone-based sunscreen. This is why Graftobian has a mattifying setting spray, instead - this foundation is meant for a moisturizing primer, NOT a mattifying primer. If you do need a mattifier or something to help it set, whether in powder or spray form, it goes on top. It does apply well over my non-silicone based sunscreen, which is Burnout Eco-Sensitive SPF 32.
To apply the HD Creme, I use three different products: the foundation itself (obviously!), a BeautyBlender sponge, and Reviva Labs Rosewater Facial Spray.
For a sheerer but 100% flake-free and foolproof application, I moisten the BeautyBlender, dot the foundation around my face, spritz my face with the Reviva spray, and then buff it all in with the large end of the BeautyBlender. Once it's been blended in, I mist my face with the spray again and leave it at that. Both the damp BeautyBlender and the spray sheer out the foundation a little, but it melts into my skin perfectly.
For heavier coverage, I spritz my skin with the rosewater spray and wait for that to sink in. I dot my face with the HD Creme and buff with the BeautyBlender, following up with a spritz once I am finished.
This DOES lack staying power, but I've found that buffing pure silica powder on top works like a charm for getting this to set and stick for hours.
