You can print away blemishes on your skin with Opté, a handheld wand made by Procter & Gamble Ventures.
"There's a camera that records at 200 frames per second. What that's doing is looking at your skin," said CNET senior editor Claire Reilly in a video online.
If it finds a freckle, maybe discoloration on your décolletage, it customizes and sprays a skincare serum from its many micronozzles to correct the perceived imperfection.
"...and it's kind of blowing my mind," Reilly added.
Reilly also says the company claims it can help fade the appearance of such flaws over time.
L'Oréal has the My Skin Track pH, a flexible adhesive sensor that communicates your acid-base balance to an app which recommends custom skin care products.
And send a selfie to Neutrogena's MaskID: in the mail, you'll get a 3D printed hydrogel mask customized to the contours of your face and infused with ingredients for your specific skin needs (when combined with the company's Skin360 add-on).
