What the gurus are saying

Stone carves out lip edges with precision and works brilliantly as an anchor for plumping glosses, making lips appear noticeably fuller. The trade-off is a tingling sensation that gurus find noticeable but bearable, and worth it if you're after that major plumping effect. Best suited for anyone who loves a bold lip outline and doesn't mind a little heat to get the volume.

"This one's Stone from Mac, and if you put that on the edges of the lips after you kind of dab off the gloss, your lips look humongous. If you're not into plumping lip glosses you will not like this, but if you are experienced and you want a major plumping effect, this is probably the most plumping gloss I've ever experienced. It works because it works so well."

"I'm using a much more cool tone liner, this is MAC Stone just to really carve out the edges of the lips. Then I'm going to [...] add a little bit of MAC Stone to that just so my lips don't look like they're floating."

"I used MAC Stone to do a little bit of contouring. I'd lost it for about six months because I put it away with my eyebrow pencils."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Vitamin C

Topical vitamin C is an antioxidant with reasonable evidence for dullness and uneven tone. It breaks down in light and air, so how a product is formulated and packaged matters as much as the percentage on the front.

Sunscreen filters

Sun protection is the best evidenced way to slow visible ageing, and the filters are what does the work. Mineral and chemical filters both protect when a product is applied thickly enough and often enough, which is where most people fall short rather than on the choice of filter.

Vitamin E

Vitamin E is an antioxidant, and it is often in a formula to keep the other ingredients stable rather than as the active itself. It pairs well with vitamin C, though on its own the evidence for visible change is limited.
