Luckily, leaning on the words of fellow consumers is a trustworthy way of discovering products that actually work. Take the Dime Beauty Super Firm Serum: Countless reviewers unanimously agree that you'll "immediately feel a tightening sensation" and see "fast-acting results" on even the most stubborn fine lines. And right now, InStyle readers can try it for 20 percent off with the code INSTYLE20. Described by the brand as an "effective, needle-free option" for tighter, firmer, more lifted skin around the face, eye, and neck area, the serum leans on a unique blend of peptides to increase collagen production and elasticity in aging skin. In addition, the inclusion of leucojum aestivum, a rejuvenating plant extract, limits muscle contractions across these areas to prevent accelerated signs of aging — a benefit that has led reviewers to refer to the serum as "Botox in a bottle." Lastly, hydrolyzed rhodophycea extract, a type of antioxidant-rich red algae, leaves plump, supple skin in its wake.

"In many instances, you can feel an immediate tightening as the product dries," Dime Beauty wrote on its website. And while you may be inclined to think such a fast-acting effect is the handiwork of harmful chemicals, it's actually quite the opposite; Dime beauty ensures the ingredients used in its products are green-rated at 2 or less by the Environmental Working Group (EWG). Shoppers Say This Face Serum Makes "Deep Wrinkles" Disappear Despite researching skincare for a living, even I was blown away by the incredible results users have seen from the get-go. "Within two days, I could see results around my eyes and around my mouth," said one person, who claimed the fine lines they've had since they were 22 years old were noticeably filled in. "I'm 54 years old and I've used every skincare out there, from the least expensive to the most expensive, and Dime skincare is hands down the BEST," commented a second shopper. "This is a miracle in a bottle," shared yet another fan. "I use this in the morning and evening and I swear I already can't see [my] wrinkles! I had two forehead wrinkles, two between the eyebrows, and some crows feet, but now, [they're] GONE!" If you're dealing with pesky wrinkles that won't budge, give the Dime Beauty Super Firm Serum a go. Don't forget to use code INSTYLE20 at checkout for 20 percent off.
