While there's certainly no shortage of products that claim to tackle dark spots and fine lines, you'd be hard-pressed to find one under $20, let alone under $10. So when we noticed an army of over 13,000 Amazon shoppers singing the praises of one vitamin C-packed serum, we were intrigued — and the sticker price just sealed the deal. It's on sale for $7! We'll wait while you pick your jaw off the floor.
The Eclat Skincare Organic Vitamin C Serum is made entirely of plant-based ingredients, like aloe vera juice, witch hazel, jojoba oil and hydrating hyaluronic acid. It's also loaded with good-for-your-skin vitamin C, and according to customer tests, 94 percent saw an increase in skin smoothness, softness and health after using the serum for 10 days.
The magic is in the concentration of vitamin C. Many other serums on the market contain 15 percent concentration, which isn't enough to make a difference, or upwards of 22 percent, which can be more irritating than beneficial. The Eclat Skincare formula sits pretty at 20 percent vitamin C, so it's effective without being overpowering, especially on sensitive or delicate skin.
If you're battling dark spots — whether caused by the sun, aging, or acne — the serum can help lighten them.
Writes one shopper: "This has significantly faded the stubborn dark spot on my forehead, so I'm thrilled about that," she shared. "I also love how this feels on my skin. It's very hydrating with a thick consistency, but it doesn't feel sticky. The ingredients list is great and you can't beat the price."
Others have noticed a decrease in fine lines:
"Since using this vitamin C serum I have definitely noticed that my fine lines have significantly reduced around my eyes and forehead," one shopper gleefully reported. ..."The roughness on my cheeks seems to be a lot better! I am in love with this product!"
Shoppers sensitive to smells rave about the serum as well, praising its fresh fragrance.
'First off, it smells amazing," one wrote. "Lovely light citrus scent. Not too greasy. My skin is already more even and the fine lines around my chin look better."
In short, shoppers are in love — and astonished. "Is this a joke? I used this once—ONCE—before bed...washed my face, applied this serum, and finally applied my normal moisturizer and retinol," says a five-star shopper. "...I woke up absolutely glowing to the point that people were complimenting me...My skin is so soft and radiant, I’m terrified that people will catch onto this and it’ll run out of stock. How is it possible that a serum could do this? Mind blown."
