They say you always remember your first, and that is absolutely correct. Radha Beauty's rosehip oil was one of the first skincare products I covered that really got InStyle readers talking, and according to shoppers, the brand's done it again with its Vitamin C Serum: The brightening, wrinkle-reducing fluid is so potent, shoppers say they haven't worn makeup in years.    

That's impressive, especially for a serum that currently goes for $15 (and even its non-sale price is only $18). Looking through the reviews that go with its roughly 3,000 five-star ratings, all of 118 glowing testimonials mention the formula's effect on fine lines and wrinkles. And the difference is so pronounced, multiple people in their 40s said it makes them look 10 to 20 years younger.   

Those in their 50s echo the praise: As one such user wrote, the ultra-light gel serum significantly decreased their neck wrinkles, and made the ones on their chest "completely disappear." As a different commenter said, "It's one of those rare products where you can see a noticeable difference as soon as you use it," thanks to the well-rounded ingredient list — and per more fans, it improves their skin in a matter of three to five days.

Unsurprisingly, brightening vitamin C is at the serum's heart. The formula gets a moisturizing boost from glycerin, hyaluronic acid, and aloe, while green tea extract, ginseng extract, ginger extract, and vitamin E add free radical-deterring antioxidants. And if your pores are top of mind, witch hazel water recruits its trademark pore-minimizing, redness-eliminating impact into the mix.   

With that blend of gentle but hard-working ingredients, it's no wonder that even a 70-year-old shopper said it keeps their skin looking like it did in their 50s. Three dozen five-star reviewers also highlighted how well it lightened their age spots, compelling one person to write, "It must be witchcraft...this stuff is incredible." Per a penultimate customer, the under-$20 buy worked faster than their go-tos from Lancôme and Estée Lauder — and didn't feel oily to boot.   

"Hands down, [I] have noticed a huge difference in my skin," wrote a last enthusiast who is going on five years with the product. "Stop using filters — get the real thing." Try the Radha Beauty Vitamin C Serum for $15 while it's on sale at Amazon.
