I bought this duo having never tried either product before. I've been using both products for about two months now and am very happy with the results. (For reference, my skin type is dry [incredibly dry' and I am prone to get rosacea flare ups from BHAs.) The watermelon glow drops are a new staple in my routine and is one of those products I will forever have backups of. I never want to live without it again. The Vitamin C serum is definitely not the most potent and it has taken longer to see a difference in the darker spots on my face. However, it has a great texture that layers well with other products, something I found is not the case with the stronger vitamin C serums I've used in the past. I'd recommend this duo to anyone is curious, I highly doubt you'll be disappointed!
