Had high hopes
"I enjoy putting it on and have put it on every day since I got but I don’t see any brightening etc. Skin looks same and I haven’t used any Vitamin C for a long time. I’m not through yet with product so maybe it’ll turn a corner."

"I was so excited to try Bought the vitamin C combo. Loved it until the powder ran out twice as fast as the serum. I used as directed and was disappointed Any thoughts ? Willing to try again Thanks Anne"
Absolutely THE best!
"Best products on the market. Have subscribed to everything as their efficacy is incredible!"
Morning ritual
"I love using the vitamin C in the morning. My skin is looking more even and brighter, and it just feels light and fresh as I put it on my skin. I'll keep using to help even out dark spots, and it feels great under sunscreen!"
Only product that WORKS!!
"I’m 26 and have a hormonal imbalance. I’ve struggled with cystic acne and hormonal acne since I was 20. Nothing, and I repeat, NOTHING has worked on my skin. Dieting, supplements, water intake and temperature, skincare products, etc. At a Favorite Daughter event, I took home a goody bag that had a set of Exponent’s Vitamin C boost duo inside. It’s been 11 days… my acne is almost completely gone and so are my scars. I’ve never been so amazed and impressed by a product before. Not only did it work FAST, but it actually WORKS!! I’m so grateful for these products. Ordering more as soon as I run out. I almost lost all hope until now. Amazing skincare and definitely becoming a loyal customer."
"Great system for boosting vitamin C!"
"Refill for vitamin C serum."
Texture Game-Changer
"I have used this system daily now for the past month. I noticed a change within days. . . but the real miracle is that my husband noticed TOO! This is my forever Vit C."
Great concept, but difficult to control and prone to pilling
"I really wanted to love this product, but unfortunately it didn’t work well for me. I have a smaller face, and the amount dispensed with each pump feels excessive, which makes it seem like a lot of product is going to waste. I also experienced pilling when layering moisturizer on top. Even after waiting up to an hour to let the serum fully absorb, I still ran into the same issue, which was frustrating and again made it feel like I wasn’t getting the most out of the product. I do love the concept of the powder vitamin C for maintaining potency—it’s a great idea. I just wish there were more control over how much serum and powder is dispensed so it could be better tailored to individual needs."
Just what I needed…
