"This was the first retinol-based product I added back into my skincare routine postpartum, and I fully expected the usual cycle of irritation I’ve experienced with other retinol serums. But it never happened. It was the exact opposite, actually. My skin felt nourished, hydrated, and comfortable from the start. I've been using this serum for months and my 11 lines and forehead wrinkles appear softer and smoother."
"I love your skin care line for acne, am pore control, because really work to clean up my skin."
"Im 50 with aging skin, fine lines, wrinkles, dark spots. Im definitely the test subject for high end skincare. This Vit C is actually doing its job. I wear a full face of makeup and it plays nicely, no pilling. My dark spots are completely gone in some areas and fading in all areas. Skin looks brighter and firmer. I’m impressed and very happy to have found this Vit C because it’s affordable and working, finally!"
"My favorite vitamin C for dry skin"
"I love this product. it makes my skin feel so soft and ready for my moisterizer."
"I really like the Sunnyside C Glow Serum and that it has more vitamin C in it than most vitamin C serums on the market."
"Love it! So light and fresh."
"Best product"
"My dermatologist said I should be using a vitamin c product daily and recommended Skinceuticals. I have to say I loved it but didn’t like the $182 price tag. I tried this holifrog one and I think it works just as well and I love the feel of it and I especially love the price tag. I love it and am ordering it again!! Also, the other brand isn’t clean like holifrog is."
"Perhaps it's a bad batch but the Sunnyside serum does not feel like it absorbs into the skin. No matter how little I use, the serum just sits on my skin. When I apply the Grand cream after the serum, some areas on my face will pill up the serum. I like the ingredients but not a fan of the way it behaves. I've been hate using it for about a month now and have noticed that my skin isn't as smooth as it used to be. I'm also not a fan of the bottle because I'll need to take the lid off to reach the last of the serum. This should really be in an airless pump or squeeze tube. I don't think I would repurchase this product as is or recommend."
