This ones the OG. Will never buy any other Vit-C serums, they don’t compare! I blind bought this four or five years ago because of Shani mentioning it’s benefits and effectiveness. It does exactly what it says, brightens and helps with scars. I was a deep picker so the spots on my face were endless, nothing worked. I started to use this Vit-C serum and instantly noticed them fading. I’m on my third bottle and will continue to purchase. In the am, this serum and Supergoop play SPF 50 is all I do. The best combo hands down for those stubborn dark marks and scars. Evens out my skin texture overall and brightens. Not to mention the glow is unbelievable. My skin isn’t as sensitive when using this and is deeply hydrated. Thanks Shani. All of your recommendations have been helpful.

Game changer for smooth, dewy skin and even tone to start day

I have only been using this product for a month but feel it is helping my fine lines and keeping my skin healthy looking. I intend to continue to use this product.

I love IS Clinal, their product actually works. My skin is glowing!!! Hormonal acne (from new IUD) is gone! Thank you thank you thank you!

I love how my skin feels after using this I have only had it it for a short time but so far I think it is a great product I have roscea & I think it is calming
