C.E.O. Rapid Flash Brightening - Sérum

Love this, cannot be without it

Finally writing this review after using this product for years. I’ve tried other vitamin-C serums both expensive and cheaper and this is the one I come back too. I absolutely love it. It’s hydrating and there’s a noticeable difference in the evenness of my skin tone when I use this regularly. It’s my daily moisturizer and works well under makeup. moo but

The BEST

It’s fine! Don’t listen to these “OSHA “ warnings by these reviewers. Give me a break. The vitamin C in this product is very good but some people can’t tolerate Vitamin C. It doesn’t mean it’s an environmental hazard.

Vitamin C glow

Discover the magic of this incredible 15% vitamin C brightening serum—it truly glows in a bottle! The fragrance is delightfully subtle, making it a joy to apply. I adore its creamy texture, which feels luxurious in my morning and nighttime rituals. This serum doesn't just brighten; it plumps up my skin and keeps it radiantly glowing all day. It's a game-changer for my skincare routine!

DO NOT BUY THIS

I don't usually write reviews but this one is a necessity. This product should come with a warning and should be in OSHA's list of hazardous materials. MY FACE SWELLED UP AND TURNED PURPLISH RED, while my chest sprouted tons of red, angry hives that required a handful of Benadryl to control. It has been several days and the problem still exists which will require a visit to the dermatologist. I should send them the derm bill to pay.

Favorite vitamin c serum

I would to say that I am not loyal to any product and always changing to see if I can find something better but this one I continue to repurchase because it’s that good. I have sensitive skin and this does not make it angry

A staple for me

I absolutely love this stuff. I've tried a lot of vitamin c products, and a lot of them are really sticky and cause redness. this serum makes my skin so soft, supple, and clear. In my experience, it helped my breakouts and helped to reduce redness.

If you wanna glow, this should be you go to

I used this for a really important ceremony and my skin was glowing from this product alone! I would highly recommend it to anyone who is looking for a good brightening serum!

A nust have in my daily routine

After two weeks using the product my skin looks younger and hydrate more even tone I recommend this product

Love it!

This makes my skin glow and doesn't break out my skin. I have acne-prone, oily, sensitive skin and this doesn't irritate my skin.

Good product but not worth it

I love this product, but keep in mind that the container that you are actually looking at is not full. If you take the top off, it has a very small plastic bag with minimal product. It’s extremely misleading and for the cost I’ll be buying a different vitamin C from another manufacturer. I love Sunday Riley products, but you have to do better..

Overhyped

Overhyped not as effective as drugstore brands like Loreal.

My favorite!

I’m such a fan of this serum. A little goes a long way, and I’ve found that using too much can leave you looking a bit greasy, so start with one pump and apply more only if necessary. I have pretty “normal” skin with the occasional pimple, and wanted to brighten up my skin tone. I think this did a wonderful job - I’m on my fifth bottle already and have been using it in my daily skincare routine for years. Skin is noticeably brighter and looks super glowy after use.
