This is my second time ordering. It reduces age spots and brightens my skin.

Helps my face glow again within two days. Amazing product!

The product is fine overall and I’d probably use it again. I bought the travel size as a trial but beware that there is just a tiny pouch attached to the pump, not an actual bottle. I’m pretty frugal with $$$ product and discovered this after about 10 days.

It took a week or two before I noticed any difference. I know it’s worth it when I look in the mirror with a clean face and it looks healthy and even. I follow up with a delicious moisturizer or face oil.

I have been using this faithfully for about 3 years. I saw it on QVC then bought it on Sunday Rily's site and elsewhere. I keep it in stock, back up in case I run out as I'm faithful with my skincare. I'm 68 now and people tell me often how good my skin looks. I also use a few of the other products but the C serum stand out the most since it doesn't make my skin react or have breakouts or whiteheads etc like others have in the past. It's a creamy serum and kind of hydrating for my dry skin but sinks in well. I use the Rich C cream during our cold months in PA and a different brand during warmer months over the serum. Very pleased with the stable properties this supplies and knowing I'm using a high % of a stable C for antioxidant protection. It also helps our sunblock work better. I read about that a few years ago what great news that was. I'm a Vit. C serum snob, at my age I've tried so so many but I'll continue to use this one as long as it's around! Note: I bought this myself I'm not an Influencer ;)

The results are amazing! Your skin actually glows. Not only am I hooked, but I have introduced my daughters, sister, PCP (former and current), pain Dr and dermatologist to this product. ALL of them use CEO serum and have their friends and family using it too. I’ve been a skin care junkie since the age of 15. I’m almost 67 and can honestly say Sunday Riley products are the best by far! My skin has never looked so good. Even a dermatologist told me that my skin looks good for 30 year old.

Purchased this for the first time about a month ago and I am very, very pleased with the results. I keep using this as I’ve seen a glow and softness in my skin.

To be honest, I love all of the Sunday Riley products but this might be my fave. I have been using this & the CEO Afterglow every AM for about 2 weeks and my 47 yr old skin has never looked so good. I'm so glad I added it to my routine.

All I can say is I wish I had taken a before pic! After about 10 days of using CEO Brightening Serum every evening, my pores have disappeared!! My makeup goes on smoother and my face is soft and smooth to the touch. I appreciate that it does not make my skin greasy, in order for it to be soft. I’ve also noticed that my skin doesn’t feel oily or dry like it used to.

Love the entire line of cosmetics everything is just exactly what they say. It is totally thrilled with the results.

I spent months looking for a new Vitamin C serum and found my way to Sunday Riley. LOVING the CEO serum. It's smells delightful and delivers all of the Vit C goodness I need in the morning.

2024-09-14

I love this product and use it every day. It makes my skin look glowy and fresh and works well under my moisturizer and sunscreen.

2024-09-12

Love the texture. Goes on smooth and you can tell the difference in just a few days!

2024-06-07

I love having this serum in my morning routine. It has a gentle citrus scent which I LOVE! I feel it contributes to the new glow I am experiencing since using Sunday's products. Try it!

II bought this serum over a month ago and can see a difference in the texture and smoothness of my skin. I may even look younger!

I am very pleased with my skin after using the 15% Vitamin C serum for a month. My skin is smoother, brighter and looks better. I highly recommend this product.

2024-03-04

I have bought this product a few times. I like the way my skin looks since I have been using it.

2024-01-01

I love this product. It is gentle and brightens up my skin after I have breakouts. I can’t go without it!
