What the gurus are saying

Water-light and gentle, this serum uses ester forms of vitamin C, which gurus say suits beginners and skin that can't handle the stingy classics. The trade-off: esters aren't the most potent form, so it's a softer approach. Fragrance splits the room, flagged as a real concern for reactive skin and called barely there by others. Morning, before sunscreen, is the suggested slot.

"The vitamin C complex is legit and the niacinamide concentration is genuinely really good, but the fragrance load in the brightening serum is a significant concern, especially for anyone with sensitive or reactive skin. Beautiful packaging, great ingredients, but the fragrance is something to definitely watch out for."

"She has her CC Serum, which is the vitamin C and niacinamide serum for 66 dollars. It is a vitamin C ester. It is not the active form of vitamin C, and it is extremely lightweight. I would say worthwhile trying for the morning time, especially if you have sensitive skin and you cannot tolerate a vitamin C. It's important to incorporate a vitamin C before applying sunscreen because it does make the sunscreen work better for you."

"Summer Fridays CC Me Vitamin C Serum [...] has their 30 ethyl ascorbic acid and escoro glucoside, two Ester forms of vitamin C. They're not necessarily the most effective forms of the Ester forms of vitamin C, but they're good for beginners or people with really sensitive skin."

"I love that it comes in a pump. [...] This one retails for 66 dollars and it's mixed with Niacinamide inside so just so that you guys are aware so that you don't waste your time going to buy another niacinamide product. It is a more watery component [...] compared to oilier ones like the CEO by Sunday Riley or the one by Allies of Skin. It has a very slight scent to it that doesn't actually bother me and it is a beautiful, beautifully formulated product, to be honest."

"Summer Fridays combines the form known as ascorbyl glucoside as well as the 3-O ethyl ascorbate form. Ascorbyl glucoside is [...] water soluble, so although it offers the same benefits as vitamin C in terms of antioxidant production and collagen production and pigmentation, the absorption is not great. I would say this form of vitamin C is one you would use in order to get more of that collagen-boosting effect."

"My first memory of the Summer Fridays Vitamin C Serum was being pleasantly surprised. [...] For me it's almost perfection in a bottle. It was different from other vitamin C serums because it was really light, it didn't have that synthetic feel, and it literally goes on the skin and feels like water."

"There are amazing Vitamin C serums around nowadays. Whether I like it or not, simply applying a Vitamin C serum in the same routine as my sunscreen is going to do my skin so many favors. My mind is stuck in the days of old, stingy Vitamin C serums that smelled like hot dog water and metal. I used to get really stingy skin and little red bumps. But those days are gone."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Vitamin C

Topical vitamin C is an antioxidant with reasonable evidence for dullness and uneven tone. It breaks down in light and air, so how a product is formulated and packaged matters as much as the percentage on the front.

Niacinamide

Niacinamide has evidence behind it for redness, uneven tone and supporting the skin barrier, and it is usually well tolerated even by skin that reacts to most things.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.
