This Is the Cult Skincare Product That Sienna Miller Swears By for Glowing Skin

When it comes to deciphering whether or not a skincare product is actually any good, I fully understand how difficult it can be. Trying to work out exactly what claims should be taken seriously (and what should be written off as marketing gibberish) can prove frustrating to say the least. And when a luxury skincare product in question already has a lot of buzz around it and comes with a hefty price tag, it’s all the more likely for confusion to hit fever pitch.

Evidently, it seems this is exactly how a lot of people feel about SkinCeuticals C E Ferulic Serum (£165). Used by celebrities such as Sienna Miller and Hailey Bieber and loved by skincare experts and beauty editors far and wide, this rather expensive skincare product has caused quite the commotion in the industry over the last few years. In fact, I’d go as far as to say that this little bottle of serum has been my most asked-about product by friends and colleagues. It's one of the best SkinCeuticals products and sought-after vitamin C serums out there.

Hailey Bieber has previously shared that she uses SkinCeuticals C E Ferulic serum.

So does SkinCeuticals C E Ferulic Serum live up to the hype? First of all, I’d like to address the price tag. Yes, it is incredibly expensive, and I would never claim that anyone needs to spend £165 on a serum. However, I must admit that it is an unbelievably great product. Containing an extremely potent blend of vitamin C, E and ferulic acid this serum is widely considered one of the most efficacious antioxidant serums out there. It works to protect the skin from skin-damaging free radicals and helps brighten and reduce the appearance of existing pigmentation and fine lines.

Honestly, out of the hundreds of skincare products I have tried in my time as a beauty editor, nothing helps my skin quite like SkinCeuticals’ C E Ferulic. It helps even my complexion, improve skin texture and reduce dullness especially during the winter months when my skin can look a little lacklustre.

But a word of warning: This isn’t your typical luxury product. Typically, spending £100+ on a skincare product might buy you a deeply nourishing La Mer face cream or a rich La Prairie eye cream, however, purchasing this serum isn’t going to give you an at-home spa experience. It’s clinical skincare that means business—it’s formulated to treat your skin above anything else and it doesn’t come decorated in luxe packaging with a fancy smell or texture. It looks basic, but believe me, the results are far from it.

And personally, I think the results are what makes it such a hit among the A-list. It works to protect their skin from daily damage to ensure their complexions are at their most glowy day in and day out.

If there's one person who knows a thing or two about radiant skin, it's Sienna Miller, but that doesn't mean she doesn't have to work for it. Speaking to The Telegraph, she said, "I see the facialist Una Brennan, who operates out of her living-room in Notting Hill in London—I call it Una’s Chambers. It’s a pretty intense experience: She uses freezing ice masks that make you feel as if your brain is going to fall out of the top of your head. You look wonderful afterwards, though. Una got me on to SkinCeuticals C E Ferulic Serum and now I use it every day.”

Hailey Bieber took to her Instagram stories to reveal her current skincare lineup, including some products she’s been using for years. And what serum featured in her roundup? You guessed it. Alongside a picture of the SkinCeuticals C E Ferulic Serum, she wrote, "this serum is a favorite of mine.”

Besides the fact that it works to improve firmness and protect your skin from further damage, Jessica Chastain uses the serum to make her suncream work harder. Talking to Vogue, she said: "I read a while ago that if you put vitamin C on before sunscreen it makes the sunscreen more effective, so I do that. I like SkinCeuticals C E Ferulic. Just a couple of drops every day before sunscreen.”

We’re totally in awe of Brooke Shields's skin, and at 59, she puts it down to SkinCeuticals’ C E Ferulic Serum. She told Redbook, "I’m obsessed with SkinCeuticals C E Ferulic Serum. It’s packed with antioxidants and really brightens my skin, and since I began using it, I’ve noticed a difference in my fine lines.”

There are many things we envy about Tracee Ellis Ross, not least of all her radiant complexion. Thankfully, the actress took to instagram to share with us how she achieves it and it'll come as no surprise to you to hear, she owes it to SkinCeuticals C E Ferulic Serum. "I love me some skincare," she told us as she applied the serum allowing it to soak in before following with the brand's B5 Mask (£50) to lock in hydration.

In her Vogue Beauty Secrets video, Kendall mixed her SPF with SkinCeuticals C E Ferulic Serum. The two work together to provide superior skin protection from both UV rays and damage caused by free radicals.

Gwyneth Paltrow regularly talks about taking a less is more approach to beauty and a big part of that is great skincare. She's been rumoured to use SkinCeuticals C E Ferulic Serum as part of her rotation to keep her complexion radiant.
