I resisted buying SkinCeuticals CE Ferulic for about two years. The price put me off every single time I got close. I'd add it to my basket, see the total, close the tab, and go back to whatever vitamin C I was using instead. Then I finally bought it, properly frustrated with serums that promised a lot and delivered very little, and within a month I completely understood why people are so obsessed with it. I haven't looked for a replacement since.

This is my honest experience with it after using it consistently for about eighteen months.

Quick note before we get into it: if you're here just for the discount code, use LFTFNICOLAL at Lookfantastic for 20% off. You can find the full details on my Lookfantastic savings page. Now, here's why it's worth buying in the first place.

What It Is and Why It's Different

CE Ferulic is a vitamin C serum. That much you probably already know. What makes it different from the hundreds of other vitamin C serums out there is the specific combination of ingredients and the way they interact. It has 15% pure L-ascorbic acid, which is the most effective form of vitamin C for skin, plus 1% vitamin E and 0.5% ferulic acid. That last ingredient is the one that matters most. Ferulic acid stabilises the vitamin C and vitamin E, which means they stay active and effective in a way that most vitamin C serums simply can't match. Most budget options oxidise quickly and you end up applying an ineffective, slightly yellow liquid to your face every morning.

The pH is around 3.5, which is where L-ascorbic acid actually works. A lot of cheaper serums raise the pH to make them more comfortable to use, which also makes them considerably less effective. SkinCeuticals doesn't compromise on that.

Clinical data backs up an eightfold increase in the skin's natural antioxidant protection. That sounds like marketing copy but there's genuine peer reviewed research behind it. If you want to go deeper on antioxidants and how vitamin C fits into a broader routine, my vitamin C serum guide covers a lot of that ground.

What It Actually Does to Your Skin

I started using CE Ferulic every morning in October 2023, about four drops on dry skin after cleansing, before moisturiser and SPF. By week three I noticed my skin looked brighter, not dramatically, but consistently. The kind of difference where you stop reaching for a brightening primer because you don't feel like you need it.

By month two the sun spots on my left cheek, which I'd had for years and assumed were just part of my face now, had faded noticeably. That genuinely surprised me. I'd been using vitamin C for years and never seen that kind of result. The formula felt different on my skin too, slightly watery, absorbs fast, no stickiness, no strong smell. It settled in and that was it.

After eighteen months of consistent use: brighter overall complexion, faded pigmentation, and my skin just looks healthier in a baseline way that's hard to attribute to any single other product. I did also add SPF more consistently around the same time, and the two work really well together, antioxidant protection in the morning plus physical UV defence on top.

The Honest Downsides

The price is the obvious one. It is expensive and I won't pretend otherwise. You can get it for less via my SkinCeuticals discount page which takes a meaningful chunk off.

It does tingle slightly when you first start using it. That's the low pH doing its job. For most people it fades after the first week or two as your skin adjusts. If you have very reactive or compromised skin it might be worth starting every other day.

The packaging is extremely boring. Brown glass bottle, simple label. For what it costs you might expect something more impressive. You don't get it. The money goes into the formula rather than the presentation, which is honestly the right call, but worth knowing if you're the type who photographs your shelfie.

It can oxidise if stored badly. Keep it away from direct sunlight and heat. I keep mine in a bathroom drawer rather than on the counter and haven't had an issue. If it turns noticeably orange, replace it.

How I Use It

Cleanse, then while skin is still slightly damp I apply four drops across my forehead, cheeks and chin and press it in gently. Give it a minute to absorb. Then moisturiser, then SPF. That's it. Takes about thirty seconds to apply.

Morning only. In the evening I use retinol, and you don't want to layer those two together. If you're not sure how to structure your routine around actives, my guide on how to layer skincare products walks through the full order. And if you're looking for a good moisturiser to go on top, the Elemis Pro-Collagen range pairs brilliantly with an antioxidant serum in the morning.

One bottle lasts me about three to four months using it daily. When you work it out per use it's actually not as bad as the upfront cost suggests. If you're building out a full morning routine around it, I'd also recommend looking at Charlotte Tilbury's skincare line for finishing steps, there's a discount code on that page too.

How It Compares

I've tried a lot of vitamin C serums over the years and here's my honest take on the main alternatives:

The Ordinary Vitamin C Suspension: Cheap and widely available but the texture is gritty, it can pill under makeup, and in my experience the stability is unreliable. Fine for experimenting but I wouldn't use it long term.

Drunk Elephant C-Firma: One I genuinely liked for a while. Good texture, nice to apply, but I found it oxidised faster than CE Ferulic and the results plateaued after a few months. It's also not far off CE Ferulic in price, so I'm not sure the compromise is worth it.

Paula's Choice C15 Super Booster: Probably the closest to CE Ferulic in terms of the actual formula. Same 15% L-ascorbic acid, similar pH, similar ferulic acid stabilisation. The results I got were close, though not quite as strong on pigmentation. Worth trying if the price is the main barrier. Both this and Drunk Elephant are stocked at Sephora UK, and my Sephora discount page has 15% off if you want to try either first.

La Roche-Posay Vitamin C12: A gentler entry point, 12% vitamin C rather than 15%, and a slightly higher pH which makes it easier on reactive skin. I used this before graduating to CE Ferulic and it's a good stepping stone. Less dramatic results but noticeably kinder to sensitive skin.

If you're undecided, Paula's Choice is the closest alternative worth trying. But if you want the best performing formula I've personally tested over eighteen months of consistent daily use, CE Ferulic is it. Particularly for pigmentation, dullness, and anyone in their thirties thinking seriously about prevention.

Who Is It Best For

After using it on my own skin and recommending it to friends, here's where I think CE Ferulic really earns its price:

Pigmentation and uneven tone. This is where I've seen the most noticeable results personally. If you have sun spots, post-acne marks, or general unevenness that's been resistant to other products, the L-ascorbic acid at this concentration is one of the most evidence backed ingredients for fading it over time.

Preventative anti-ageing in your thirties. You're not going to reverse deep lines with a serum but consistent antioxidant protection from your early thirties genuinely slows the visible ageing process. CE Ferulic is one of the most studied products for this.

Anyone who wears SPF daily. Antioxidants and SPF work synergistically. The combination of CE Ferulic in the morning under sunscreen gives your skin significantly more protection than either does alone. If you're committed to SPF, this makes it work harder.

Normal to dry skin. The formula is designed for this skin type. If you have very oily skin it can work but some people find the slightly watery texture doesn't sit as well. Worth trying but be aware it's not specifically formulated for oiliness.

Questions I Get Asked

What's the discount code for SkinCeuticals?
Use LFTFNICOLAL at Lookfantastic for 20% off.

Can I use CE Ferulic with retinol?
Yes but not at the same time. CE Ferulic in the morning, retinol at night. They don't play well together in the same application. My retinoids guide goes into this properly if you're building that side of your routine.

Is it suitable for sensitive skin?
Generally yes, but start slowly. Every other day for the first two weeks, then daily once your skin adjusts. The tingle is normal and usually fades.

How do I know if it's oxidised?
It will turn a noticeably darker orange colour. Fresh CE Ferulic is pale yellow. If it's gone dark, replace it. Oxidised vitamin C won't harm you but it won't do much good either.

Is it worth the price without a discount?
Honestly, yes, if you're serious about your skin. But there's no reason to pay full price when the code is right there. Use it.

Does it help with pigmentation specifically?
Yes, and this is where I've seen the clearest results personally. It's not an overnight fix but consistent daily use over a few months makes a real difference to sun spots and uneven tone. Pair it with SPF every single morning and the results are significantly better.
