Sunday Riley C.E.O. 15% Vitamin C vs OLEHENRIKSEN Banana Bright 15% Vitamin C is not a hard Sephora comparison once you separate the formula style from the marketing.
Sunday Riley is the better fit if you want a richer, stability-first serum that stays comfortable on dry or easily irritated skin. OLEHENRIKSEN is the better fit if your main goal is brighter-looking dullness, smoother texture, and more direct dark-spot support.
If you want the shortest possible answer: Sunday Riley is the safer comfort pick, OLEHENRIKSEN is the more active brightening pick.
| Product | Price | Size | Vitamin C type | Texture | Best for |
|---|---|---|---|---|---|
| Sunday Riley C.E.O. 15% Vitamin C Brightening Serum | $115 | 1 oz / 30 mL, also 1.7 oz / 50 mL | THD ascorbate | Richer, cushiony, stability-first | Dry skin, sensitivity, comfort, simpler brightening |
| OLEHENRIKSEN Banana Bright 15% Vitamin C Dark Spot Serum | $70 | 1 oz / 30 mL | 3-O-ethyl ascorbic acid + 5% PHA + hyaluronic acid | Lighter, glowier, quick-absorbing | Dullness, texture, dark spots, makeup-friendly glow |
Quick verdict
If you want one serum that is easier to live with every day, pick Sunday Riley. It is the calmer option, the richer option, and the one that makes the least fuss under moisturizer.
If you want a serum that pulls more weight on dullness and rough texture, pick OLEHENRIKSEN. The added PHA gives it a more obvious resurfacing angle, which is why it often feels more targeted for dark spots that sit on top of texture.

Sunday Riley C.E.O. 15% Vitamin C vs OLEHENRIKSEN Banana Bright 15% Vitamin C
Both serums are built around stable vitamin C derivatives, but they are not trying to do the same job.
Sunday Riley uses THD ascorbate, which is oil-soluble and designed to feel more nourishing in the skin. The formula also leans on squalane, phytosterols, and barrier-supporting ingredients, so the experience is more about brightening without making the routine feel sharp.
OLEHENRIKSEN uses 3-O-ethyl ascorbic acid, plus 5% PHAs and hyaluronic acid. That makes it the more active-feeling formula. It is still positioned as a daily serum, but it is clearly built for brightening plus light exfoliation, not just vitamin C alone.
Topical vitamin C has real evidence for helping uneven tone and photodamage over time, but it is not an instant fix. A Cleveland Clinic overview and a PubMed systematic review both point in the same direction: the ingredient is useful, but consistency matters more than hype.
Formula and ingredient differences
Sunday Riley is the more stability-first formula. THD ascorbate is the centerpiece, and the supporting cast is built around comfort: squalane, glycerin, saccharide isomerate, and phytosterols. It also includes glycolic acid, but the overall feel is still closer to a nourishing serum than an exfoliating one.
OLEHENRIKSEN is the more corrective formula. Along with 15% vitamin C, it brings in 5% PHAs and hyaluronic acid, which means the formula is doing three things at once:
- Brightening with vitamin C.
- Gently smoothing with PHA.
- Replenishing hydration with hyaluronic acid.
That is why it tends to make more sense when dullness and dark spots come with roughness, not just discoloration.
Fragrance sensitivity is where the gap matters most. Sunday Riley is labeled fragrance-free on its product page, and it is the safer starting point if your skin tends to react to scent. OLEHENRIKSEN is less forgiving here: the brand says the formula contains less than 1% fragrance from oranges, and the ingredient list includes orange-derived scent components. If fragrance usually bothers you, that is not the first serum I would choose.
Texture and finish
Sunday Riley feels richer and more cushioned. It spreads like a serum that wants to behave a little like a treatment oil, which makes it more comfortable if your skin gets tight or dry during the day.
OLEHENRIKSEN feels lighter and faster. It leaves a luminous finish that makes sense under makeup and in morning routines where you want glow without weight.
That usually turns into a simple preference:
- Choose Sunday Riley if you want comfort first.
- Choose OLEHENRIKSEN if you want a brighter finish first.
Skin-type fit
Dry or dehydrated skin usually does better with Sunday Riley. The richer base and THD ascorbate make it easier to keep the routine stable without adding extra layers just to offset dryness.
Normal or combination skin can go either way. If your main complaint is dullness and you want more visible smoothing, OLEHENRIKSEN has the edge. If you want a serum that disappears into the routine and stays quiet, Sunday Riley is simpler.
Sensitive or fragrance-reactive skin should start with Sunday Riley, but still patch test. That is the more conservative choice, not a guarantee of zero reaction.
If you are deciding whether your routine needs another brightening serum at all, niacinamide vs hyaluronic acid for glass skin is the better comparison to read first.
Price and value math
The price gap is real. At Sephora, Sunday Riley is $115 for 30 mL, while OLEHENRIKSEN is $70 for 30 mL. That means Sunday Riley costs about $3.83 per mL and OLEHENRIKSEN costs about $2.33 per mL.
In plain English, Sunday Riley is about $45 more per bottle and roughly 64% more expensive per mL. That does not automatically make it worse value. It just means you should be honest about what you are paying for: a richer feel, a more comfort-first formula, and a less aggressive user experience.
If you use a serum every morning and finish a 30 mL bottle in about three months, the rough monthly spend is about $38 for Sunday Riley and $23 for OLEHENRIKSEN. That is the kind of math that matters for a product you might repurchase three or four times a year.
For a routine that already has a cleanser, moisturizer, and sunscreen, the better value is usually the serum you will actually use consistently. That is why how to build a skincare routine you will actually follow is the right companion read here.
Routine placement
Use either serum in the morning after cleansing and before moisturizer and sunscreen. That keeps the routine practical and matches how vitamin C is usually used in real life.
If you are new to OLEHENRIKSEN, start every other morning so you can see how your skin handles the PHA component. Sunday Riley can usually be used more freely, but there is still no reason to rush into overuse if the rest of your routine is already active.
A simple order works best:
- Cleanse.
- Apply vitamin C serum.
- Moisturize if needed.
- Finish with SPF.
That is also the point where the routine should stay boring. If the serum pills, stings, or makes everything feel too heavy, simplify the rest of the stack before blaming the vitamin C.
Morning routine fit
Sunday Riley fits a morning routine that is meant to be low-friction. If you want one treatment step before moisturizer and sunscreen, and you do not want to think about whether your skin is going to complain, it is the easier serum to keep in rotation.
OLEHENRIKSEN fits a morning routine that is more about visible payoff. If you want the serum step to do a little more work on dullness and rough texture, it earns its place better when you are not already using a long stack of other actives.
In practice, that means Sunday Riley works well for people who keep the AM routine to cleanser, vitamin C, moisturizer, SPF. OLEHENRIKSEN works better if you like a brighter finish and are okay with a formula that has a little more texture-correction personality.
If the rest of your morning routine is already busy, keep the vitamin C slot simple. This is the place where overcomplicating things usually backfires.
Sensitivity and fragrance tradeoffs
This is the most important difference for a lot of buyers. Sunday Riley is the safer starting point if your skin is reactive, because it is fragrance-free and built to feel calmer on contact. That does not mean it is impossible to react to, but it does remove one common irritant from the equation.
OLEHENRIKSEN is less neutral. The brand is explicit that the formula contains less than 1% fragrance from oranges, and some people will like that because it gives the serum a more polished sensory profile. Other people will want nothing to do with it. Both reactions are reasonable.
If you have a history of reacting to fragranced skincare, Sunday Riley is the better fit. If you do fine with lightly scented products and want the more obvious brightening-plus-resurfacing formula, OLEHENRIKSEN still makes sense.
Who should skip it
Skip Sunday Riley if you want the strongest possible surface-level resurfacing from a vitamin C serum. It is not the most aggressive option in Sephora’s lineup, and paying extra for its comfort-first profile will feel wrong if your priority is the most immediate visual change.
Skip OLEHENRIKSEN if your skin is fragrance-reactive, very easily irritated, or already overwhelmed by exfoliants. The PHA plus fragrance combination is not extreme, but it is still less forgiving than the Sunday Riley option.
You may also want to skip both if you already have a vitamin C serum you tolerate and use consistently. There is no award for replacing a working routine with a shinier bottle.
What kind of buyer each one fits
Sunday Riley fits the buyer who wants comfort first
This is the person who usually buys based on feel as much as results. They want a serum that layers well, does not fight moisturizer, and does not make their morning routine feel like an experiment.
It also fits the buyer who is cautious about fragrance, has dry skin, or has had bad luck with harsher brightening products in the past. If your main complaint is that your skin looks tired, not that it is rough, Sunday Riley is the cleaner match.
OLEHENRIKSEN fits the buyer who wants more visible correction
This is the person who wants the serum to do something extra. They are usually looking at dullness, texture, and dark spots at the same time, and they are fine with a formula that feels more active.
It also fits buyers who like a brighter finish in the morning and want something that reads more like a treatment step than a comfort serum. If you want the routine to feel a little more targeted, OLEHENRIKSEN is the better buy.
Similar Sephora alternatives and related products
If neither of these feels exact, Sephora has several related options that cover nearby use cases. The most obvious adjacent comparison set is on Sephora’s Daily Vitamin C Serums page.
For a more classic daytime vitamin C serum, Drunk Elephant C-Firma Fresh Vitamin-C Day Serum is a relevant reference point. For a lower-cost entry point, The Ordinary Ascorbyl Glucoside Solution 12% is the obvious budget alternative. If you want something in the same brightening lane but with a different texture and positioning, Sephora also surfaces Paula's Choice C15 Super Booster on its vitamin C and ferulic acid pages.
As a general rule, the comparison should be about the job, not the brand. If you want the gentlest path to more even tone, look at lighter vitamin C derivatives. If you want a brightening serum that does more visible smoothing, look at formulas with supporting acids. If you want a more comfort-first brightener, Sunday Riley stays the easier choice.
Final verdict and FAQ
The better serum for most dullness-plus-dark-spot routines is OLEHENRIKSEN Banana Bright 15% Vitamin C. It is more direct if you want brightness plus texture help, and the added PHA makes the formula feel more targeted.
The better serum for dry, sensitive, or fragrance-cautious skin is Sunday Riley C.E.O. 15% Vitamin C. It is the safer, richer, more stability-first option, and it asks less of the skin.
If I were narrowing it down to one line: choose OLEHENRIKSEN for more visible glow and resurfacing, choose Sunday Riley for more comfort and less risk of irritation.
Which one is better for dark spots?
OLEHENRIKSEN is the more obvious choice if dark spots are paired with dullness or rough texture. Sunday Riley is still a good option, but it is more of a comfort-first brightener.
Which one is better for sensitive skin?
Sunday Riley, as long as your skin still tolerates it. It is the calmer formula, but you should still patch test because fragrance reactions and vitamin C reactions are different problems.
Which one is better for a morning routine?
Sunday Riley is the easier daily AM pick because it is quieter on the skin and less likely to compete with moisturizer or sunscreen. OLEHENRIKSEN is still a morning product, but it makes more sense if you want the serum to do more than brighten.
Can I use these with the rest of my routine?
Yes. Keep the rest of the routine simple and consistent. If you want the rest of the system to feel easier to stick with, how to build a skincare routine you will actually follow is the right starting point.
Which one is better value?
OLEHENRIKSEN is the better value on paper because it is much cheaper per mL. Sunday Riley only makes sense as the value choice if you personally prefer the texture enough that it helps you stay consistent.
What if I only care about glow?
Pick OLEHENRIKSEN. It is the more visibly luminous formula and the one that reads as a brightening serum first.
What if I want the safest pick for dry skin?
Pick Sunday Riley. It is the better fit when the routine has to feel comfortable first and brightening second.
