SkinCeuticals often sits on the top shelf of dermatologists’ offices for good reason: science backed formulas, minimalist packaging and a track record of products that generally do what they say they will. The latest jar to tempt my bathroom cabinet is Glycolic 10 Renew Overnight, a name that sounds part chemistry lesson part bedtime story.
The brand promises that this corrective cream uses a punchy 10 percent free acid value of glycolic plus 2 percent phytic acid at a low 3.5 pH to speed up cellular turnover while you sleep, nudging dull skin toward a smoother brighter finish. They also add a “Soothing Complex” to keep irritation to a minimum so you can supposedly wake up glowing rather than peeling.
To see if the claims match reality I slotted the cream into my nightly routine for a full two weeks, following the recommended every other night start then moving to nightly use. The goal was simple: measure glow factor, texture improvement and overall skin comfort so you can decide if your wallet should get involved.

What Is Glycolic 10 Renew Overnight?
Glycolic 10 Renew Overnight sits in the overnight treatment category, meaning it is designed to work while you sleep rather than during your daytime routine. Overnight treatments usually feature higher concentrations of actives because skin is less exposed to sunlight and environmental stressors, giving ingredients a clear window to do their job without interference.
This cream relies on a 10 percent free acid value of glycolic acid, an alpha hydroxy acid known for loosening the bonds between dead surface cells so they can shed more easily. By clearing that buildup, glycolic acid encourages fresher cells to reach the surface for a smoother, more even look. The formula pairs it with 2 percent phytic acid, an antioxidant that also offers gentle exfoliation and can help reduce the appearance of discoloration over time.
With a pH of 3.5, the product keeps these acids in an effective range for exfoliation. A proprietary Soothing Complex rounds out the mix, aiming to buffer potential irritation that can come with acids by supporting the skin barrier. The goal is a moderate yet consistent uptick in cellular turnover that translates to improved tone and texture by morning.
Did It Work?
In the name of science I benched my usual retinol night cream for a few days before starting Glycolic 10 Renew Overnight, imagining lab coats and clipboards while I cleared my skin’s schedule. Fourteen days felt like a fair window to judge any real change so I committed to the every other night ramp up during week one then switched to nightly use in week two, always on freshly cleansed skin followed by a simple ceramide moisturizer.
Night one delivered the familiar tingle of glycolic but no stinging or redness by morning. My skin looked a touch brighter, the way it does after a good cleansing brush session. Nights three and five were similar: slight warmth on application followed by a smooth finish once the cream settled. I appreciated that the texture is more lotion than acid peel so it never dripped into corners or eyes.
By the halfway mark I noticed makeup gliding on a bit easier and the tiny bumps along my jaw felt flatter. However any glow boost plateaued quickly. I kept waiting for that “did you get a facial” radiance the marketing hinted at but the mirror gave me a polite nod rather than applause.
Week two, now on nightly use, introduced some flaky patches beside my nose despite layering a barrier cream on top. They were minor and cleared with a hydrating mask yet the promised Soothing Complex did not fully spare me. On the upside no breakouts or purging appeared, which is impressive given glycolic’s tendency to stir the pot.
End of day fourteen tally: texture is marginally smoother, one stubborn post-blemish mark looks lighter and my complexion sits at a healthy medium shine. It works, just not spectacularly. If you have never used acids this could be a gentle entry point, but as someone with a roster of brighter, cheaper exfoliants I am not rushing to hand it permanent residency on my shelf.
Main Ingredients Explained
The headline act is 10 percent free acid glycolic acid, a small molecule alpha-hydroxy acid that slips between dead surface cells and loosens the “glue” holding them in place. At the low pH of 3.5 it is active enough to speed up turnover yet, for most people, stops short of the spicy burn that higher strengths can cause. Because the free acid value is clearly stated you know exactly how much exfoliating power you are getting rather than guessing at total glycolic content.
Backing it up is 2 percent phytic acid, an antioxidant extracted from grains and legumes. Phytic chelates excess iron in the skin which can reduce the look of stubborn discoloration, and it has gentle exfoliating chops of its own. Think of it as a polishing cloth that follows the sandpaper of glycolic, subtly brightening without piling on extra irritation.
The proprietary Soothing Complex is a mix of jojoba esters, sunflower seed wax and acacia flower wax that behaves like a breathable blanket, limiting transepidermal water loss and cushioning the skin barrier. Dimethicone and its cousins sit alongside these natural emollients, giving the formula that silky glide. While dimethicone has a reputation for feeling occlusive it rates a low 1 on the comedogenic scale, meaning it is unlikely to clog pores unless your skin is extremely congestion-prone. (Comedogenic simply refers to an ingredient’s tendency to block pores and trigger blackheads.)
Worth noting are the supporting players: salicylic acid at a whisper-low level to keep pores clear, aluminum starch octenylsuccinate for a soft-focus finish and tocopherol (vitamin E) for antioxidant backup. The INCI list shows no animal-derived components so the cream is suitable for vegans and vegetarians, though SkinCeuticals is not a strictly vegan brand overall.
Pregnancy safety sits in the gray zone. Low-strength glycolic and the trace salicylic acid are generally regarded as acceptable in topical use, yet most dermatologists still recommend pausing active acids while expecting. If you are pregnant or nursing have a quick chat with your doctor before adding this to the nightstand.
Finally the formula is fragrance free which helps keep sensitization risk low, and the airless pump jar protects those acids from light and oxidation so you get consistent potency from first pump to last.
What I Liked/Didn’t Like
After two weeks of nightly use here is the straight pros and cons rundown.
What Works Well:
- Noticeable overnight smoothness that makes morning makeup application quicker and cleaner
- Clear listing of 10 percent free acid glycolic so you know the active strength without decoding marketing fluff
- Fragrance free silicone cushioned texture glides on easily and plays nicely with a simple moisturizer layered on top
- Airless pump keeps the pH stable and the cream fresh from first pump to last
What to Consider:
- Glow improvement plateaued after the first week so seasoned acid users may crave more punch
- Some dryness around the nose despite the built in Soothing Complex so very sensitive skin may need extra barrier support
- Price sits at the premium end of the skincare aisle which can be hard to justify given the moderate results
My Final Thoughts
Glycolic 10 Renew Overnight lands in that competent middle ground where science meets sensible expectations. After two weeks I can confirm it behaves exactly like a well formulated 10 percent glycolic cream should: a nudge toward brightness, a subtle smoothing of rough patches and the occasional dry corner that asks for extra moisturiser. On my personal thrill meter that translates to a solid 7/10. I would pass the jar to a friend who is new to chemical exfoliation or is hunting for a fragrance free option that will not wage war on their skin barrier. Seasoned acid aficionados or anyone chasing dramatic before and after selfies may find the payoff polite rather than party starting.
Finding the right overnight treatment is a bit like picking a mattress, you only know it is wrong after a few restless nights. I have cycled through more night creams and sleeping masks than I care to admit so I feel comfortable saying I gave this one a fair shake. The formula is well balanced, the airless pump is hygienic and the irritation level low, yet I kept wishing the promised glow were just a notch louder. That is hardly a crime, just a reminder that marketing speak is fluent in optimism.
If Glycolic 10 feels a smidge too clinical or pricey, there are worthy benchmates. Nocturnal Revive Cream by Deascal is an excellent allrounder I have on permanent rotation, folding hydration, gentle resurfacing and barrier support into one wallet friendly pot. For a lighter water gel texture that still leaves skin plush by morning Water Sleeping Mask from LANEIGE remains hard to beat. Those craving a stronger resurfacing kick can lean on T.L.C. Framboos Glycolic Night Serum by Drunk Elephant which pushes the AHA pedal further without sending skin into meltdown. Finally Advanced Night Restore by Medik8 is a great pick if you want peptides and ceramides working the graveyard shift to firm and replenish.
Before you slather on any of the above products let me slip into over-protective parent mode for a second: patch test first, keep sunscreen in daytime rotation and remember that results are only yours for as long as you stay consistent.
