Neostrata Enlighten 15% Vitamin C + PHA Serum is what Neostrata calls its new gold standard in vitamin C: 15% pure L-ascorbic acid paired with 2% gluconolactone, a polyhydroxy acid that gently exfoliates so the vitamin C absorbs into renewed surface layers. With feverfew and green tea making four antioxidants in every drop, it is the brightening vitamin C serum for dark spots, fine lines and dull skin, shown to look brighter in one week.

Neostrata chose pure L-ascorbic acid over derivatives for its effectiveness; it brightens the appearance of discolouration and helps visibly fade dark spots and dark patches. The 2% PHA exfoliates gently without sun sensitivity, while 1% feverfew and green tea EGCG boost antioxidant capacity against environmental aggressors. Neostrata's consumer-study results are striking: skin looked instantly glowing for 100%, 98% saw brighter skin after one week, 93% saw fine lines less visible at four weeks, and after 12 weeks 95% said their complexion was dramatically brighter and 93% that tone was dramatically more even. Neostrata Enlighten 15% Vitamin C + PHA Serum is fragrance free, paraben free, and dermatologist and allergy tested.

Choose Neostrata Enlighten 15% Vitamin C + PHA Serum if you want pure, high-strength vitamin C as your morning brightening step; for a gentler, acid-free brightener, Enlighten Illuminating Serum is the alternative.

Becci has worked as a registered aesthetics nurse for over 20 years in specialist skincare and medical aesthetics, and she is honest with clients that pure vitamin C serums vary wildly in quality. Neostrata Enlighten 15% Vitamin C + PHA Serum is one she recommends because Neostrata has thought through the usual problems: PHA exfoliation so the vitamin C reaches the skin, no fragrance, and a 15ml bottle sized to be used up while the L-ascorbic acid is fresh.

Size: 15ml

FAQS

Is Neostrata Enlighten 15% Vitamin C + PHA Serum good for dark spots? +

Yes. Neostrata describes the 15% pure vitamin C as brightening the appearance of discolouration and helping to visibly fade dark spots and dark patches, and in the brand's study 93% said tone was dramatically more even after 12 weeks of once-daily use. Daily SPF is essential alongside it.

Does Neostrata Enlighten 15% Vitamin C + PHA Serum replace the Illuminating Serum? +

Neostrata's UK site states that it replaces the now discontinued Illuminating Serum. They are different formulas: this is a pure L-ascorbic acid serum with 2% PHA for morning use, whereas the Illuminating Serum is a niacinamide and NeoGlucosamine serum used morning and evening. We continue to stock the Illuminating Serum while it remains available.

Can I use Neostrata Enlighten 15% Vitamin C + PHA Serum with retinol? +

Yes - keep them to separate ends of the day. Vitamin C in the morning under sunscreen, retinol or Enlighten Pigment Controller in the evening. That is how Neostrata itself pairs the Enlighten day and night serums.

Why has the serum changed colour? +

Pure L-ascorbic acid naturally deepens in colour over time. Neostrata states the product colour may change but it remains effective; storing it upright in a cool, dark place slows the change.

Will 15% vitamin C sting or irritate my skin? +

A brief tingle on application is common with pure vitamin C and usually settles within a minute. The formula is fragrance free, paraben free, and dermatologist and allergy tested, and the PHA is chosen for gentleness. Patch test first and start every other morning if your skin is reactive.

What is PHA and why is it in a vitamin C serum? +

PHA stands for polyhydroxy acid - here 2% gluconolactone, which Neostrata pioneered. It exfoliates the surface gently and without sun sensitivity, so the vitamin C absorbs into fresh, renewed skin rather than sitting on dead surface cells.

How quickly will I see results? +

In Neostrata's study 100% said skin looked instantly glowing, 98% saw brighter skin after one week, 93% saw fine lines less visible at four weeks and 95% said their complexion was dramatically brighter at 12 weeks.

How should I store it and how long does the bottle last? +

Upright, in a cool, dark place, and open it carefully as the contents may be under pressure. At two drops every morning, the 15ml bottle lasts around two to three months - about right for a pure vitamin C to stay fresh.

Can I use Neostrata Enlighten 15% Vitamin C + PHA Serum during pregnancy or while breastfeeding? +

It contains no vitamin A. Neostrata states there are no known safety concerns with using its cosmetic products during pregnancy but recommends that anyone pregnant or breastfeeding seeks their doctor's advice. Products of this kind are generally considered suitable, but run the ingredient list past your midwife or GP before adding it to your routine.
