Exfoliant~€8typical, July 2026

Our read, in one look

Mandelic Acid is the reason to consider this exfoliant, with Glycerin behind it.

The case for it

  • Mandelic Acid, moderate evidence for oil and breakouts
  • Glycerin, strong evidence for hydration
  • No fragrance, alcohol, silicones or parabens

Mind this

  • Sunscreen the next day, acids leave skin more sun-sensitive
  • Add it on its own for a week or two, so you know what your skin is answering to
Best for dry, dehydrated, oily, acne prone skinFind it on amazon.com
Maya's read

The Ordinary Mandelic Acid 10% + HA is an exfoliant built around Glycerin, Mandelic Acid and Crosslinked sodium HA. It leans strongest on hydration, barrier repair, oil-control & blemishes. Best suited to dry, dehydrated and oily skin. Go slow: the active is potent enough to irritate if overused.

Skip it if your barrier is already sensitised or compromised: the acids can sting broken or over-exfoliated skin.

10 of the 13 sit above the 1% line. The other 3, hatched, are each under 1%. Widths show the ORDER on the label and nothing else: the label never discloses amounts, so we never draw them.

What's in it that matters

The molecule doing the workGlycerinHumectant · strong evidence

Classic humectant with strong evidence for improving skin hydration and supporting barrier when combined with emollients.

  • Mandelic AcidHero Activemoderate evidence

    Gentle AHA with larger molecular size that exfoliates, helps acne and pigmentation while being better tolerated than glycolic acid, especially on sensitive or darker skin.

  • Crosslinked sodium HAHumectantstrong evidence

    Crosslinked sodium hyaluronate that forms a hydrated gel matrix at the surface. Used in serums for longer lasting hydration that visibly softens fine lines while it is in place.

  • Pentylene GlycolHumectantmoderate evidence

    Short chain diol that works as a light humectant, co solvent and preservative booster. It keeps a formula less sticky and microbially stable while hydrating the outer layers.

How to use it

In the evening, and not every night: 2–3 times a week is plenty. Follow with a moisturiser, and wear sunscreen the next day.

Keep it away from

  • Retinoids (retinol, tretinoin)
  • Benzoyl peroxide
  • Other exfoliating acids the same night

Where it acts

The same cross-section as our 500 dalton page, with this formula's actives on the layer each one works on. Depth is the anatomy's, never an ingredient's.

4 of this product's actives have a layer we can defend.

Against the average exfoliant

HydrationBarrier repairBrighteningOil-controlAnti-aging
This productMedian exfoliant (6 in catalogue)

It scores higher than the median exfoliant on brightening.

On hydration, barrier repair and anti-aging it is level with the median, so that is not what sets it apart.

A median, not an average: one unusual formula should not move the middle. The numbers are the same 0 to 10 reads the comparison pages use.
