Myth vs fact

Myth: Alpha arbutin whitens skin permanently.
Fact: No. It can slowly make dark spots look lighter, but it doesn't change your natural skin colour, and spots come back with sun exposure. Some regions set legal limits on its strength.

What it is

Arbutin is found in plants such as bearberry. Labels list Alpha-Arbutin or Arbutin (beta-arbutin). Deoxyarbutin is different; the EU safety committee (SCCS) did not find it safe.

What it does

It gently blocks tyrosinase, the enzyme that makes pigment, so fewer new spots may form. Results come slowly over months of regular use with sunscreen. It can release tiny traces of hydroquinone, which is why the EU sets a maximum strength for face products.

How to approach it

In a serum or cream, usually once or twice a day. Stronger isn't better; choose products made within the rules and follow their directions.

Morning or evening

Morning or evening both work. Without daytime sunscreen, no ingredient's results on spots will last.

If you're new to it

Start one new active at a time and give it at least two to four weeks before adding another. Patch test first: a little on the side of the jaw or behind the ear for a few days. Keep the rest of the routine simple: a gentle cleanser, a moisturiser and sunscreen by day.

Possible reactions

A few seconds of mild tingling or a little dryness can happen at first. Stop if burning doesn't settle, or if a red rash, itching, swelling or peeling keeps getting worse. Swelling of the face, lips or eyes, or trouble breathing, needs urgent medical care.

Questions people ask

Will it change my natural skin tone?

No, and that isn't the goal. It works on extra pigment such as sun spots or post-acne marks. Healthy skin isn't about being fair.

Tranexamic acid or alpha arbutin?

They work in different ways, and tranexamic acid has more melasma research. See our comparison guide.

Is it okay in pregnancy?

There's no pregnancy data, so be cautious, especially with stronger products. Ask your doctor.
