Does chromium help with acne? What the research does and doesn't show

The evidence doesn't support chromium supplementation improving acne. The one trial that measured acne as an outcome — in adolescent girls with polycystic ovary syndrome taking chromium picolinate for 6 months — found no significant improvement in acne or hirsutism, even though other hormonal markers did shift. No trial of chromium was found for eczema, psoriasis, rosacea or other skin conditions.

What the evidence doesn't support

It doesn't support chromium supplementation as something that clears or reduces acne — the one controlled trial that tracked it directly found no improvement. It also doesn't cover any other skin condition: no trial testing chromium against eczema, psoriasis, rosacea or dermatitis was found in this literature, so this page can't speak to those.

What the trials found

A 2015 trial gave 35 adolescent girls (ages 14–17) with polycystic ovary syndrome 1,000 mcg/day of chromium picolinate for 6 months and re-evaluated them. Several PCOS-related markers improved: fewer had irregular or absent periods (from 83% to 31% of patients), ovarian volume and follicle count decreased, and free testosterone fell. But the study reported "no significant improvement in acne or hirsutism" — the two outward skin- and hair-related symptoms it tracked. This was a trial in adolescents with a diagnosed hormonal condition, managed by clinicians; this page doesn't offer dosing guidance for anyone under 18, and nothing here suggests a young person should take chromium on their own.

Some searches for "chromium and acne" surface a different product entirely: a topical 10% picolinic acid gel, tested in a small, open-label, uncontrolled 12-week pilot study of 15 people with mild-to-moderate acne, which reported reduced lesion counts. Picolinic acid is the acid that chromium picolinate is bound to — but this gel contained no chromium at all, was applied to the skin rather than swallowed, and had no placebo group to compare against. It doesn't tell us anything about an oral chromium supplement's effect on acne, and it's easy to mix the two up because of the shared word "picolinic/picolinate."

Questions people ask

Does chromium help with acne?

The one trial that measured it directly — in adolescents with PCOS — found no improvement. No other controlled trial testing chromium against acne was found in this literature.

Is chromium picolinate the same as the picolinic acid gel sometimes mentioned for acne?

No. Chromium picolinate is an oral mineral supplement; the picolinic acid gel tested for acne contained no chromium, was applied to the skin, and was studied without a placebo comparison. They share a name but aren't the same product or the same evidence.

Does chromium cause acne or breakouts?

No trial or safety review in this literature lists acne or breakouts as a reported effect of chromium supplementation.

Does chromium help with other skin conditions?

No trial testing chromium against eczema, psoriasis, rosacea or dermatitis was found — this page only covers what's actually been studied, which is acne, in one trial, with a null result.

When to talk to a doctor

Persistent or hormonal acne is worth discussing with a dermatologist or doctor, who can look at causes and options beyond what a supplement search will turn up. Chromium is not a treatment for acne or any other skin condition, and the one trial that measured it found no benefit. This page doesn't cover dosing for anyone under 18 — talk to a pediatrician before giving any supplement to a teenager or child.
