Tretinoin vs tazarotene: how do the two retinoids compare?

Approved uses · Directions · Pregnancy · Head-to-head trials

Short answer: Both are prescription retinoids for acne used once in the evening, but tazarotene (Tazorac) is also approved for psoriasis and is not allowed in pregnancy.12 In a 12-week trial of 143 people, tazarotene 0.1% gel cleared non-inflamed spots better than tretinoin 0.025% gel.3 A later trial of other strengths found results generally similar.4

How do tretinoin and tazarotene compare side by side?

What did the head-to-head trials find?

  • Webster 2001: a double-blind trial randomized 143 people with mild to moderate facial acne to tazarotene 0.1% gel or tretinoin 0.025% gel once a day for 12 weeks. Tazarotene reduced open comedones (blackheads) and total non-inflamed spots more; the drop in inflamed spots was not significantly different. Tazarotene caused more irritation at some time points, but it stayed at trace levels.3
  • Kircik 2009: a single-center, investigator-blinded 12-week trial compared tretinoin 0.04% microsphere gel with tazarotene 0.05% cream. Results were generally similar, with faster early improvement and less dryness and peeling on the tretinoin gel.4

The trials used different strengths and forms, so neither settles which retinoid suits a given person.

Why are the pregnancy rules different?

The Tazorac label says tazarotene can harm a fetus and is contraindicated in pregnancy. Women who could become pregnant need a negative pregnancy test within 2 weeks before starting and effective birth control during treatment.2 The Retin-A label says tretinoin should be used in pregnancy only if the benefit justifies the risk.1

What do both labels warn about?

  • Sun: both say to limit sun and sunlamps and not to use them on sunburned skin.12
  • More is not better: the Retin-A label says applying more gives no faster or better results, only more redness and peeling.1
  • Eczema: the Tazorac label says not to use it on eczema, where it can cause severe irritation.2
