What is actually different?

This comparison covers The Ordinary's US Salicylic Acid 2% Solution, not its masque or another formula. The exact Paula's Choice BHA product is needed to compare strength, ingredients, texture, directions and price accurately.3

Choose The Ordinary if you want a salicylic acid serum specifically intended for blackheads, with clear instructions for treating the affected area. There is no sound reason to choose Paula's Choice solely because of its name, or to assume The Ordinary is weaker. Choose by the active ingredient, not the logo, which has no job inside a pore.1

What can salicylic acid do for blackheads?

Blackheads are small plugs at the openings of pores, also called open comedones. Salicylic acid can help treat them by unclogging pores and removing dead skin. The dark dots are not dirt, so blackhead treatment is not a cleanliness competition. Scrubbing can worsen acne.45

Salicylic acid is a reasonable option, not the strongest established acne treatment. Its clinical recommendation is conditional because evidence of benefit is limited. For stubborn blackheads, retinoids are another treatment option; they help clear blocked pores and are cornerstone acne treatments.6

How should you use The Ordinary?

  1. 1Patch test first. Apply as directed to a small area once daily for three days to check for sensitivity.
  2. 2Cleanse gently before applying. The Ordinary includes Salicylic Acid 2% Solution in its evening routine.
  3. 3Apply a thin layer across the entire affected area, not only individual visible blackheads. Start once daily.
  4. 4Apply moisturizer afterwards. Do not add the second BHA or another exfoliating acid to the same routine.
  5. 5Use broad spectrum sunscreen daily. If bothersome dryness or peeling develops, reduce application to once daily or every other day.

The US label allows a gradual increase to two or three applications daily if needed or directed by a doctor. That is an upper frequency, not a starting target. Excessive product does not necessarily speed results and can cause dryness, redness or irritation.23

How long should you give it?

Give one acne treatment six to eight weeks of consistent use before judging it, without adding another acne treatment during that trial. General acne treatment timelines are fewer breakouts in four to eight weeks and clearing around sixteen weeks when treatment works. These are not product specific deadlines for either brand.1

Who should be careful or get help?

Another topical acne medication increases the likelihood of irritation and dryness with The Ordinary's solution. If irritation occurs, use only one topical acne medication at a time. Rinse off, stop use and consult a doctor right away for irritation, hives, swelling of the eyes or mouth, blistering or difficulty breathing.3

If you are pregnant or trying to become pregnant, consult a dermatologist before treating acne yourself. Seek treatment for deep painful pimples or scarring. If blackheads persist after six to eight weeks, a dermatologist can consider extraction or prescription treatment rather than another bottle swap.15
