What actually changes between cream and oil?

Compare the actual products before buying, because 'cream versus oil' leaves most of the label out of the argument. Retinol percentages are not always disclosed on packaging, so the format name cannot tell you the strength.1

The base can affect how retinol travels through a barrier. In an artificial membrane experiment, adding jojoba oil to a retinol emulsion increased retinol passage. Whether that translates into better visible results or better tolerance on people's faces remains unsettled. Choose a cream if its directions and strength suit your routine; choose an oil on the same basis, not for an assumed performance advantage.3

How should you start using either?

  1. 1Test a small amount on a small area first. Wait a couple of days and check for redness or itching before using it more widely.
  2. 2At bedtime, gently cleanse and pat your skin dry. Do not scrub.
  3. 3Apply according to the package directions, avoiding your eyes, mouth and nose. General retinol guidance uses a thin, pea sized amount, but check the application quantity for an oil.
  4. 4Begin every other night and increase gradually only as your skin tolerates it.
  5. 5Finish with moisturizer. During the day, use sunscreen, seek shade and cover exposed skin.

Keep a separate moisturizer in the routine rather than asking the retinol product to hold two job titles.2

What should you expect?

Visible improvement takes several weeks; changes in fine lines usually take several months. Early effects can include dryness, redness, peeling, itching or burning. Retinol can improve uneven tone and texture, but irritation deserves attention rather than being treated as proof of progress.12

Who should be careful?

Do not use retinol during pregnancy. If your skin is already very dry, allergy prone, red or inflamed, ask a dermatologist about alternatives before starting either format. Irritation can trigger dark marks in darker skin, making a slow introduction and moisturizer especially useful.1
