Azelaic acid or retinol for uneven texture?

What kind of unevenness are you treating?

Whiteheads are small skin coloured bumps; inflamed acne spots are another source of raised texture. Acne can also leave changes in colour and scars. A brown mark after a spot is a colour problem, not a bump, even if both get filed under the impressively vague word "texture". The useful comparison is bumps versus roughness versus marks, not which bottle has the more ambitious adjective.3

Retinol is not the same treatment as prescription tretinoin or the acne retinoid adapalene. If clogged pores and ongoing acne are your main concern, those acne treatments deserve a separate discussion rather than assuming a cosmetic retinol is interchangeable. Cream versus gel also matters when following directions: azelaic acid formulations have different approved uses.15

How should you start?

For retinol, choose the lowest strength available and begin every other night, increasing slowly as tolerated. Use moisturiser to help limit irritation. During the day, apply sunscreen to exposed skin and use shade and protective clothing. If you already use a prescription retinoid, follow its directions rather than applying this cosmetic starting schedule.1

For prescribed azelaic acid gel or cream:

1. 1Wash the affected area with a mild cleanser and pat dry.
2. 2Apply a thin layer to affected skin and gently massage it in. Keep it out of your eyes and mouth.
3. 3Wash your hands after application. Apply makeup once the medication is dry.

Prescription azelaic acid is usually used morning and evening. Follow the prescription label rather than increasing the amount or frequency yourself. If you miss a dose and the next one is nearly due, skip the missed dose; do not double up. Tell your prescriber about other medicines and skincare treatments you use.5

How long should you give it?

Azelaic acid cream can begin improving acne after about a month, with further improvement and maximum results after six months of continuous use. Rosacea can take up to 12 weeks to start improving. If acne has not responded after two months, arrange a treatment review. There is no single reliable retinol texture timeline to give here.24

Who should be careful?

Avoid retinoids during pregnancy; prescribed topical retinoids should also be avoided during breastfeeding. Retinoids are a poor starting choice for very dry, allergy prone or markedly red and inflamed skin. Irritation can trigger dark marks in darker skin tones, making a slow start especially useful.16

Azelaic acid can irritate very sensitive skin or eczema. Stop and seek medical advice for severe redness, scaling, itching or burning. Discuss pregnancy or breastfeeding with your prescriber before using it, and report skin colour changes or worsening asthma. Stop using azelaic acid and seek emergency care for difficulty breathing or swelling of the face or throat.25

See a doctor if the unevenness includes deep, painful spots, scarring, or acne that is not improving with treatment. Moderate or severe acne scarring needs assessment before trying a retinoid. Avoid scrubbing acne bumps or picking spots: scrubbing can worsen irritation, and picking can cause scars.13
