What should you know about Paula's Choice Boost?

A Boost product is a cosmetic formulation, while azelaic acid is a dermatology ingredient used for concerns such as clogged pores, blemishes, redness, and uneven pigmentation. It can support clearer-looking skin by helping normalize pore blockage and reducing inflammatory activity. Results depend on the formula, your skin barrier, and the concern being treated; a product cannot identify the cause of a rash or persistent discoloration.

Patch-test a small area before applying it more broadly. Introduce it on clean, dry skin at a frequency your skin tolerates, then use a plain moisturizer if dryness develops. Avoid layering it at first with several strong exfoliants, scrubs, or retinoids, because irritation can make redness or dark marks more noticeable. Daytime sunscreen helps limit pigment changes from ultraviolet exposure. For a medical overview, see Azelaic Acid and Azelaic Acid Treatment.

Stop using the product and seek prompt advice if you develop marked swelling, blistering, hives, breathing difficulty, or eye involvement. Arrange a dermatology assessment for painful deep spots, spreading redness, oozing, a rapidly changing dark patch, or symptoms that do not settle after removing likely irritants.

Ask whether azelaic acid matches your concern, whether another active ingredient could worsen irritation, and how to fit it around prescribed medicines. Mention pregnancy, eczema, a history of reactions, and every product used on the same area.
