Paulas Choice--SKIN PERFECTING 2% BHA Liquid Salicylic Acid Exfoliant--Facial Exfoliant for Blackheads, Enlarged Pores, Wrinkles & Fine Lines, 4 oz Bottle

Paula's Choice Skin Perfecting 2% BHA Liquid is a leave-on facial exfoliant formulated as a lightweight liquid rather than a scrub, so there are no abrasive particles involved. Salicylic acid, a beta hydroxy acid, is included at a 2% concentration. The liquid texture spreads easily across the face and neck and is left on the skin instead of being rinsed away. It comes in a 4 oz bottle and is formulated without added fragrance or parabens. The product sits within Paula's Choice's serum and exfoliant range, intended for regular use as part of a routine alongside cleansers and moisturisers.

• Active ingredient: 2% salicylic acid (BHA)
• Format: leave-on liquid exfoliant, non-abrasive, no scrub particles
• Size: 4 oz bottle
• Formulated without: fragrance, parabens

To use it, apply a small amount to a cotton pad and sweep it across cleansed, dry skin before applying any moisturiser or other leave-on products. Starting with a few times a week rather than daily allows skin to adjust to regular exfoliation. Avoid the eye area and rinse with water if any irritation occurs. Store the bottle at room temperature away from direct sunlight, and keep the cap tightly closed when not in use.

When comparing liquid exfoliants of this type, the key variables to weigh are concentration, pH level, and base formula, since these affect how the active ingredient performs. A leave-on liquid format is generally easier to apply consistently than a rinse-off version, and the 4 oz size offers enough product to gauge whether it suits your skin before committing to a smaller or larger size. This product is suited to those who prefer fragrance-free formulations and want to avoid physical scrubs. It works across skin types but may be particularly useful for those with oily or combination skin who are looking for a non-greasy exfoliating option.
