AHA body lotion softens dry, rough texture while BHA treatments target clogged pores and bumps. Compare Paula's Choice options to pick the right chemical exfoliant for your body.

Quick answer

For overall dry, rough texture and dullness, choose an AHA body lotion like Skin Revealing Body Lotion 10% AHA because it exfoliates and moisturizes in one step. For hard, clogged bumps or enlarged pores on arms and legs, a BHA treatment such as BHA 9 Treatment is the better fit since salicylic acid targets oil and pore blockages. Many people can use both, alternating days or body zones.

How AHA and BHA differ on body skin

Alpha hydroxy acids (AHAs) are water-soluble and work on the skin's surface to loosen dead cells, making them ideal for diffuse roughness, dryness, and sun damage. Beta hydroxy acid (BHA), specifically salicylic acid, is oil-soluble, so it can penetrate into pores and dissolve the debris that causes clogged bumps and rough patches. On the body, this means AHAs generally improve texture and hydration, while BHAs address pore-related concerns like hard white bumps or milia-prone areas.

AHA body lotion: moisture plus surface renewal

Skin Revealing Body Lotion 10% AHA is a leave-on exfoliant that gently removes built-up dead skin while delivering creamy moisture. It significantly improves the appearance of hard, clogged, red bumps on arms and legs, and leaves skin feeling soft and hydrated. Because it's a lotion, it suits daily use on larger areas like legs, arms, and back. If your main complaint is dry, flaky, or crepey texture, this is a straightforward one-step option.

BHA treatment: targeted pore clearing

BHA 9 Treatment is a concentrated leave-on exfoliant with salicylic acid that delivers controlled, sustained release. It minimizes the appearance of enlarged pores and diminishes hard white bumps, and it's suitable even for skin prone to milia. This is a spot-treatment or targeted product rather than an all-over lotion. If you have oily or bumpy skin on your back, chest, or upper arms, a BHA can reach where a surface AHA cannot.

Can you use both?

Yes, but introduce them carefully. A practical approach is to use an AHA body lotion on most days for overall texture and hydration, and apply a BHA treatment a few times a week to specific bumpy or congested areas. Avoid layering both on the same skin at the same time, especially if you're new to chemical exfoliants. Always use sun protection on exposed skin, as AHAs can increase sun sensitivity.

Trade-offs to weigh

AHA body lotion: all-over convenience vs. surface-level action: Skin Revealing Body Lotion 10% AHA exfoliates and moisturizes in one step, but it works mainly on the surface, so it may not clear deep pore blockages. Best if your main issue is dry, rough texture rather than stubborn bumps.
BHA treatment: pore-clearing power vs. targeted use: BHA 9 Treatment penetrates pores to minimize enlarged pores and hard white bumps, but it is a concentrated leave-on product meant for specific areas, not all-over daily use. Best for oily, bumpy, or milia-prone zones on the body.
Retinol body treatment: anti-aging vs. exfoliation: Retinol Skin-Smoothing Body Treatment improves uneven tone and firmness, but it does not exfoliate like an AHA or BHA and requires careful sun protection. Consider it as an add-on for tone and firmness, not a substitute for exfoliation.

Key product facts

It’s suitable even for skin prone to milia. Delivers controlled, sustained release of salicylic acid. It targets pore-related bumps and rough patches that AHAs may not fully resolve, especially on oily or milia-prone areas.

Which should you choose?

Choose AHA body lotion if

You have dry, rough, or flaky skin on arms, legs, or back and want one step that exfoliates and moisturizes.
Your main concern is overall texture and dullness, not specific clogged pores or bumps.

Choose BHA treatment instead if

You have hard, clogged bumps, enlarged pores, or milia-prone skin on your body.
Your skin is oily or prone to congestion and you need a targeted exfoliant that reaches inside pores.
