Paula’s Choice 2% BHA vs. Anua Heartleaf 77% vs. Glycolic 7%: Pore & Blackhead Toner Guide (2026)

Social media calls all three "pore-clearing miracle toners"—but one is an oil-soluble acid that dissolves blackheads, one is a water-soluble surface resurfacer, and one isn’t an acid at all.

1. Paula’s Choice 2% BHA: Why Only Salicylic Acid Dissolves Oil Plugs

Those tiny grey or tan dots across the bridge of your nose and chin are usually sebaceous filaments—natural tube-like linings that channel sebum to the surface. Water-based toners bounce right off oil, which is why splashing hydrating toners on your nose never clears them.

Paula’s Choice 2% BHA Liquid Exfoliant uses oil-soluble Salicylic Acid at an optimal pH of 3.2–3.8 paired with soothing methylpropanediol and green tea antioxidants. It slips inside the oil-filled pore lining, dissolves the oxidized sebum plug, and shrinks the appearance of stretched pores without gritty physical scrubs.

2. Anua Heartleaf 77% Soothing Toner: Why It Pairs With (Rather Than Replaces) BHA

Viral videos often pit Anua Heartleaf 77% against Paula’s Choice BHA, leading shoppers to think Heartleaf is an exfoliating acid. In reality, Anua Heartleaf 77% Soothing Toner is a pH 5.5–6.0 calming botanical essence rich in quercitrin flavonoids that reduce redness and regulate excess oil.

Because Anua contains zero exfoliating acids, you can actually layer Anua Heartleaf right after Paula’s Choice 2% BHA (or use BHA 3 nights a week and Anua every morning and evening) to keep your moisture barrier calm and bouncy.

3. The Ordinary 7% Glycolic Acid Toner & Acne Wash Pairings

Whereas Salicylic Acid (BHA) dives deep into oily pores, Glycolic Acid (AHA) has the smallest molecular weight of all alpha hydroxy acids and works on the outer surface to unglue dull, dead skin cells and fade hyperpigmentation. At $13 for a massive 8.0 oz (240ml) bottle, The Ordinary Glycolic Acid 7% Exfoliating Toner is one of the highest-value resurfacers in skincare—just remember never to layer it on the same night as BHA or Retinol.

Frequently Asked Questions

Can I layer Paula’s Choice 2% BHA and Anua Heartleaf 77% Toner together?

Yes! Apply Paula’s Choice 2% BHA first onto clean dry skin, wait 60 seconds, and then pat Anua Heartleaf 77% Soothing Toner on top to hydrate and soothe redness.

Can I use Paula’s Choice 2% BHA and The Ordinary 7% Glycolic Toner on the same night?

No. Stacking a leave-on BHA and a 7% AHA in the same routine over-exfoliates the stratum corneum. Alternate them on different evenings or use BHA on your oily T-zone only.
