Lactic Acid 70% vs Salicylic Acid 30%: Which Peel to Pick

Quick answer

If your skin is dry, tight, or sensitive and your main goal is smoother texture and a more even tone, choose the lactic acid 70% peel. If your skin is oily or congested and your main goal is visibly refined pores, choose the salicylic acid 30% peel. Both are professional-strength formulas for experienced users, so the deciding factor is your skin type and concern, not which acid is stronger.

What each acid does differently

Lactic acid is an AHA that works on the surface of the skin to help improve texture and support a more even-looking tone. The 70% strength is a professional-strength option, which means it is formulated for people who already have peel experience and understand how their skin responds to acids. It is often chosen when dryness or sensitivity makes stronger exfoliation uncomfortable.

Salicylic acid is a BHA that is oil-soluble, so it can work inside the pore rather than only on the surface. The 30% strength is a professional-strength exfoliating solution for experienced users, aimed at visibly refined pores and smoother-looking skin. That makes it a more targeted choice when congestion, blackheads, or oily texture are the main complaint.

Strength, format, and what the numbers mean

The percentage on the label tells you the concentration of the active acid, not how strong the peel will feel on your skin. A 70% lactic acid peel and a 30% salicylic acid peel are both professional-strength products, and neither is a beginner peel. The real difference is the acid family: AHAs like lactic acid are water-soluble and surface-focused, while BHAs like salicylic acid are oil-soluble and pore-focused.

Because these are high-concentration formulas, the rest of your routine matters as much as the peel itself. If you are already using retinoids, prescription acne treatments, or other exfoliating acids, adding either peel without adjusting your routine can overload your skin. The catalog does not list a neutralizer or full ingredient list for these products, so check the label and follow the manufacturer's instructions before use.

How to choose based on your skin type

Dry or sensitive skin usually tolerates lactic acid better because it is an AHA that supports smoother, softer-looking skin without the pore-focused action of a BHA. If your main issue is dullness, rough texture, or uneven tone rather than breakouts, the lactic acid 70% peel is the more logical starting point.

Oily or congested skin usually gets more from salicylic acid because its oil-soluble nature lets it target the pore lining. If you are dealing with visible blackheads, enlarged-looking pores, or persistent congestion, the salicylic acid 30% peel is the more direct match. If you have both dryness and congestion, you do not have to choose one forever, but you should not layer two professional-strength peels in the same session.

Timing and aftercare differences

Both peels require a recovery window, and the visible peeling that follows is part of the process rather than a sign something went wrong. With lactic acid, the focus after the peel is on rebuilding moisture, because dry skin can feel tighter during recovery. With salicylic acid, the focus is on keeping the skin calm and avoiding harsh scrubs while the pores clear.

In either case, pause other exfoliating acids and retinoids for several days after the peel, and use a gentle moisturizer and daily sunscreen. If you are unsure how your skin will react, test on a small area first and wait a few days before treating your full face.

Trade-offs at a glance

• Lactic acid 70%: better for dryness, less targeted for pores: Lactic acid is an AHA that supports smoother, softer-looking skin and a more even tone. It is the friendlier choice when dryness or sensitivity is your main issue, but it does not offer the same pore-focused action as a BHA. Choose this if texture and tone matter more to you than clogged pores.
• Salicylic acid 30%: better for congestion, potentially more drying: Salicylic acid is an oil-soluble BHA aimed at visibly refined pores and smoother-looking skin. It is more direct for oily, congested skin, but it can leave dry or sensitive skin feeling tighter during recovery. Choose this if visible pores and clogging are your primary concern.
• Both are professional-strength, so neither is a casual add-on: The 70% lactic acid and 30% salicylic acid peels are both formulated for experienced users. That means the trade-off is not which one is safer in general, but which one matches your skin type and how well you can commit to aftercare. If you are new to peels, start with a lower-strength option before either of these.
