Salicylic acid in the treatment of acne and psoriasis

We regularly receive enquiries about salicylic acid and why it’s included in many topical skincare and scalp formulations. For some people, off-the-shelf options are suitable. For others, skin may be more sensitive, the application area may be difficult, or a clinician may prefer a customised strength and base.

That’s where a compounding pharmacist can help — by preparing a salicylic acid formulation tailored to the intended use, skin type, and application preferences, where appropriate.

What is salicylic acid?

Salicylic acid is a beta-hydroxy acid (BHA) commonly used in topical formulations to help soften and lift dead skin cells and support gentle exfoliation. Because of this, it’s widely found in products designed to support clearer-looking skin and smoother texture.

Why compounding can be useful

Compounding can be considered when a prescriber or patient needs something that isn’t available commercially, such as:

• a specific concentration (e.g., when standard retail options aren’t suitable)
• a different base (cream, ointment, gel, lotion) to suit sensitive skin or specific body sites
• fragrance-free or simplified ingredient options (where possible)
• a specific pack size or application format

At National Custom Compounding (NCC), our pharmacists can discuss whether a compounded option is appropriate and what strength/base may be most suitable — and we’ll recommend medical advice when needed.

Common areas salicylic acid may be used in topical care

Depending on individual circumstances and professional advice, salicylic acid is commonly included in formulations designed to support management of:

• rough, thickened, or flaky skin
• calluses and corns
• scalp flaking
• areas of hard or thickened skin (e.g., elbows, knees, heels)

Note: suitability depends on the person, the body site, and the overall skincare plan.

Strength and safety considerations

Salicylic acid can be irritating and is not suitable for everyone. Higher strengths are not automatically “better” and may increase the risk of dryness, redness, or irritation — particularly on facial skin or sensitive areas.

A pharmacist can help you understand:

• appropriate strength ranges for the intended area
• how to use the product safely (frequency, application amount, and duration)
• when to stop and seek medical advice

Do I need a prescription?

This depends on the final formulation and the individual circumstances. While salicylic acid itself may be available in non-prescription products, compounded preparations involve pharmacist assessment, and in some situations a prescription may be recommended or required.

If you’re unsure, our team can guide you on the best next step.
