Guide to Choosing Deodorant and Antiperspirant

In our hot climate, choosing deodorant is an important daily decision. Many people do not realise that deodorant and antiperspirant perform different functions.

The Difference Between Deodorant and Antiperspirant

Sweat itself is almost odourless. Odour develops when bacteria on the skin break it down. Deodorant addresses odour only, using ingredients that limit bacteria, absorb odour or mask it with fragrance; it does not reduce sweat volume. Antiperspirant contains aluminium salts that temporarily plug sweat-gland openings, reducing sweat. Many products combine both functions, so read the label and look for antiperspirant if wetness, rather than odour, is your concern.

Available Formats

  • Roll-On: a liquid offering precise coverage that needs a minute to dry.
  • Stick: solid and portable, suitable for those preferring quick drying.
  • Spray: quick and lightweight; spray from a distance and avoid inhalation.
  • Cream: a small amount is enough, suitable for those wanting control over the quantity.

Options by Need

Daily Sweat and Clothing

For Sensitive Skin

Choose fragrance-free or alcohol-free formulas, and avoid applying any product to irritated or broken skin.

Options Without Aluminium Salts

These suit those who want odour control without reducing sweat and are deodorants in the precise sense.

Products Labelled for Lightening

Underarm darkening often relates to friction or irritation from shaving or hair removal, so gentle hair-removal methods and loose cotton clothing can help alongside the product.

If thick, velvety darkening appears suddenly in the underarms or neck, it may signal a condition needing medical assessment, such as acanthosis nigricans, sometimes associated with insulin resistance. See a doctor.

How to Use Correctly

  • Apply antiperspirant at night to clean, completely dry skin. Sweat glands are less active then, allowing the product to absorb well and its effect to last into the next day.
  • Deodorant may be added in the morning for freshness.
  • Wait after shaving, and do not apply to broken or irritated skin unless the product is intended for this.
  • Allow the product to dry before dressing to reduce stains.

Common Mistakes

  • Expecting deodorant alone to prevent wetness.
  • Applying to wet skin immediately after showering.
  • Continuing a product that causes itching or redness.

Consult a doctor if sweating is heavy enough to affect daily life, appears suddenly or occurs during sleep without a clear cause; medical options for excessive sweating are available. Ask the pharmacist if you have questions about a product's suitability for your skin.
