What safety measure helps prevent chemical burns from pigments or anesthetics?

• A. Patch test prior to full application; follow manufacturer directions for dilution and application times.
• B. Increase pigment concentration to ensure quicker results.
• C. Patch testing is optional.
• D. Rely on client history alone.

Answer: (A)

Preventing chemical burns from pigments or anesthetics starts with testing skin compatibility before proceeding with the full treatment. A patch test uses a small amount of the product applied to a discreet area and left for the time recommended by the product instructions. After the designated period, you look for signs of a reaction—redness, itching, swelling, or irritation. If any reaction occurs, you avoid using that product on the client. This step catches sensitivities to pigment ingredients, preservatives, metals, or anesthetic agents that the client might not disclose or even know about.

Following the manufacturer’s directions for dilution and how long the product stays on the skin is essential. Improper dilution can make products more caustic or irritating, and leaving a product on the skin too long can increase burn risk. Together, patch testing and proper dilution/application times form a safety check that minimizes the chance of chemical burns during the actual procedure.

Relying on client history alone isn’t enough because not all sensitivities are known or reported, and reactions can develop over time. Patch testing provides a practical, proactive safeguard to protect the client.
