I have sensitive skin — how should I test this before using it on larger areas?

If you know your skin reacts to strong cosmetics, start with a pea-sized amount on the inner forearm or just behind the knee — areas with thinner skin but not mucous membranes. Wait 10–15 minutes. A mild tingling or cool flush is normal; burning, stinging that increases, redness that spreads, or itching means this formula isn't right for you. The menthol and camphor concentrations in horse balms are typically high enough to irritate very sensitive or atopic skin, especially if the barrier is already compromised (recent shaving, sunburn, eczema flare). Avoid applying on broken skin, fresh wounds, rashes, or anywhere near the eyes, lips, and genital area. If the test patch feels fine, you can use it on larger zones like calves, thighs, lower back, or shoulders. Wash hands after each application so you don't accidentally transfer product to your face or eyes.
