How should I apply this gel for the best effect on my knees?

Squeeze a small amount onto fingertips and spread it evenly over the knee area and the surrounding skin — front, sides, and just above and below the joint. Use gentle circular motions with the palms or fingertips for about two to three minutes; the massage itself generates warmth and helps the gel form a smooth, non-greasy layer. The gel texture is designed to spread easily without the heaviness of an ointment, so a thin layer is sufficient. Most people apply it once in the evening after a day of walking, standing, or exercise, and optionally a second time in the morning if stiffness is noticeable. Do not apply to broken, irritated, or freshly shaved skin, and wash hands after use. Because the formula contains camphor, you will feel a warming, slightly tingling sensation — this is normal and usually fades within 10–15 minutes. If the warmth feels excessive, rinse the area with cool water and discontinue use.
