How do I apply it correctly, and how strong is the warming sensation?

The warming effect of this gel-balsam may be quite noticeable, so the sensible approach is to start small and build up only if you find the sensation comfortable.

1. Use a modest amount at first. A thin layer over the target area — knee, shoulder, lower back, neck, calf or forearm — is enough to judge how your skin responds. More product generally means more intense warmth, not better results.
2. Massage it in. The product is designed to be worked into the skin; the rubbing itself is part of the experience, so take a minute or two rather than just smearing it on.
3. Wash your hands thoroughly afterwards. This is essential with any warming gel — residue transferred to the eyes, nose, mouth or other sensitive areas is genuinely unpleasant. Avoid touching your face until your hands are clean.

A few practical points people often learn the hard way with warming products:

• Do not apply it to freshly shaved skin, right after a hot shower or sauna, or under tight occlusive clothing or bandages — all of these intensify the sensation considerably.
• Do not add external heat (heating pad, hot water bottle) on top of the treated area.
• If the warmth becomes uncomfortable, wipe off the excess with a dry cloth and then with an oil or greasy cream — plain water can briefly make the sensation feel stronger, not weaker.

Use it with particular caution on sensitive skin, and keep it away from mucous membranes and the eye area entirely.
