What solution is recommended for skin where a brace rubs?

Tincture of benzoin or alcohol is recommended for skin where a brace rubs because it acts as a protective barrier. This solution helps to prevent irritation and friction by creating a layer that enhances skin adhesion to the brace while also being antiseptic, which can reduce the risk of infection from any minor abrasions. Furthermore, the properties of tincture of benzoin allow it to promote healing in areas that are prone to chafing or contact dermatitis, making it suitable for individuals who need to wear braces regularly.

Using it in this context ensures that the skin is not only protected but also treated. In contrast, other options like water may not provide any protective barrier and could even worsen the irritation by not keeping the skin dry. Moisturizing lotion could improve skin hydration, but it may not be effective in preventing friction. Vaseline can provide lubrication but generally does not offer the protective and antiseptic benefits that tincture of benzoin possesses, making it less ideal for this specific circumstance.
