A Finnish dermatologist, Ari Karppinen, emphasizes the importance of moisturization immediately after bathing in a sauna or shower. He introduces the 'three-minute rule,' which states that applying moisturizer within three minutes post-wash can help maintain skin hydration, prevent dryness, and improve overall skin condition. This advice is especially pertinent for individuals who frequently engage in sauna therapy, as the heat and sweating can strip away moisture from the skin.

In addition to general skin care, podiatrists recommend regular moisturizing of the feet to combat dryness and the formation of calluses. By applying lotion or cream routinely and in small amounts, individuals can achieve better skin health compared to harsher methods like scraping or cutting calluses. This practical advice indicates that when skin is kept in optimal condition, the benefits of sauna usage—such as improved blood circulation and toxin elimination through sweating—can be fully realized.

While not all users feel motivated to moisturize immediately after bathing due to the feeling of already greasy skin, experts clarify that trialing the practice can yield beneficial results for those with dry or tight skin. If a medicated cream is being used, it is prudent to apply it after sauna sessions, highlighting the importance of post-bathing skin care routines for optimal skin maintenance.
