What action should be taken after exfoliation in skin treatments?

After exfoliation in skin treatments, using sunscreen is essential for several reasons. Exfoliation removes dead skin cells and can leave the skin more sensitive and prone to sun damage. This increased fragility means that the skin has a higher risk of UV damage, so applying sunscreen provides a protective barrier against harmful rays. It helps maintain the health of the newly revealed skin and prevents potential irritation or long-term damage from sun exposure.

Applying heavy moisturizer, performing deep tissue massage, or using a face mask might have their own benefits in specific contexts, but they do not address the immediate need to protect the skin post-exfoliation. The priority after exposing the freshly exfoliated skin is to shield it from external aggressors, making sunscreen the most appropriate choice in this scenario.
