Final answer:
It is generally recommended to avoid applying SPF after a facial treatment performed in the evening. Instead, focus on using alcohol-free products and avoiding any products that can irritate the skin.
Step-by-step explanation:
When it comes to applying SPF after a facial treatment performed in the evening, it is generally recommended to avoid doing so. This is because most SPF products are designed to provide protection against the sun's harmful UV rays during the day, and they may not be as effective if applied in the evening.
Additionally, applying SPF at the end of a facial treatment could potentially interfere with the absorption and efficacy of other skincare products that were applied during the treatment.
Instead, it is important to focus on using alcohol-free products and avoiding any skincare products that can irritate the skin, such as harsh astringents or exfoliants. Rinsing with lukewarm water is also recommended, while avoiding using very hot or cold water.
