Detailed answer

While some serums may offer minimal sun protection, they are typically not sufficient to provide adequate protection against the harmful effects of the sun's ultraviolet (UV) rays. It is recommended to use a separate sunscreen in addition to your serum. Sunscreens are specifically formulated to shield your skin from UV radiation and help prevent sunburn, skin damage, and premature aging. Look for broad-spectrum sunscreens with an SPF of 30 or higher for optimal protection. Apply the serum first, allowing it to fully absorb into the skin, and then apply the sunscreen as the last step in your skincare routine.
