It is completely fine to apply essence at night. Some essences with whitening effects will even state that it is best to use them at night. This type of essence contains antioxidant ingredients and will not react with ultraviolet rays when used at night, making the whitening effect better.

Serums containing photosensitive ingredients can only be used at night

Some essences contain natural plant extracts, such as essential oils from citrus plants, grapefruit, bitter orange, sweet orange, tangerine, lemon, lime, etc. These ingredients will increase the skin's sensitivity to light. After application, you should try to avoid direct exposure to sunlight. Therefore, it is best to use this type of essence at night. Kiehl's Night Repair Serum contains plant essential oils that are antibacterial, anti-inflammatory and skin-repairing, so it is not suitable for application during the day when ultraviolet rays are strong. Goddesses should just apply it before going to bed.

It is also best to use serum containing retinoic acid at night.

Vitamin A acid (retinoic acid) has anti-aging effects, but it has certain side effects. One of these side effects is that it increases the photosensitivity of the skin. Therefore, serums containing retinoic acid are best used at night. Olay Professional Formula Anti-Wrinkle Essence and Estee Lauder ANR Essence are representatives of this type of essence.
