Serum

Facial serums deliver concentrated ingredients deep into the surface layers to support everyday skin health, radiance, and moisture. These versatile formulas suit most skin types and come in lightweight liquids, gels, and oils. Because they layer easily, you can apply them smoothly beneath your favorite daily moisturizer and sunscreen.

Questions and answers

What does serum do for the skin?

Serum helps deliver active ingredients directly into the skin to target specific concerns like hydration or aging. It is typically applied daily before heavier creams to boost your skincare routine.

How do you use serum?

Apply serum to clean skin once or twice a day before your moisturizer. It helps deliver active ingredients deeply into the skin to target specific concerns.

Should you use serum in the morning or at night?

You can use serum in both the morning and at night depending on the specific formula and your skincare goals. Using them at different times helps target various needs throughout the day.

Can you use serum every day?

Yes, you can use serum every day depending on the specific formula and your skin's needs. Many hydrating or soothing serums are gentle enough for daily morning and evening use.

Does serum cause purging or irritation?
