Serums & Oils: Frequently Asked Questions

What does a face serum do?

A face serum delivers a high concentration of active ingredients, like vitamin C, retinol or hyaluronic acid, deep into the skin to target specific concerns more powerfully than a moisturizer.

In what order do I apply serums?

Apply serums after cleansing and before moisturizer, from thinnest to thickest texture. A common approach is an antioxidant serum in the morning and a retinol or treatment serum at night.

Can I use more than one serum?

Yes, but layer thoughtfully. Water-based serums go before oil-based ones, and some actives like vitamin C and retinol are often split between morning and night to reduce irritation.

What is the best anti-aging serum?

For aging, vitamin C serums like SkinCeuticals C E Ferulic protect by day and retinol serums renew by night. Peptide and growth-factor serums add firmness. The best choice depends on your skin's tolerance and goals.

Are facial oils good for oily skin?

Certain lightweight, non-comedogenic oils can balance oily skin, but those prone to congestion often prefer gel serums. Patch-test and introduce oils gradually.

How long until a serum shows results?

Hydrating serums work immediately, while treatment serums like retinol and vitamin C typically show visible results over 8 to 12 weeks of consistent use.
