If you want to address a particular concern, choose a targeted treatment rather than adding every category. If you prefer fewer steps, choose one of these products and keep cleanser, moisturizer and morning sunscreen in place.12

How do you fit them into your routine?

  1. 1Wash with a gentle cleanser and gently pat dry.
  2. 2Apply any skin medication or prescribed treatment directly after cleansing, rather than letting optional cosmetic layers take its place.
  3. 3If you use toner, apply it before essence. In the fuller Korean routine, essence comes before an ampoule or serum.
  4. 4Apply moisturizer after your treatment products, and finish with sunscreen in the morning.

An essence or ampoule can fit into a morning or evening routine. Introduce new products slowly instead of starting several together, so you can identify which product helps and which causes trouble.1

Is ampoule the same as serum?

For routine planning, an ampoule and a serum are alternatives in the same targeted treatment slot, not two compulsory steps. The routine does not need a second chair just because the bottle has a different name.1

Should you use ampoule or serum first?

If you use both, follow the general layering rule: thinnest to thickest, rather than deciding by the product names. Apply the lighter product first and the thicker one afterward, before moisturizer. This is general layering guidance, not a reason to add another treatment.2

Can you use an ampoule and serum together?

Do not assume two treatments belong together just because their names differ. A simpler starting point is one targeted product: using more products increases the chance of side effects, and multiple products aimed at signs of aging can irritate skin.23

If your skin is sensitive, patch test a new product on your inner arm before applying it to your face. Be particularly careful with fragrance and preservatives. If a product leaves your face tight or dry, choose something else. Stop using a product that causes irritation and make an appointment with a dermatologist.12
