Steps

  1. Wash your face and look at it in good light. Write down your single biggest concern: breakouts, dark spots, oiliness, dryness or fine lines.

  2. Match that concern to an ingredient. Acne and clogged pores point to salicylic acid. Oily skin points to niacinamide.

  3. For dark spots and uneven tone, look at vitamin C, alpha arbutin or kojic acid. For tight, dehydrated skin, choose hyaluronic acid or panthenol.

  4. For fine lines and sun damage, consider retinol. Start with a low strength and use it only at night.

  5. Buy just one serum for now. Check the label for the ingredient name and its percentage so you know what you are using.

  6. Patch test first. Apply a small drop behind your ear or on your inner arm and wait 24 hours for any redness or itching.

  7. Add the serum to your routine slowly, two or three nights a week at first. Apply it to clean, dry skin before moisturiser.

  8. Build up to daily use if your skin stays calm. Keep the rest of your routine simple: cleanser, moisturiser and sunscreen.

Tips and common mistakes

Do not start several new serums in the same week, or you will not know which one caused a reaction.

Vitamin C and retinol can irritate together, so use vitamin C in the morning and retinol at night.

Sunscreen is essential when using acids or retinol, since skin becomes more sun sensitive.

Stop using a serum and see a doctor if you get swelling, severe redness or a rash.

Questions

How many serums should I use at once?

One or two is plenty for most people. Pick a serum for your main concern first, then add a second only after a few weeks if your skin is happy.

Can I use niacinamide with vitamin C?

Yes, most modern formulas are fine together. If your skin stings, apply them at different times of day.

When will I see results?

Give a new serum four to six weeks of regular use before judging it. Dark spots and fine lines often take longer.
