How Often Should You Use Each Serum? A Simple Frequency Guide for All 6 Tommy FX Serums

By Admin ·

Most skincare mistakes aren't about buying the wrong serum. They're about frequency — using a strong serum every day from day one, or using a gentle one so rarely it never gets a chance to work. The rule for every Tommy FX serum is the same amount — 2–3 drops on clean skin, moisturiser on top, SPF every morning — but how often is different for each one. Here is the simple version, for all six.

The cheat sheet

Serum

When

How often

Bright Glow Elixir (Skin Whitening) — dark spots & glow

Morning + night

Twice daily

White Rice Serum — acne marks & glass skin

Morning + night

Twice daily

Vitamin C 20% — dullness & tan

Morning

Your morning brightness step

Niacinamide 10% + Zinc — pores, oil & redness

Morning + night

Twice daily

Hyaluronic Acid 2% — dry, tight skin

Morning + night, on slightly damp skin

Twice daily

Retinol 0.5% — fine lines & texture

Night only — never in the day

Start slow (see below)

Retinol is the only slow start

Retinol 0.5% is beginner-friendly, but it still earns a slow start — this is the one serum where "more, sooner" backfires:

  • Weeks 1–2: 2–3 nights a week
  • Weeks 3–4: every other night
  • Then: every night, if your skin is comfortable

Always at night, 2–3 drops, moisturiser on top, and SPF the next morning without fail. Patch-test first if your skin has reacted to products before. The honest timeline is 8–12 weeks — brightness first, then texture.

Don't use all six at once

Six serums does not mean a six-serum routine. Pick by your #1 concern and start with one or two:

  • Acne marks / glass skin → White Rice
  • Dark spots, dullness, tan → Vitamin C 20% or Bright Glow Elixir
  • Open pores / oily skin → Niacinamide 10% + Zinc
  • Dry, tight skin → Hyaluronic Acid 2% on damp skin
  • Fine lines / texture → Retinol 0.5% at night

Add a second serum only once the first feels settled in your routine. Consistency with one serum beats a crowded shelf every time.

Layering order in 30 seconds

Thinnest first, one after the other — never mixed together in your palm. Hyaluronic Acid goes on slightly damp skin first for hydration, then your treatment serum, then moisturiser to lock it in, then SPF in the morning. Vitamin C is a morning step, Retinol is a night step — split them AM/PM, never at the same time.

What to expect, and when

Hydration is the fastest change to feel. Tone starts looking more even in about two weeks of steady use. Acne marks and dark spots fade over weeks, not overnight — the same steady-routine story as the testimonials on tommyfx.pk. Retinol's full timeline is 8–12 weeks. If nothing seems to change in the first few days, that is normal; serums build results week by week.

Winter note (November–February)

Cold, dry air makes skin tighter and thirstier, so winter is when the order matters most: Hyaluronic Acid on slightly damp skin, then moisturiser to seal it in, and SPF every morning even when the sun feels weak. Niacinamide supports the skin barrier through the same months.

Quick answers

Can I use Vitamin C and Retinol on the same day? Yes — Vitamin C in the morning, Retinol at night. Never together in one sitting.

Can I mix two serums together? No — layer them, one after the other, thinnest first.

What if my skin reacts? Slow the frequency down before you stop altogether — fewer nights a week for Retinol, once a day to start for the others — and patch-test first next time.

Bottom line: 2–3 drops, the right time of day, and the same routine every day. Pick your serum by your #1 concern, give it weeks, and let consistency do the work.
