Foundation 101 — How to Choose the Right Shade Without Guessing

Hey, Glaminai here — and if you’ve ever found your “perfect” foundation turning orange, ashy, or patchy by lunch, let’s fix that for good.

🩵 The Problem

You match foundation under harsh store lights, swipe it on your hand, and somehow it oxidizes or mismatches the second you step outside.
That’s not your fault — it’s undertone confusion and oxidation working against you.

🔍 Why It Happens

1. Undertones ≠ Surface color

   • Cool: pink/blue undertones → veins look purple-blue.

   • Neutral: balanced tone → veins shift blue-green.

   • Warm: golden/yellow undertones → veins look green.
     Match your undertone, not just your shade depth.

2. Oxidation: foundation darkens as it mixes with skin oil or air.
   Tip: always test on your jawline and wait 10 minutes before judging.

3. Lighting lies: indoor bulbs distort tone. Check your match in daylight near a window.

⚡ Quick Fix: Match, Test, Confirm

• Swipe 3 shades from cheek to neck.

• Step into natural light.

• The one that disappears is your match.

• Use a damp sponge for sheer coverage — it helps you see tone clarity before committing.

✨ Glaminai Recommends:

• Fenty Pro Filt’r (60+ shades, true undertone options)

• NARS Light Reflecting Foundation (skin-like finish)

• L’Oréal True Match (affordable and accurate)

🚫 Mistakes to Avoid

• Matching to your wrist or hand (they’re different tones).

• Picking by shade name instead of undertone.

• Forgetting about oxidation — always wait a few minutes before deciding.

💬 Ask Glaminai to instantly match your undertone and foundation shade range based on your skin photo — no guessing, no wrong aisle lighting.
