This explains why you might feel a brief burning after applying Melaglow and how long results typically take.

🩺 Symptoms

• Mild burning for ~5 minutes after application, started after 4–5 days of nightly use; you apply VCX serum before Melaglow.
• No mention of widespread redness, blisters, or breathing difficulty.

⚕️ What this likely is

• Mild irritant reaction from active ingredients (product lists kojic acid 2% and niacinamide 4%) or layering with the VCX serum.
• Transient stinging as skin adjusts is common in the first week with brightening actives.
• Allergic contact dermatitis is less likely but possible if symptoms worsen or persist.

🏥 What to do now

• Hold Melaglow for 48 hours and stop the VCX serum to see if the burning stops.
• Use a gentle cleanser and a bland moisturizer; apply cool compresses for comfort.
• If you restart, do a patch test (small area) and introduce products one at a time.
• See a dermatologist if the reaction recurs or you want guidance on safe layering and alternatives.

✅ How long to see results

• Products with kojic acid/niacinamide typically need about 4–8 weeks of consistent use for visible lightening; full effect may take longer.
• Use daytime sun protection (SPF (sun protection factor) 30+) daily to support results.

⚠️ When to seek urgent care

• Seek immediate care or call emergency services if you have facial swelling, spreading redness/blisters, or breathing difficulty.

If you want, I can suggest a gentle restart plan or alternative ingredients to try.
