Steps
Check the serum before you put it on your face. Fresh pure ascorbic acid is almost colourless. If it has turned yellow, orange or brown like apple juice, it has oxidized and is no longer treating melasma.
Test a new bottle the day you open it, then look at it again every couple of weeks. The small ascorbic acid molecule starts reacting with air and light as soon as the seal breaks.
Choose a serum packaged to keep air and light out, and buy the smallest size you will finish within a few months. A strong formula is useless once it has degraded in the bottle.
Start with a clean, dry face in the morning. Apply the serum after cleansing and before your moisturiser, patting a few drops over the whole face, including the pigmented patches.
Wait about one minute for the serum to absorb. The 20-minute wait between skincare steps is a myth; one minute is enough for a leave-on serum before the next layer.
Follow with a broad-spectrum SPF 30 or higher every morning. UV light creates the free radicals that push melanocytes into overdrive, so sun protection guards your progress.
Use it daily and judge the result after several weeks, not after a few days. Pigmentation fades slowly, and consistency matters more than using a higher percentage.
Tips and common mistakes
Store the bottle in a cool, dark cupboard, not a sunny bathroom shelf, and close the cap tightly every time.
Patch test on your inner arm for a day first if your skin is sensitive, since 20% ascorbic acid can sting.
Vitamin C helps fade pigmentation but does not replace prescription melasma treatment from a skin doctor.
Do not mix a fresh serum into an old brown one to save it. The whole bottle is compromised.
Questions
How do I know if my vitamin C serum has gone bad?
Fresh pure ascorbic acid is nearly colourless. Once it looks yellow, orange or brown like apple juice, it has oxidized and you should replace it rather than keep using it.
Do I really need to wait 20 minutes after vitamin C?
No. About one minute is enough for a leave-on serum to absorb before you apply sunscreen or moisturiser.
Can vitamin C alone fade melasma?
It helps by calming the free radicals and tyrosinase activity behind pigmentation, but results vary from person to person. Use daily sunscreen and see a skin doctor if patches do not improve.
