Frequently Asked Questions
Can I use niacinamide after sun exposure?
Yes. Niacinamide helps calm inflammation and repair the skin barrier, so it's suitable for use after mild sun exposure. Avoid active brightening on open wounds or severe sunburn until healed, and always follow with moisturiser and broad-spectrum SPF during the day.
Will these serums make my skin more sensitive to the sun?
Niacinamide itself does not increase sun sensitivity. Some brightening ingredients that accompany niacinamide can make pigment changes more apparent as they work, but that does not mean increased photosensitivity. Still, daily SPF is essential while treating discoloration.
How long before I see results on dark spots?
Most users need consistent use for 4–12 weeks to see measurable fading, with some brand studies reporting perception changes around 4 weeks. Individual results vary based on spot depth, skin type, and sun protection habits.
