Frequently Asked Questions
Can I use niacinamide and hyaluronic acid together after sun exposure?
Yes. Niacinamide calms redness and supports the skin barrier while hyaluronic acid hydrates and plumps. Use a gentle niacinamide cleanser or cream to soothe, then layer a hyaluronic booster on damp skin to lock in moisture.
Should I use vitamin C immediately after sun exposure?
Avoid introducing active vitamin C to freshly sunburned or inflamed skin—it can sting. Wait until redness subsides and the barrier is restored (use niacinamide and hydration first), then add vitamin C to treat tone and pigmentation with daily SPF.
Which product order is best in a post-sun routine?
Cleanse first with a gentle niacinamide cleanser if needed, apply a lightweight hyaluronic booster while skin is damp, then follow with a moisturizer for barrier repair. Finish with sunscreen in the daytime.
