Frequently Asked Questions
Should I apply vitamin c in the morning or at night?
Apply your serum in the morning before sunscreen. It functions as a shield against daily pollutants and UV-induced free radicals. Using it during the day maximizes your long-term glow.
Can I use vitamin c with retinol?
Avoid using these two at the exact same time to prevent potential irritation. Apply your vitamin C during the day and save your retinol treatment for your evening routine. This split approach keeps your skin barrier happy and healthy.
Why does my serum smell like hot dogs?
That distinct, metallic aroma is a common trait of pure L-ascorbic acid. It does not necessarily mean the product has gone bad. If the scent is faint, you can continue using the serum as directed.
Will vitamin c help with my acne scars?
Yes, it is excellent for fading dark spots and evening out skin tone over time. Consistent use helps inhibit melanin production, which gradually lightens hyperpigmentation. Patience is essential, as results usually appear after several weeks.
How do I know if the serum has oxidized?
A fresh serum is typically clear or pale yellow. If you notice the liquid has transitioned to a deep amber color, the potency has significantly dropped. An oxidized product will not provide the same benefits and could potentially cause minor breakouts.
