Frequently Asked Questions
Should I use my vitamin C serum in the morning or at night?
Always apply your vitamin C serum during your morning routine. It functions best as an antioxidant shield that defends your skin against environmental damage throughout the day. Layering it under your broad-spectrum sunscreen actually improves your overall sun protection. Applying it at night is fine, but you lose the daytime defensive benefits.
Why does my serum sometimes tingle when I put it on?
A mild tingling sensation is quite common with L-ascorbic acid because of its naturally low pH. Your skin is essentially adjusting to the acidic environment of the product. If the sensation turns into a burning feeling or causes visible redness, you should wash it off immediately. You might need a lower concentration or a gentler derivative.
Can I use vitamin C with my retinol or chemical exfoliants?
It is generally safer to separate these powerful ingredients to avoid over-exfoliation and irritation. Use your vitamin C in the morning and save your retinol or acids like BHA and AHA for your evening routine. Mixing them can disrupt your acid mantle, which is the thin, protective barrier on the surface of your skin. Keep your morning simple to maintain skin health.
How long does it take to see results?
Consistency is the secret ingredient here, so expect to wait about four to eight weeks to notice a visible difference. Brightening and evening out your skin tone takes time as your skin cells cycle through their natural renewal process. Take a photo before you start so you can track your progress accurately. It is easy to miss subtle changes when you see your reflection every single day!
Does the serum need to be refrigerated?
Most modern serums are formulated to be shelf-stable at room temperature if stored in a cool, dark place. However, keeping your bottle in the refrigerator can help slow down the oxidation process, especially if your bathroom stays warm and humid. Never freeze your serum, as that can damage the delicate formulation. A cool, dry cabinet is usually the safest spot for your daily skincare.
