Frequently Asked Questions
Should I keep my vitamin c serum in the refrigerator?
Storing your serum in a cool, dark place like a drawer or medicine cabinet is usually sufficient. If your bathroom gets very warm and humid, keeping the bottle in the refrigerator can help slow down the oxidation process. Just ensure you keep it in a spot where the temperature stays consistent. Extreme cold is not necessary, so do not feel obligated to put it in the freezer.
Can I use vitamin c with my retinol at night?
It is generally best to separate these two powerhouses. Apply your Vitamin C in the morning to shield your skin from environmental stressors. Save your retinol for your evening routine to avoid potential irritation. Layering them together can sometimes be too intense for your moisture barrier to handle.
Why does my serum sometimes sting when I apply it?
A slight tingling sensation is common when you first introduce L-ascorbic acid into your routine. This is usually just the low pH of the formula doing its job. If the stinging turns into burning or leaves your skin bright red, you should rinse it off immediately. You might need a lower concentration or a gentler vitamin C derivative.
Is it okay to use vitamin c if I have acne?
Yes, Vitamin C can actually help fade the post-inflammatory hyperpigmentation left behind by old breakouts. It promotes an even skin tone while providing antioxidant protection. Just make sure the formula is non-comedogenic, which means it will not clog your pores. Check the label for oil-free ingredients if you are concerned about breakouts.
How long does it take to see actual results?
Skin cycling takes time, so be patient. You will typically notice a brighter complexion within four to six weeks of consistent daily use. Fading dark spots or deeper scarring takes longer, often requiring three months or more of steady application. Stick with your routine and always wear sunscreen during the day to prevent new spots from forming.
