- Choose a serum that includes Vitamin E and Ferulic Acid to stabilize the active ingredients and keep them potent longer.
- Store your glass bottle in a cool, dark place to prevent the serum from oxidizing or turning an orange color.

Frequently Asked Questions
Should I apply vitamin C in the morning or at night?
Use it in the morning. Applying it before your sunscreen helps neutralize free radicals caused by UV rays and pollution throughout the day. It acts like a second layer of defense under your SPF.
Will vitamin C cause breakouts?
Pure L-ascorbic acid can be irritating for sensitive skin, but it is not inherently comedogenic. If you notice small red bumps, your skin might be reacting to the low pH level rather than the ingredient itself. Start with a lower concentration to see how your skin reacts.
Can I use vitamin C with retinol?
It is generally better to keep them separate to avoid unnecessary skin irritation. Use your vitamin C serum during the day and save your retinol treatment for your nighttime routine. Layering them together can overwhelm your skin barrier.
Does vitamin C expire?
Yes, and it happens faster than you might think. Most serums remain stable for about three to six months after opening. If the serum changes color or develops a strong metallic smell, it is no longer active and will not help your skin.
Is a derivative better than pure vitamin C?
Pure L-ascorbic acid is the most potent and well-studied form, but it is also the most unstable. Derivatives like sodium ascorbyl phosphate are gentler and more stable, making them a better choice if you have very sensitive skin. You trade a bit of immediate power for a much longer shelf life.
