Understanding the Role of Vitamin C Serum in Skincare

Vitamin C serum is a staple in many skincare routines for its ability to brighten skin, even out tone, and protect against environmental damage. It’s packed with antioxidants that combat free radicals and promote collagen production for firmer, healthier-looking skin.

What makes it such a popular choice is its versatility—it suits all skin types and can be used to address a variety of concerns, from dullness and uneven texture to early signs of aging. However, questions about the right time of day to apply vitamin C serum—morning or night—remain a common topic of debate.

Morning Application: Harnessing the Antioxidant Power of Vitamin C

Using vitamin C serum in the morning helps protect your skin from daily environmental stressors such as pollution and UV rays. Vitamin C neutralizes free radicals generated from sun exposure and other urban pollutants, making it an important ally in preventive skincare.

When paired with a sunscreen, vitamin C can amplify your sun protection efforts. While it isn’t a substitute for SPF, it supports your skin’s barrier and helps mitigate the oxidative stress that leads to premature aging, hyperpigmentation, and collagen breakdown. The synergy between vitamin C and sunscreen makes morning the most effective time for antioxidant defense.

Even more, applying vitamin C serum in the morning can create a bright, radiant finish under makeup. Its fast-absorbing formula smooths the skin and helps give a more refreshed, glowing appearance. For best results, apply it after cleansing and before moisturizing.

If you’re also focusing on anti-aging and want to energize your skin for the day ahead, consider pairing your serum with a nourishing moisturiser like the PRO AGE+ SUPER FACE MOISTURISER. It locks in hydration and helps maintain the benefits of your serum throughout the day.

Nighttime Use: Repairing and Rejuvenating While You Sleep

Nighttime is when your skin naturally regenerates. Using vitamin C serum in the evening supports this process, helping to repair damage and stimulate collagen production while you rest. It can be especially beneficial for treating sunspots, fine lines, and acne scars over time.

Unlike the day, your skin isn’t subject to environmental stressors at night, which may allow for deeper absorption of active ingredients. Some people prefer nighttime application to prevent any interaction between vitamin C and sunlight, especially those with very sensitive skin. For these users, incorporating vitamin C into a calming, restorative routine can be a strategic choice.

Those who experience dryness or irritation with active serums might also find nighttime application ideal, especially when balanced with a soothing cleanser like the OAT MILK FACE CLEANSER. This gentle formula prepares your skin without stripping essential moisture, creating a perfect canvas for your actives.

If you’re alternating vitamin C with stronger nighttime treatments like retinol, use vitamin C in the morning and retinol in the evening to reduce the risk of irritation and maximize the benefits of both ingredients.

Twice-Daily Application: Is It Too Much?

Some skin enthusiasts consider using vitamin C serum both morning and night. If your product has a low to moderate concentration of vitamin C (10%-15%) and your skin is well-acclimated, this might be safe and beneficial. However, it’s not a necessity for achieving results and could potentially lead to sensitivity if overused.

The key is listening to your skin. Redness, flaking, or irritation are signs you’re overdoing it. It's often more effective to be consistent once a day than inconsistent twice a day. Splitting usage—morning for protection and night for repair—can help balance effectiveness and comfort. Also, always follow up with a moisturizer to reinforce the skin barrier.

How to Choose the Right Vitamin C Serum for Your Routine

Not all vitamin C serums are the same. Look for formulations that stabilize vitamin C and include complementary ingredients like hyaluronic acid or peptides to support skin hydration and elasticity. Stability is crucial because vitamin C can degrade quickly when exposed to air and light.

For those starting out or seeking advanced results, the PRO AGE+ SUPER FACE SERUM offers a balanced, antioxidant-rich formula crafted to address signs of aging and dullness. Its blend of active botanicals makes it suitable for daily use and helps maintain a youthful, vibrant complexion over time.

Pair your serum with a skincare regimen that includes sun protection during the day and nourishing treatments at night. Regardless of when you choose to use vitamin C, consistent application is the key to sustained improvements and a revitalized skin appearance.
