The Role of Vitamin C in Skin Health

Vitamin C is a powerhouse antioxidant that plays a vital role in promoting clear, radiant, and youthful-looking skin. It helps neutralise free radicals, reduce inflammation, and encourages skin repair for a brighter complexion.

Besides brightening the skin, Vitamin C actively supports collagen synthesis, which is essential for maintaining firmness and elasticity. With consistent use, it can help combat early signs of ageing, diminish the appearance of fine lines, and improve overall skin texture. This makes it a must-have ingredient in your daily skincare routine, whether your focus is anti-aging, skin repair, or glowing skin.

Vitamin C also helps in reducing hyperpigmentation and sun-induced damage such as dark spots and uneven skin tone. Its protective benefits strengthen the skin’s barrier and improve resilience against environmental stressors like pollution and UV rays. Combined with a gentle cleanser like the OAT MILK FACE CLEANSER, Vitamin C serum can penetrate deeper and work more effectively, revealing fresher skin underneath.

Is Vitamin C Serum Better Used in the Morning or at Night?

Vitamin C serum can offer benefits both day and night, depending on your skin goals and pairing products.

In the morning, Vitamin C provides antioxidant protection against free radicals generated from sun exposure and pollution. Layering it under your SPF and moisturiser helps bolster your skin’s defense, keeping it brighter and more even while you go about your day. Using a high-quality Vitamin C serum in the morning amps up your skin’s natural glow and protects collagen reserves from degrading environmental triggers.

At night, Vitamin C helps stimulate cellular regeneration and collagen synthesis when your skin is naturally in repair mode. Applying a Vitamin C serum before bed enhances its potential to fade pigmentation and support elastin production. For those focused on anti-ageing and skin renewal, pairing Vitamin C at night with other rejuvenating products such as peptides or hydrating agents helps accelerate visible results.

Ultimately, consistency is key. Some users benefit more from twice-daily use, while others may prefer sticking to either AM or PM. You can also alternate days and complement nighttime routines with reparative products like the PRO AGE+ SUPER FACE SERUM that work synergistically with Vitamin C.

Best Practices for Applying Vitamin C Serum

Getting the most from your Vitamin C serum means knowing how and when to apply it effectively in your regimen.

Start with a clean canvas. Gently wash your face using a mild cleanser free of harsh actives. Opt for something like the OAT MILK FACE CLEANSER to remove impurities without stripping natural oils. Vitamin C tends to be more effective when applied to slightly damp skin, as hydration helps with absorption.

Apply a few drops to your fingertips and gently press the serum into your face and neck. Avoid rubbing excessively or layering too quickly with other strong actives, as this can irritate sensitive skin. Ideally, you should wait a minute or two before moving on to the next product in your routine so the serum can absorb fully.

Follow with a moisturiser to lock in the serum and further support your skin barrier. Morning routines should always finish with SPF to protect your renewed, radiant skin from UV damage.

Combining Vitamin C with Other Skincare Ingredients

Pairing Vitamin C correctly with other actives can maximise its visible benefits and address multiple skin concerns at once.

Vitamin C works well with hydrating agents like hyaluronic acid and nourishing ingredients like niacinamide. It’s also compatible with peptides and ferulic acid, which help stabilise Vitamin C and enhance its results. Using Vitamin C alongside these ingredients can improve hydration, reduce dullness, and accelerate skin brightness.

However, combining Vitamin C with strong exfoliating acids or high-strength retinoids should be done cautiously. These combinations can be too stimulating, especially if your skin is sensitive or already compromised. If you’re introducing new active products like retinol, use them on alternate days or split your routine between morning and night to avoid adverse reactions and keep your skin barrier healthy.

Some skincare bundles offer a curated solution for synergistic layering. For example, the PRO AGE + Skincare bundle includes a skin polish, serum, and moisturiser specifically designed to support anti-aging and glow-enhancing routines alongside Vitamin C use.

How Long Before You See Results with Vitamin C?

Patience pays off with Vitamin C, but results can vary based on concentration, usage frequency, and overall skin health.

Many users begin noticing improvements in skin tone, texture, and brightness within 2 to 4 weeks of consistent daily use. Collagen production and deeper pigmentation reduction can take a bit longer, generally around 6 to 8 weeks. Ensuring you’re following a supportive regimen that encourages cell turnover and hydration can enhance outcomes significantly.

For continuous improvement, it's recommended to use products with stable, potent forms of Vitamin C and complement them with a nourishing routine. A gentle exfoliator or skin polish used 2-3 times weekly, like the PRO AGE+ SUPER FACE SKIN POLISH, can help Vitamin C penetrate deeper by removing dulling dead skin cells.

While Vitamin C is powerful, it performs best within a complete system. Make it a consistent step in both your morning and evening routines, and support it with nourishing moisturisers, SPF, and adequate hydration to unlock your most glowing and resilient skin yet.
