What is Vitamin C?
Vitamin C is one of the most popular skincare ingredients for a reason. It’s known for helping brighten the skin, fade dark spots and give a more radiant, even look overall. If your skin looks dull, tired or uneven, Vitamin C can make a noticeable difference when used consistently.
Here’s a straightforward breakdown of what it does, how it works and how to use it properly in your routine.
What Vitamin C Does For Your Skin
Vitamin C is a powerful antioxidant, which means it helps protect your skin from things that make it look dull or damaged over time, like pollution and UV exposure. It also plays a big role in brightening the complexion and improving overall clarity.
People reach for Vitamin C to help with:
• Dull or uneven skin
• Dark spots and post-acne marks
• Rough texture
• Early signs of ageing
• Lack of glow or radiance
It supports the skin’s natural ability to look smoother, clearer and more “awake.”
Why It Helps With Dark Spots
Vitamin C helps slow down the process that creates excess pigment in the skin. Over time, this makes dark spots, sun spots and marks left behind after breakouts less noticeable. It won’t change your natural skin tone — it just helps it look more even.
Who Vitamin C Is Best For
Vitamin C works well for most skin types. It’s especially helpful if you want to brighten your skin, even your tone or reduce the appearance of marks.
It’s great for:
• Normal, dry or combination skin
• Hyperpigmentation or sun damage
• Dull or uneven tone
• Skin that needs a boost in radiance
If you have very sensitive or reactive skin, you can still use Vitamin C — just start with a gentle formula, use it every other day at first and keep the rest of your routine simple.
When To Use Vitamin C
Vitamin C works best in the morning. It helps protect your skin throughout the day and boosts the effectiveness of your sunscreen. You can use it at night too, but morning use gives you the most benefits.
You can use it once a day or every other day depending on what your skin prefers.
What Not To Mix With Vitamin C
Stronger forms of Vitamin C (like pure L-ascorbic acid) don’t always pair well with certain ingredients if your skin is sensitive.
Try to avoid using it at the same time as:
• Strong exfoliating acids
• Retinol (if you’re new to both ingredients)
• Very high-strength Niacinamide
This doesn’t mean you can’t use these ingredients at all — just use them at different times of the day, like Vitamin C in the morning and retinol or exfoliants at night.
What Works Well With Vitamin C
Vitamin C works really nicely with hydrating and calming ingredients. Hyaluronic Acid, Aloe Vera and Centella are great companions because they keep the skin comfortable and smooth.
If you’re focusing on dark spots or acne marks, Vitamin C also pairs well with gentle brighteners like Arbutin and even Niacinamide (when used in separate routines or gentle percentages).
How Long It Takes To See Results
Most people notice their skin looking more even and awake within two to four weeks. Dark spots and sun damage take a bit longer, usually around six to eight weeks of consistent use. The key with Vitamin C is patience and consistency — it pays off.
How To Use Vitamin C Correctly
A simple way to use Vitamin C is after cleansing, on dry skin. Apply a few drops, let it absorb and then follow with moisturiser and sunscreen. If you’re new to it, start every other morning and slowly build up to daily use.
The Skin-T Vitamin C Serum
Skin-T’s Vitamin C serum is made to brighten the skin, support an even tone and give a fresh, healthy-looking glow. It works well in both simple and multi-step routines and layers easily under moisturiser and SPF.
