What Does Vitamin C Do for Your Skin?

A timeless antioxidant with powerful results.

Vitamin C, especially in its most potent form, L-ascorbic acid, is one of the most trusted and researched ingredients in skincare. It acts like a shield for your skin, protecting it from free radicals. These are unstable molecules that build up from things like sun exposure, pollution, and everyday stress your skin deals with.

Here’s what Vitamin C is known for:

• Brightening dull skin

• Fading pigmentation and acne marks

• Supporting collagen production

• Boosting the effectiveness of sunscreen

What Are Copper Peptides in Skincare?

Copper peptides, often referred to in science as GHK-Cu, are short chains of amino acids naturally found in the body. They’re involved in wound healing, tissue regeneration and the production of essential proteins, such as collagen and elastin.

These molecules have been researched for decades. A 2018 article by Dr. Loren Pickart and Anna Margolina provides detailed insights into the benefits of GHK-Cu (copper peptides) for skin health. Like tightening loose skin, reversing thinning of aged skin, repairing protective skin barrier proteins, improving skin firmness, elasticity, and clarity, reducing fine lines and wrinkles, and stimulating wound healing.

It’s not a competition. It’s about knowing when to use what, because timing and skin type are crucial factors.

Inside the Bottle: What’s Really Powering These Serums?

Let’s break down the key ingredients behind the glow.

Before you decide between Vitamin C and Copper Peptides, it helps to know exactly what’s going into your skin. These aren’t just fancy names—they’re carefully selected formulas designed to target specific skin needs.

Can You Use Copper Peptides and Vitamin C Together?

It’s a common question, and honestly a smart one. Both copper peptides and vitamin C are powerhouse ingredients. But they work in very different ways. Vitamin C is acidic and highly reactive, while copper peptides are more fragile and prefer a stable environment to do their magic. When used incorrectly, they can clash, lowering each other’s effectiveness.

So what’s the fix? 

It’s all about timing. The safest and most effective way is to separate them in your routine:

• Morning: Go with Vitamin C Serum to protect against pollution and UV damage.

• Evening: Apply Copper Peptide Serum to help rebuild collagen and support skin repair overnight.
  
  

This gives your skin the best of both worlds—without triggering irritation or wasting product.

Which One Should You Use Based on Your Skin Goals?

Choose Copper Peptides if:

• You’re focused on firming, rebuilding, or healing

• You have sensitive or mature skin

• You’ve noticed deeper wrinkles, sagging, or post-inflammatory scarring

Choose Vitamin C if:

• You want to brighten, fade spots, or even skin tone

• You live in a city or experience high sun exposure

• You’re building a preventative skincare routine

Use both if:

• You want a full-circle anti-aging routine that protects in the day and repairs at night

• Your skin responds well to active ingredients and you can tolerate mild exfoliation or stimulation

Final Verdict: Which One Works Better?

Your skin doesn't need a 10-step routine. It needs the right steps at the right time.

Start your day with the glow-boosting power of True Skin Vita C Serum.
End your night with the firming strength of True Skin AR Copper Peptide Serum.

You don’t have to choose one over the other. You just have to know your skin, understand how these ingredients function and give them the space to work.

The best part? Neither of them are fads. Both are rooted in science. And both, when used thoughtfully, can deliver real results.
