What Is The Difference Between Vitamin C Serum vs Moisturizer?

The primary differences between a Vitamin C serum and a moisturizer lie in their consistency, formula, hydration, and potential for irritation.

Serums are lightweight and watery, allowing them to penetrate deeper into the skin cells, while moisturizers have a thicker formula that locks in moisture and supports the skin’s barrier.

Watery consistency

One of the key distinctions between Vitamin C serums and moisturizers is their consistency. Serums have a watery texture that allows them to penetrate deeper into the skin, removing dead skin cells and promoting a brighter complexion.

This deeper penetration enables serums to address specific skin concerns, such as skin pigmentation, collagen production, and brightening.

Thicker formula

On the other hand, moisturizers have a thicker formula that helps retain moisture and bolster the skin’s barrier. Supporting the skin’s barrier functionality prevents moisture retention and bacterial infiltration.

While serums target specific skin issues, moisturizers primarily provide hydration and barrier support, making them a popular choice for dry or sensitive skin.


Remember to factor in hydration when weighing the merits of serums and moisturizers. While serums are tailored to address specific skin issues, they may not hydrate as moisturizers.

With their thicker formulation, moisturizers provide a protective barrier and help retain moisture in the skin. There are certain Vitamin C serums with added formulas for hydration already included, such as Violoaskin's Vitamin C serum.


Serums may irritate some skin types due to their higher concentration of active ingredients. For sensitive skin, watch out for formulations containing alcohol or fragrance.

In contrast, Vitamin C moisturizers offer greater hydration and protection, making them a gentler option for sensitive skin types.

Vitamin C Serum: The Basics

Vitamin C serums target various skin concerns, such as hyperpigmentation, collagen production, and brightening, offering numerous benefits to your skin.

The potent antioxidant properties of Vitamin C also help protect the skin from environmental stressors and free radical damage.

They often contain additional ingredients like hyaluronic acid and glycerin, which provide added advantages such as hydration and anti-aging properties.

Lightweight hyaluronic acid

Vitamin C serums are typically lightweight and formulated with smaller molecules than moisturizers, allowing them to penetrate deeper into the skin.

This lightweight texture makes serums easy to apply and suitable for various skin types.

Serums often contain hydrating ingredients like hyaluronic acid, which aids in maintaining skin hydration and suppleness, and glycerin, which promotes moisture absorption into the skin.

These additional ingredients help decrease the visibility of wrinkles and fine lines, further enhancing the serum’s anti-aging effects.

Antioxidant properties

Vitamin C serums, containing ascorbic acid, offer antioxidant properties that can assist in combating detrimental toxins and safeguarding the skin from harm caused by free radicals.

These antioxidants help protect the skin from environmental damage, such as pollution and UV exposure, which can lead to premature aging and other skin concerns.

Incorporating a Vitamin C serum into your skincare routine gives your skin an extra layer of defense against these external stressors.

Collagen production

Collagen is a natural and essential protein for maintaining healthy skin, providing firmness and elasticity, and helping repair skin cells.

Vitamin C serums have been shown to stimulate collagen production, resulting in skin firmness, reducing the appearance of wrinkles and fine lines, and improving overall skin health.

Brightening and evening skin tone

Vitamin C serums have skin-lightening benefits that can assist in evening out skin tone and diminishing the visibility of dark spots and discoloration.

It improves your complexion's overall appearance and radiance while significantly enhancing the brightness and evenness of skin tone.

Is Vitamin C serum really worth it?

Vitamin C serums' effectiveness depends on your skin type and concerns.

While some may find that incorporating a Vitamin C serum into their skincare routine improves their skin’s appearance, others may not experience the same results.

Consider your skin care needs and seek a dermatologist’s advice to ascertain if a Vitamin C serum fits you.

Vitamin C Moisturizer: The Basics

Vitamin C moisturizers provide hydration and support for dry or sensitive skin while offering similar benefits to serums, such as targeting hyperpigmentation, collagen production, and brightening.

Moisturizing base

Moisturizers have a base that helps lock in hydration and create a protective barrier for the skin, ensuring that your skin stays hydrated and nourished throughout the day. Common ingredients used in moisturizing bases include:

  • Aloe vera

  • Natural oils

  • Shea butter

  • Hyaluronic acid

A Vitamin C moisturizer with a moisturizing base helps retain hydration while reducing irritation and redness.

Dry skin

A Vitamin C moisturizer is an excellent choice for those seeking additional hydration and nourishment, especially with dry skin.

The thicker formula of moisturizers works wonders in ensuring your skin stays hydrated and comfortable throughout the day. It effectively locks in moisture and nutrients, providing a long-lasting hydration effect.

Moreover, it also aids in strengthening the skin's barrier, protecting it from harmful environmental factors and preventing moisture loss.

Sensitive skin

For sensitive skin, a Vitamin C moisturizer may be a more suitable option due to its gentler formula and ability to provide additional hydration and barrier support.

Unlike serums, which can irritate some skin types due to their higher concentration of active ingredients, moisturizers are designed to nourish and protect the skin, reducing the likelihood of irritation and inflammation.

Barrier support

Vitamin C moisturizers offer several benefits for the skin, including:

  • Boosting the production of barrier lipids

  • Improving the skin’s natural protective capabilities

  • Helping the skin fend off environmental pollutants and irritants.

These benefits make Vitamin C moisturizers something to consider adding to your skincare regimen.

How to choose between Vitamin C serum or moisturizer?


Choosing between a Vitamin C serum or moisturizer hinges on your skin type and individual concerns.

Oily or acne-prone skin

You can benefit more from a lightweight Vitamin C serum if you have oily or acne-prone skin.

Serums are designed to penetrate deeper into the skin, and their lightweight texture makes them less likely to clog pores or cause breakouts, ideal for those with oily or acne-prone skin.

Dry or sensitive skin

A Vitamin C moisturizer is more suitable for those with dry or sensitive skin due to its hydrating properties.

Adding a Vitamin C moisturizer to your skincare regimen significantly alleviates dryness and leaves your skin feeling refreshed, smooth, and flexible.

Aging or mature skin

Effectively target signs of aging by using both products together.

Frequently Asked Questions

Is it better to use vitamin C as a serum or moisturizer?

Can I use vitamin C serum and moisturizer together?

You can use vitamin C serum and moisturizer together if you apply the serum first and give it time to absorb. Remember to use a gentle cleanser beforehand and follow with a broad-spectrum sunscreen in the morning. Finish the routine with a moisturizer that comes after your serum.
