Discover the differences between ILIA's True Skin Radiant Priming Serum and traditional primers, and find out which is better for your skin type and makeup goals.
When it comes to prepping your skin for makeup, the primer aisle can feel overwhelming. Traditional silicone-based primers promise to blur pores and extend wear, while newer serum-primers like ILIA's True Skin Radiant Priming Serum claim to care for your skin while creating a smooth canvas. But which one truly delivers? In this comparison, we'll break down the key differences, benefits, and skin types each is best suited for.

Whether you're a makeup minimalist or a full-glam enthusiast, understanding how a primer interacts with your skin is crucial. Let's dive into the world of priming serums versus traditional primers to help you make an informed choice for your beauty routine.
What Is a Traditional Primer?
Traditional primers have been a makeup bag staple for years. They're typically formulated with silicones (like dimethicone) or polymers that create a smooth, velvety layer over the skin. This layer helps to fill in fine lines, minimize the appearance of pores, and provide a grippy surface for foundation to adhere to, which can extend the wear of your makeup.
However, while traditional primers excel at creating a temporary, poreless-looking finish, they often sit on top of the skin rather than being absorbed. This can sometimes lead to a heavy or suffocating feel, and for those with sensitive or acne-prone skin, silicones can occasionally cause congestion or breakouts. They also tend to offer little to no skincare benefits beyond their cosmetic effect.
- Creates a smooth, blurred effect on the skin
- Helps makeup last longer throughout the day
- May feel heavy or clog pores for some skin types
- Limited skincare benefits
What Is a Priming Serum?
Priming serums are the hybrid heroes of the beauty world. They combine the skin-nourishing properties of a serum with the makeup-prep benefits of a primer. ILIA's True Skin Radiant Priming Serum is a prime example—it's formulated with skin-loving ingredients like niacinamide, squalane, and botanical extracts that hydrate, plump, and brighten the skin while also creating a smooth, radiant base for makeup.
Unlike traditional primers, a priming serum is absorbed into the skin, delivering active ingredients that improve your skin's health over time. It addresses issues like dullness, dehydration, and uneven texture at the source, rather than just masking them temporarily. The result is a natural, lit-from-within glow that shines through your foundation, rather than a flat, matte canvas.
- Provides skincare benefits with continued use
- Lightweight and breathable on the skin
- Creates a radiant, healthy-looking base
- Suitable for most skin types, including sensitive
Key Differences: Texture, Finish, and Skincare Benefits
The most noticeable difference between a traditional primer and a priming serum is the texture. Traditional primers often have a thick, silicone-based feel that instantly smooths the skin's surface. Priming serums, on the other hand, have a lighter, more fluid consistency that sinks in quickly, leaving the skin feeling soft and hydrated rather than coated.
In terms of finish, traditional primers typically offer a matte or velvety finish, which can be great for oily skin or long events. Priming serums like the True Skin Radiant Priming Serum deliver a dewy, radiant finish that enhances your natural glow—perfect for dry or dull skin. When it comes to skincare, the serum wins hands down, as it nourishes your skin with every use, while traditional primers offer no long-term benefits.
- Texture: Traditional primers are thicker; priming serums are lightweight and fluid.
- Finish: Traditional primers often matte; priming serums provide a radiant glow.
- Skincare: Priming serums contain active ingredients; traditional primers do not.
- Skin feel: Priming serums feel breathable; traditional primers can feel heavy.
Which Is Better for Your Skin Type?
Choosing between the two depends largely on your skin type and makeup preferences. If you have oily skin and struggle with shine, a traditional mattifying primer might be your best bet for keeping makeup in place. However, if you have dry, dehydrated, or mature skin, a priming serum like the True Skin Radiant Priming Serum will provide the hydration and glow your skin craves, while also smoothing the surface for foundation.
For combination skin, a priming serum can be a versatile option, as it hydrates dry areas without making oily zones greasy. And if you're someone who prefers a natural, skin-like makeup look, a serum primer is ideal—it enhances your skin rather than masking it. On the other hand, if you're heading to a long event and need your makeup to last through hours of wear, a traditional primer might offer more longevity.
It's also worth noting that the True Skin Radiant Priming Serum works beautifully under the True Skin Serum Foundation, which is another standout product from ILIA. Together, they create a seamless, skin-like finish that looks like your skin, but better.

- Oily skin: Traditional mattifying primers may control shine better.
- Dry or dull skin: Priming serums provide hydration and glow.
- Combination skin: Priming serums offer balanced hydration.
- Natural makeup lovers: Priming serums enhance skin, not mask it.
How to Use a Priming Serum for Best Results
To get the most out of your priming serum, apply it after your moisturizer and before your foundation. Start with a clean, toned face, then gently press a few drops of the True Skin Radiant Priming Serum into your skin. Allow it to absorb for a minute or two—this gives the active ingredients time to work and ensures a smooth base.
For an extra boost of radiance, you can also mix a drop of the serum with your foundation. This creates a more luminous finish and adds an extra layer of hydration. If you're using a brush, like the Shadow Brush from ILIA, to apply your foundation, the serum will help the product glide on effortlessly, preventing any patchiness or streaks.
- Apply on clean, moisturized skin before foundation.
- Allow the serum to absorb for 1-2 minutes before applying makeup.
- Mix a drop with your foundation for extra glow.
- Use a brush or sponge for an even application.
So, which is better—True Skin Radiant Priming Serum or a traditional primer? The answer depends on your skin's needs and the finish you desire. If you crave skincare benefits and a natural, radiant glow, the serum primer is the clear winner. If you need heavy-duty oil control or maximum longevity for a special occasion, a traditional primer might still have its place. But for daily wear and long-term skin health, a priming serum is a smart investment. Ready to elevate your makeup routine?
