Skincare can often feel overwhelming, as it involves selecting the appropriate products and applying them in the correct sequence. Are you aware of the ideal order for a skincare routine? Or are you among the many who find themselves puzzled about whether to apply serum or moisturizer first?
Both serum and moisturizer play crucial roles in your skincare regimen. When utilized correctly, they can significantly enhance the health and appearance of your skin. Typically, serums are applied before moisturizers; however, this isn't a strict rule, as various factors including the desired outcomes and specific products can influence the application order.
Let's delve into the distinctions between serum and moisturizer, and clarify which should be applied first in your routine.

Part 1: Serum vs. Moisturizer: Understanding the Differences
Before we explore the major differences, it’s essential to grasp what serum and moisturizer are. Below, we define each product to assist you in discerning their unique functions and uses.
What is Serum?
A serum is a skincare formulation characterized by smaller molecular sizes, which facilitates deeper penetration of active ingredients into the skin, thereby yielding more pronounced results. This concentrated product targets specific skin concerns, providing treatment for various issues.
Unlike facial oils, serums are lightweight and non-greasy, and they serve distinct purposes. While they bear some resemblance to essences, which tend to be thicker and stickier, not all serums possess that same sticky quality.
How to Select the Right Serum for Your Skin?
Serums can be categorized as either oil-based or water-based. If you have dry skin, oil-based serums are ideal, whereas water-based serums suit those with oily skin. Choosing a serum should be based on your skin type and specific concerns. Common issues that serums can address include:
What is Moisturizer?
A moisturizer is a formulation that combines emollients and humectants, resulting in a balm or lotion-like texture that enhances hydration and provides protection to the skin’s barrier. The primary function of a moisturizer is to lock in moisture and nutrients, thus maintaining the skin's hydration levels.
Moisturizers serve four key purposes:
- They lock in moisture.
- They hydrate the skin.
- They improve skin texture by addressing inflammation and dryness.
- They contribute to long-term skin health by maintaining a robust skin barrier, which is crucial for maximizing the effectiveness of other skincare products.
Key Differences: Serums vs. Moisturizers
Now, let's outline the key differences between serums and moisturizers to help clarify their respective roles:
Consistency: Serums typically have a runny consistency, although some may be slightly thicker. In contrast, moisturizers are generally thick, creating a protective layer on the skin.
Texture: Designed for absorption, serums are lightweight and penetrate the skin quickly. Moisturizers, with their creamy texture, remain on the surface of the skin, although they are non-sticky.
Ingredient Concentration: Serums contain a higher concentration of ingredients tailored to specific skin concerns and typically have shorter ingredient lists. Moisturizers, being more generalized skincare products, contain a lower concentration of active ingredients and often have a more complex formulation.
Ingredient Type: While moisturizers include barrier-repairing components such as occlusives, ceramides, and emollients, serums focus on addressing specific skin issues with ingredients like niacinamide, AHAs, BHAs, and PHAs. The concentration of these ingredients may vary based on skin type and concerns.
Usage: Since moisturizers generally lack active ingredients, they can be used by anyone. In contrast, serums are concentrated and might require dermatological guidance or thorough research on their ingredients before use.
Application Timing: Moisturizers can be applied at any point in your routine without limits on frequency. However, some serums are recommended for nighttime application only; thus, it's essential to check the serum's photosensitivity and stability prior to daytime use.
Penetration Level: Serums often address issues at the deeper layers of the skin, providing targeted nourishment based on your specific concerns. Moisturizers, on the other hand, primarily function on the skin's surface, preventing moisture loss and dryness.
Purpose: Serums and moisturizers are designed for different objectives. Moisturizers focus on hydration and softness, while serums aim to treat and rectify specific skin problems. While most moisturizers share similar goals, each serum serves a distinct purpose determined by its ingredient concentration.
Moisturizer application is a vital step in any skincare routine. It is essential to never skip this step, regardless of your skin type. Serums can be an added layer to your regimen, utilized as needed, but a foundational routine should always include a moisturizer.
Stability: Moisturizers tend to maintain their integrity even when exposed to sunlight and generally have a longer shelf life. Conversely, some serums may destabilize over time; for instance, vitamin C serums can degrade and lose effectiveness when subjected to heat or direct sunlight.
Part 2: Which Comes First, Serum or Moisturizer?
The prevailing belief is that serum should be applied first, followed by moisturizer. This order is based on two main reasons:
However, there are exceptions; for certain retinol serums, it's advisable to apply moisturizer first to minimize irritation. This method, often referred to as the "sandwich method," involves applying moisturizer, followed by the retinol serum, and then another layer of moisturizer.
Here’s the recommended skincare application order you should adhere to:
Part 3: FAQs About Applying Both Serum and Moisturizer
Can You Combine Serum with Moisturizer?
Absolutely! You can mix serum with your moisturizer. Simply place 2-3 drops of serum in your palm, blend it with your moisturizer, and then apply it to your face. However, it's essential to examine the ingredient lists of both products to ensure compatibility and avoid any potential irritation.
Is It Okay to Leave Serum on Overnight Without Moisturizer?
This question has two schools of thought. Some individuals believe it's fine to use serum alone, while others argue that serums lack the necessary hydration alone. Therefore, it's generally advisable not to leave serum on overnight without applying moisturizer, as this could lead to dryness and exacerbate breakouts.
