Introduction: The Big Question of Order in Your Skincare Routine

Do you ever ask yourself, "Face oil or moisturizer – which comes first?" You're not alone. This is one of the most frequently asked questions in the world of skincare, and for good reason: the order of application can influence the effectiveness of your products.

In this expert article for Dermi.fr, we will:

• explain why order truly matters;
• detail what makes a face oil and a moisturizer;
• give you clear recommendations based on your skin type;
• and share practical tips to optimize your routine.
  Let's review this topic together so that your skincare products work to their maximum potential.

Understanding the Functions: Face Oil vs. Moisturizer

What is a face oil?

A face oil is a lipid-based product – often of plant origin (jojoba, argan, rosehip, squalane) – designed to:

• nourish the skin with essential fatty acids, vitamins, antioxidants;
• form an occlusive film on the skin's surface to limit water loss (TEWL).
  This role is particularly useful for dry, mature, or harsh-climate-exposed skin.

What is a moisturizer?

A moisturizer is a product typically water-based, containing:

• humectants (e.g., glycerin, hyaluronic acid) that draw water to the skin;
• emollients that soften it;
• sometimes light occlusives to "seal" in hydration.
  Its role: to hydrate, plump, and restore the skin barrier.

Why is the order of application important?

The key principle: apply from the thinnest and lightest to the thickest and most occlusive.

“The general rule of thumb in skincare is to apply products in order of texture, from lightest to heaviest.”
If you apply oil before cream, the oil, being more occlusive, can prevent the water-based cream from penetrating properly. This reduces its effectiveness.

The General Rule: Light Texture → Thicker Texture

 For most routines, the recommended order is:
Serum (optional) → Moisturizer → Face Oil
Explanation: the moisturizer (water-based) can penetrate well, then the oil comes to "lock in" the provided hydration.
This is the most frequently recommended approach by specialists.

When to Apply Oil Before Moisturizer?

However, there are cases where oil can come before cream:

• If the oil is very light, quickly absorbed (e.g., squalane, grapeseed oil) and formulated to penetrate.
• If you have extremely dehydrated skin and want to first provide a lipid layer, then reinforce with a cream.
• If the moisturizer is very light, almost a gel, and the oil acts as the primary treatment.
  In these cases, the oil acts as a treatment, then the cream as a finish.

When to Apply Oil After Moisturizer?

For most skin types and in most climates, oil comes after cream:

1. It helps to "seal" in the hydration provided by the cream.
2. It protects the skin barrier, limiting transepidermal water loss.
3. It is ideal for the evening routine or for dry/normal skin.
   This approach will maximize the hydrating and nourishing effect.

Tips (Face Oil or Moisturizer)

• Wait 30 to 60 seconds after applying the cream before applying the oil. This allows the cream time to penetrate.
• Use 2 to 3 drops of oil for the face and neck. Applying too much oil can "smother" the skin or clog pores.
• Warm the oil in your palms before applying it for optimal absorption.
• In the morning: prioritize light textures before sun protection (SPF). Oil can leave too occlusive a finish under makeup.
• In the evening: this is often the best time to apply oil + cream, as the skin regenerates.
• Adjust according to climate: in cold or dry climates, stronger occlusion (oil after cream); in hot/humid climates, lighter textures or oil before cream.
