When it comes to skincare, the terms facial oil and facial serum are often used interchangeably, leaving many confused about their purpose and place in a routine. While both are highly effective in nourishing and improving the skin, they serve distinct roles due to their composition, texture, and benefits. Here's a breakdown to help you choose the right product for your skincare needs.
What are the key Features of a Facial Oil?
Facial oils are plant-based or synthetic oil blends designed to lock in moisture and strengthen the skin’s natural barrier. They are typically formulated with botanical oils, essential oils, or other lipid-based ingredients.
Key Features:
Rich in Nutrients: Oils are packed with fatty acids, antioxidants, and vitamins that help soothe and protect the skin.
Moisture Sealing: They are occlusive, meaning they create a protective layer over the skin, preventing water loss.
Hydration Boost: Oils enhance hydration but don’t draw water into the skin; instead, they keep existing moisture locked in.
Best for Dry Skin: Ideal for those with dry or mature skin, facial oils are also effective in balancing sebum production for oily skin types.
How to Use Facial Oils:
Facial oils are best used as the last step of your skincare routine at night or before applying SPF during the day. This layering ensures the oil seals in all previously applied hydrating products like toners, essences, or serums.
What is a Facial Serum?
Facial serums are lightweight, water- or oil-based formulations containing high concentrations of active ingredients designed to penetrate deeply into the skin. They target specific concerns such as fine lines, hyperpigmentation, or acne.
Key Features:
High Concentration of Actives: Serums are packed with active ingredients like hyaluronic acid, vitamin C, niacinamide, or peptides.
Lightweight Texture: They are thinner and absorb quickly, ensuring that the active ingredients work effectively at deeper skin levels.
Targeted Treatment: Different serums cater to different skin issues, making them a versatile choice for customising your routine.
Universal Appeal: Suitable for all skin types, though the choice of serum should align with individual skin concerns.
How to Use Facial Serums:
Apply serums immediately after cleansing and toning, but before moisturisers and facial oils. This ensures that their active ingredients can penetrate effectively without barriers.
Key Differences Between Facial Oils and Serum

Facial Serum

Should You Use Both?
Facial oils and serums complement each other rather than compete. If your skin requires targeted treatment and moisture sealing, incorporating both can be beneficial. Layer a serum first to address skin concerns, then follow with a facial oil to lock in hydration. However, always consider your skin type and the product formulations to avoid overloading the skin.
Final Thoughts
The choice between facial oil and serum comes down to your skin's needs. If you’re looking for a boost in hydration and protection, facial oils are your go-to.
On the other hand, if you want to tackle specific concerns like dark spots or fine lines, serums are the answer. The best skincare routines often include both, used strategically to maximise their unique benefits.
