Yes, it's generally a good idea to wait a short period, typically 30-60 seconds, between applying different skincare products. This allows each product enough time to absorb into your skin before the next layer is applied. Waiting helps prevent products from pilling or diluting each other, ensuring each product can work effectively. For very active or potent serums, some experts recommend waiting a bit longer, perhaps up to a minute or two.

While some serums can be mixed, it's generally best practice to apply serums one after the other, allowing each to absorb individually. Mixing them directly can sometimes reduce their effectiveness or stability, especially with certain active ingredients. For example, if you want to use a hydrating serum and a Vitamin C serum, apply the hydrating serum first, let it absorb, then apply the Vitamin C serum. The only exception might be if the product instructions specifically state that it's safe and effective to mix with other products.

Exfoliating acids (like AHAs or BHAs) should be applied after cleansing and toning, but before any serums or moisturisers. They help remove dead skin cells, allowing subsequent products to penetrate better. These are typically used 2-3 times a week, not daily. For face masks, apply them to clean skin after cleansing (and sometimes toning), following the product's specific instructions for duration. After rinsing off a mask, continue with your toner, serums, and moisturiser.

While a regular face moisturiser can offer some hydration to the eye area, eye creams are specifically formulated for the delicate, thinner skin around the eyes. They are often lighter in texture, less likely to cause irritation, and designed to target specific concerns like fine lines, dark circles, or puffiness without being too heavy or potentially migrating into the eyes. If you have specific concerns for your eye area, a dedicated eye cream can be beneficial, but if your regular moisturiser is gentle and non-irritating, it can be sufficient for basic hydration.

Facial oils are generally applied as the very last step in your evening skincare routine, after your moisturiser. This is because oils are occlusive, meaning they create a protective barrier on the skin. Applying them after your moisturiser helps to seal in all the hydrating and active ingredients you've applied previously, preventing moisture loss and providing an extra layer of nourishment. If applied before moisturiser, the oil could create a barrier that prevents your moisturiser from penetrating effectively. In the morning, most people skip facial oils if they are applying makeup, as it can sometimes make makeup slide or look too greasy.
