Serums are super concentrated skincare products, and can penetrate the skin easier than a cream or a gel, making them more effective at tackling many skin concerns.
If you have acne-prone skin, retinoids and salicylic acid can help to reduce the appearance of blemishes.
If you have oily skin, you might think a serum will make your skin oiler, but there are water-based serums available that can replace your daily moisturiser.
If your skin is dry, you’d benefit from the added hydration of hyaluronic acid.
