Yes, you can use The Ordinary Hyaluronic Acid and Niacinamide together in your skincare routine. Both of these ingredients offer different benefits for the skin and can complement each other effectively.

Hyaluronic Acid is a humectant that helps to attract and retain moisture in the skin, providing hydration and plumping effects. It can help to improve skin texture and reduce the appearance of fine lines and wrinkles.

Niacinamide, on the other hand, is a form of vitamin B3 that offers multiple benefits for the skin. It helps to regulate sebum production, minimize the appearance of pores, and improve skin tone and texture. Niacinamide also has anti-inflammatory properties, making it suitable for acne-prone skin.

When used together, hyaluronic acid can provide hydration to the skin while niacinamide helps to regulate sebum production and improve skin texture. It is important to note that The Ordinary Hyaluronic Acid has a low molecular weight, allowing it to penetrate deeper into the skin, while Niacinamide has a higher molecular weight, working on the surface of the skin.

To use these products together, you can apply The Ordinary Hyaluronic Acid first to clean, damp skin, allowing it to penetrate and provide hydration. After that, you can apply The Ordinary Niacinamide to the skin, focusing on areas of concern. Follow up with your moisturizer to lock in the hydration and complete your skincare routine.

It is always recommended to patch test new products and introduce them gradually into your routine to ensure compatibility with your skin. If you experience any irritation or discomfort, discontinue use and consult a dermatologist.
