If you’ve spent any time looking at skincare products, you’ve probably come across ingredients like niacinamide and hyaluronic acid.
Both are extremely popular, but they serve different purposes. Understanding the difference can help you choose products that make more sense for your routine.
What Is Niacinamide?
Niacinamide is a form of vitamin B3 commonly used in skincare.
It is often included in products designed to improve the appearance of uneven skin tone, excess oil, blemishes and visible pores.
One popular example is The Ordinary Niacinamide 10% + Zinc 1%, which combines niacinamide with zinc and is designed for skin concerns including visible blemishes and excess oil.
What Is Hyaluronic Acid?
Hyaluronic acid is a humectant, meaning it helps attract and retain water.
It’s commonly used in skincare products designed to support hydration and give the skin a smoother, plumper appearance.
The Ordinary Hyaluronic Acid 2% + B5 is one example of a hydration-focused serum that can be incorporated into a skincare routine.
So Which One Should You Use?
That depends on what you’re trying to achieve.
If your main concern is hydration, hyaluronic acid may be a useful ingredient to look for.
If you’re more concerned about excess oil, blemishes or the appearance of uneven texture, niacinamide may be worth exploring.
And you don’t necessarily have to choose one over the other.
Depending on the products and your individual routine, both ingredients can have a place in the same skincare routine.
Can You Use Them Together?
Many skincare routines can incorporate both ingredients.
A simple approach could be to apply your hydration-focused product and then follow with your other skincare steps, according to the instructions provided for each product.
As with any new skincare product, introduce it gradually and pay attention to how your skin responds.
Final Thoughts
Skincare isn’t about chasing every trending ingredient. It’s about understanding what different products are designed to do and choosing products that make sense for your routine.
