Frequently Asked Questions

Answers to Your Frequently Asked Questions

What are the skin benefits of hyaluronic acid serum?

Hyaluronic acid is a powerful humectant that attracts and retains moisture resulting in improved skin hydration and plumpness. The Kiehl's hyaluronic acid serum helps to replenish the skin moisture barrier with hydration, enhancing the skin's overall appearance. This hydrating serum formula helps to achieve softer and more supple skin.

What skin type is the Ultra Pure High-Potency 1.5% Hyaluronic Acid Serum suitable for?

Can you use hyaluronic acid serum and glycolic acid together?

Yes, you can use hyaluronic acid serum and glycolic acid together in your skincare routine. These two ingredients complement each other and provide multiple benefits for the skin. Glycolic acid offers exfoliates dead skin cells from the surface, making way for fresh skin, while hyaluronic acid provides hydration and moisture retention. It is advisable to use the glycolic acid serum first, allowing it to fully absorb into the skin. Next, apply hyaluronic acid serum to replenish moisture and maintain hydration.

Can you use niacinamide with hyaluronic acid serum?

Yes, you can use niacinamide with hyaluronic acid serum. Niacinamide and hyaluronic acid offer different skincare benefits and can be used together to address various skin concerns. Niacinamide helps regulate sebum production, improve skin texture and reduce discolouration, while hyaluronic acid provides hydration and moisture retention. Combining these ingredients can result in improved overall skin appearance, hydration, and a more balanced complexion. To cleansed skin, apply niacinamide serum first, and follow with hyaluronic acid serum.

Can you mix hyaluronic acid and retinol?

Yes, you can mix hyaluronic acid and retinol in your skincare routine. Hyaluronic acid provides hydration and moisture retention, while retinol for skin helps encourage skin cell turnover and reduces the look of fine lines and wrinkles. First, apply retinol to a cleansed, dry face and allow it to melt into the skin. Follow with a hyaluronic acid serum to replenish skin moisture and counteract the drying effect some experience from retinol usage. Hyaluronic acid can form part of both your AM and PM skincare regimes, while retinol application should be reserved for the evening as it causes photosensitivity. Learn more about introducing retinol into your routine with our retinol for beginners guide - the key is to start slowly with a suitable concentration and build up the frequency with time.
