Ultra Pure High-Potency 5% Niacinamide Serum

Niacinamide serums offer an array of benefits to skin, especially if you experience excess oiliness. Niacinamide is a form of vitamin B3 that is commonly used to regulate sebum production, minimise the appearance of pores and skin imperfections while also enhancing skin moisture barrier function. After using the Kiehl's niacinamide face serum, you should notice an improvement in the overall appearance of skin.

The Kiehl's Niacinamide Serum is suitable for all skin types including sensitive. It can be particularly beneficial for those with oily or acne-prone skin due to its sebum-regulating properties. However, it is always a good idea to patch test new products and consult with a dermatologist or skincare professional to determine if this product is suitable for your skin.

Niacinamide face serum can be applied in both your morning and night time skincare routines. Use after cleansing and toning skin and always follow with a moisturiser. Remember to always apply a sunscreen with SPF in the morning to protect the skin.

Niacinamide and vitamin C offer unique benefits and together can create a powerful combination to improve overall skin clarity. These ingredients are safe to layer, however it is always a good idea to patch test before use and introduce them slowly into your routine to prevent skin discomfort. To layer a niacinamide face serum with vitamin C, we recommend applying vitamin C first before following with the niacinamide serum.

Yes! Niacinamide helps regulate sebum production, improves skin texture, and enhances the skin moisture barrier, while hyaluronic acid provides hydration and plumping effects. Combining these ingredients in your skincare routine can help you address multiple concerns simultaneously. To layer these ingredients we recommend using the niacinamide serum first and following it with the hyaluronic acid serum.
