Side Effects of Niacinamide Serum

Niacinamide is generally considered safe for all skin types, including sensitive and acne-prone skin. However, it's always wise to do a patch test before introducing any new product into your routine, especially if you have reactive skin.

Potential Side Effects:

1. Mild Irritation – While rare, some individuals may experience mild irritation or redness when first using a niacinamide serum.

2. Breakouts – In some cases, your skin may "purge" or experience breakouts initially, but this typically resolves after regular use.

If you're concerned about niacinamide serum side effects, consult with a dermatologist before use, especially if you have underlying skin conditions.
