Tea tree toner is primarily beneficial for acne-prone and oily skin. Its antiseptic properties help to cleanse pores, reduce inflammation, and control excess sebum production, leading to fewer breakouts.

Tea tree toner can be used daily, but it's important to monitor your skin's reaction. If dryness or irritation occurs, reduce usage to every other day or a few times a week.

While tea tree oil is often considered safe in diluted topical applications, it's best to consult with a doctor or dermatologist during pregnancy. They can provide personalized advice based on individual health conditions and potential risks.

Niacinamide and tea tree oil address different concerns. Niacinamide is beneficial for overall skin health, reducing redness and improving skin texture, while tea tree oil is specifically targeted for acne and inflammation. Consider your primary skin concern when choosing.
