Experiencing an increase in pimples during pregnancy is common due to hormonal changes. To manage this issue, there are several steps you can take. Firstly, maintain a regular skincare routine by cleansing your face twice daily with a gentle cleanser. Avoid using harsh products that may irritate your skin further. Secondly, keep your skin hydrated by using oil-free moisturizers suitable for acne-prone skin. Additionally, make sure to drink plenty of water throughout the day to keep your body hydrated from within. As for turmeric powder and warm water, it can be used as a natural remedy for acne due to its anti-inflammatory properties. However, it is always advisable to consult with your healthcare provider before trying any new remedies or supplements during pregnancy. They will be able to guide you based on your specific situation and medical history.
