Detailed answer

If you experience skin irritation or redness after using a serum, it is important to stop using the product immediately. This will help prevent further irritation and allow your skin to recover. To soothe your skin, gently wash your face with a mild cleanser and lukewarm water. Avoid using hot water or harsh cleansers that can further aggravate your skin. Pat your skin dry with a clean towel, being careful not to rub or irritate it. Apply a gentle, hydrating moisturizer that is free of fragrance and irritants to help calm and moisturize your skin. If the irritation persists or worsens, it is advisable to consult a dermatologist for further evaluation and guidance.
