Detailed answer

The timeframe for an allergic reaction to occur after using a skincare product can vary from person to person. Some individuals may experience an immediate reaction within minutes of applying the product, while others may notice symptoms hours later. It is important to note that the severity and duration of the reaction can also vary. Mild reactions may include redness, itching, or a rash, while severe reactions can manifest as hives, swelling, or even difficulty breathing. If you suspect an allergic reaction, it is crucial to stop using the product immediately and seek medical advice for proper evaluation and treatment.
