Q: How do hormonal cycles affect product tolerance?

A: Hormonal fluctuations can impact skin sensitivity: 

• Menstrual sensitivity: Skin may be more reactive during menstrual cycle 

• Retinol adjustment: May need to reduce 3% retinol frequency during sensitive periods 

• Breakout management: Pimple patches particularly helpful for hormonal acne 

• Cycle tracking: Monitor skin patterns throughout cycle to optimize routine timing 

• Hydration focus: Extra Hyaluronic Acid during hormone-related dry periods
