How often should I use this product?
Start with 1-3 times per week to let your skin build tolerance, then increase gradually toward nightly use as tolerated. Always apply at night and follow with SPF the next morning.
Can I use this if I have sensitive skin?
Yes, but start slowly — once or twice a week for the first 2-3 weeks, then gradually increase. A small amount of redness, dryness, or peeling is a normal adjustment period. If irritation is severe or persistent, reduce frequency or consult a dermatologist.
What shouldn't I mix this with?
Avoid using it on the same night as Vitamin C, AHA/BHA exfoliants, or other high-strength actives. These combinations can increase irritation. Space them out on alternating nights instead.
When will I start seeing results?
Most people notice mild adjustment (dryness or peeling) in weeks 1-2, smoother-looking skin by weeks 4-8, and more visible improvement in fine lines and texture by weeks 8-12 with consistent use.
Is this product safe to use during pregnancy?
We recommend consulting your doctor before using retinol-based products during pregnancy or while breastfeeding, as retinoids are generally advised against during this time.
