Authenticity: Make sure you buy from a reputable seller. Korean imports may face issues of authenticity/counterfeit.Packaging/expiry: Vitamin A derivatives degrade with time/light/air. Ensure sealed packaging, check manufacture/expiry date.Skin-type/concerns: If you have very sensitive skin, active acne or compromised skin barrier, you might want to start with milder retinol or even seek dermatologist advice.Sun protection: Because this increases sun sensitivity, a strong daily sunscreen (SPF 30/50+) is non-negotiable.Price & value: Check shipping/import costs and customs (if buying internationally).Layering: Avoid combining with other strong actives (like exfoliating acids) on same night initially to reduce risk of over-irritation.
