Setup and Application:nThe Sigma Beauty Eyeshadow Base Primer in Persuade is ready to use right out of its packaging. Simply remove the cap and gently twist the base to reveal more product if needed. It requires no additional setup.nnCompatibility:nThis primer is designed to work seamlessly with most powder and cream eyeshadows from various brands. Its formula creates an ideal tacky base for enhancing both matte and shimmer finishes. For best results, it pairs well with Sigma Beauty eyeshadows and pigments.nnCare and Maintenance:n* Storage: Store the primer in a cool, dry place away from direct sunlight or extreme temperatures to prevent the product from melting, drying out, or altering its consistency.n* Cap Securely: Always replace the cap tightly after each use. This prevents air exposure which can dry out the product and protects the crayon tip from damage.n* Hygiene: To maintain product hygiene and prevent bacterial transfer, avoid touching the crayon tip directly with unwashed fingers. For professional use or if sharing, gently wipe the tip with a clean tissue or lightly sanitize with a makeup-safe cleaner before each application.n* Sharpening: As a twist-up crayon, traditional sharpening is not typically required. If the tip loses its precise shape over time, gently shaping it against a clean tissue or a specific cosmetic crayon sharpener (if it has a compatible size) can help. Info needed: Confirm if it's a twist-up crayon or requires a sharpener.
