Allow to absorb then follow with a moisturiser. We recommend Advanced Night Restore which is specifically designed to be used after vitamin A.\u003c\/p\u003e\u003cp\u003eStep 2: For new users of Crystal Retinal, phase application in gradually. Use twice a week for the first 2 weeks, every other night for the next 2 weeks, then every night. You should always use a sunscreen the next morning after using vitamin A.\u003c\/p\u003e\u003cp\u003eNOTE: Ladder up your visible age-defying results over time with Crystal Retinal's 5 progressive strengths (0.01% - 0.1% retinaldehyde) - only available at Medik8. For those with very sensitive skin, we recommend starting with Crystal Retinal 1 (0.01%). However, most Crystal Retinal and vitamin A beginners start on Crystal Retinal 3 (0.03%). If you're an experienced vitamin A user already, start at Crystal Retinal 6 (0.06%) before working your way up to Crystal Retinal 10 (0.1%).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSafety Warning:\u003c\/strong\u003e Avoid eye area.
