Thank you.** A: Yes, Crystal Retinal 3 is suitable for everyone new to Retinaldehyde (Retinal). When first using Crystal Retinal, we recommend following our gradual phase-in method: use twice a week for the first 2 weeks, every other night for the next 2 weeks, then every night. You should always use sunscreen in the morning while using vitamin A. **Q: I am currently using ha serum + niacinamide serum + moisturiser after applying a low strength retinol. is that the correct order for this product too?** A: Hi There, Thanks for your question. We would recommend layering products from lightest to heaviest in texture for optimum penetration. So water-based products would go on the skin first, then oil-based serums, then emulsion serums and moisturisers last. I would recommend following the layering order below: 1. Cleanse 2. Hyaluronic acid serum 3. Retinol 4. Niacinamide serum (if it's an emulsion if a water-based serum use it before retinol serum) 5. Moisturiser I hope this helps and if you have any other questions please do not hesitate to get back in touch. **Q: Is this item genuine or Fake? I did not receive any instructions in the box ?** A: This item does not come with any application instructions in the box, but we can advise has been fulfilled by Medik8 and is a genuine item. How to Apply: Use in the evening. First cleanse, then apply 2 pumps of Crystal Retinal over face and neck. Allow to absorb then follow with a moisturiser. We recommend Advanced Night Restore, designed to be used after vitamin A. Phase-In: 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 in the morning while using vitamin A.
