Medik8 Crystal Retinal 1 - 30ml

Start by using it twice a week for the first two weeks, then every other night for the next two weeks, and finally every night as your skin tolerates. Always use it as part of your evening skincare routine.

Yes, Crystal Retinal 1 (0.01% retinaldehyde) is specifically formulated as the introductory strength for very sensitive skin types or those new to vitamin A, thanks to its gentle encapsulation technology.

Retinaldehyde is a more potent form of vitamin A than retinol, clinically proven to act 11 times faster. It requires fewer conversion steps in the skin to become retinoic acid, leading to quicker and more visible results with reduced irritation.

Only consider progressing to a higher strength (like Crystal Retinal 3) once your skin has fully adapted to Crystal Retinal 1, and you've comfortably finished at least one or two tubes without any signs of irritation or sensitivity.

It is generally recommended to use Vitamin A products in the evening and Vitamin C products in the morning. For other strong actives like AHAs or BHAs, it's advisable to alternate nights or consult a skincare professional to avoid over-exfoliation or irritation, especially when first introducing Crystal Retinal.

While individual results may vary, clinical studies (based on Crystal Retinal 6) showed visible reductions in wrinkles and dark spots by 20% with just one tube. Consistent use is key to achieving optimal results.

This is a common adaptation period when starting retinoids. Reduce usage frequency to every other night or even every third night. Ensure your skin is well-hydrated with a rich moisturizer. If irritation persists, temporarily stop use and reintroduce slowly at a lower frequency.

Ensure consistent nightly use once your skin has adapted. If you've been using Crystal Retinal 1 comfortably for an extended period (e.g., finishing two tubes), consider gradually progressing to Crystal Retinal 3 for enhanced benefits, ensuring your skin remains comfortable.

Ensure the pump is fully primed by pressing it several times until product begins to flow. If it still doesn't dispense, gently tap the bottom of the bottle on a hard surface a few times to settle the product before trying to pump again.
