Crystal Retinal
Retinal SerumMedik8 Crystal Retinal is an advanced vitamin A serum designed to deliver remarkable anti-aging results. It contains retinaldehyde, a potent derivative of vitamin A that is one step closer to retinoic acid than retinol, making it faster-acting and more effective while remaining gentle on the skin. The serum works overnight to visibly diminish fine lines and wrinkles, refine skin texture, and even out skin tone. It also helps to reduce the appearance of blemishes and hyperpigmentation, promoting a clearer, brighter, and firmer complexion. The unique crystal encapsulation system ensures the retinaldehyde is released gradually, minimizing irritation and maintaining its stability and potency. Available in a progressive ladder of strengths, it allows users to gradually increase their vitamin A dosage as their skin builds tolerance.

Oriva Scientific Assessment
Contains retinaldehyde, a highly effective form of vitamin A that converts to retinoic acid in one step, making it faster and more potent than retinol. This active ingredient stimulates cell regeneration, boosts collagen production, and inhibits melanin production, leading to smoother, firmer, clearer, and more even-toned skin. The crystal encapsulation technology ensures stability and a slow release for reduced irritation.
Target User: Individuals looking to address signs of aging (fine lines, wrinkles), improve skin texture, reduce hyperpigmentation, or manage acne. Suitable for those who have built tolerance to lower-strength retinoids or are ready to start with a potent vitamin A.
Avoid If: Pregnant or breastfeeding individuals. Those with extremely sensitive skin should approach with extreme caution, starting with the lowest strength (CR1) and introducing very slowly. Individuals new to retinoids should also start with CR1.
Avoid / caution

- Breastfeeding
- Very sensitive skin (without careful introduction)
- Individuals new to retinoids (start with CR1)
