    Questions and answers

    When does Medik8 go on sale?
    Medik8 discounts cluster around Black Friday, Cyber Monday and seasonal skincare events, plus occasional sitewide promotions on medik8.com. Retailers like Dermstore and Look Fantastic run their own sales on different dates, so the lowest price often moves between stores.
    Where is Medik8 cheapest?
    It varies by product and week. Medik8's own site rarely discounts but bundles and sets lower the per-item cost, while third-party retailers such as Dermstore, Look Fantastic and SkinStore discount single bottles more often. Check the price history on each product page to see which store has been lowest.
    Which Medik8 products are most popular?
    Crystal Retinal is the flagship line, and the numbered strengths (1, 3, 6, 10, 20) let you build tolerance gradually. CeraVe-style basics aside, the brand's other staples are the C-Tetra vitamin C serum and the Hydr8 B5 serum. Bakuchiol Peptides is the pick for anyone avoiding retinoids.
    What is the difference between Crystal Retinal 1 and Bakuchiol Peptides?
    Crystal Retinal 1 uses 0.01% encapsulated retinaldehyde, which is stronger and faster-acting than retinol but still the entry step of the ladder. Bakuchiol Peptides uses bakuchiol, a plant-derived retinol alternative, and is suitable for sensitive skin and pregnancy. Neither should be layered with strong acids in the same routine.
    What is Medik8's return policy?
    Orders from medik8.com can be returned within 30 days if unused and in original packaging, and the brand covers faulty items. Returns from third-party retailers follow that store's policy, which is often shorter, so confirm before buying elsewhere.
    Are there Medik8 discount codes?
    Deal.ai doesn't list Medik8 discount codes. It checks what Medik8 products actually cost at every store, so a real markdown shows on this page as a deal as soon as it starts, and each product's page has its price history to tell a sale from its usual price.
