Review: Medik8 C-Tetra Advanced has become one of my go-to morning serums. I love that it delivers all the brightening benefits of vitamin C without the irritation or heaviness that stronger formulas can sometimes cause. The texture is a lightweight gel-serum that absorbs quickly and layers beautifully under moisturizer and SPF—no stickiness, no pilling. Within a couple of weeks of consistent use, my skin looked noticeably more radiant and balanced. I also noticed a subtle plumping effect, especially through the cheeks, and my skin felt well-hydrated throughout the day. It gives that healthy, lit-from-within glow rather than an artificial shine. What really sets this serum apart for me is how gentle yet effective it feels. Even with daily use, my skin barrier stayed calm and happy, which isn’t always the case with vitamin C. It’s a great option if you want visible brightening, hydration, and antioxidant protection without compromising comfort. Overall, Medik8 C-Tetra Advanced feels like a smart, elevated vitamin C—perfect for everyday use and especially great if your skin prefers a more balanced, modern formulation.

I emailed the company back about a year ago and this is what they told me. I’ve switched to a very similar one from ghost democracy that is 18% THD and doesn’t have the fragrance/essential oils because that was irritating my skin. It has the same dry oil like texture as medik8 **Q: Es duradera oh tiene corto tiempo de vida ,ocea se oxida rapido?o** A: Esta bueno ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by T***P on 3 January 2026* Medik8 C-Tetra Advanced has become one of my go-to morning serums.

My skin is much softer and I need hardly any moisturiser after 4 months of use. I've recommended it to my sister and son, who both suffer from very dry skin on their face and they saw an immediate improvement. I use 4 drops every morning and use Medik8 Retinol 3TR every other evening. I love it! ## Frequently Bought Together - Medik8 C-Tetra - Brightening, Balancing, Plumping Daily Vitamin C Face Serum - Firms and Smooths Fine Lines and Wrinkles - With Squalane - 1.0 oz - Medik8 Crystal Retinal 3 - Brightening, Firming, Advanced Skin Retinaldehyde Serum - Smooths Wrinkles - Hyaluronic Acid, Glycerin, Vitamin E - 1 oz - Medik8 Liquid Peptides - Regenerating Multi Peptide Serum - Smooths Wrinkles and Fine Lines - Hydrating, Brightening, Plumping - 1.0 oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.pa/products/254168391-c-tetra-30ml](https://www.desertcart.com.pa/products/254168391-c-tetra-30ml) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-05-18*
