In a world of overwhelming skincare advice, simplicity backed by science is a breath of fresh air. That’s exactly what Medik8 delivers with its renowned CSA Philosophy—a streamlined, effective routine designed to fight premature skin aging using three core pillars: Vitamin C + Sunscreen by day, and Vitamin A by night.
Whether you’re a skincare beginner or looking to refine your regimen with powerful, targeted solutions, this step-by-step guide will help you build your perfect CSA routine using Medik8’s expertly formulated products.
Step 1: Cleanse & Prep Your Skin (AM & PM)
Before applying any active ingredients, it’s essential to begin with a clean, balanced canvas.
- Morning: Use Gentle Cleanse™—a mild, sulfate-free foaming cleanser perfect for all skin types.
- Evening: For a deeper cleanse, opt for Surface Radiance Cleanse™, which includes mandelic and lactic acid to lightly exfoliate and brighten dull skin.
Follow with Press & Glow™, Medik8’s PHA-based toner, which hydrates while encouraging daily cell turnover—preparing your skin for maximum ingredient absorption.
Step 2: Apply Vitamin C in the Morning
Vitamin C is your skin’s daytime defender. It protects against free radical damage, brightens skin tone, and stimulates collagen production.
- Choose: C-Tetra® for beginners, C-Tetra Luxe™ for dry or dull skin, or Super C Ferulic™ for experienced users seeking maximum antioxidant power.
Apply a few drops to clean, dry skin and gently press into the face and neck. This step builds a strong foundation for healthy, glowing skin over time.
Step 3: Lock In Hydration & Moisture
Moisturizing is essential for maintaining skin barrier function, especially when using potent actives.
- Morning: Try Daily Radiance Vitamin C™, which combines lightweight hydration with SPF 30 for daytime protection.
- Evening: Use Advanced Night Restore™, packed with ceramides and peptides to repair and replenish the skin overnight.
If you have particularly dry or sensitive skin, layer Hydr8 B5™ serum underneath your moisturizer for an extra hydration boost.
Step 4: Apply Sunscreen Every Morning
No CSA routine is complete without daily sun protection. UV damage is the top contributor to premature aging, and your Vitamin C works best when paired with a broad-spectrum SPF.
- Use: Advanced Day Ultimate Protect™—a high-performance moisturizer with SPF 50+ PA++++, blue light protection, and DNA repair enzymes.
Apply as the last step in your morning routine, at least 15 minutes before sun exposure. Don’t forget your neck and décolleté!
Step 5: Apply Vitamin A at Night
Vitamin A (retinoids) is the cornerstone of any anti-aging skincare routine. It increases cell turnover, smooths fine lines, and fades pigmentation for a clearer, firmer complexion.
- Beginner? Start with Crystal Retinal 1™ or Crystal Retinal 3™.
- More experienced? Step up gradually to Crystal Retinal 6™, 10™, or even 20™ as your skin builds tolerance.
Apply your chosen Crystal Retinal product after cleansing and before moisturizing. Start with 2–3 nights a week, then increase frequency as your skin adjusts.
Bonus: Weekly Treatments
In addition to your core CSA steps, consider integrating weekly treatments for enhanced results:
- Sleep Glycolic™ – an at-home AHA peel that refines skin texture overnight.
- Ultimate Recovery™ Intense – a calming balm perfect for post-retinoid care or after professional treatments.
