How should you use a Vitamin C serum in your routine?

For maximum skin health and radiance, a simple yet powerful 4-step morning routine is highly recommended. Consistently following these steps ensures your skin is cleansed, treated, hydrated, and shielded from environmental stressors throughout the day:

Cleanser: Start with a gentle, pH-balanced wash like Keyci Cleanser to remove overnight impurities.

Vitamin C Serum: Apply a high-potency antioxidant like Keyci Vitamin C Serum to brighten and even out skin tone.

Moisturizer: Lock in hydration with a lightweight barrier repair moisturizer.

Sunscreen: Finish with a broad-spectrum SPF 50 to prevent UV damage and photo-aging.

Does pairing Vitamin C serum with sunscreen improve skin protection?

Yes, this is a scientifically proven strategy that many people underestimate. While sunscreen shields the skin from UV rays, Vitamin C acts as a secondary line of defense by neutralizing free radicals that "leak" through. When you pair a brightening serum with a high-protection sunscreen like InvisiBlock, you significantly improve overall skin defense, prevent hyperpigmentation more effectively, and boost the efficacy of your SPF.
