Skincare 101: What to Know Before You Glow - FAQ
K-beauty products are known for their gentle, effective formulas powered by natural ingredients, cutting-edge science, and a prevention-first philosophy. They focus on long-term skin health, hydration, and barrier repair — instead of harsh actives and quick fixes. At Lakinza, we curate only the most trusted K-beauty brands that deliver real results for all skin types.
Great skin is a journey, not a sprint. Most people begin to notice changes like improved hydration or smoother texture in 2–4 weeks with consistent use. For concerns like acne scars, dark spots, or anti-aging, you may see best results after 6–8 weeks. Results vary based on skin type, product type, and usage consistency.
Pro tip: Stick with your routine daily and give each product time to work — no skipping!
To get glowing, healthy skin:
- Double cleanse (especially at night) to remove makeup, sunscreen, and buildup
- Apply products in the correct order: cleanser → toner → serum → moisturizer → SPF
- Be consistent — morning and night!
- Use sun protection daily (yes, even in Canada!)
