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!)

Applying products in the correct order helps maximize absorption and results. Here’s the ideal K-beauty routine order:

  1. Oil-based cleanser (removes sunscreen & makeup)
  2. Water-based cleanser (cleanses leftover impurities)
  3. Toner (hydrates & preps your skin)
  4. Essence or Ampoule (targets specific concerns) Anti-aging, Dark spots ... etc
  5. Serum (concentrated active ingredients)
  6. Moisturizer or Cream (locks in hydration)
