Skincare 101: What to Know Before You Glow

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!)

 Need a routine tailored to your skin? Click here to get free skincare advice.

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)

I'm so

I’m glad I found a store that carries Korean products. I recently moved to Halifax, Canada, and I’m really happy because I love these products, which I’ve been using for quite some time. Thank you, your delivery system is very professional and the product selection is amazing.

Wow—I’m truly blown away by my shopping experience at Lakinza!

I actually came across your website by accident, but the competitive prices, wide product selection, and helpful “how-to” guidance convinced me to purchase all my products from your site. My order arrived in pristine condition, perfectly packaged with care, and delivered within just a couple of days.

And now, having this personalized information you’ve shared has made me not just a satisfied customer, but a loyal fan of Lakinza. Thank you again for going above and beyond!

Amazing Service & Fast Shipping!

I’m so impressed with Lakinza! I placed my order last night and within 12 hours it was already packed and on its way—seriously the fastest shipping I’ve ever experienced from an online beauty store. They have a great selection of K-beauty skincare and makeup at really reasonable prices. Similar or a bit less than at Olive Young and with much faster shipping! I’ll definitely be ordering again—this is my new go-to for Korean beauty products!
