At the core of our brand is a commitment to clean beauty. By using pure, safe, plant-derived ingredients, we stand against animal testing while prioritizing transparency for our valued customers.

ONE THING began by creating a range of tailored single-ingredient formula toners to address individual skin concerns.

Until now, ONE THING has been questioning the high price of cosmetics. We found out that 90% of the price of cosmetics goes to marketing and packaging. That's we've taken a different approach. At ONE THING, we focus on providiing our customers with high-quality ingredients that are not only effective but also affordable. With a commitment to transperancy, we offer products that are free from harmful ingredients, vegan and are never tested on animals. We advocate for consumers' right to know and support rational consumer spending. Join us in our pursuit of better, more affordable skincare and see the difference ONE THING can make for your skin.

FAQs

If you are a K-Beauty beginner, we recommend starting with a simple 4-step routine that includes a cleanser, a serum, a moisturiser, and a sunscreen. We recommend starting small because if your skin is not used to many actives and layering, the sudden introduction of a 10-step routine that contains powerful products may overwhelm your skin, or cause it to break out. Slowly increasing the number of products in your routine will also make it easier for you to determine if a product is not suitable for your skin.

Start by identifying your skin type—dry, oily, combination, or sensitive.

  • For dry skin: look for hydrating ingredients like hyaluronic acid, ceramides, and squalane.
  • For oily/acne-prone skin: opt for lightweight, non-comedogenic formulas with tea tree, salicylic acid, or niacinamide.
  • For sensitive skin: go for fragrance-free, soothing products with centella asiatica or heartleaf.We also have a skin-type filter on our shop to help you choose easily!

The 10-step routine is a popular K-beauty method focused on hydration, protection, and gradual improvement. It includes:

  1. Oil Cleanser
  2. Water-Based Cleanser
  3. Exfoliator
  4. Toner
  5. Essence
  6. Serum/Ampoule
  7. Mask
  8. Eye Cream
  9. Moisturiser
  10. Sunscreen (AM) or sleeping pack (PM)
    You don’t have to do all 10 steps daily just choose what works best for your skin.

Korean skincare tends to focus more on prevention, hydration, and gentle layering, while Western skincare often emphasizes quick results and active ingredients. K-beauty also leans toward natural extracts, innovative textures, and routines tailored to long-term skin health.

Snail mucin is a hero ingredient in K-beauty! It's rich in glycoproteins, hyaluronic acid, and zinc, helping to improve hydration, fade dark spots, and boost skin regeneration. It’s especially beneficial for skin that's dull, scarred, or uneven in texture.
