Keauty guide · Cushion makeup
Shade numbers are useful clues, not a guarantee. Use undertone, depth, daylight and a small test to make a Korean cushion choice more reliable.
Short answer
Start with the closest depth you can verify in daylight, then use the letter or shade name to refine undertone.
Start with the closest depth you can verify in daylight, then use the letter or shade name to refine undertone. A 21 or 23 label is not a universal global shade standard, and a product page cannot replace a real swatch test.
Keauty's rule of thumb: treat the shade label as a starting hypothesis, not a promise of a perfect match.
What do Korean cushion shade numbers mean?
Numbers such as 17, 19, 21, 23 and 25 usually communicate relative depth within one brand's range. They do not behave like a single international scale. A 21 in one formula can look different from a 21 in another because pigment, finish, oxidation, lighting and the brand's intended market all vary.
Use the letter or shade name as a second clue
Some lines add letters such as C, N or W; others use names such as Ivory, Linen, Beige or Ginger. These labels can suggest cool, neutral or warmer direction, but they are still brand-specific. Compare shades within the same line first, and do not assume that a name like ‘natural’ means neutral on every complexion.
Depth comes before undertone
If the base is visibly too light or too deep, a perfect undertone will not rescue the match. Hold the shade near the jaw rather than relying only on the back of the hand. For online shopping, compare the brand's own shade photos and product wording, then choose the closest depth with the least dramatic jump.
Examples from Keauty's current cushion catalogue
Keauty's catalogue includes lines with different naming systems. Clio Kill Cover Founwear currently lists 19C Light, 19N Porcelain, 21C Lingerie, 21N Linen and 23N Ginger. Hera Black Cushion lists 17N1 Ivory, 21N1 Vanilla, 23N1 Beige and 25N1 Amber. These are useful examples of how labels are structured, not a universal conversion chart.
A realistic online-shopping scenario
Imagine Lina usually wears a neutral-light base but is between two shades in a new cushion. Instead of choosing the prettiest compact, she checks the brand's shade photo, compares 19N and 21N at jaw depth, and looks for a retailer image taken in neutral light. If she cannot see a meaningful difference, she chooses the option with the safer depth and confirms the return policy before opening the product.
Illustrative scenario
A practical way to make the decision
Imagine Lina usually wears a neutral-light base but is between two shades in a new cushion. Instead of choosing the prettiest compact, she checks the brand's shade photo, compares 19N and 21N at jaw depth, and looks for a retailer image taken in neutral light. If she cannot see a meaningful difference, she chooses the option with the safer depth and confirms the return policy before opening the product.
This is an illustrative example, not a real customer or a documented product outcome.
A simple way to use this guide
Keep the test small, make one decision at a time and record what you actually observed rather than what a product number promises.
- Compare depth near the jaw, not only the hand.
- Read the brand's letter or shade name as an in-range clue.
- Check the shade in neutral daylight and on an unfiltered screen.
- If possible, test a small amount and wait for the finish to settle before judging.
Application and safety notes
- Follow the product's own instructions and use it only as intended.
- Introduce one new variable at a time when your skin or makeup routine is changing.
- Stop if you develop persistent burning, swelling, blistering or another clear reaction.
- Seek professional advice for persistent or severe symptoms.
Quick comparison
| Signal | What it tells you | What it does not prove | Best next step |
|---|---|---|---|
| 19C / 19N | Very light range | C or N is brand-specific | Verify the brand swatch |
| 21 | Light-to-medium range in many lines | Often several undertone options | Compare jaw depth |
| 23 | Medium range in many lines | Names vary widely | Check warmth in daylight |
| 25 | Deeper option in some lines | Not a universal depth | Use the product's own photos |
Common follow-up questions
What readers usually ask next
Is 21 always the safest Korean cushion shade?
No. 21 is common, but the actual depth and undertone vary by brand, formula and finish.
What is the difference between C and N?
Often C suggests a cooler direction and N a neutral direction, but the letters are not a regulated standard. Confirm them against the brand's own shade descriptions.
Should I match my hand or my face?
Use the jaw or lower cheek as the more relevant reference. The hand can be a different colour from the face.
Can I trust a shade shown on my phone?
Use it as a clue only. Screen brightness, colour settings and photography lighting can shift the appearance.
What if I am between two shades?
Compare depth and undertone in daylight, choose the smaller visible mismatch, and confirm the retailer's return conditions before opening the item.
Tilda's choice
Choose the option you can evaluate clearly
For most readers, the best choice is the one that matches the routine they can follow consistently and the evidence they can actually verify—not the option with the strongest marketing language.
