Brand Comparison
Slip vs COSRX
A head-to-head comparison of two popular K-beauty brands. Which one is right for your skin?
Our Pick
COSRX
Higher editor rating (9 vs 8)
Slip
Slip is a silk pillowcase company, not a skincare brand in the formula sense — but mulberry silk genuinely reduces friction on sleeping skin and hair, which means less creasing, less breakage, and less pillow-imprinted cheek in the morning. The eye masks are what you want for long-haul flights.
Pros
- ✓ Legitimate friction-reduction benefit
- ✓ Gentle on lashes and extensions
- ✓ Aesthetic eye masks
Cons
- ✗ Not a skincare product per se
- ✗ Premium pricing
- ✗ Requires hand-washing
COSRX
The gateway brand for most people entering K-beauty, and for good reason. COSRX consistently delivers effective, no-frills products at prices that make most Western alternatives look overpriced. Their snail mucin line and BHA products are genuine category leaders. They rarely innovate, but they execute the basics exceptionally well.
Pros
- ✓ Outstanding value across the entire range
- ✓ Short, transparent ingredient lists
- ✓ Consistently effective formulations
- ✓ Widely available globally
Cons
- ✗ Packaging is utilitarian, not luxurious
- ✗ Rarely pushes boundaries with new ingredients
- ✗ Some products have a faint tea tree scent
