Description

Introducing COSRX The Retinol 0.5 Oil: a concentrated pure retinol oil with zero water or derivatives. Formulated for those who have built retinol tolerance but want more impact—targeting loss of elasticity, deep-set lines, and uneven skin texture.

The oil is deceptively lightweight: a few drops glide over skin, absorbing instantly without stickiness. Use it at night after cleansing, before moisturiser. Build up gradually—twice a week to start, then increase as your skin adjusts.

Clinical results (4-week study):

• 22.02% reduction in forehead wrinkles
• 18.40% improvement in nasolabial folds
• 17.68% decrease in crow’s feet
• 14–17% boost in skin elasticity (external & internal)

Pores tighten in 2 weeks: volume drops 48.87%, pore area shrinks 45.74%. The result? Firmer, smoother, more luminous skin. Make it your nightly ritual.
