AHC Youth Focus Essence 30ml $13.20 + Delivery ($0 with OnePass) @ Catch

Spotted this as part of the 40% off Catch Sale. This product contains 0.05% retinal or retinaldehyde, which requires one less conversion step to retinoic acid (the active form) compared to retinol. 0.05% retinal is a pretty decent percentage that is suitable for intermediate retinoid users (i.e. not beginners). I have no idea how old Catch's stock is, but at this price it's worth a gamble. Usually South Korean products have an expiry date printed on them.

AHC is a well-established South Korean skincare company and their eye creams have been bestsellers for many years there. Their product lines are vastly different outside South Korea, but this one does seem to be sold in their local market too. Retails at Myer for $79.
