Korean Retinal 101: What It Is, How to Start Without Purging, and Which Products to Try (2026)

Per SGC's formula check, Korean brands favor retinal (retinaldehyde) over retinol because the conversion to retinoic acid is one step shorter — meaning faster results at lower concentrations and, when formulated well, less of the peeling and purging that drives people away from vitamin A entirely. Here's what's different, how to start safely, and which products are worth the investment.
