What it is

Part of the vitamin A family

Retinoids are a family of vitamin A ingredients. Skin converts retinol into retinal, and retinal into retinoic acid, the form skin actually uses. Because retinal is one step closer, it is often described as faster-acting than retinol at the same strength.

K-beauty brands pair it with soothing and hydrating partners like peptides, panthenol or centella, and in 2026 you will see it in shots, boosters and night serums.

  • Retinol, then retinal, then retinoic acid
  • Usually used at night
  • Often paired with soothing ingredients

Night shift for your skin

What brands typically recommend

Starting retinal the gentle way

  1. 01

    Start a few nights a week

    Most brands suggest 2–3 nights a week at first, building up as your skin gets used to it.

  2. 02

    Use a small amount

    A pea-sized amount for the whole face is typical.

  3. 03

    Moisturize after

    A barrier cream on top helps keep skin comfortable.

  4. 04

    Sunscreen every morning

    Retinoids can make skin more sensitive to the sun, so daily SPF matters.
