Retinization
Also called: Retinoid adjustment, Retinol adjustment
Retinization is the adjustment period when skin adapts to a retinoid, often with temporary dryness, flaking, stinging, or redness.
At a glance
- Mild flaking can happen when starting retinol or prescription retinoids.
- Burning, cracking, swelling, or severe peeling is irritation, not a badge of progress.
- Moisturiser, lower frequency, and fewer other actives usually make retinization easier.

The short answer
Retinization is the adjustment phase when your skin gets used to retinol or another retinoid.
It can show up as dryness, flaking, redness, stinging, or peeling. Retinoids are well studied for skin aging, acne, and texture, but irritation is a known practical issue[1].
How to use the word
Retinization does not mean "push through anything."
Mild dryness is common. Raw skin is a stop sign.
Retinoids work by influencing skin-cell behaviour and renewal pathways[2]. That is why the skin needs time to adapt. It is also why using retinol every night from day one often ends with flakes and regret.
Mads's practical read
If retinization is mild, slow down and moisturise.
If it burns, cracks, swells, or keeps getting worse, pause. A good retinoid routine should be calm enough to repeat, not dramatic enough to make you fear your bathroom shelf.

Common questions
Is retinization the same as purging?
No. Retinization describes irritation and adjustment signs such as dryness and flaking. Purging describes acne lesions surfacing faster in acne-prone areas.
How do I reduce retinization?
Use retinoids less often, moisturise, avoid acids on the same night, and restart only when your skin feels calm.
