Ingredient intelligence

Meet the ingredient

Retinol is a well-researched derivative of vitamin A and one of skincare’s most established ingredients for visible signs of ageing.

Once applied, it is converted by the skin into active retinoic acid through a two-step process. This allows it to support skin renewal, improve uneven texture and promote a firmer, smoother-looking complexion.

Why TOTOKA selects it

Few cosmetic ingredients offer the same combination of benefits as retinol. It targets fine lines, loss of firmness, uneven texture, blemishes and post-blemish marks within one well-structured routine.

Its performance can be significant, but consistency and gradual introduction are essential for maintaining skin comfort.

INGREDIENT SNAPSHOT

What it brings to your skin

The essential information, without the ingredient overload.

Retinol supports the skin’s natural renewal process and helps reduce the buildup of dead skin cells. It also encourages the processes associated with collagen production, improving the appearance of fine lines, texture and firmness over time.

Its renewing action can additionally help keep pores clearer and gradually improve uneven tone and post-blemish marks.

Routine placement

Where it fits

Follow with moisturiser and use broad-spectrum sunscreen every morning. Avoid applying retinol to irritated or compromised skin.
