use Retinal before they deepen!

fewer steps than retinol, while offering a milder
alternative to traditional retinoids.

How To Use

Retinal mask
that melts into the skin

See the hydrogel gradually
become more transparent
as it stays closely adhered to your skin.

After cleansing, refine skin texture with toner.
Open the package and remove the films
from the upper and lower face masks.

Apply the upper mask sheet
centering around the eyes, and the lower
mask sheet centering around the mouth
to fit your face.

Remove the mask once it becomes transparent
and pat the remaining essence onto the skin
to help it absorb.

* The degree and timing of transparency may vary depending on skin condition and the environment of use.
* 1–3 hours of use is recommended.

TIPS!

Applying the mask after completing
your entire skincare routine
(toner - serum - cream)
allows for even firmer skin care.

Detach the circular patches from the
eye and mouth cutouts
and apply them to specific areas
of concern for intensive care.
