Does the 0.5 in the name mean 0.5% retinol?

Yes. The official ingredient declaration identifies the formula’s retinol concentration as 0.5%.

Is this a good choice for a retinol beginner?

It is positioned for people already familiar with retinol. COSRX directs beginners and sensitive-skin shoppers seeking a gentler introduction toward The Retinol 0.1 Cream.

How often should I use it when starting?

Begin at night two or three times per week. The package directions say to increase gradually to every other night only as your skin tolerates it.

Should moisturizer go before or after the retinol oil?

In the standard routine, moisturizer follows the oil. If your skin is sensitive, COSRX also suggests applying moisturizer first as a buffer and placing the oil on top.

What kind of texture does the oil have?

It has a silky oil texture with squalane and vitamin E forms in the formula.

Do I need to wear sunscreen while using it?

Yes. Apply sunscreen during the daytime while using this retinol oil.

How soon should I finish the bottle after opening it?

COSRX recommends using it within three months after opening.

0.5% pure retinol

Smoother-looking texture

Silky oil feel

Main active: Retinol
Intensity: Standard

PRODUCT DETAILS

This is 0.5% pure retinol in a silky face oil, made for your routine once you have some experience with retinol. It offers an intermediate-level option for visible fine lines, loss of firmness and uneven-looking texture.

Its focus is clear: soften the look of fine lines and help rough texture look smoother. The retinol-led care also supports firmer-looking skin and addresses the appearance of uneven tone.

This is an oil, not a serum. Squalane leads the formula and is valued as an emollient for helping skin feel soft and moisturized. Along with the documented silky texture, it gives this retinol step a softly conditioned feel.

Although it can suit all skin types, it is best suited to a routine already comfortable with retinol. If you’re new to retinol, or your skin is sensitive, The Retinol 0.1 Cream is the gentler starting option in the line.
