Iaso

IASO is a Korean cosmetics brand that spans skincare and makeup rather than sticking to one category. The skincare side leans on the Yutsu line for hydration and barrier repair, while the makeup side covers eyes with a mascara, a penliner, and a drawing eyebrow pencil. It fits a shopper who wants both a care routine and everyday color from a single brand, instead of juggling several.

Yutsu is the core of IASO's skincare here, and it arrives as a small system. The Yutsu Mist 100ml refreshes and preps, the Yutsu Repair comes in both 30ml and 50ml so you can match the size to how often you reach for it, and the Yutsu Cream 50g seals everything in. Used together they read as a layered routine, with the mist first, the repair serum next, and the cream last.

The Yutsu Repair serum ships in two sizes, and the choice comes down to pace of use. The 30ml is the lower-commitment way to try the formula or to keep in a travel bag, while the 50ml is the better value if it has already earned a daily spot in your routine. Both are the same serum, so start with the 30ml if IASO is new to you and size up once you know it works for your skin.

Beyond Yutsu, IASO carries care-focused pieces for a fuller routine. The Purifying Emulsion 100ml is a lightweight lotion-style step that adds moisture without a heavy finish, and the Exclusive Massage Treatment 250ml is a generous tub meant for a slower, hands-on session. The massage treatment in particular suits an at-home facial night rather than a quick morning routine.

IASO's color range here is built around the eyes. The Attractive Mascara Volume builds lash thickness, the Attractive Penliner 5g draws a fine liner line, and the Drawing Eyebrow Pencil shapes and fills brows. Together they cover a complete eye look from one brand, so you can build the whole look without sourcing each piece separately.

The Sun Shield Waterproof 70ml is IASO's sun step, and the waterproof claim points it toward humid days, sport, or time near water. Apply it as the last skincare step in the morning, after the Yutsu cream and before any makeup. A waterproof finish is the practical choice when sweat or swimming would otherwise break down a lighter sunscreen.

You can assemble a full day from IASO alone. A morning could run mist, Yutsu repair, Yutsu cream, then Sun Shield, finished with the eye trio. An evening could swap in the Purifying Emulsion or, once or twice a week, the Massage Treatment for a longer session. Layering thin to thick keeps each step working, with watery textures first and the cream last.

IASO is a Korean brand, and the catalog here lists a few dozen products across its skincare and makeup lines. Because the range mixes care and color, the best approach is to pick the job you want filled first, whether that is a Yutsu repair routine or the eye makeup set, then add the sun and treatment pieces as your routine grows.
