Ulos All

ULOS All-in-One moisturizers cover toning, hydrating, and moisturizing in one step. The collection of 30+ SKUs centers on two product types: Skin Milk and Skin Lotion, each available in 60ml travel size and 200ml full size. The Skin Milk has a slightly richer texture suited to normal and dry skin; the Skin Lotion is lighter and works well for oily or combination skin including men's routines. Both eliminate the need for a separate toner and serum step, making ULOS a practical pick for a stripped-down routine.

ULOS All-in-One Moisturizers: Buying Guide

ULOS is a Japanese skincare brand whose product line is built around a single concept: replace multiple post-cleanse steps with one well-formulated moisturizer. The ULOS All-in-One collection on skinsli lists 30+ SKUs - two product types (Skin Milk and Skin Lotion), two sizes (60ml and 200ml), value sets combining both, and a Costco-format 200ml Oily Combination Men's Lotion. This guide covers what sets those products apart and how to choose the right one.

What does ULOS All-in-One mean in practice?

An all-in-one moisturizer is formulated to perform the work of a toner, emulsion, and light moisturizer in a single application. After cleansing, you apply one product and proceed directly to sunscreen or makeup - no separate toner step, no serum unless you choose to add one. ULOS achieves this by combining humectants that mimic toner-level hydration absorption with emollients that provide the finishing layer a standard emulsion would add.

The trade-off is that all-in-ones are less targeted than a layered system. If your skin has a specific concern that responds to an active serum - a prescription retinoid, a high-dose vitamin C - you would still add that separately. For days when you want a faster morning routine or need a travel-friendly kit, the ULOS single-product approach works well.

ULOS Skin Milk versus Skin Lotion: key differences

The All-in-One Moisturizer Skin Milk has a milky, slightly thicker consistency. It spreads easily but leaves a light film that adds more surface moisture than the lotion version. Normal to dry skin tends to prefer the Skin Milk because the film helps retain water through the day, particularly in dry or heated indoor environments.

The All-in-One Moisturizer Skin Lotion is a thinner, more fluid texture. It absorbs faster and leaves less of a post-application feel, which suits oily or combination skin and those who dislike any residual film. The Costco-labelled 200ml Skin Lotion (Oily Combination Man All-in-One) is specifically positioned for men's routines and oily skin but uses the same lotion base with minor fragrance and finish adjustments.

Choosing between 60ml and 200ml: travel versus daily use

The 60ml size of both Skin Milk and Skin Lotion is a practical entry point. At roughly one pump per application, 60ml lasts approximately four to six weeks for one user applying once or twice daily. It fits within airline carry-on liquid limits and is compact enough for a gym bag or desk drawer. This is the format to start with if you have not tried ULOS before.

The 200ml size is more economical per ml for daily home use. The All-in-One Moisturizer Skin Milk 200ml+60ml set and the Skin Lotion equivalent give you both sizes in one purchase - the 200ml stays at home and the 60ml travels or goes to a second location. The 2-piece set and composite sets in the collection bundle both product types for routines that rotate between Milk and Lotion depending on season or skin condition.

ULOS value sets available in this collection

Several SKUs in the collection are bundle formats. The All-in-One 2-piece set of composite and the Jung Jiansheng All-in-one 2-piece set combine both Skin Milk and Skin Lotion in a single package - useful if you want to keep one formula for morning use and the other for a heavier evening application, or if you are comparing the two textures side by side before committing to one full-size refill.

The 200ml+60ml bundles for both Skin Milk and Skin Lotion are effectively a main-and-travel combination. Buy the 200ml+60ml Skin Milk bundle if you want both a home supply and a travel backup without buying two separate full-size bottles. These sets typically offer better value than two standalone purchases.

How to apply ULOS All-in-One Moisturizer correctly

Apply ULOS immediately after cleansing while skin is still slightly damp. Dispense three to five drops of Skin Lotion or one pump of Skin Milk into your palm. Press both palms together to warm the product, then press gently onto cheeks, forehead, chin, and nose rather than rubbing. This pressing motion seats the product into skin without disrupting the fresh-washed surface.

Allow 30 to 60 seconds before applying sunscreen or any additional product. ULOS is designed to absorb fully, so waiting a moment prevents pilling under SPF. In the evening, the same method applies - after cleansing and before sleep, the Skin Milk in particular provides enough occlusion for overnight recovery on most skin types without a separate night cream.

Where ULOS fits in a morning and evening routine

Morning: Cleanse, apply ULOS All-in-One (Milk or Lotion depending on skin type), then apply SPF. That is the complete morning routine if you are not using any actives. If you use a vitamin C serum or another targeted treatment, apply it between cleansing and ULOS.

Evening: Cleanse, apply any active treatment, then ULOS. Dry skin users may add a few drops of a face oil or a thin occlusives layer on top of Skin Milk in winter. The Skin Lotion is light enough that oily skin can use it as the last step without needing anything on top. The all-in-one concept is most efficient when you stop adding layers reflexively - test skipping the emulsion step for two weeks and observe whether skin stays balanced.

ULOS All-in-One for men's skincare routines

The ULOS Skin Lotion 200ml Oily Combination Man All-in-One (including the Costco label format) is explicitly designed for men's skin, which tends toward higher sebum output and faster absorption. The lotion texture avoids the greasy finish that puts many men off multi-step routines. Apply after shaving or after washing, and the one-step format keeps the routine under two minutes.

Men new to moisturizer often skip it because multi-product routines feel time-consuming. ULOS's single-step positioning solves that. The 200ml size lasts two to three months at daily use, making it a practical option for anyone who wants effective hydration without tracking multiple products.

FAQ

Frequently asked questions

  • skinsli lists 30+ ULOS All-in-One SKUs, covering Skin Milk and Skin Lotion in both 60ml and 200ml sizes, 200ml+60ml combination packs, 2-piece composite sets, and a dedicated Oily Combination Men's Lotion in 200ml.

  • Skin Milk has a milky, slightly richer texture suited to normal and dry skin. Skin Lotion is thinner, absorbs faster, and suits oily, combination, or men's skin. If you are unsure which to start with, buy the 200ml+60ml bundle - it includes both sizes in one format and lets you trial the one texture you chose while having the second available.

  • The 2-piece composite sets and the Jung Jiansheng 2-piece set in this collection bundle both Skin Milk and Skin Lotion together. This lets you use the richer Milk in the evening and the lighter Lotion in the morning, or compare both textures before committing to a full-size refill of one formula.

  • ULOS All-in-One products combine humectants for absorption-level hydration (similar to what a toner delivers) with emollient esters that provide the finishing film a traditional emulsion adds. This combination allows a single application to cover the toner, emulsion, and light moisturizer steps without layering separate products. The Skin Milk carries a slightly higher emollient ratio than the Skin Lotion.

  • ULOS Skin Lotion and Skin Milk formulas are generally low-irritant, but the Men's Oily Combination Lotion variant includes minor fragrance for finish. If you have fragrance sensitivity, the standard unisex Skin Milk or Skin Lotion is the safer choice. Check the ingredient list on the product page for the specific SKU you are ordering, as formulations can vary between the 60ml and 200ml versions and across set editions.

  • ULOS is formulated to replace toner, emulsion, and basic moisturizer - the three steps that follow cleansing in a standard Korean skincare routine. After cleansing, apply ULOS and proceed directly to SPF in the morning or to sleep in the evening. If you use an active serum (retinol, vitamin C, niacinamide), apply it between cleansing and ULOS. You do not need a separate toner or emulsion step when using ULOS as directed.

  • Yes. In the morning, apply after cleansing and follow with SPF. In the evening, apply after cleansing and any active treatment. Dry skin types may add a few drops of face oil on top of Skin Milk in winter for extra overnight moisture. Oily skin types generally find the Skin Lotion sufficient as a standalone final step in the evening without adding anything on top.

  • The Skin Lotion variant is specifically the lighter-texture option for oily or combination skin. The Costco-labelled Skin Lotion 200ml Oily Combination Man All-in-One is the most direct option for oily skin - it is formulated to avoid the greasy finish that heavier moisturizers leave. Oily skin users should use one pump or less and allow full absorption before applying SPF to prevent pilling.

  • For most dry skin types, the Skin Milk 200ml is sufficient on its own in humid climates or indoors. In cold, dry winters or for very dry skin, layering a few drops of a face oil or a sleeping mask on top of Skin Milk in the evening adds the extra occlusion needed. The all-in-one concept works best when you test it for two weeks and then decide whether to add a layer rather than layering by default from the start.
