A guide to atomu Korean skincare
Atomu is a Korean skincare brand that builds a routine around essences, with a cleanser, two moisturizers, and a targeted serum filling out the rest. This collection carries the atomu line we stock, so here is how the pieces fit together and how to pick between the essences and sizes.
How atomu approaches a routine
Atomu leans on essences as the heart of its routine rather than a single hero cream. The collection carries the Original Essence plus the A and B variants, which means you can layer light hydration in the step between cleansing and moisturizer. Around those essences the brand offers one cleanser, two moisturizers, and a serum, so it covers a full routine without a sprawling catalog.
The essence range
The essences are the core of the line. The Original Essence comes in 20ml, while Essence A is 20ml and Essence B comes in both 20ml and 50ml. There is also a standalone Essence 50ml. The 20ml sizes are the easy way to try a variant before committing, and the 50ml bottles are the value pick once you know which essence your skin likes. Apply an essence after cleansing, pressing it in before your moisturizer.
Acris Foam Cleanser
The Acris Foam Cleanser 120ml is the first step in an atomu routine. As a foam cleanser it lifts away sunscreen, makeup residue, and the day's grime, then rinses clean so your essences and serums can absorb. Use it morning and night, or just at night if your skin runs dry.
Acris Serum
The Acris Serum is atomu's targeted treatment step, and it comes in a 10ml trial size and a 30ml full size. A serum is more concentrated than an essence, so it sits after your essence and before your moisturizer. The 10ml is a low-commitment way to see how your skin responds before moving to the 30ml bottle.
Lotion 17 and Cream 17
Atomu splits its moisturizer step into two textures, both 100ml. The Lotion 17 is the lighter, more fluid option that suits oily or combination skin and warmer weather. The Cream 17 is the richer choice for dry skin or colder months when you want more cushion. Pick one as your sealing step, or keep both and switch with the seasons.
Layering the atomu line
A full atomu routine reads cleanser, essence, serum, then moisturizer. Start with the Acris Foam Cleanser, press in an essence, follow with the Acris Serum where you want a stronger treatment, and seal with the Lotion 17 or Cream 17. You can run a lighter version too: cleanser, one essence, and a moisturizer covers the basics on a quick morning.
Matching atomu to your skin type
Your skin type mostly decides the moisturizer. Oily and combination skin tend to do well with the Lotion 17, while dry and mature skin prefer the Cream 17. The essences are light and layerable, so most skin types can use them; if your skin is very dry, lean on the richer cream to seal everything in at the end.
Sizes and value
Atomu sells most products in a small trial size and a larger full size, which makes the line easy to sample. The essences run 20ml and 50ml, the Acris Serum 10ml and 30ml, the moisturizers 100ml, and the cleanser 120ml. Buy the small size to test a product, then size up to the larger bottle for better value once it earns a spot in your routine.
Authenticity and sourcing
Everything in this collection is genuine atomu stock that ships from Korea, and the listing is filtered to what is in stock, so the count reflects what can ship now rather than the brand's full catalog. You are buying the real Korean retail products.
