DMCK Clean Arc Buying Guide: Ampoules, Cream, Mist, Sunstick, and Cushion
DMCK Clean Arc is a treatment-focused Korean skincare line centered on the Arc ampoule formula available in multiple concentrations and sizes. The range builds out from the ampoule core with a supporting cream, mist, and sunstick, and includes a cushion format that delivers the ampoule formula as a base or coverage product. This guide covers each product in the Clean Arc lineup and how to combine them by skin concern and routine preference.
What the DMCK Clean Arc line is and how it is structured
DMCK's Clean Arc system is organized around a single core formula - the Arc ampoule - available in escalating concentrations and sizes. The 10ml is the trial or targeted-use size; the 30ml is the standard daily treatment; the DI Original Ampoule 50ml is the large full-treatment format; and the Arc Ampoule Forte is the strengthened high-concentration variant. A supporting Clean Arc Cream, Mist, and Sunstick extend the same formula into moisturizer, spray, and UV protection formats. The Ampoule Cushion with Original Refill brings the Arc formula into a cosmetic coverage format.
With 11+ products across these categories, the Clean Arc line is designed to run the same Arc actives through multiple routine steps - from treatment ampoule through moisturizer and SPF, with an optional cushion for skin tone, all carrying the core Clean Arc formulation.
Choosing between the Clean Arc Ampoule sizes: 10ml, 30ml, and DI 50ml
The Clean Arc Ampoule comes in three sizes. The 10ml is a mini or trial size - practical for testing the formula before buying larger, or for travel. It provides roughly 2-4 weeks of daily use at a small drop per application. The 30ml is the standard ampoule size for daily use, providing 2-3 months for most people applying once or twice daily. The Clean Arc DI Original Ampoule 50ml is the largest standard format, extending the supply to 3-4 months for regular use - the better value for people who know they will use the ampoule consistently.
All three contain the same Clean Arc formula. Start with 10ml if you are new to the line; if the formula suits your skin, move to the 30ml for ongoing use or the DI 50ml for a longer supply at a lower per-ml cost.
Arc Ampoule Forte: the strengthened concentration
The Arc Ampoule Forte is the high-concentration variant of the Clean Arc ampoule formula. 'Forte' in skincare product naming typically signals a stronger or more concentrated version of an existing product - more actives per dose, or the same active at a higher percentage. This makes the Forte the step up for skin that has been using the standard Clean Arc Ampoule and wants a more intensive effect, or for people who prefer fewer concentrated doses over daily lighter applications.
The Forte is available in both a full-size 30ml and what appears to be an unlabeled size (Arc Ampoule Forte without a size specification - check the product listing for the current format). Introduce the Forte gradually if your skin is not accustomed to the standard ampoule first - higher concentrations can cause sensitivity on unprepared skin.
Clean Arc Cream 100ml: the moisturizer in the system
The Clean Arc Cream 100ml is a larger-than-usual face cream size for a Korean skincare line - most face creams come in 50ml. At 100ml it provides 3-5 months of daily use, making it a practical bulk size for a product you apply every day. The cream delivers the Clean Arc formula in a moisturizer format, providing the Arc actives alongside the hydration and barrier-sealing function of a regular face cream. Use after the ampoule step, before SPF in the morning, or as the final step at night.
The 100ml size also makes the Clean Arc Cream good value per use compared to standard 50ml face creams of similar positioning. If you are committed to running the Clean Arc ampoule daily, adding the cream in the same line means consistent actives across both the treatment and moisturizer steps.
Clean Arc Mist 100ml and Sunstick 22g
The Clean Arc Mist 100ml is a spray format for delivering the Arc formula as a midday refresh or after-cleanse prep step. Mists can be used over makeup for a hydration top-up, or on bare skin between routine steps. At 100ml it is a full-size bottle suited to regular spritz use throughout the day. The mist is a lighter-delivery complement to the ampoule and cream - it keeps the Arc formula on the skin continuously between main routine applications.
The Clean Arc Sunstick 22g is a stick-format SPF product for targeted or reapplication use. Sunstick formats are particularly practical for reapplying SPF over makeup mid-day, when a liquid sunscreen would disrupt foundation. At 22g it is a portable size for a bag or desk. The Sunstick carries the Clean Arc formula into the UV protection step, completing the sun-care layer of the routine with the same brand actives.
Clean Arc Ampoule Cushion Original Refill: coverage with Arc actives
The DMCK Clean Arc Ampoule Cushion Original Refill is a cushion compact that delivers the Clean Arc ampoule formula in a foundation-adjacent cosmetic format. Cushion compacts in Korean beauty are sponge-soaked compacts used with a puff applicator to apply a thin, blendable layer of skin-colored product that simultaneously hydrates and evens the skin tone. The Refill format means this is the cartridge for an existing Clean Arc cushion compact case. Check whether you need the full compact or just the refill cartridge before purchasing.
The Ampoule Cushion bridges the line between skincare and makeup - you get the coverage and skin-evening benefit of a cushion alongside the Clean Arc treatment formula. Use it as the final step in your morning routine after sunscreen, or in place of a separate sunscreen if the cushion carries an SPF rating.
Building a complete DMCK Clean Arc routine
A full DMCK Clean Arc morning routine: (1) Cleanse. (2) Apply Clean Arc Mist as a prep spray or hydration first step. (3) Apply Clean Arc Ampoule (10ml, 30ml, or DI 50ml) as the concentrated treatment step. (4) Apply Clean Arc Cream 100ml as the moisturizer. (5) Apply Clean Arc Sunstick or a separate SPF as the final UV protection step. Optional final step: Clean Arc Ampoule Cushion for coverage and tone. Evening: repeat steps 1-4, with the Arc Ampoule Forte on evenings when you want a more intensive treatment dose.
For a minimal Clean Arc entry point, the Ampoule 10ml and Cream 100ml are the two core products to test first. Once you know the formula works, expand to the full routine with Mist, Forte, and Sunstick.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
Which Clean Arc Ampoule size should I buy - 10ml, 30ml, or 50ml?
The 10ml is a trial or travel size - enough for 2-4 weeks to test the formula. The 30ml is the standard daily-use size for 2-3 months of morning and evening application. The Clean Arc DI Original Ampoule 50ml is the large supply format, lasting 3-4 months and offering better value per ml. If you are new to the line, start with 10ml to confirm the formula suits your skin. Once you are ready for ongoing use, the 30ml or 50ml is the practical choice based on how long you want the bottle to last.
What is the difference between the Arc Ampoule Forte and the standard Clean Arc Ampoule?
The Arc Ampoule Forte is a higher-concentration or strengthened version of the standard Clean Arc Ampoule formula. Forte means the actives are present at a higher level, delivering more intensive treatment per dose. The standard ampoule is appropriate for daily use and general skin maintenance. The Forte is for people who want a more intensive treatment effect, either on their first introduction or as an upgrade after consistent use of the standard formula. Introduce the Forte gradually if you have sensitive skin - starting with 2-3 times per week before daily use lets your skin adapt.
How do I use the Clean Arc Sunstick 22g for mid-day SPF reapplication?
Swipe the Clean Arc Sunstick lightly over the face in a cross-hatch pattern, then press gently with clean fingers or a sponge to blend. The stick format applies without disturbing existing makeup, which makes it practical for reapplication over foundation or cushion. Apply every 2-3 hours in direct sunlight, or after sweating heavily. The 22g size fits easily in a bag for all-day carry. Sunstick SPF is typically slightly lower than the original morning SPF50+ application, so consider using it alongside blotting papers on very oily skin to remove excess sebum before reapplying.
When should I use the Clean Arc Mist 100ml in my routine?
Use the Clean Arc Mist 100ml at multiple points: as a hydration layer between cleansing and ampoule, as a midday refresh over bare or made-up skin, or after outdoor activities to replenish moisture quickly. Spray from 20-25cm to create a fine mist and allow it to absorb without patting. As a between-steps product during your routine, the mist can boost hydration under the ampoule layer. As a standalone refresh, it maintains the Clean Arc actives on the skin surface throughout the day.
Is the Clean Arc Ampoule Cushion listing a refill or does it include a case?
The Clean Arc Ampoule Cushion Original Refill is specifically a refill cartridge - the cushion sponge without a compact case. You need to have the DMCK Clean Arc Ampoule Cushion compact to use the refill. If you do not already own the compact, check whether DMCK also lists the full compact set (case plus cushion) separately, or check the listing description for whether a case is included. Refills are more economical per use once you have the case, and they reduce packaging waste.
What skin types is the Clean Arc Cream 100ml suited to?
The Clean Arc Cream 100ml is a general face moisturizer in the Clean Arc system. The cream format is suited to normal, dry, and combination-dry skin. For oily or combination-oily skin that prefers lighter textures, the Clean Arc Mist or a gel-type moisturizer may be a more comfortable daily choice. The 100ml size is generous for a face cream; at daily morning and evening use it lasts approximately 3-5 months, making it practical to maintain a consistent routine without frequent reordering.
How many DMCK Clean Arc products does Skinsli carry?
Skinsli carries 11+ DMCK Clean Arc products including the Clean Arc Cream 100ml, Clean Arc Ampoule in 10ml and 30ml, Clean Arc Mist 100ml, Clean Arc Plus Ampoule 10ml, Clean Arc Ampoule Cushion Original Refill, Clean Arc DI Original Ampoule 50ml, Arc Ampoule Forte (two listings), and Clean Arc Sunstick 22g. All are authentic Korean DMCK products.
