AHA ingredients that help remove sebum and dead skin cells that could not be discharged are acidic and can cause considerable irritation to the skin.
backed by evidenceSince Dermalans Gel was used to temporarily provide stimulation, when removing it, please reduce stimulation as much as possible.
backed by evidenceSebum prevents moisture evaporation and acts as a natural protective barrier that protects the skin from external stimuli.
plausible, not testedIt is essential to the skin, but if it is secreted excessively or stagnates in pores without being naturally discharged, it causes trouble.
plausible, not testedPetathione acid, created when aged cells and sulfur meet, is a natural sterilizer with powerful anti-inflammatory·sterilizing effects. In this process, dead skin cells accumulated in pores are gently removed, helping trouble-prone skin.
plausible, not testedFirst, to soothe trouble, reducing physical stimulation is most important.
plausible, not tested3 types of ceramide strengthen skin density and the skin barrier at the same time in a form similar to the skin barrier.
partly backedThe stratum corneum, in which the moisture layer and lipid layer form layers, is composed of ceramides, cholesterol, and fatty acids. When the skin barrier is damaged due to physical stimulation, the external environment, aging, etc., 3 types of ceramide similar to my skin make the skin barrier firmer.

partly backedConstitution improvement to skin that does not develop trouble, Dermalans Gel
overstatedIf sebum and dead skin cells repeatedly accumulate in pores without being discharged, the constitution changes to one that easily develops trouble. You are always carrying in your pores the seeds of trouble that can rise at any time.
overstatedSoothing visible trouble is also important, but removing the cause of trouble and changing the skin constitution is most important.
overstatedDermalans Gel contains sulfur and Portulaca oleracea extract that help soothe the skin, and sodium hyaluronate that replenishes moisture, etc., minimizing skin irritation and helping the skin build strength on its own so it can change to a constitution that does not develop trouble.
overstatedAHA has a small molecular weight and high skin penetration, so it removes unnecessary dead skin cells and sebum inside the skin. It supplies moisture to the skin, improves pigmentation, and helps the skin become elastic.
overstatedPortulaca oleracea extract, which has excellent soothing and antibacterial effects, helps with various skin conditions such as trouble-prone skin and eczema, and builds the skin's resistance against external stimuli and bacteria, soothing sensitive skin.
overstatedFor skin concerned about frequent trouble, it naturally discharges sebum and dead skin cells accumulated in pores, creating an environment in which trouble does not recur.
overstatedDermalans Gel is a difficult product to use, but if you know it properly and use it, you will definitely be able to see with your eyes the skin becoming healthy.
overstatedFor skin concerned about trouble over a wide area, if you adjust the formulation and usage amount, it can be applied to all areas where trouble is a concern, such as the face, chest, and back.
no supporting source foundWas trouble quickly soothed? 92%
no supporting source foundIf you use Dermalans Gel, pores clogged with sebum and dead skin cells open, and it may temporarily look like the amount of sebum has increased. It is a very natural phenomenon, so don't be alarmed. As the dead skin cells and sebum accumulated in pores are discharged, skin tone will become uniform.
