About No.1 Easy Peasy Cleansing Oil

Overview

No.1 Easy Peasy Cleansing Oil is a rich oil cleanser from Numbuzin, a brand based in Korean. The formula is built mainly around hydration. The ingredient list runs to 13 ingredients, each broken down in full below.

Texture and finish

By its ingredient list the formula reads as rich: occlusives and butters sit high enough in the order to give it real weight on skin. The oils in it point to a dewy, emollient finish rather than a matte one. Hydration is handled by Isopropyl Myristate, Ethylhexyl Palmitate and Caprylic/capric Triglyceride, humectants that pull water into the upper layers of skin rather than sealing it there.

What the formula does

Hydration: High. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Isopropyl Myristate, Ethylhexyl Palmitate, Caprylic/capric Triglyceride and Diisostearyl Malate.

Who it suits

On richness alone it suits Dry and Combination (dry) skin best, and is the least natural fit for Combination (oily) and Oily skin. Nothing in the list is flagged as a common irritant, which is a reasonable starting point for reactive skin — though a patch test is still the only way to know.

What it does not target

The formula contributes little or nothing on barrier support, antioxidant protection, oil control and brightening and tone. That is not a fault — most products are not meant to do everything — but if one of those is your priority, this is not the product that will address it.

What is not in it

Reading the full list, the formula is essential-oil-free, no drying alcohol, paraben-free, silicone-free, microplastic-free and sulfate-free. Those claims come from the ingredient list itself, not from the packaging. It does contain fragrance, worth knowing if your skin reacts to any of them.

Where it fits in a routine

It can be used morning and evening. In a routine it goes first step. Use on damp skin and rinse thoroughly. Follow with a toner or essence while skin is still slightly damp.

This summary is generated from the product's ingredient list. It is not a review, it is not the brand's own marketing claims, and it does not replace advice from a dermatologist.

Fungal acne (malassezia)
6 ingredients could feed malassezia: Isopropyl Myristate, Sorbeth-30 Tetraoleate, Ethylhexyl Palmitate, Sorbitan Sesquioleate, Macadamia Ternifolia Seed Oil, Helianthus Annuus Seed Oil. That is about the yeast's food supply, not a prediction that you will break out.
