About Power Proof Pen Liner
Overview
Power Proof Pen Liner is a watery-light skincare product from BLACK ROUGE. The formula is built mainly around hydration. The ingredient list runs to 17 ingredients, each broken down in full below.
Texture and finish
By its ingredient list the formula reads as very light — essentially a water-and-humectant base with little emollient weight. With almost no emollient load it should absorb quickly and finish close to matte. Hydration is handled by Butylene Glycol, Ethylhexylglycerin and Water, 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 Butylene Glycol, Ethylhexylglycerin, Water and Alcohol.
Who it suits
On richness alone it suits Combination (oily) and Oily skin best, and is the least natural fit for Dry and Combination (dry) skin. A few ingredients carry irritation flags, so reactive skin should patch test before using it on the whole face.
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 fragrance-free, essential-oil-free, paraben-free, silicone-free, microplastic-free and sulfate-free. Those claims come from the ingredient list itself, not from the packaging. It does contain drying alcohol, 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 before moisturiser. Tap along the orbital bone with your ring finger; product migrates upward on its own.
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.
