Buying Skins via BLTC
The gemstore armor skins are one-use aesthetic items. That is, they can be used one time each on a particular piece of armor (of the correct “weight”: light, medium, heavy, depending on the skin in question).
They do not change your stats, they just update the look of the armor piece.
If you want to use it on armor prior to your intended “keeper” set, you can carry over the new skin through use of transmutation stones. Bear in mind that once your armor is at L80, you must use Transmutation Crystals, which must be acquired from the gemstore, or if you’re lucky, you can get them as a bonus to your Daily completion award or from Black Lion chests.
