I'm a big supporter of sealing, but I don't see how aloe would be a sealer. The point of sealing is to form a barrier to "lock" moisture in, and "block" out excess environmental moisture. The only thing that can do that, is oils.

Some lighter ones would be grape seed, jojoba, or sweet almond oil. You can use tiny amounts and see if that helps.
