It's just that while acne can be disturbing we must also be careful when treating it.

But put ye on the Lord Jesus Christ, and make not provision for the flesh, to fulfil the lusts thereof.
(Rom 13:14 KJV)

Paul also says, warning about going to life where only body matters:

For he that soweth to his flesh shall of the flesh reap corruption; but he that soweth to the Spirit shall of the Spirit reap life everlasting.
(Gal 6:8 KJVA)

Now that doesnt mean we would lose our salvation..

But sow in spirit first... best to keep that in mind.

God bless.
