Which of the following is a skin condition?

Acne is a skin condition, common in teenagers due to hormone levels changing

Sleeping on silk pillow cases and making sure my skin is moisturized, cleared my face right up. I am 35 years old and had acne and pimples all my adult life, until I made those changes recently. I wish somebody had told me about this earlier.

If you got this right and have Ance like this comment on curious how much I can get🤔😁

I have no acne💀

The clue is that they start with A!
