I ADORE this mask. Yes it is HOT! Once you use it a couple of times, your skin will get used to it and it won't get as red. If you aren't used to tingle masks, this may not be the best one to use at first, as it is potent. I have active acne, scarring and cystic acne, this mask helps reduce all types. I love using this the day before a big event to help even out my skin tone. But DO NOT use this the first time before an event, as your skin may be red for a while after on the first couple of uses.
