New beauty trend taking TikTok by storm helps people remove every hair on their face - but is it helpful or harmful?

There's a new beauty craze making the rounds on TikTok - and it involves taking a bizarre measure in order to remove every single hair from the face.

Makeup fanatics are buying up a new product called hair identifier spray, which creates a dramatic layer of what looks like white spray paint all over the face, in order to show every single hair.

The spray, which being sold by multiple brands online, is supposed to make dermaplaning, or shaving your face with a small, hand-held instrument, much easier.

While it's unclear exactly what the spray is made of - one popular brand promises that theirs is 'infused with botanical extracts' and antioxidants - the point is to highlight all of the hairs. 

In one video, which has now reached more than 25 million views, beauty influencer Rachel Madison Carlisle tried out the product for the first time, and said it made her notice neck hairs she didn't know existed before.

Another US-based TikTok user, who goes by Janet J, also gave the spray a spin, and said that she didn't know she had that much hair in the first place.

But is hair identifying spray really good for your skin, or does it have the potential to break you out, or even cause an infection? 

FEMAIL spoke to dermatologists to find out whether or not it's something that could be harmful to your skin.

Ohio-based dermatologist Dr. Mona Mislankar told DailyMail.com that many hair identifying sprays on the market right now contained heavy fragrances and were created with alcohol - which can cause different reactions for different skin types.

'If one does not have particularly sensitive or acne prone skin - this might be an okay option and a good option to identify hair,' Dr. Mislankar explained. 

However, it's important to note that one of the most popular sprays on TikTok, SKNBODY, is non-comedogenic and free of sulfates, parabens, phthalates and formaldehyde.

According to New York City-based dermatologist Dr. Jody A. Levine at Plastic Surgery & Dermatology of New York City, any product applied to the skin can have risks.

Dr. Levine explained these kinds of sprays could contain ingredients that clogged the pores, and recommended looking for sprays that were non-comedogenic, and free of sulfates and parabens instead. 

The spray itself also won't cause infections, but it's important to make sure that your skin is clean before and after you remove the hairs, as that will minimize bacteria on the skin and potential infection risks from dermaplaning.

But the actual product is not all bad news.  

Dr. Levine told DailyMail.com that hair identifying spray did make it easier to see the fine hairs on the face, and could help provide a smoother shave since it prevented friction and protected skin from any cuts.

However, the spray isn't on your face for very long, she noted, which means that some of the benefits the product promises may not have a long-term effect.  

'While some sprays are formulated with antioxidant ingredients that aim to protect your skin from free-radical damage, the spray is not on your skin for very long and the antioxidant benefits are not as significant,' Dr. Levine said.

In a statement to the DailyMail.com, a representative at SKNBODY said that they take product safety and efficacy quite seriously.   

'Our Hair Identifier Spray is formulated with the utmost care to ensure it is suitable for all skin types, including sensitive skin,' they stated. 'The fragrance used in our product is tested to minimize any risk of irritation or breakouts.'

The brand also encouraged users who have sensitive skin to perform a patch test before applying the product fully.  

'We continuously work with experts in the field to ensure our products meet the highest standards.'

But in general, Dr. Mislankar told DailyMail.com that many of her patients loved dermaplaning. 

'It allows one to have a smooth canvas while applying their skincare and makeup and can absolutely elevate an entire look,' Dr. Mislankar explained.

But she warned dermaplaning can cause acne for those who have sensitive or acne-prone skin. 

'Sometimes this is due to the physical act of the procedure itself or sometimes due to the products used before,' the dermatologist said.
