I was asked this question recently & it struck me that some people really have no idea what microdermabrasion is, nor do they know what is good (or bad) for their skin.
I wish people would do some of their own research so
1) they don't get conned (don't just believe people you think are professionals e.g. beauticians. Even doctors - if something doesn't sound quite right, GET A 2nd OPINION!)
2) they don't have unreasonable expectations of what they are paying for.
"Facial" can mean lots of things & can include the following:
1) "deep cleansing" - beautician cleaning your face & massaging it at the same time sending you to sleep
2) steaming your face to "open your pores" - which is a myth.
3) then they press & squeeze like mad to extract out blackheads which will leave the face red & inflamed for a couple of days..after which you may have a bad acne breakout from all that irritation. They tell you they have cleaned out all the "dirty things" & "poisonous blood". Fact is, the "dirt" is just oxidized sebum (=your own natural oils which have reacted with oxygen in the air). The "poisonous blood" is because you're bleeding from all that trauma to your face.
4) Then they may charge you an arm & a leg for massaging an "ampoule" (an ampoule of don't know what) into your face - that's an extra RM50 - RM100. You can pay that kind of money to buy a good serum & massage it into your face for a whole month.
5) Maybe topped off with a mask & leave to you to sleep for half an hour to give "value for money" because you paid RM380 for 2 hours of treatment.
To be fair, there are many well-trained competent beauticians out there who don't do the horrible things described above. Unfortunately, there are too many of such people who call themselves beauticians (after a 3 day training course)tarnishing the industry with such service. Let's not get started with the ones who inject all sorts of rubbish from industrial silicone to animal extracts.....
Does one "need" a facial? - Answer your own question.
A microdermabrasion removes dead skin & removes sebum from blackheads & whiteheads in a non-traumatic manner leaving the skin feeling smooth, clean & clear. You can walk out straightaway looking good, not with red marks on the whole face.
I think that answers the question!
