Not even motherhood has stopped the 28-year-old, better known as QiuQiu, from going under the knife again.
It was the side effects of motherhood that sparked her recent operation, carried out nearly nine months after she gave birth to her first child.
Last month, Ang, whose daughter Meredith was born in March, went to Korea for a fully sponsored facelift as well as a double eyelid procedure.
A year ago, in Seoul, she underwent major plastic surgery that included jawline reduction, zygoma (bony arch of the cheeks) reduction, chin augmentation and paranasal implants.
In 2013, she had a nose job and fat grafting to fill up her face.
In 2010, she went through a breast-filling treatment by a doctor for free. Two years later, she did alarplasty surgery in Thailand, to sharpen her nose.
All of the procedures were sponsored.
Speaking to The New Paper over the phone, Ang spoke about why she wanted to get more work done after becoming a new mum.
"I gained 35kg during my pregnancy. After I gave birth, I lost 25kg and the skin on my cheeks became very saggy and loose," she said.
"There were also fatty deposits under my chin that just won't go away."
Ang, who is 1.72m tall, was 83kg at her heaviest during her pregnancy. She is now 56kg and wants to lose another 4kg.
She added: "I've also wanted double eyelids for the longest time. It has always been on my checklist, so I thought I would do it this time round."
Ang has more than 283,000 followers on Instagram. She has received mixed comments from netizens after her most recent surgery.
Some remarked that she is "insecure" and has "low self-esteem", hence the multiple procedures within a short period of time.
Ang said: "I find it amusing that people think I have low self-esteem. I post photos of myself without makeup on my blog too, I don't really care.
"I do these surgeries because I am vain and I want to look even better."
She added: "I love myself so much and I have an expectation that I impose upon myself. I just want to look good and presentable, I am not doing it to look perfect."
Ang, who made a cameo in Jack Neo's first Ah Boys To Men movie in 2012 as recruit Ken Chow's (Joshua Tan) girlfriend, received many positive comments on her new look.
"There were people who said that I look like (Chinese actress) Angelababy and (Taiwanese actress) Vivian Hsu," she said with a laugh.
"I felt 'shiok' after hearing it. It's very flattering."
Ang said of her plastic surgery procedures: "I was quite nervous the first and second time, as they were big surgeries and I was new to it."
But for her third plastic surgery procedure in three years, she said: "I was not nervous at all this time round. I am like a seasoned player already... It simply felt like a visit to the dentist."
Ang does not think she is addicted to plastic surgery, but sees it as a way to improve upon her looks.
"Before my eyelid surgery, I would say I am 70 or 80 upon 100," she said,
"Now, I totally look Eurasian, I feel like I am a 90 out of 100."
She was also quick to emphasise that the recent surgery did not take time away from her baby as she was in the hospital for only one night.
She was in Korea with her daughter, her domestic helper and her husband, Mr Joshua Tan, 43, a photographer.
She said: "I was all bandaged up, but I was still carrying her and she still recognised my face and wanted to play with me.
"It was only that one night that I wasn't with her and she was really upset."
Ang wants to encourage new mums not to ignore their appearance.
"Once you give up, you will become a 'huang lian po' (Mandarin for frump). Sometimes... I see aunties who are not old, but look like they have given up," she said.
"Continue to doll up, dress up, diet and exercise. Even when I was super fat, I told myself that I can lose the weight and that I cannot let myself go after giving birth."
Ang thinks she will have just one child for now, as she does not want to go back to being fat again.
As for her plastic surgery journey, she felt she is pretty much done - for now.
"If I do anything to my face again, it's most probably to 'touch up', things like fillers or botox," she said.
"However, I won't do anything major again. No more sewing, no more cutting, no more knives - just needles will do."
I find it amusing that people think I have low self-esteem. I post photos of myself without makeup on my blog too, I don't really care. I do these surgeries because I am vain, and I want to look even better.
WHAT DOES THE DOCTOR SAY?
According to consultant psychiatrist Dr Ang Yong Guan, it is not psychologically healthy for a new mother to want to have plastic surgery shortly after giving birth - whether minor or major - especially for aesthetic reasons rather than medical ones.
He told TNP it is not advisable for three reasons:
1) There are post-natal hormonal changes in the body and it requires time, usually at least a year, to naturally adjust and return to the pre-natal state.
Plastic surgery tampers with this natural process.
For instance, it is biologically acceptable to put on weight and "be out of shape" .
This is only temporary. With the passage of time, exercise and proper nutrition, the body will get back in shape and the temporary "obesity" will go away.
2) Because of the hormonal changes, at least one in two new mothers have been shown to have post-natal blues characterised by irritability, short temper, anxiety, negative thoughts and low mood not amounting to clinical post-natal depression, which affects one in 10 post-natal mothers.
Given this high percentage of post-natal blues, the risk of making hasty decisions - especially when they have negative thoughts such as they are no longer slim and pretty or their husbands no longer find them attractive - is there.
3) New mothers have a new role of bonding with their babies. They should focus on this role.
