SINGAPORE — When 28-year-old Caitlin Lim noticed her under-eye circles darkening, she turned to an aesthetic clinic for help. Though initially hesitant due to her fear of needles, she took the plunge and got dermal fillers injected just above her cheekbones. The results? A fresher, more youthful look that made her feel more confident.

She’s not alone. In Singapore, a growing number of people in their 20s and 30s are turning to injectable cosmetic treatments such as Botox and collagen fillers. Once associated with older celebrities trying to freeze the ageing process, injectables are now becoming mainstream among younger adults looking to enhance their features or address skin concerns.

Dermatologists say that the number of young adults in Singapore undergoing such treatments has increased by 10 to 20 per cent since 2020, mirroring a global trend. According to the American Society of Plastic Surgeons, Botox usage among people aged 20 to 29 rose by 9 per cent between 2022 and 2023, while hyaluronic acid filler use increased by 8 per cent.

These treatments, which include dermal fillers and collagen boosters like Rejuran and Profhilo, work to improve facial volume, reduce the appearance of acne scars, and give the skin a smoother and more radiant look. However, they are not permanent — injections are typically repeated every three months to a year depending on the product and individual needs.

Costs vary, with Botox sessions starting from about $300 and fillers ranging between $600 to $1,000. While the investment is significant, many young patients believe it’s worth the cost.

Ms Lim, for instance, went on to try Botox in her jawline and forehead for a more contoured look, followed by Rejuran for overall skin rejuvenation. “The results were so good that I wanted to try more,” she said.

Subtle Tweaks Over Major Changes Today’s younger patients are not necessarily chasing dramatic transformations. Instead, they’re seeking subtle enhancements. Consultant dermatologist Dr Sean Leong from Livingstone Dermatology Clinic explained that Botox can help slim the jawline, subtly lift the mouth corners, or even soften a naturally stern expression.

Dr Joseph Toh, from Parkway MediCentre Dermatology Clinic, noted that Botox can also serve preventive purposes by slowing down the development of deep wrinkles through reduced muscle movement. Beyond aesthetics, it’s also used for medical issues like teeth grinding.

Meanwhile, collagen boosters such as Rejuran are gaining traction for their ability to lighten acne scars, brighten dark circles, and create a naturally lifted look, said Dr Evelyn Tay, founder of Lumine Dermatology & Laser Clinic.

Unlike surgery, injectables are temporary and less invasive. This flexibility appeals to many young adults who want to enhance their appearance without committing to permanent changes. "If you don't like the results, you can just wait for them to wear off," said 25-year-old Serene Lam, who regularly gets Botox in her jaw for a V-shaped face.

The Role of Social Media Social media has played a key role in the rising popularity of injectables. Platforms like Instagram and Lemon8 are filled with influencers sharing their experiences with aesthetic treatments, often showcasing glowing, poreless skin. This exposure has made younger audiences more open to exploring these options.

Fitness instructor Mandalyn Tan, 28, first tried Rejuran in 2023 to combat persistent acne and low self-esteem caused by her skin issues. Now, she gets maintenance boosters every three months. While she was initially hesitant about public perception, she began sharing her honest reviews online to help others. “I used to spend a lot on skincare that didn’t work. Now I feel it’s important to be transparent and share what really makes a difference.”

Safety, Moderation, and Long-Term Care While injectables are generally safe when performed by trained professionals, dermatologists emphasise the importance of moderation and informed decision-making.

Side effects such as bruising, swelling and mild bleeding are common. More serious complications, though rare, include the risk of infection or even vision loss if fillers are injected incorrectly. “It’s critical to ensure that treatments are done in reputable clinics by certified doctors,” said Dr Tay.

She also warned about “perception drift” — a psychological phenomenon where patients forget their original appearance and continually seek more procedures. “You might think you need more fillers, when in fact you don’t,” she said.

Too much Botox too early can also weaken facial muscles over time, said Dr Toh, adding that in some cases, the body may develop resistance to Botox, reducing its effectiveness.

There’s also the risk of an unnatural appearance. “If you go overboard with Botox, your face might look frozen or surprised all the time,” said Dr Leong. “Excess fillers can make your face appear puffy and artificial.”

Some patients also travel abroad to places like South Korea or Thailand for treatment, which can be risky if proper research isn’t done. “The last thing you want is someone unqualified injecting unknown substances into your face,” warned Dr Tay.

Ultimately, injectables should be seen as supplements to — not substitutes for — a solid skincare routine. “Sun protection, cleansing, active ingredients like vitamin C and retinol, and a healthy lifestyle still form the foundation for good skin,” said Dr Tay. “Without that, even the best treatments won’t make a lasting difference.”

As aesthetic enhancements become more accessible and accepted, young Singaporeans are increasingly opting to start early — but experts agree that education, moderation, and long-term care are key to achieving safe and satisfying results.
