The types of poly-L-lactic acid dermal facial fillers used to treat wrinkles on the face are one of the most frequently asked questions. Known as New-fill, poly-L-lactic acid uses microbeads made from synthetic polymers as a dermal filler. Poly-L-Lactic Acid Dermal Facial Filler works slightly differently from other types of dermal fillers; the microbeads irritate the skin, increasing fibroblast activity (cells responsible for collagen synthesis), resulting in increased skin thickness and collagen levels in the skin. In other words, it helps the skin increase its own collagen levels. Poly-L-Lactic Acid Dermal Facial Filler does not act alone but rather serves as a stimulant.

Its biggest advantage is that its effects last for a very long time. A single treatment can be effective for up to two years. This is an attractive option for people who do not have the time to undergo continuous treatment.


The polymer in Poly-L-Lactic Acid Dermal Facial Filler has been used in medicine for many years, proving its safety. Additionally, since this polymer is synthetic, the risk of your skin reacting adversely is low, and there is no need for an allergy test before treatment. However, some people may be allergic to lidocaine, which is used in the filler solution. If you know you have such an allergy, you should inform your doctor.

Since fillers stimulate collagen production in the skin, they can be considered a product that truly reverses ageing. However, as with all fillers, the results are not permanent. Although it takes time, the microbeads break down and are absorbed by the body.

What is post-treatment skin care like?

Immediately after treatment, your face may appear red, bruised or swollen. These effects usually disappear completely within a week. In about 10% of patients, side effects may occur in the form of swelling under the skin, which can take 1-2 months to disappear. However, these side effects usually disappear within a week.

After Poli-L-Lactic Acid Dermal Facial Filler treatment, the most important thing to keep in mind is to massage your face regularly as instructed. This is necessary to distribute the injection evenly and balanced across your face. Failure to do so may result in minor swelling in some areas of the skin.

Although your face will begin to improve after one week, you will only see the full results of the Poly-L-Lactic Acid Dermal Facial Filler two to three months after treatment.
