Many people may wonder how Profhilo, which primarily contains Hyaluronic Acid (HA), differs from regular fillers. Let’s take a look at the types of HA commonly used in the market, which can be divided into two main categories:
Cross-linked HA
This type of HA is chemically cross-linked using special ingredients like BDDE or PEG to create a gel-like consistency, making it resistant to breakdown in the body. Examples of cross-linked HA fillers include facial fillers like Restylane, Juvederm, or skin treatment fillers like Restylane Vital Light and Juvederm Skinvive. These fillers have a low degree of cross-linking, allowing them to spread well in the superficial layers of the skin. While they help restore volume and smooth wrinkles, they do not effectively stimulate long-term collagen production.Non-Crosslinked HA
Non-crosslinked HA does not have molecular bonds, allowing the body to break it down easily within 24-48 hours. An example of this type of HA is found in Juvelook, which provides temporary fullness to the face. However, it doesn’t stimulate collagen production long-term unless other substances, such as PDLLA found in Juvelook, are added to the formula.
Key Differences:
- Cross-linked HA fillers focus on providing volume and contour, lasting longer in the skin, but don’t stimulate collagen production significantly over time.
- Non-crosslinked HA offers temporary hydration and volume but is not designed for long-term rejuvenation or collagen stimulation.
