It really depends on your individual needs and goals. Filler is a great way to add volume and contour to the face, while Profhilo is a great option for skin rejuvenation. Filler can be used to fill in wrinkles, create fuller lips, and reduce hollows under the eyes. It works by adding a gel-like substance into areas of the face that need more volume or definition. The results are noticeable immediately, but they can last anywhere from six months to two years. Profhilo is an injectable hyaluronic acid treatment which helps to improve skin tone and texture by stimulating collagen production and hydration. It's also known as 'bio-remodelling' as it helps to reshape the face over time. Results may take up to four weeks to become visible but can last up to six months with just two treatments required per year.
