If it’s just been 4 days since your treatment, then you should give it some more time to settle. Use ice packs for Swelling, drink plenty of water to keep yourself hydrated. In few days swelling will settle and then you should see the results. Or if still concerned contact your injector. Thanks Dr Prerna Mittal InspireMe Clinic
Fillers cannot take the nasolabial folds away completely. Nasolabial are normal part of an anatomy of face. They get more pronounced with sun damage to the skin, ageing due to breakdown of collagen or reduction of facial fat pad. With dermal fillers in the cheeks improves the appearance of nasolabial folds sometimes little filler at the nasolabial fold is also need along with cheeks. An experienced injector would know where to implant for better results. Thanks Dr Prerna Mittal InspireMe Clinic London
There are so many Laser treatments available in the market, all claim to be good. But at younger age like in 20's or late 20's good skin care regime is most important to prevent early breakdown of collagen. High SPF sunscreen, exfoliators, moisturisers and most important balance diet, plenty of fluids and exercise. As very wisely said by fellow clinician risk:reward ratio cannot be justified with Lasers. I usually treat my patients with Profhilo, it is a pure hyaluronic acid without any additives, injected under the skin, helps to moisturise the skin by drawing more water molecules under the skin gives healthy plump and glow to the skin also helps with bioremodelling of skin stimulate skin's own collagen to produce more. No lasers are required.
Life style contributes a lot in early development of wrinkles. You could try tear trough treatment with fillers but I would suggest if you got a busy lifestyle then eating healthy diet, plenty of water and 8 hours of sleep along with high spf sunscreen would help you more.
Always contact your injector if you concern about your treatment. If lump is not hard, red or tender then it should settle with massage with arnica cream. But you should contact your injector if you are concerned of a lump.
