Thank you for your question. The point is really what you would like to achieve with the skin booster injections before a deep plane facelift. If this is about promoting healing, it may be more valuable to have a couple of sessions of hyperbaric oxygen therapy before your treatment and three or four sessions after your treatment. Hyperbaric oxygen therapy has a fairly direct impact on the defences against infection and promotes the restoration of collagen in the wound areas. Additionally, good nutrition and general vitamin supplements are also important parts of preparation for the surgery. If you are referring to the improvement of skin texture using skin boosters prior to the deep plane facelift, it probably does not matter whether you do it before or after your treatment. However, this is best discussed with an aesthetic medicine specialist who can provide specific recommendations based on your individual needs and goals.
