Is ultherapy and fractional co2 a good combination for treating skin sagging and tired look? If not, what would it be?

Yes.The combination of Ultherapy and fractioanl CO2 laser is a safe and very effective treatment for improving and tightening the skin.  It is especially effective in the neck and decolletage areas.  The combination can be performed during the same visit or separately, with the Ultherapy treatment being the first one to be performed in most cases.The combination on the face is the best non-surgical treatment option for maximizing skin tightening and lifting, while simulataneously improving skin discolorations and wrinkles.  Adding the fractional CO2 laser does produce some downtime (4-5 days), noting that there is no downtime when Ulthera is the lone treatment.The link below provides more information.I hope this helps.

While Ultherapy and Ablative fractional resurfacing complement each other well, if you are noticing all of these changes in a short period of time at a young age it may be worth undergoing a thorough medical evaluation to make certain you do not have any underlying health issues.

Every patient is different, and patient's faces change from year to year.  An evaluation of each person's particular concerns must be done in person to determine which is the best treatment or treatments for them. In general, ultherapy can help tighten and lift sagging skin of the face and neck.  Fraxel Repair, which is the carbon dioxide laser (CO2), can help tighten more than the Fraxel Restore / Dual laser but the CO2 laser, even the fractional type, causes purposeful wounding in the skin that needs almost two weeks to heal so there is down time and the risk of scarring is greater on the neck skin than that of the face, so it can't be used aggressively in that location to get a lot of neck lifting.ThermiTight, which is an internal ThermiRf treatment, can help tighten the neck along with Fraxel Restore, or Fraxel Dual for improved skin texture.

This combination is amazing for tightening, texture, tone and anti-aging.  The question is do you need this for your goals?  you would need an inperson consultation.  Sometimes there are less invasive options such as fractional non ablative lasers, skin care, fillers ect.  I suggest going to see a cosmetic dermatologist with expertise in lasers, fillers, and anti-aging skin care.  Best, Dr. Emer.

Ultherapy and fractional CO2 treatments can be used in combination and can help more together than alone.  Ultherapy helps to lift and tighten the tissue under the skin, while fractional CO2 treatment has more effect on the skin itself.  You would need to be examined to determine if you might be a good candidate for either treatment, but I would say it would be unusual for a 24 year old to need Ultherapy or fractional CO2 treatment.  

Ultherapy would be a good choice to get tightening of your skin in the mid and lower face and jowls.Fractional lasers can improve the texture of your skin.I recommend that you start using a retinoid based cream like RR Retinoid Repair by KareSkinRead the Ultherapy book provided on the link below.
