You did the hard part. The weight came off. Then you caught your reflection and the skin was still there, softer at the stomach, the arms, the neck, the face. It can feel like you won the number and lost the mirror.

The fat was part of the shape. When it leaves faster than collagen can catch up, the scale says success and the skin says otherwise.

That is the appointment we built. It is not one visit.

What we do at The Hidden Trough

The Hidden Trough Aesthetics in Aiken treats the skin left behind, not just the number on the scale. The first pass is cryo stacked with ultrasound.

Cooling is in the sequence for a reason. After cryolipolysis, researchers measured a remodeling signal in treated skin: higher type I procollagen, higher TGF-β, and more of the collagen chaperone HSP47 than in untreated skin (Stevens et al., Aesthetic Surgery Journal, 2022). Cryo is the contour and calm-down step. It is also the start of the tightening signal.

Ultrasound is the delivery step. Low-frequency ultrasound, the kind studied as sonophoresis, opens the outer skin barrier so a topical can travel farther than it would from a rub-in alone. On that pass we use it to push our proprietary serum deeper. Same visit. Same light. No second appointment just to get product on the skin.

One cryo session will not finish the job. Collagen remodels over weeks, and loose skin after a big loss needs repeat passes. How many is not a package we pick in advance. It may be 3. It may be 7. The skin makes that determination.

When the skin needs more than a serum

Mild laxity can respond to cryo and serum. Looser skin, crepey texture, stretch marks, or a face that looks emptied out after the weight drop usually needs a collagen step. That is Scarlet RF microneedling.

Scarlet RF is bipolar radiofrequency delivered through microneedles. The published record for this device class is about collagen and elastin, not a surface cream. Fractional bipolar RF has been shown to set off neocollagenesis and neoelastogenesis, with new dermal tissue replacing the treated zones over about 10 weeks (Hantash et al., Lasers in Surgery and Medicine, 2009). A 2026 review of 41 radiofrequency-microneedling studies, 15 of them randomized, found consistent gains in laxity, texture, and dermal density. The channels from the needles also give the serum a way in.

Most offices still run one device and two or three steps. Our enhanced protocol takes it further by integrating a potent exosome serum to accelerate healing, advanced skin prep for optimal results, ultrasound-guided precision for targeted treatment, soothing cryotherapy to calm redness, and a relaxing red light therapy session to boost recovery.

That is the 5-device, 10-step Scarlet visit: prep, Scarlet RF, exosome serum, ultrasound, cryotherapy, and red light, sequenced in one appointment instead of spread across a calendar. Cryo and ultrasound are not add-ons you book later. They are in the protocol.
