What to Expect: Recovery and Results After Subdermal Laser Treatment

February 10, 2026 · Onyxa Medical™ — Clinical Education Team

One of the most common questions patients ask before any aesthetic procedure is: "How long until I recover, and when will I see results?" With subdermal laser treatment, the answer is encouraging — recovery is measured in days, not weeks, and results continue to improve for months after the procedure.

The First 24–72 Hours

The immediate post-treatment phase requires rest and gentle care. Patients can expect mild to moderate swelling, some redness, and possible bruising at the treatment sites. These are normal responses to the controlled thermal energy delivered beneath the skin. Cold compresses wrapped in cloth should be applied for 10–15 minutes at a time — do not apply ice directly. Patients should avoid alcohol for at least 72 hours, avoid hot baths, saunas, and steam rooms, and rest as needed. Gently cleanse with a mild, fragrance-free cleanser and apply arnica gel or CellDerma GF5 twice daily. Sleep with head elevated for facial and neck treatments.

The First 7–14 Days: Active Healing

During this phase, swelling and bruising begin to noticeably resolve. Patients should avoid direct sun exposure and wear broadspectrum SPF 50+ daily. No chemical peels, microdermabrasion, facial massages, or laser treatments during this period. Avoid retinoids, exfoliants (AHA/BHA), and strong active ingredients — use only gentle, hypoallergenic skincare products. Light walking is encouraged, but avoid heavy exercise until cleared by your practitioner. Light lymphatic drainage massage may be recommended. The skin may feel slightly firm or tight — this is a positive sign of the collagen contraction process already underway.

Weeks 2–4: Initial Results Emerge

As swelling fully resolves, patients begin to see the initial contour improvements. The initial improvements come from two mechanisms: collagen fiber contraction from the thermal energy, and (for treatments using the 980nm wavelength) reduction in fat volume through thermal lipolysis. At this stage, the skin appears smoother and tighter, though the full results are still developing beneath the surface.
