Secret RF microneedling radiofrequency in Los Angeles supervised by Dr. K. Charles Kim. Texture, scars, and laxity for all skin types.
Book ConsultationSecret RF microneedling in Los Angeles by Dr. K. Charles Kim combines traditional microneedling with fractional radiofrequency energy delivered through insulated needles directly into the dermis — producing collagen stimulation and skin tightening simultaneously. The treatment effectively addresses acne scarring, fine lines, stretch marks, and mild skin laxity. Dr. Kim offers Secret RF as part of a comprehensive non-surgical skin protocol with significantly less downtime than ablative laser.
Insulated microneedles deliver radiofrequency energy at controlled depths (0.5 to 3.5 mm), bypassing the epidermis to heat the dermis where collagen and elastin reside. Because the epidermis is largely spared, treatment is safe across all skin types — including darker complexions where laser carries pigmentation risk. Settings are customized per zone and concern. A series of 3 sessions spaced 4–6 weeks apart is typical for optimal results.
Days 1–3: Redness, mild swelling, and pinpoint marks; gentle cleansing and sun avoidance recommended.
Days 4–7: Skin returns to normal appearance with subtle textural improvement.
Months 1–6: Progressive dermal remodeling produces visible tightening and scar improvement; maintenance every 6–12 months sustains results.
Under-eye bags and puffiness refer to the protrusion or swelling of fat pads beneath the lower eyelid, often paired with dark shadows and crepey skin.
The condition is largely hereditary but can be accelerated by aging, fluid retention, and loss of midface volume. Both younger and older patients are affected.
Dr. Kim personally performs lower blepharoplasty using a transconjunctival approach when possible to reposition or remove fat without external scarring. For patients with mild puffiness only, non-surgical options may be appropriate.

Acne scars include ice pick, boxcar, and rolling scars left behind by inflammatory acne. They create uneven texture and can persist long after active breakouts resolve.
Scarring occurs when severe acne damages the deeper dermis. Genetics, severity of acne, and time to treatment all influence final scar appearance.
Dr. Kim's practice offers CO2 laser resurfacing, microneedling with radiofrequency (Secret RF), and pigment-targeted lasers (Picoway) to smooth texture and improve skin quality. Treatment plans are layered for best results.

Loose facial skin presents as mild to moderate laxity along the cheeks, jawline, and neck. It is too early or too mild for surgical facelift but no longer responds to skincare alone.
Skin laxity develops with collagen and elastin loss over time. Patients in their 30s through 50s often seek non-surgical tightening before considering surgery.
Dr. Kim's practice offers Ultherapy, Thermage FLX, Sofwave, and Oligio X, each targeting different tissue depths with ultrasound or radiofrequency to stimulate collagen remodeling.

Secret RF can treat the face, neck, and body areas prone to laxity, acne scarring, stretch marks, or uneven texture. Common zones include the cheeks, jawline, neck, and abdomen. During your visit, Dr. Kim's practice identifies the areas best suited to RF microneedling for your skin goals.
Most patients achieve optimal results with a series of about 3 Secret RF sessions spaced roughly 4 to 6 weeks apart, though the exact number depends on skin condition and goals. Improvement continues for several months as collagen rebuilds. Dr. Kim's team customizes your treatment plan to the concerns you most want to address.
Secret RF combines microneedling with radiofrequency energy: tiny needles create controlled micro-channels while RF heat is delivered into the dermis, triggering the body's natural collagen-remodeling response. This dual action tightens skin and refines texture from within. The result is gradual, natural-looking firmness and smoother skin over a series of treatments.
Secret RF is a fractional radiofrequency microneedling treatment that delivers RF energy into the deeper layers of the skin to stimulate collagen and tighten tissue. It improves fine lines, acne scars, enlarged pores, and overall skin texture with minimal surface disruption. Dr. Kim's practice offers Secret RF as part of a tailored approach to skin rejuvenation in Los Angeles.
