Private collagen filling is a medical aesthetic anti-aging treatment targeting aging issues in women's intimate areas. By injecting medical-grade collagen, it addresses problems such as laxity and dryness in intimate regions. The following provides a detailed introduction covering core principles, target demographics, advantages, and precautions:

Core Principles

Physical Filling + Structural Support: The vaginal wall and pelvic floor muscles in the intimate area consist of approximately 70% collagen. Injected medical-grade collagen acts like a "scaffold," rapidly filling gaps caused by collagen loss due to aging or childbirth, immediately supporting lax vaginal walls and mucosal tissues to restore firmness. For instance, Lanmi Private Type III Collagen's 164.88° triple-helix structure forms a mesh-like scaffold, increasing the density of vaginal wall folds.
Stimulation of Regeneration + Long-term Repair: The injected collagen activates local fibroblasts, prompting them to secrete their own collagen and initiating self-repair of intimate tissues. Over time, newly formed collagen gradually replaces the injected collagen, thickening the mucosal layer from the root, enhancing hydration, and delivering long-term anti-aging effects.
Optimization of Microenvironment + Health Protection: Collagen possesses strong water-locking capabilities, relieving dryness and itching of intimate mucosa. It also strengthens local immune barriers, inhibits the growth of harmful bacteria, reduces the risk of inflammatory infections, and promotes local blood circulation, improving issues such as pigmentation of the labia minora and majora.

Target Demographics: This treatment is suitable for a wide range of individuals, including postpartum mothers experiencing laxity and urinary incontinence due to vaginal expansion and collagen fiber rupture; women in menopause suffering from atrophy, dryness, and itching due to declining estrogen levels; and women seeking intimate health and aesthetics, wishing to improve their quality of life, including those with thin intimate mucosa, pain during intercourse, or dryness.
Project Advantages

High Safety: Mainstream products like Lanmi Private Type III Collagen utilize recombinant human collagen, with components identical to the body's own Type III collagen, ensuring excellent compatibility and virtually no rejection reactions. Most are classified as Class III medical devices, approved by the National Medical Products Administration, with production and operation processes under strict supervision.
Minimally Invasive and Convenient: The treatment requires no surgery, involving only fine-needle injection. A single session typically lasts 15–30 minutes, with only mild redness and swelling post-procedure, which generally subsides within 24 hours, allowing patients to resume normal daily life and work immediately.
Natural and Comprehensive Results: Unlike traditional fillers that may cause stiffness, this approach achieves improvement by stimulating the body's own collagen regeneration, resulting in natural enhancements in firmness and hydration. It addresses functional issues, improves appearance-related pigmentation, and alleviates mild urinary incontinence.

Precautions

Pre-treatment Contraindications: Individuals with allergies must inform their doctor in advance; those allergic to collagen should not undergo the procedure. If the intimate area is in an acute inflammatory phase, inflammation must be resolved before filling. Pregnant or breastfeeding women should carefully select this treatment under medical guidance.
Post-treatment Care: Avoid sexual intercourse and sitz baths for two weeks post-treatment; refrain from vigorous exercise and bathing for the first three days. Maintain cleanliness of the intimate area and use medical repair products as prescribed. Avoid high-temperature environments such as saunas, quit smoking, limit alcohol consumption, and maintain a regular sleep schedule to minimize rapid collagen loss.
Treatment Course and Results: The effects of a single filling session typically last 6–12 months. Mild issues may show improvement after 1–2 sessions, while moderate issues usually require three sessions to establish a "collagen regeneration cycle" for sustained results. Severe laxity or damage may necessitate five or more sessions, and results can be further enhanced by combining with pelvic floor muscle training.
