[Doctor's Column][Lifting ④] 'Density' 300 Shots vs. 600 Shots, Criteria for Choosing the Optimal Solution for My Skin

Hello, this is Director Kim Tae-hee of Sunae Maypure. Many patients who visit our clinic after deciding on the premium radiofrequency lifting procedure, 'Density,' ask a common question in the consultation room: "Which should I choose, 300 shots or 600 shots?" As this is a high-priced procedure, it is natural to be cautious in order to obtain the optimal results relative to the cost. Today, going beyond simple price comparisons, I will clearly present the criteria for the 'truly optimal number of shots' tailored to your skin condition, based on medical evidence and thermodynamic principles. 1. The Essence of a Shot: 'Accumulated Energy,' Not Just a Simple Count. The number of shots in Density is not simply the number of times the machine is applied to the skin. It is the amount of "total accumulated thermal energy (Joules)" delivered to the dermis layer to regenerate collagen. For aged collagen to contract and new collagen to be synthesized in large quantities (Neocollagenesis), the dermis layer must reach a specific temperature (40–60°C) and maintain it for a certain period of time. This is the same principle as the need for sufficient heat to be sustained when boiling water. In other words, the key to a successful procedure is to seamlessly accumulate energy across the broad face to surpass the 'critical point of collagen regeneration.' 2. 300 Shots vs. 600 Shots Comparison Chart at a Glance. The recommended number of shots varies depending on the client's areas of concern and the degree of aging. Category 💎 Density 300 Shots (Personalized Intensive Repair) 💎 Density 600 Shots (Full Facial Bone Structure Reconstruction) Recommended for: - Early aging in 30s - Concerns in specific areas (deep cheek fat, jawline, etc.) - 40s and older - Loss of overall facial elasticity and sagging contours Purpose of Treatment: - Prevention of early aging - Intensive tightening of small areas - Powerful tightening and remodeling of the entire mid/lower face Medical Principles: - Improves density by concentrating energy on small problem areas - Maximizes synergy with dual mode (monopolar + bipolar) from forehead to jawline Precautions: - High probability of failure to reach the collagen regeneration threshold when distributed across the entire face - Beneficial for long-term (over 1 year) collagen maintenance across all skin layers 3. The Necessity of '600 Shots' Proven by Global Clinical Papers Data from the latest dermatological papers also proves that a sufficient number of shots (accumulation of energy) is essential for meaningful changes across the entire face. ✅ Hundreds of shots are required even for the narrow eye area: According to a study published in 2026 (PMID: 41710528), a total of 300 to 600 shots were intensively used for both eyes alone to improve wrinkles in the narrow and thin periorbital area. This is evidence that the delivery of more than 600 shots of energy is essential to transform the dermal layer of the entire face. [Reference] Sequential Monopolar-Bipolar Pulsed Radiofrequency for Non-Invasive Periorbital Rejuvenation: A Case Series. ✅ The law of proportionality between treatment time and number of shots: In another study published in 2026 (PMID: 41664412), the treatment time that produced significant elasticity improvement results satisfying 100% of patients was '30 to 60 minutes'. When converted to Dencerty shots, this corresponds to approximately 600 to 1,200 shots. [Reference] Real-World Evaluation of Sequential Monopolar-Bipolar RF Device for Rejuvenation 💡 Director's Comment: If 300 shots (approximately 15 minutes' worth) of energy are applied thinly across the entire face, the temperature of the dermis layer does not reach the critical point. We recommend 300 shots for intensive improvement in specific areas and 600 shots for fundamental reconstruction of elasticity across the entire face. 4. Key Information: Cost, Events, and Post-Procedure Care ✅ Density Lifting Procedure Costs and Events ✔️ [Monthly Benefit] Density + Customized Skin Booster Package ➡️ [Go to Detail Page] https://www.maypureclinic.com/community/events/126138685 ✔️ Includes the cost of 'Custom Vector Design' tailored to individual skin thickness and fat volume ✅ Post-Procedure Care to Boost Treatment Effects by 200% ✔️ Moisturizing and Regeneration: You may experience dryness as a thermal reaction occurs in the dermis layer after the procedure. Please apply a sufficient amount of regenerating cream and moisturizing cream. ✔️ Maintain Temperature: The heat sensation generated after the procedure helps with collagen regeneration, so it is recommended to avoid cold packs or excessive cooling for one week. ✔️ UV Protection: Please apply sunscreen thoroughly when going outdoors to prevent hyperpigmentation. 🩺 [Expert's Final Summary] There is no single right answer, such as "600 shots unconditionally" or "300 shots for the best value." The important thing is to accurately diagnose the energy (Joules) your skin truly needs. We look forward to seeing you at the Sunae May Pure Clinic consultation room.
