Subcision is a medical procedure that helps release rigid fibrous bands beneath the skin. This method facilitates the natural filling of pitted scars. However, the doctor's technique only contributes about 50% to the success of the entire treatment. The remaining 50% depends entirely on the at-home recovery process. Incorrect skin care during the micro-injury stage can easily lead to post-inflammatory hyperpigmentation (PIH), infection, or even the recurrence of new fibrous scars.

The skin after the procedure requires a scientific care regimen according to each recovery milestone. Understanding the mechanism of injury, eliminating common mistakes, and promptly supplementing epidermal regenerating active ingredients will help shorten healing time and optimize collagen proliferation density.

1. What is subcision? Why is proper post-treatment care necessary?

To properly recover and care for your skin after subcision, you first need to understand the nature of this method.

1.1. Mechanism of the subcision method

Subcision is a minimally invasive procedure. The doctor uses a specialized medical needle to penetrate the skin's surface. The needle tip moves back and forth to sever the rigid fibrous bands that adhere tightly from the dermis to the hypodermis.

These fibrous tethers are the cause of the skin's surface being pulled down, forming stubborn pitted scars. When the fibrous bands are cut, releasing the surface, the skin will have space to gradually push up. At the same time, this action creates a simulated injury signal. The body immediately activates a self-healing response, concentrating fibroblasts to synthesize new Collagen and Elastin to fill the empty space.

1.2. What happens to the skin after subcision?

Simply put, at this point, your skin has just undergone a controlled micro-injury. Microvascular damage appears in the dermis, causing slight bleeding under the skin. Swelling, bruising, and physiological inflammatory reactions appear immediately.

This is a completely normal reaction. However, if this inflammatory reaction is prolonged excessively, or if the skin's protective barrier is invaded by bacteria, collagen proliferation will be hindered. Worse, you risk facing post-inflammatory hyperpigmentation or the formation of new fibrous scars. The doctor creates a perfect wound, but you are the one who decides whether that wound will heal into smooth skin or another pitted scar tissue.

2. Post-subcision skin care guide by stage

Each healing stage requires a specific care regimen. You cannot apply the same formula for the first day and the third week.

 2.1. First 24 hours: Absolute protection

At this time, the needle marks on the skin are still open. Absolutely do not touch your face. Your hands contain countless harmful bacteria.

Do not wear makeup. Do not apply any regular skincare products. Do not wash your face with cleansing facial wash. You should only use physiological saline to gently cleanse if instructed by a doctor.

2.2. First 2-3 days: Soothing and inflammation control

The skin begins to close the micro-injuries but is still red and slightly bruised. You need to prioritize products that can soothe and reduce stinging sensations.

Avoid hot compresses as heat will increase swelling and bruising. Do not engage in heavy sports that cause sweating. Sweat accumulating on open wounds can easily lead to infection.

2.3. Days 4-7: Enhanced recovery and barrier reinforcement

At this time, the needle marks begin to form tiny scabs. Transepidermal water loss increases sharply, making the skin feel dry and tight.

You need to focus on strengthening the skin's protective barrier. Immediately supplement with deeply hydrating ingredients and those that support epidermal regeneration. Do not peel off these scabs with your hands.

2.4. After 1-4 weeks: Strict sun protection and structural maintenance

This is the stage when fibroblasts are most active in regenerating collagen. However, the newly formed skin layer is extremely sensitive to sunlight.

UV rays will stimulate melanocyte cells to produce melanin, causing dark spots at the exact location of the freshly subcised scar. Use broad-spectrum SPF50+ PA++++ sunscreen daily. At the same time, combine essences that support long-term skin matrix restructuring.

3. Mistakes that reduce the effectiveness of subcision

Many people spend tens of millions of VND on treatment, but the results are not as desired simply because they fall into the following mistakes:

• Exfoliating too soon: Using AHA, BHA, or mechanical scrub beads when the skin has not fully recovered will tear the delicate new epidermis.

• Using Retinol or Tretinoin at the wrong time: Strong treatment actives will increase physiological inflammatory reactions, prolonging redness and swelling.

• Neglecting sun protection: Not applying enough sunscreen turns bruised scars into stubborn PIH dark spots.

• Picking, peeling scabs: Using hands to pull off scabs scratches the healing skin tissue, easily leading to new depressed scars.

• Detoxing the skin by squeezing pimples: Applying pressure to the recently treated area breaks the microvessels that are regenerating under the skin.

4. Why is recovery serum a must-have step after subcision?

After invasive procedures, the skin's ability to retain moisture significantly decreases. The lipid layer on the surface is disrupted. A quality recovery serum acts as a "scaffolding" to help the skin repair itself.

1. Supports epidermal regeneration: Provides growth signals that help new skin cells migrate and fill in damage quickly.

2. Reduces prolonged inflammatory reactions: Controls redness and burning, helping the skin return to a balanced state.

3. Reduces transepidermal water loss (TEWL): Creates a moisture-retaining barrier, allowing biological reactions under the skin to occur in an ideal moist environment.

4. Promotes collagen proliferation: Provides raw materials for fibroblasts to produce standard collagen, avoiding recurrent fibrosis.

5. Reduces the risk of post-inflammatory hyperpigmentation (PIH): Soothes overactive responses of melanocyte cells.

5. oh!oh!'s comprehensive recovery duo to optimize the recovery process after subcision

Recognizing the need for intensive skin recovery after invasive treatments, oh!oh! has researched and developed a product duo that fully meets the skin's healing process.

5.1. oh!oh! Oatmere Serum - Restores skin foundation and strengthens the protective barrier

After severing the fibrous bands, the skin needs immediate soothing to calm inflammatory reactions. oh!oh! Oatmere Serum is specifically designed for this purpose.

The product boasts a superior multi-layer recovery ingredient list. EGF growth factor combined with Oat extract helps soothe redness and stinging sensations immediately after application. Supplemented with Centellosides, Pro Anti-Irritant Complex, and Hyaluronic Acid (HA), the serum quickly fills in areas of dehydration, strengthening the damaged lipid barrier. The skin becomes moist and smooth, significantly reducing dryness and tightness. This is a perfect primer for sensitive skin after the procedure.

5.2. oh!oh! Flawless Abyss Serum - Used during the scar improvement and skin surface restructuring phase

Once the skin has passed the acute inflammatory phase, the next important task is to shape the scar filling structure. oh!oh! Flawless Abyss Serum plays a supporting role during this stage.

The product helps improve uneven skin surface areas. Peptides and specialized nutrients help create an ideal healing environment. As a result, the natural collagen production process at the bottom of the scar proceeds smoothly. The product contributes to maintaining smoothness, reducing the risk of new unsightly fibrous scars forming when combined with a medically approved care regimen.

5.3. Why should Oatmere Serum and Flawless Abyss Serum be combined?

The two products create a closed recovery cycle, clearly divided according to each recovery milestone of the skin.

Oatmere Serum plays the role of building a "healthy skin foundation," calming inflammatory flare-ups and locking in moisture. Flawless Abyss Serum supports the restructuring process, helping the skin surface become smoother. Combining this duo helps you optimize the treatment results created by the subcision doctor.

6. Conclusion

The subcision procedure helps flatten depressed scars on the face. But it is the at-home care routine that determines whether you can maintain that result.

Always prioritize minimalist care steps: soothing, hydrating, strengthening the protective barrier, supporting restructuring, and thorough sun protection. The presence of the duo oh!oh! Oatmere Serum and oh!oh! Flawless Abyss Serum is a comprehensive support solution, bringing peace of mind to the skin throughout the recovery journey.
