As collagen-stimulating treatments become increasingly popular, I frequently receive questions from patients about the differences between 'Rh Collagen Type 1' and 'Atelocollagen'. Both are excellent options for skin rejuvenation, but they work through different mechanisms and suit different skin needs. Today, I want to break down these differences simply and honestly, so you can understand what you are choosing for your skin.

Rh Collagen Type 1: The 'Stimulation' and Regeneration

Rh (Recombinant Human) Collagen Type 1 is created through advanced biotechnology, resulting in a high-purity product whose structure is 99.9% identical to the collagen naturally found in human skin. Because it matches our own collagen perfectly, it causes virtually no immune reaction. Its primary mechanism is 'Stimulation' — waking up and triggering our skin cells (fibroblasts) to synthesize new collagen by themselves continuously. This increases skin elasticity and moisture from within.

Atelocollagen: หรือ 'คอลลาเจนสด' เด่นเรื่องการ 'เติมเต็ม' เพื่อผิวอิ่มฟู

Atelocollagen is a highly purified form of collagen, often referred to as 'fresh collagen' (คอลลาเจนสด). By removing the 'telopeptides' (the parts that typically cause allergic reactions), it becomes highly safe for human use. Atelocollagen excels at providing immediate 'Volume' (filling) due to its highly elastic texture and exceptional water retention properties. It plumps, firms, and smoothens the skin surface almost immediately after treatment.

How to Choose the Right One for Your Skin?

To help you choose, I have summarized how they are applied in clinical practice to match specific concerns:

  • Rh Collagen Type 1 is ideal for: Long-term structural skin restoration, active skin cell stimulation, reducing fine lines, and improving overall skin quality and elasticity.
  • Atelocollagen is ideal for: Filling deep creases and indentations, plumping skin structure, and stimulating new tissue regeneration to look naturally fuller without altering your original facial shape.

Honest Summary from our doctor

Neither is strictly 'better' than the other; it depends on your skin's current needs. If your skin is thinning, losing elasticity, and you want to focus on rebuilding your skin structure, Rh Collagen Type 1 is a fantastic choice. If your skin feels dry, tired, and you want a quick boost in hydration and plumpness, Atelocollagen might be the right answer. In some treatment plans, we can even design a protocol that utilizes the benefits of both over time.

Frequently Asked Questions

Are they safe? +
Yes, both are highly safe. Rh Collagen is bio-identical, so the allergy risk is extremely low. Atelocollagen has the allergy-causing components (telopeptides) removed, making it very safe as well.
How long do the results last? +
Results typically last between 6 to 12 months, depending on your lifestyle and skin condition. Rh Collagen often has longer-lasting structural benefits because it stimulates your own collagen production, while Atelocollagen provides wonderful medium-term hydration. For the most visible and lasting results, I recommend an initial protocol of 2-3 sessions, spaced 1 month apart.
Which one should I choose? +
The best way is to have an in-person consultation. I will assess your skin quality, hydration levels, and signs of aging to recommend the most honest and effective option for you.
