Maintaining beautiful skin requires a comprehensive approach, both from the inside and the outside. In the world of aesthetics and beauty, there are many ways to preserve skin health and appearance, one of which is ensuring the skin receives adequate Vitamin C. Vitamin C, also known as ascorbic acid, is an active ingredient that plays an important role in protecting the skin from the harmful effects of free radicals.

The skin’s Vitamin C needs can be supported through the consumption of fruits such as strawberries, cantaloupe, guava, papaya, and others. Consuming these fruits helps maintain overall body health while nourishing the skin from within. However, maintaining optimal skin health also requires external care. In the field of skincare, Vitamin C is commonly applied through specially formulated serums designed for skin treatment.

Some of the benefits of using a Vitamin C serum include:


  • Brighter-Looking Skin
    Helps reduce the appearance of dark spots and promotes a more even and radiant skin tone.
  • Improved Skin Elasticity
    Supports collagen production, helping the skin appear firmer while reducing visible signs of aging.
  • Antioxidant Protection
    Helps protect the skin from damage caused by free radicals.

To maintain healthy and radiant skin, it is important to meet the skin’s needs by regularly using a Vitamin C serum. Consistent use of a Vitamin C serum can provide both protection and optimal skin care. Therefore, choosing the right Vitamin C serum is an important step, such as Professional-C by OBAGI Medical, which is formulated to help maintain healthy and radiant-looking skin.

Getting to Know Professional-C by OBAGI Medical

OBAGI Medical, which will soon be available in Indonesia, offers an effective way to support the skin’s Vitamin C needs through the Professional-C Serum. Formulated with L-ascorbic acid, a form of Vitamin C considered the gold standard in skincare, this serum features an optimally designed pH level to maintain formula stability while enhancing absorption and effectiveness in the skin.

Professional-C is designed to help care for skin that shows early signs of aging caused by environmental factors such as sun exposure and pollution. The serum helps improve the appearance of photoaging, uneven skin texture, and dull-looking skin while also providing protection against further environmental damage. With daily use, Professional-C helps support healthier and more radiant-looking skin.


To accommodate different skin needs and conditions, Professional-C Serum is available in three concentrations:

1. Professional-C Serum 10%
Formulated with 10% bioavailable L-ascorbic acid, this concentration is suitable for dry and sensitive skin. The inclusion of propylene carbonate helps stabilize L-ascorbic acid, ensuring that Vitamin C remains effective and evenly distributed on the skin. The gentle formula provides benefits while minimizing the risk of irritation.

2. Professional-C Serum 15%
This serum contains 15% bioavailable L-ascorbic acid, making it suitable for normal skin types. The formula is enriched with ascorbyl glucoside, an ingredient that helps maintain Vitamin C stability so its antioxidant benefits can work more effectively in supporting skin health.

3. Professional-C Serum 20%
This concentration contains 20% bioavailable L-ascorbic acid, making it ideal for oily skin. The formula includes propylene carbonate to maintain Vitamin C stability, as well as sodium hyaluronate to help maintain skin hydration without leaving a heavy feeling on the skin.

More Than Just a Vitamin C

Professional-C Serum is formulated with a low pH level that has been proven to help maintain Vitamin C stability, ensuring that product quality remains preserved for a longer period. The formula is designed to begin penetrating the skin immediately after application, allowing Vitamin C to be effectively absorbed and retained within the skin layers for optimal benefits.

In addition, a specialized process known as Nitrogen Blanketing is used to protect the serum by minimizing oxygen exposure. This process helps preserve the effectiveness of Vitamin C while extending the product’s shelf life.


Professional-C not only functions as an antioxidant to help brighten the skin, but is also specially formulated to remain stable, absorb easily, and work effectively within the skin. With high-quality L-ascorbic acid, multiple concentration options tailored to different skin types, and advanced formulation technology that preserves Vitamin C quality, Professional-C provides comprehensive care to help keep the skin healthy, protected, and radiant.

With regular use, Professional-C can become an essential part of a daily skincare routine to maintain optimal skin condition. Professional-C will soon be available at selected aesthetic clinics through idsMED Aesthetics, making it easier for you to access professional-grade Vitamin C skincare.
