Stabilized Vitamin C (Natural-C Glycol™) Serum Information

Here is the information regarding the Stabilized Vitamin C (Natural-C Glycol™) Serum based on your questions:

1. pH Level and Irritation

The Stabilized Vitamin C (Natural-C Glycol™) Serum has a pH in the range of 2-3. The low pH is characteristic of L-Ascorbic Acid formulations and can cause a temporary tingling sensation upon application. This sensation is different from the direct irritation and exfoliation caused by ingredients like AHA/BHA.

Since you mentioned that you do not typically experience irritation from using AHA/BHA, your skin likely has a good tolerance for acidic products. Therefore, you are less likely to find this vitamin C serum irritating. However, skin reactions can vary, so it is always recommended to test the product on a small area first.

2. Sufficiency for Oily Skin

Whether this serum is sufficient as a single main skincare product for your oily skin depends on your specific skin concerns and goals. The serum is effective for benefits associated with Vitamin C, such as brightening the skin and reducing dark spots.

For oily skin, using this serum at night is generally suitable. For daytime use before sunscreen, it can provide antioxidant benefits and help the skin tolerate sun exposure better. However, you should observe how your skin feels with the combined texture of the serum and sunscreen to ensure it is not too heavy or oily for your preference during the day. Some individuals with oily skin may also benefit from incorporating products specifically designed to balance oil production during their daytime routine.
