Does Vitamin C Serum Actually Work? Tried & Tested with PHD

It is not hard to find a solution to your skin in the world of skincare products, but Vitamin C serum has taken its seat among the products which are mostly recommended by professionals and everyday skincare connoisseurs. However, with increasing products entering the market all the time, a real question is presented:

Or is Vitamin C serum just another beauty trend?

In order to respond to this, we did more research on the science behind Vitamin C and tried one of the most promising products within the Indian skincare market – PHD Beauty 10% Vitamin C Brightening Serum. This is what we found out.

What Is Vitamin C and Why Is It Used in Skincare?

3-O-Ethyl Ascorbic Acid (Vitamin C) is an antioxidant compound made of water solvents; it is another important factor to keep the skin healthy. When used as a serum it has several advantages above and beyond clearing up the complexion.

Key Benefits of Vitamin C in Skincare:

Reduces pigmentation and fades dark spots
Boosts collagen production to reduce fine lines
Protects against free radical damage caused by UV rays and pollution
Improves overall skin tone and texture
Helps heal acne scars and post-inflammatory hyperpigmentation

These scientifically backed advantages have made Vitamin C one of the most trusted actives in skincare globally.

Does Vitamin C Serum Actually Deliver Results?

The effectiveness of a Vitamin C serum depends on several key factors:

Form of Vitamin C used (3-O-Ethyl Ascorbic Acid vs. stable derivatives)
Concentration (10–20% is considered optimal)
Presence of stabilizers and boosters like Ferulic Acid
Packaging (Dark bottles protect the formula from oxidation)
Consistency of use and sun protection

Clinical Studies Show:

Vitamin C significantly reduces pigmentation and improves skin clarity within 4 to 8 weeks of regular use.
It neutralizes oxidative stress in the skin, reducing visible signs of aging.
When paired with sunscreen, it boosts skin protection against UV damage.

Hence, yes—Vitamin C serum does work, provided the formulation is right and used consistently.
