Is Vitamin C Serum Making Your Skin Dry? Here's Why And What To Do

Vitamin C serum is a beloved staple in many skincare routines, known for its brightening, anti-ageing, and antioxidant properties. However, some users experience unexpected dryness after incorporating it into their regimen. If you’re facing this issue, don’t worry, you’re not alone. 

In an exclusive interaction with the editorial team of Onlymyhealth, Dr Sanjeev Gulati, Department of Dermatology, Sharda Hospital - Noida, helped us explore why this happens and how you can continue to enjoy the benefits of Vitamin C serum without dryness.

Why Does Vitamin C Serum Cause Dryness?

1. High Acidity and pH Levels
   Vitamin C, particularly in its purest form (L-ascorbic acid), is highly acidic. This low pH can disrupt your skin’s natural barrier, leading to moisture loss and dryness.

2. Alcohol-Based Formulas
   Some Vitamin C serums contain alcohol to improve absorption and shelf stability. However, alcohol can strip your skin of its natural oils, leading to dryness and irritation.

3. Overuse or Incorrect Application
   Applying Vitamin C serum too frequently or in excessive amounts can overwhelm the skin, resulting in irritation and dryness. It's best to start with a lower concentration and gradually increase usage.

1. Combination With Other Harsh Ingredients
   If you’re using Vitamin C alongside strong exfoliants like AHAs, BHAs, or retinoids, your skin may become overly sensitive and dry.

2. Underlying Skin Type and Sensitivity
   Those with naturally dry or sensitive skin may find that Vitamin C serums exacerbate their condition. Choosing the right formulation is key to avoiding irritation.

How to Prevent and Treat Dryness

1. Choose a Gentle, Hydrating Formula
   Opt for serums that contain Vitamin C derivatives like sodium ascorbyl phosphate or magnesium ascorbyl phosphate, which are less acidic and gentler on the skin.

2. Look for Added Moisturising Ingredients
   Serums that include hyaluronic acid, glycerin, or aloe vera can help counteract dryness while delivering Vitamin C benefits.

3. Layer With a Good Moisturiser
   Always follow up with a hydrating moisturiser to lock in moisture and strengthen the skin barrier.

1. Reduce Frequency of Use
   If you’re experiencing dryness, try using Vitamin C serum every other day or a few times a week instead of daily.

2. Apply to Damp Skin
   Applying Vitamin C serum to slightly damp skin can enhance absorption and minimise potential irritation.

3. Use Sunscreen Daily
   Vitamin C makes your skin more sensitive to sunlight, so always follow up with a broad-spectrum sunscreen to prevent further damage and dryness.
