A combination of Hydration Boosters, Allantoin, 10% Vitamin C, and 1% Glutathione, this solution works to improve the appearance of your skin. Not only did Dr. Megha notice the ingredient combination, but she was also impressed by the serum's non-oxidizing Vitamin C blend and its lightweight, non-sticky texture.

Dr. Megha Sharma considers this serum suitable for a range of skin types, including normal, dry, combination, and oily skin.

What Dr. Sharma Likes About Foxtale Vitamin C Serum 

Vitamin C serums help a lot of Dr. Sharma's patients who aren't aiming for flawless skin. Whether it's a lifeless skin tone, uneven pigmentation, dark patches, or acne scars, these issues are usually addressed. Vitamin C serums can be particularly relevant when you're looking to improve the appearance of pigmentation and dark spots. 
 

The serum is positioned to improve the appearance of dullness and support a brighter-looking complexion. With the beneficial properties of their blend, including hydration boosters, Allantoin, 10% vitamin C, and 1% glutathione, to improve skin tone and luminosity without drying it out. 

1. Non-oxidising Vitamin C

Dr. Megha highlights the serum's non-oxidising Vitamin C formula as one of its key features. For people who are cautious about using Vitamin C, the formulation is designed to offer greater stability. Dr. Megha considers this a useful feature for sensitive skin, while the lightweight texture also makes the serum easy to incorporate into normal, dry, combination, and oily skin routines. 
 

Foxtale 10% Vitamin C Glutathione Advanced Brightening Serum is a better option for individuals who have experienced side effects with stronger Vitamin C serums due to its non-oxidizing nature and its focus on Vitamin C stability.
 

2. 1% Glutathione 

The serum contains 1% Glutathione, a concentration Dr. highlights as higher than what is commonly found in many Vitamin C serums on the market. Since glutathione is an antioxidant that acts in combination with vitamin C, and considering that it is present in a significant concentration (rather than as a mere ingredient) in this formulation, she regarded it well.

3. Allantoin for Balance

Since skin might be more sensitive to brightening actives, she appreciates the use of Allantoin. The formula also contains Allantoin alongside hydration boosters, helping complement its brightening-focused ingredients and maintain a comfortable skin feel.
 

4. The Skin-Factor Assessment

A serum's texture is more important than most people realize; it might be the deciding factor in whether or not you use it daily. According to Dr. Sharma's assessment, this one is relevant because: 

What Is the Texture of Foxtale Vitamin C Serum Like?

• Lightweight
• Non-sticky
• Fast-absorbing
• Hydrating
• Dewy finish

This texture can work particularly well for combination and oily skin that prefers lightweight layers, while the hydrating feel can also suit normal and dry skin. The dewy finish may be especially appealing if your skin tends to look dull or dehydrated.

As it dries, it doesn't leave behind any sticky residue and turns into a healthy, smooth finish instead of a greasy shine. So it's perfect for a morning routine, immediately before applying sunscreen. Learn more about when to apply Vitamin C serum and how to build it into your AM or PM routine.

Foxtale also provides safety and efficacy documentation for the product, which adds supporting information beyond the product's ingredient and benefit claims.

Wondering how to use Vitamin C serum without overcomplicating your skincare routine? The basic order is simple: cleanse, apply Vitamin C serum, moisturise, and finish with sunscreen in the morning.

Used consistently, Vitamin C can help improve the appearance of dullness, uneven skin tone, and pigmentation while providing antioxidant support. Here's exactly how to add it to your routine.

Vitamin C Serum Benefits: Why Use It?

Vitamin C is best known for its antioxidant and brightening properties. It helps protect skin from oxidative stress caused by environmental factors while supporting a more even-looking skin tone.

With regular use, a Vitamin C serum can help:

• Brighten dull-looking skin
• Improve the appearance of uneven skin tone
• Reduce the appearance of dark spots and pigmentation
• Support collagen production
• Protect skin from environmental oxidative stress

How to Use Vitamin C Serum on Your Face

Follow this simple Vitamin C serum application order:

Step 1: Cleanse

Start with a gentle cleanser to remove oil, dirt, sunscreen, and other buildup. Pat your face dry before applying your serum.

For a brightening-focused routine, you can use Foxtale's Vitamin C Face Wash.

Step 2: Apply Vitamin C Serum

Apply 2–3 drops of Vitamin C serum to your face and gently spread it across your skin. Avoid vigorous rubbing.

Foxtale's 10% Vitamin C + Glutathione Serum combines Vitamin C with Glutathione to target dullness and uneven-looking skin.

Step 3: Moisturise

Follow your serum with a moisturiser to hydrate your skin and support the skin barrier. If your skin is sensitive or prone to dryness, this step is particularly important.

You can layer it with Foxtale's Vitamin C Moisturizer.

Step 4: Finish With Sunscreen

If you're using Vitamin C in the morning, sunscreen is the final step. Vitamin C does not replace SPF. A broad-spectrum sunscreen helps protect your skin from UV exposure that can contribute to tanning, pigmentation, and premature skin ageing.

Try Foxtale's Glow Sunscreen SPF 50 PA++++ as the final step of your morning routine.

At night, simply skip sunscreen.

Vitamin C Serum Morning or Night: When Should You Apply It?

Morning is a convenient time to use Vitamin C serum because its antioxidant properties complement your daytime sunscreen routine.

However, can Vitamin C serum be used at night? Yes. You can use it at night after cleansing and before moisturiser, provided the product's instructions allow it.

The most important factor is consistency, not choosing a perfect time of day.

How Often Should You Use Vitamin C Serum?

If you're new to Vitamin C, start a few times a week and gradually increase frequency as your skin adjusts. If your skin tolerates the product well, many Vitamin C formulations can be used daily.

Always follow the usage instructions of your specific serum. 

How Many Drops of Vitamin C Serum Should You Use?

For most face serums, 2–3 drops are enough for the entire face. Using more doesn't necessarily mean faster results and may increase the chances of irritation.

Before introducing a new Vitamin C product, patch test it, especially if you have sensitive skin or are new to active ingredients.

Common Vitamin C Serum Mistakes to Avoid

A few simple habits can make your routine more effective:

• Using too much serum: More product doesn't mean faster results.
• Skipping sunscreen: Vitamin C isn't a replacement for SPF.
• Introducing too many actives at once: Give your skin time to adjust.
• Ignoring irritation: Persistent burning, redness, or discomfort is a sign to stop and reassess your routine.
• Being inconsistent: Skincare works best when you follow a routine consistently.

How Long Does Vitamin C Serum Take to Work?

Results vary depending on the Vitamin C formulation, concentration, skin concern, and consistency of use. You may notice improvements in skin brightness and overall appearance with regular use, while pigmentation and uneven skin tone can take longer.

Give your serum time to work rather than increasing the amount or frequency.

The Bottom Line

How to use Vitamin C serum? Keep it simple: cleanse, apply 2–3 drops of serum, moisturise, and finish with sunscreen in the morning. Start slowly if you're new to active ingredients and stay consistent. The right formula, regular application, and daily sun protection matter more than using a complicated routine.

Vitamin C is an antioxidant recognized for its brightening effects and is a staple in skincare. It helps to enhance the appearance of dullness, dark spots, and uneven-looking skin, while boosting collagen formation. However, what the best Vitamin C serum is for you will depend on your skin type, problems, the kind of Vitamin C, and your skin’s tolerance.

If you are searching for a Vitamin C serum for oily skin, dry skin, or sensitive skin, the trick is to find a product that feels good enough to use regularly. You can also learn more about the benefits of Vitamin C serum before adding it to your routine.

Vitamin C Serum for Different Skin Types 

1. Vitamin C Serum for Oily Skin: 

If you have oily skin, choose a Vitamin C serum for oily skin with a lightweight, non-greasy feel. Vitamin C itself is not greasy or pore-clogging, but the entire composition might impact the feel on the skin. 

Look for:

• Lightweight, water-based textures
• Non-greasy formulas
• Stable Vitamin C derivatives
• Hydrating ingredients such as Hyaluronic Acid
• Supporting ingredients such as Niacinamide

Is Vitamin C serum good for oily skin? Yes. A lightweight formulation can fit comfortably into an oil-control skincare routine.

2. Vitamin C Serum for Dry Skin:

Vitamin C for dry skin can be helpful when combined with moisturizing and barrier-supporting ingredients. Look for formulas containing: 

• Hyaluronic Acid
• Glycerin
• Ceramides
• Panthenol
• Squalane

If you have dry or sensitive skin, don’t choose a product just based on high Vitamin C concentration. Follow your serum with an appropriate moisturizer to help lock in moisture. 

3. Vitamin C Serum for Sensitive Skin:

Formulations with a high acidic content may irritate sensitive skin more easily. If you have sensitive skin and want a Vitamin C serum, choose a lower dose or a milder Vitamin C derivative. 

Choose:

• Gentle Vitamin C derivatives
• Lower concentrations when starting
• Fragrance-free formulas
• Hydrating and soothing ingredients

Patch testing and introducing the serum gradually can also help you assess your skin's tolerance. 

4. Vitamin C Serum for Combination Skin:

A good option is a mild yet moisturizing vitamin C serum for combination skin, as combination skin has both oily and dry patches. This approach can help you feel more confident and cared for in your skincare routine.
 

Choose a non-greasy texture & look for moisturizing elements like glycerin or Hyaluronic Acid. If you have regions of your face that are more sensitive than others, pick a solution that your skin can handle pleasantly on those spots. Making informed choices can help you feel empowered in your skincare routine. 

5. Vitamin C Serum for Acne-Prone Skin 

If you have acne-prone skin, choose a lightweight Vitamin C serum that complements your existing routine. Vitamin C may be particularly relevant if you're concerned about the appearance of post-acne marks and uneven-looking skin tone.

Avoid introducing several strong actives at the same time, and always patch test if you're trying a new product. 

How to Choose the Best Vitamin C Serum

When choosing a Vitamin C serum, consider these four factors:

1. Choose the Right Vitamin C

L-ascorbic acid is the most researched type of topical vitamin C. Other derivatives like Magnesium Ascorbyl Phosphate, Sodium Ascorbyl Phosphate, and Tetrahexyldecyl Ascorbate are also utilized in skin care products depending on the stability and formulation needs.
 

2. Don’t Aim for the Highest Percentage

More Vit C concentration does not mean it’s better. The optimal concentration depends on the type of Vitamin C, the overall formula, and your skin tolerance. If you’re new to this or have sensitive skin, you might want to opt for a softer recipe.
 

3. Think About The Packaging

Some C vitamins are sensitive to light and oxygen. Packaging that reduces exposure to these elements can assist in maintaining formula stability. 

4. Choose Based on Your Skin Concern 

What Percentage of Vitamin C Is Best? 

There is no optimal concentration because every person is different. What works best for your skin is a combination of the vitamin C derivative, formulation, and concentration. 
 

If you're looking for a 10% option, explore Foxtale's 10% Vitamin C + Glutathione Advanced Brightening Serum. 

How to Use Vitamin C Serum

A simple Vitamin C skincare routine can follow this order:

1. Cleanse your face with a gentle cleanser.
2. Apply a few drops of Vitamin C serum to clean skin.
3. Allow it to absorb.
4. Follow with moisturizer if needed.
5. Apply broad-spectrum sunscreen during the day.

Because of its antioxidant effects, vitamin C is often included in morning routines. Applying sunscreen every day is still the best way to shield your skin from harmful UV rays.

Choose the correct vitamin C product and concentration for your skin type, ease into it if necessary, and remember to use sunscreen every day. 

Korean glass skin refers to skin that appears intensely hydrated, smooth, even-toned, and naturally luminous. The skin appears reflective. It is not about using makeup or filters to achieve the results. Glass skin is about improving your skin quality for a healthy glow.

You may notice that interest in glass skin has surged over the years. Many want skin that appears fresh without heavy makeup. The focus has changed to hydration balance, barrier health, and long-term skin function.

This guide explains how to achieve Korean glass skin and how to adapt the approach for Indian skin and climate.

What is Glass Skin?

So, how to achieve glass skin? Glass skin is not a genetic trait or a result of using a single product. It requires:

• Optimal hydration levels
• A strong skin barrier
• Oil control
• Even texture and tone
• Sun protection

How to Get Korean Glass Skin

Let’s understand how to get Korean glass skin at home. You can achieve Korean glass skin by improving skin hydration and barrier health. Your skin appears glossy and clear when the outermost skin layer (stratum corneum) holds water and reflects light evenly.

Below is a climate-appropriate Korean glass skin routine.

The Two-Step Cleanse

Clear and reflective skin begins with proper cleansing.

Why does double cleansing work?

• Oil-based cleansers dissolve sunscreen, excess sebum, and makeup
• Water-based cleansers remove sweat, dirt, and residual debris
• Prevents clogged pores and dullness

Follow with a glow-supporting cleanser, such as a Detan face wash. A good cleanser removes impurities and also preserves lipids essential for barrier function. Glass skin requires clean skin to begin with.

Prep with the Glow Toner

Toner is misunderstood by many. It is not about restoring hydration in your skin.

What does a good toner do?

• Replenishes water lost during cleansing
• Supports barrier recovery
• Improves absorption of serums
• Helps skin reflect light more evenly

Using a hydrating formula, such as a Glow toner, provides humectants that attract moisture into the skin.

Layer Your Hydration

Serums are meant for targeted improvements in skin tone and radiance.

Remember that ingredient quality matters more than the number of products when you are looking to achieve Korean glass skin.

The active ingredients that support glass skin are listed below.
