6 Ingredients You Should And Shouldn't Mix With Vitamin C

3 Ingredient Combinations To Avoid With Vitamin C

Are you new to skincare? Or maybe you want to take your existing skincare routine to the next level? Either way, be ready for a fun chemistry lesson. All the ingredients in your creams, masks, and serums must complement each other for the best results. 

Vitamin C is a magical skincare ingredient with a plethora of benefits for everyone. But, be careful when mixing vitamin C with other skin-loving ingredients. Mixing and layering ingredients without knowing how they work and interact with one another is a recipe for skin disaster. They may cancel out each other, rendering them useless. Or worse, causing skin dryness and irritation. Here is a guide on vitamin C dos and don'ts to get the desired results.


Skincare Ingredients to Avoid Mixing with vitamin C

You've all heard about vitamin C benefits and why you should add it to your skincare regime. It is a powerful antioxidant that repairs damaged cells, brightens dark spots, and stimulates collagen production. Applying vitamin C in the morning protects the skin from free radicals that may cause damage.

But what happens when you mix vitamin C with other skin ingredients? Vitamin C is unstable, making it difficult to combine with other skin ingredients. Skincare ingredients such as retinol and hyaluronic acid work wonders as individual products. But they may do more harm than good when combined.

Here are some common ingredients to avoid using together with vitamin C.

Vitamin C with AHAs and BHAs 

Vitamin C, AHAs (glycolic acid) and BHAs (salicylic acid) are acidic in nature. Layering them together can lower the skin pH, making it more acidic. When skin pH goes off balance, it becomes a recipe for skin irritation, redness, and peeling. To add to this, It is crucial to understand that the right pH balance of skin helps to maintain barrier functions, which in turn provide healthy and hydrated skin.

Here are three ways to layer vitamin C with AHAs and BHAs 

  • Apply them at different times of the day to reduce skin sensitivity. Use vitamin C for its sun-protective qualities and AHAs or BHAs at night to restore damaged skin.
  • Apply them on different days to help your skin adjust to the products.
  • Wait up to 30 minutes in between application to prevent diluting the ingredients.
Vitamin C and Retinol 

Retinol and vitamin C are the most potent skincare ingredients for anti-ageing. They reduce hyperpigmentation and promote collagen production for smoother, hydrated skin. These two wonder ingredients fight wrinkles for a  youthful and glowing skin. With the right pairing, this combo is effective for treating photoaging. 

Retinol is formulated at a higher pH while vitamin C at lower pH. Vitamin C works best at a pH level of 3.5 and retinol between 5.5 to 6 pH levels.

Improper layering of these two ingredients can be a recipe for disaster. Layering them can cancel out their efficacy. It can also cause adverse reactions such as skin itchiness, redness, and irritation. Partnering vitamin C and retinol can even out skin tone and improve skin texture. While vitamin C improves the appearance of fine lines, wrinkles, and dark spots, retinol increases skin elasticity. Together, it results in healthier, youthful skin.

It is best to use retinol for the PM regimen and vitamin C for the AM regimen. Also, use an SPF to prevent sun sensitivity.

The Dos: Skincare Ingredients to Combine with vitamin C

Combining vitamin C and other A-lister ingredients brings out the best in your skin appearance. It enhances the desired results.

Vitamin C + Vitamin E

Vitamin C and E are potent antioxidants, shielding the skin against UV rays and radiation. Combining both ingredients provides double ammunition to neutralize free radical damage. It boosts efficiency and results in the skin because they fight different types of UV damage. You can also layer them under your sunscreen for more protection.

Vitamin C + Hyaluronic Acid

Hyaluronic acid draws in moisture to keep the skin hydrated.  It is a naturally occurring chemical in the body that moisturizes skin, speeds wound healing and replenishes cell moisture. Hyaluronic acid works well with all skin ingredients due to its neutral pH value. Its pH level ranges between 5.0 to 8.0 while the skin has a pH value 4.5 to 6.2 making it a perfect match. You can add hyaluronic acid to every skin product to enhance its anti-wrinkle and moisturizing qualities.

Layering vitamin C and hyaluronic acid blocks any potential irritation and dryness. It results in hydrated, rejuvenated, glowing skin, free from radical damage.

Vitamin C + Niacinamide (vitamin B3)

Niacinamide, also known as vitamin B3, helps to prevent signs of ageing, improve pore appearance, and treat acne and hyperpigmentation. On the other hand, vitamin C shields against UV damage and increases collagen production to prevent wrinkles. Together with vitamin C they work perfectly to brighten skin, improve wrinkles, and skin tightness. 

A 1960s research found that mixing these two ingredients can cause inflammation. However, it was later proven that this is only possible when these two ingredients are exposed to extremely high temperatures. The scientists also found that the ingredients were not stabilized at that time.

Some forms of vitamin C such as Sodium Ascorbyl Phosphate complements niacinamide well because they share the same pH value. Niacinamide boasts of incredible benefits including strengthening the skin barrier and healing acne by balancing sebum production. It also makes pores look smaller by reducing the amount of oil produced by oily skin.

However, when mixing niacinamide and other vitamin C forms like Ethyl Ascorbic acid and L- Ascorbic Acid, be sure to leave 10-15 minutes between the applications. You can also alternate days or the time of day to apply them. Choose the best niacinamide serum for your skin type and issue for best results. 

Wrapping Up

Vitamin C is a powerhouse in your skincare routine for the best-looking skin. It firms skin, reduces black spots, and improves collagen production for youthful skin. Understanding how to mix and layer vitamin C with other A-lister ingredients is crucial for getting desired results. Check the ingredient combinations on the labels when buying skin products to get best results without any hassle.
