4 Buying Guide For Vitamin C Serum

Skin type

Needless to say, the characteristics of the skin are not the same for everyone. Therefore, everyone’s needs will be different, and those differences will control our choice of cosmetics, including vitamin C serums.

For starters, oily skin needs light, low-oil, non-comedogenic cosmetics, so gel-textured serums are ideal.

On the other hand, dry skin requires a high hydration level, so creamy serums are the right choice.

Finally, mixed skin combines fat and drier regions, so a gel intermediate texture is recommended for these.




Vitamin C serum brings multiple benefits to the skin, especially its anti-ageing power. That is why the serum is indicated for skin of a certain maturity, and its use is not recommended in young skin.

In fact, dermatology experts advise it to be used from the age of 30. Once we reach 30, we can start using serums with specific actions; for example, there are very effective anti-aging serums for more mature skin.



Currently, we can find different serums with specific properties and functions. Thanks to this variety, we can choose the serum that best suits the results we want to obtain.

If you want to reduce skin lines and aging lines that arise on your skin with age, anti-ageing serums will be your best choice as they combine vitamin C with other powerful anti-wrinkle agents, such as hyaluronic acid.

If the main problem is spots on the skin, anti-stain serums are recommended because they incorporate vitamin C and other depigmenting compounds to uniformize skin tone.

If your goal is to achieve smooth, even skin, we recommend micro exfoliant serums.




It is essential to spend a few minutes reviewing the composition of the serum before buying it.

First, because you have to look at vitamin C concentration. Concentration is beneficial when at least 8% onwards. It should be noted that excessively high concentrations (more than 20%) will not produce additional effects and are potentially irritating.

Second, you need to analyze the other ingredients in the serum. Certain serum compounds can have an irritating effect. Besides, it is essential to rule out substances at risk of allergic reactions or hypersensitivity. That will depend on the allergies that each person has and the characteristics of these.

How to use a vitamin C serum?

The most common and recommended option is to apply a vitamin C serum before leaving home or in the morning. Then you can supplement it with your usual moisturizer and sunscreen, or in any case, a sunscreen moisturizer.

But whatever you do, don’t forget sunscreen because the combination of sunscreen and a good vitamin C serum keeps your skin safe from sun damage and pollution. So it would help if you never skipped it in your morning routine.

Sure, vitamin C serum may also be part of your nighttime routine, but don’t just rely on it, as I said before.

Then, you can choose to use vitamin C in the morning, and at night, you can choose a stronger ingredient to fight skin lines. As these increase collagen production, I recommend vitamin A or retinol, strengthening skin elasticity and lighten stains caused by sun exposure.
