You would have often heard of the terms “antioxidants” and “free radicals” in skincare. But what do they mean? Antioxidants are one of the most critical ingredients in skincare. They help protect the skin against environmental factors and can even prevent signs of ageing. This article will explain what antioxidants are, how they work, why they’re crucial for your health and beauty routine, and the benefits of using an antioxidant face serum.

What is an antioxidant?

Antioxidants are a class of molecules that fight free radicals. Free radicals are unstable oxygen molecules that form when your body breaks down food or reacts to environmental damage. When free radicals form, they can cause damage to cells and tissues by interacting with DNA and other cellular structures.

Antioxidants may be found in plants or animals but are also artificial (synthetic). They’re equally effective at protecting your skin from environmental stressors regardless of whether they come from nature or a lab.

What do antioxidants do for your skin?

Antioxidants have been shown to protect the skin from damage caused by free radicals, which can cause oxidative stress and accelerate ageing. They also help slow down this process by neutralising these harmful molecules before they can do any damage. Antioxidants are essential when preventing sun damage since they can help reduce UV-induced skin cancer risk and prevent signs of ageing like fine lines and wrinkles. In addition, antioxidants may help treat acne by reducing inflammation.

Vitamin C and E are common antioxidants.

Antioxidants are chemicals found in your body, as well as in the food you eat. Your body uses antioxidants to repair damage caused by free radicals. Free radicals are atoms or molecules with unpaired electrons, making them unstable. They can cause damage in your cells and lead to cellular ageing (this is why antioxidants protect against sun damage).

Antioxidant vitamins include vitamin A (retinol), vitamin C (ascorbic acid), beta-carotene, vitamin E, selenium, zinc, glutathione, coenzyme Q10 (CoQ10) or ubiquinone, which helps produce energy at a cellular level. You can get all these vitamins from food sources such as fruits and vegetables, but some people might need extra help getting the right amount of antioxidants through supplements since they may not get enough through diet alone.

Why use an antioxidant face serum?

Antioxidants are the main ingredient in many skincare products, so it’s important to know what they do and why everyone is talking about them. Antioxidants help prevent skin damage from environmental factors such as UV rays, pollution and smoke – which can all cause your skin to age prematurely. They also protect your skin from free radicals – unstable molecules that attack healthy cells in the body when there’s an abundance of them.

Antioxidants can improve the look and feel of your skin by fighting wrinkles, acne breakouts, redness and dryness. The suitable antioxidant serum may even help you treat eczema or psoriasis.

Purchasing an antioxidants serum

Here are some tips on how to use an antioxidant serum:

  • Apply it twice a day, morning and night.
  • Use the right amount for your skin type. For example, if you have oily or combination skin, apply less than usual because serums are often heavier than moisturisers or cleansers in terms of consistency. If you have dry or normal skin types, apply more so that the product can be absorbed into the pores better. After applying the serum for extra absorption, you can also opt for a toner.
  • Keep in mind that not all antioxidants will work for everyone—it’s essential to find an ingredient that works well with your specific needs (if any) before purchasing anything new.


Antioxidants are a great way to keep your skin looking young and healthy. They help protect it from free radicals that can cause damage and make you look older. An antioxidant face serum is recommended as part of your daily skincare routine.
