1. Introduction
Due to the naked nature of human skin, it is continuously exposed to external factors such as sunlight, air pollution, other environmental pollutants, mechanical and chemical assaults, and other factors that can cause the production of free radicals. Unstable atoms known as free radicals have the potential to harm bodily cells. Why are they so erratic? These are molecules that include oxygen and one unpaired electron. They may easily interact with other molecules thanks to that one electron, but that isn’t necessarily a good thing.
These molecules can set off an extensive series of chemical events in the body known as oxidation, which can be harmful and lead to aging symptoms. Free radicals change the chemical structures of DNA and proteins in cells, causing damage.
2.From where do they originate?
Causes of Free Radicals:
A)Biological Processes:
- Free radicals are naturally generated within the body through various biological processes.
B)External Sources:
- Stress: High levels of stress can contribute to the production of free radicals.
- Hectic Lifestyle: A fast-paced and demanding lifestyle may increase the generation of free radicals.
- Poor Eating and Drinking: Unhealthy dietary habits and excessive alcohol consumption can be sources of free radicals.
- Drugs: Both legal and illicit substances can contribute to the formation of free radicals in the body.
- Illness: Certain health conditions and diseases may lead to an increased presence of free radicals.
- Pregnancy: The body undergoes changes during pregnancy that can influence the production of free radicals.
- Sunlight Penetration: Overexposure to UV light from the sun is a significant external source of free radicals.
- Pollution: Environmental pollutants can contribute to the formation of free radicals in the body.
- Harsh Skincare Items: Certain skincare products containing aggressive ingredients may trigger the production of free radicals on the skin.
3.What harm do the body’s free radicals cause?
Oxidative stress is a result of an excess of free radicals. Chemical reactions that cause damage to our cells are called oxidation. Antioxidants are useful in this situation.
Normally, the antioxidant defenses in our bodies allow us to combat this stress. However, when the body’s ability to produce antioxidants is surpassed by the quantity of free radicals, harm may result because the body cannot cope.
As an example, let’s consider solar exposure. How can free radicals enter your body from sunlight? Your body may get overexposed to UV light from the sun, which can cause these unstable molecules and oxidative stress, also known as photoaging. One more reason why wearing sunscreen every day is vitally important.
Oxidative stress in the epidermis, the outermost layer of skin, can result in:
• A rise in trans-epidermal water loss, which causes the skin to become less hydrated.
• Uneven distribution of melanin results in an uneven skin tone.
• A slowdown in cell turnover leading to boredom.
• The epidermis’ thinning.
Oxidative stress in the dermis, the skin’s lowest layer, can result in:
• The production of proteoglycans, elastin, and collagen slows down, decreasing the structure and strength of our skin.
• A reduction in elasticity and firmness.
What then is the appearance of free radical damage? Overall, the skin gets rougher, thinner, and less radiant as a result of this oxidative stress. Furthermore, new wrinkles may appear.
4.How can I lessen the oxidation of my skin?
Yes, everyone has heard of an antioxidant. But what does it do, do you know? Antioxidants, as their name implies, aid in preventing oxidative stress.
Since antioxidants are molecules that enjoy sharing, they can give a free radical an electron and still maintain their stability. By neutralizing, postponing, or assisting in the prevention of additional harm, this serves to stabilize the free radical.
Even while our bodies naturally manufacture antioxidants, as we age, our bodies’ defense mechanisms against the damaging effects of pollution, sun exposure, and other factors that cause skin aging—like cigarette smoke—become less effective.
5.Which antioxidants are most beneficial for skin?
As numerous factors can lead to the production of free radicals, no one antioxidant works like a magic bullet, eliminating every single free radical it encounters. To provide maximal coverage against all aggressors, the greatest defense is actually a multi-pronged offensive that includes a variety of topical antioxidants. Several highly effective (and extensively studied) antioxidants include:
Vitamin C: Considered the mother of antioxidants, vitamin C is highly valued for its ability to effectively combat free radicals and enhance the body’s production of collagen. The sole drawback is that product formulations including L-ascorbic Acid, the pure and active form of vitamin C, are known to be unstable. For this reason, even while selecting a vitamin C serum formulated with a vitamin.
Vitamin A: Mostly accessible as over-the-counter Retinol, vitamin A is well-known for promoting collagen formation and decreasing acne. Nonetheless, one of its lesser-known superpowers is its antioxidant capacity.
lactic acid: Although lactic acid is well known as a mild AHA, it has also been shown to be a very useful antioxidant recently. This is likely due to the fact that lactic acid functions in the lipid layer of the skin, just like vitamin E. One thing to keep in mind, though: if you smooth your lactic acid item over (or beneath) a vitamin C serum, the vitamin C will be neutralized. But when the two components are combined to create a single product, the cosmetic chemist responsible for the mixture will have made sure they get along well.
Niacinamide: A variety of skincare products targeting these skin concerns contain niacinamide, also known as vitamin B3, which brightens the complexion, reduces redness, and treats sensitivity—all while stopping free radicals in their tracks.
Ferulic acid: Ferulic acid, on the other hand, is like the ultimate antioxidant wingman. Yes, it is an antioxidant on its own, but when combined with other antioxidants, it amplifies their response, making them even more effective.

Summary
In conclusion, successful skincare requires an understanding of the causes of free radicals and their detrimental consequences on the skin. These unstable chemicals are produced by the environment by sunlight, pollution, and lifestyle decisions. This results in oxidative stress and outward indications of aging. It’s imperative to include antioxidants in your skincare regimen to combat this.
Important antioxidants, such as ferulic acid, lactic acid, niacinamide (vitamin B3), vitamin C, and vitamin A (retinol), are essential for scavenging free radicals, encouraging the synthesis of collagen, and improving the general health of the skin. Although antioxidants are naturally produced by our bodies, their effectiveness can be diminished by age and exposure to environmental stresses. Consequently, selecting skincare products that include powerful antioxidants can offer a multifaceted fight against different aggressors making sure your skin remains youthful, bright, and robust. Recall that a comprehensive approach to skincare includes both topical treatments and preventative measures against environmental stresses in addition to a healthy lifestyle.
