What Are the Benefits of Vitamin C, Kojic Acid, and Hydroquinone?

Uneven skin pigmentation, usually in the form of sun spots and age spot, is a beauty problem for many people. While there are a lot of products available to treat it, making a choice can prove to be challenging. That is why it is best to focus on the active ingredients and find out what exact benefits they can bring to you. Let’s take a closer look at vitamin C, kojic acid and hydroquinone – the major ingredients used in skin care products for achieving even skin tone.

Vitamin C Works in More Ways than One

This compound is one of the most powerful antioxidants and brings multiple benefits. It helps to treat UV photodamage that is skin pigmentation. In this respect, it practically works as a bleaching agent. At the same time, it can provide protection from the UV rays of the sun and the damage which they cause including not only sun spots, but also fine lines and wrinkles. Its effect is even more potent when it is combined with vitamin E, another powerful antioxidant.

Vitamin C helps you fight aging even more defiantly by stimulating the production of collagen in the skin. Collagen makes the skin firmer and plumper and the result is a more youthful look. Because of its collagen boosting property, this vitamin is also present in creams for reducing acne scars, birth marks and other imperfections Another one of its major benefits is that it helps to reduce sensitivity. That is why it is highly recommended for people with dry and sensitive skin.

Kojic Acid

This is a natural chemical compound synthesized from organic substances. Its main effect on humans when applied topically is reduction of pigmentation such as freckles, sun spots and age spots. It works by reducing the production of melanin, meaning it counters the care cause of the problem. Since kojic acid is very potent it is used in small concentration in creams and similar products designed to treat uneven pigmentation. It can produce good results without causing side effects when used correctly.


This chemical compound works in a similar way to kojic acid. It inhibits the production of tyrosinase, which plays a role in the formation of melanin. This is how it can help to treat uneven pigmentation. When you apply a hydroquinone cream on the affected areas of the skin, it literally acts as a bleaching agent and make them lighter. This is how you can get even skin tone over time.

Just keep in mind that the products based on this ingredient, with the most common ones being 4% hydroquinone creams, should not be used over the long term. It is recommended that they are applied in cycles with each cycle lasting as many as 4 months. During your four-month break, you can use another type of product formulated to fight pigmentation like a cream with kojic acid, for example.

Overall, all three ingredients, vitamin C, hydroquinone and kojic acid, work effectively and safely for getting rid of uneven pigmentation when used correctly. It is always best to confirm that you are dealing with this problem and not with a mole or another growth by getting a check by a dermatologist first.

The body has its own natural mechanisms of healing wounds. They always work, but often have side effects in the form of scars. Since scars are natural, they are quite challenging to remove.

How Does Microneedling Work?

If you are not well-familiar with medical skin treatments, you may have not heard of microneedling. However, this therapy has been used by dermatologists for decades. Find out what it is, how it works, what benefits you can expect and what the level of safety is.

What It Does

This therapy involves poking small holes on the skin with the use of a specially designed needle device. It is usually a roller covered with tiny shallow needles, but it could also be a pen with needles at the top. The holes are practically microscopic injury. That is why the body’s natural reaction is to heal them by producing more collagen. This is similar to what bodybuilders do to stimulate the production of lean mass.

The Procedure

After cleaning your face, the dermatologist will apply anesthetic cream to the skin area which will be treated. It is worth noting that microneedling is designed not only for the face, but for all parts of the body. The next step involves the application of lubricant, which is usually water-based for maximum comfort. Then the dermatologist rolls the microneedling device over the skin of the patient.
One session typically takes less than half an hour. Just like with most minimally invasive treatments, several sessions are typically necessary. After the treatment, the patient’s skin is red, usually resembling the effects of sunburn. However, the redness goes away fairly quickly. The results are observed in the following weeks and months as collagen production isn’t a fast process.

What Can It Help With?

Traditionally, microneedling has been used as a treatment against scars and acne scars, in particular. However, in recent years, it is becoming highly popular as an anti-aging therapy. With the stimulation of collagen production, the depth of fine lines and wrinkles can be reduced considerably. The treatment is often used for targeting the fine lines and wrinkles around the mouth and on the upper lip. It also helps to make the face plumper and this naturally gives the patient a natural youthful look. One of the less common applications of the therapy is for treating stretch marks on various parts of the body from the abdomen and the chest to the legs.

Is It Painful?

Most patients experience mild to moderate discomfort during the microneedling procedure. The therapy is also claimed to be less painful compared to laser resurfacing. However, since every person has different pain tolerance, it is best to talk to your dermatologist first, if you have any concerns.

Is It Safe?

This anti-aging and scar treatment is generally safe for people who do not have skin conditions and severe skin allergies when it is performed by a qualified professional. Even though there are microneedling devices designed for home use, home treatments are associated with a higher risk of injury and infection of the skin. There is also the risk of an allergic reaction if the wrong creams and serums are applied before and after the procedure.

The Verdict

Overall, microneedling brings positive anti-aging and scar removal results while having a high level of safety. If you can tolerate mild pain, you may consider using
