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.
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.
