Can niacinamide stock solution be used during the day? Does niacinamide stock solution need to be used away from light?

Niacinamide is a powerful ingredient in beauty products. Many girls will buy niacinamide stock solution for daily skin care. Some skin care products need to be used away from light, so can niacinamide stock solution be used during the day?

Niacinamide is not photosensitivity and has good antioxidant effects. It will not change its properties or lose its effectiveness due to ultraviolet radiation, so it can be used during the day.

Whitening is a topic that almost all girls are studying. How to whiten safely and effectively is a question that every girl is thinking about. For this purpose, a variety of skin care plans have been developed. Use one whitening essence during the day and another at night. In fact, it is not that troublesome. Niacinamide can be used during the day and at night.

Nicotinamide is a derivative of vitamin B3 that can regulate the movement rate of melanosomes. Melanosomes are pigment particles in pigment cells. As the concentration of nicotinamide increases, the density of melanosomes decreases. Nicotinamide inhibits the production of melanin and can also dilute the melanin that has already been produced.

Nicotinamide participates in metabolism within cells and regulates the balance of NADH and NADPH, thereby exerting a powerful antioxidant effect, preventing the occurrence of glycation reactions, and avoiding skin aging and dull complexion.

Niacinamide is not photosensitivity and can be used during the day. Niacinamide also has antioxidant effects, which can prevent the properties of niacinamide from changing and losing its effect due to ultraviolet radiation.

Niacinamide must be used in conjunction with sunscreen when used during the day. If you do not use sunscreen, it will only be a process to avoid getting darker and will not maximize the whitening effect. Whitening and sunscreen work synergistically to achieve the effect of 1+1>2.

No need to avoid light. Niacinamide is very effective in fading spots and acne marks, so using it in the morning and evening can achieve better whitening effects. Niacinamide does not cause photosensitivity, so it can also be used during the day.

There are two orders for using niacinamide stock solution.

1. Direct use

Direct use means applying niacinamide stock solution directly to the skin. Generally, after cleaning the face with facial cleanser, moistening the skin with toner and performing secondary cleansing, you can use niacinamide stock solution and apply it directly to the required areas of the face skin. The order of use is facial cleanser → toner → niacinamide stock solution → lotion/cream. Be sure to pay attention to the concentration of niacinamide and test whether your skin will reject niacinamide before use.

2. Mixed Use

Mixed use means mixing niacinamide stock solution with other skin care products such as creams or lotions. In this way, the irritation to the skin will be slightly weaker, and the order of use is the normal order of use of other skin care products such as creams and lotions.

No matter how to use it, the order of using niacinamide stock solution is basically after toner, or it can be used in the order of skin care products mixed with it, which is quite convenient.

1. Build tolerance

Niacinamide is a very useful skin care ingredient, but it is not recommended to use it directly, because some people's skin may not be able to accept the stimulation of niacinamide all at once, so you need to build tolerance to it and ensure that your skin will not be allergic and there is no strong tingling and discomfort before you can continue to use it. You can apply it on your wrists or ears in small amounts multiple times to build up tolerance little by little.

2. Take good sun protection

When using niacinamide, remember to use sunscreen. Niacinamide can be used during the day, but it is best used at night. If you decide to use it in the morning and evening to enhance the effect, that is also fine. But remember to use sunscreen to avoid affecting the effect of niacinamide.

3. Nicotinamide cannot be mixed with acids

If you mix them together, it is likely to cause damage and irritation to the skin. Because niacinamide itself has a little irritation, when mixed with acidic substances, niacinamide will release a large amount of niacin. If you need to use acid for your daily skin care, you can use niacinamide during the day and acid at night.

4. Suitable for skin type

Niacinamide does not have fixed skin type requirements. Whether it is dry skin, neutral skin or oily skin, it can be used safely. Just remember to build tolerance before use to ensure that the skin can accept it, and then slowly stabilize the amount and frequency of use. If you feel discomfort in the early stage of use, you can mostly use it after tolerance is built up.

PS: However, if you are allergic to a specific ingredient, it is recommended that you do not use it. Friends with sensitive skin should also use it with caution to avoid skin allergies.
