Bai Bai Chubby, a Chinese idiom, means to describe fair skin and plump body. From "The Outer History of Confucianism. The sixth round": "It is useless to ask God everywhere for Zhao to make wishes. On the seventh day, the chubby child ran away. ”
However, everyone is willing to just be "white" and not "fat".
Nowadays, there are many skincare products that claim to be whitening, such as SKII small bulbs, Olay small white bottles, Paula's choice serum, and The Ordinary's 10% niacinamide serum...... And these products all contain an ingredient---niacinamide.
What is Niacinamide?
烟酰胺（Niacinamide, also called nicotinamide），学名吡啶-3-甲酰胺，又名尼克酰胺、烟碱酰胺，简称 VB3 或 NSA。
It is a water-soluble substance that is solution-stable and photostable and is a form of vitamin B3. Niacinamide helps build proteins in the skin and locks in moisture (1), helps the skin form a ceramide (lipid) barrier (1), keeps the skin smooth and moisturized (1), improves the skin's barrier function, prevents the skin from losing moisture, and protects it from pollutants and irritation, making it particularly gentle on the skin, regulates the amount of oil produced by the sebaceous glands (2), protects skin cells from UV damage (3), reduces pigmentation (4), reduces fine lines and wrinkles (5), Nicotinamide enhances cellular energy and regulates poly-ADP-ribose polymerase 1, which plays an important role in DNA repair and the expression of inflammatory cytokines, accelerating cell metabolism and accelerating the shedding of melanocytes in addition to the traditional whitening effect. Nicotinamide has shown promise for the treatment of various skin conditions, including autoimmune blistering diseases, acne, rosacea, skin aging, and atopic dermatitis (6).
Niacinamide has been shown to be a potent skin-brightening compound that significantly reduces hyperpigmentation and increases skin brightness after 4 weeks of use by inhibiting the transfer of melanosomes from melanocytes to keratinocytes (7). A study (8) conducted clinical trials in Japan and the United States to evaluate the effects of topical use of nicotinamide 2% in different ethnic groups. The results showed that topical nicotinamide 2% may be effective in reducing sebum excretion rate (SER) and reducing sebum levels (CSL) in Caucasians.

Niacinamide intolerance problems (13):
A small percentage of people who initially use products containing niacinamide develop allergies. Symptoms of allergies are envelope skin redness, itching, stinging, etc. These symptoms are more likely to occur in cold, dry climates.
The cause of allergies lies in the niacin in niacinamide and depends on the individual's genes and skin sensitivities. Nicotinamide has the best stability in a solution with a pH value of 6. In a solution with a pH above or below 6, it hydrolyzes to form niacin, which can lead to skin irritation. Therefore, the formula containing nicotinamide generally controls the pH between 5~7 to reduce the formation of niacin.
For those whose symptoms are not too severe, you can reduce the dosage and get used to it slowly, and if you are lucky, your skin will build up tolerance to niacin after repeated use.
Therefore, friends who want to whiten can try products containing niacinamide, we just need to be "white", not "fat"!
