Unique effects
Sepiwhite MSH Powder inhibits the synthesis of melanin by blocking the binding of α-MSH (melanocyte stimulating hormone) and melanin production factors, thereby preventing the formation of pigmentation. It can effectively interfere with α-MSH and reduce the production of melanin at a concentration of 0.001%. The use of higher concentrations (such as 1%) can fully inhibit the production of melanin at multiple levels, achieving a more significant and lasting skin lightening effect.

Advantages of skin lightening and whitening:
- Highly effective whitening: Blocking the melanin production process significantly reduces uneven skin tone and the appearance of spots.
- Scientific verification: Studies have shown that Sepiwhite can effectively inhibit melanin production at low concentrations, and the effect is more significant when using a 1% concentration.
- Comprehensive anti-melanin: It reduces melanin production and effectively prevents the formation of new spots, helping maintain a long-lasting white skin color.
- Suitable for a variety of skin types: Whether it is post-sun skin color problems, spots or other melanin deposition problems, Sepiwhite Powder can provide an effective solution.

other benefits of Sepiwhite MSH Powder
1. Antioxidant:
It has antioxidant ability and can remove free radicals. We know that the skin will produce a large number of free radicals under the influence of environmental factors such as ultraviolet rays and pollution. These free radicals will attack biological molecules such as lipids, proteins and DNA in skin cells, thereby causing skin aging, dullness and other problems. And acylamine can provide hydrogen atoms to combine with free radicals, making the free radicals inactive, thereby reducing their damage to skin cells.
At the same time, it can remove free radicals that destroy collagen and elastic fibers, effectively delay skin aging, maintain the elasticity and firmness of the skin, and make the skin appear healthy and shiny.
2. Regulate skin condition:
Sepiwhite MSH Powder can regulate the oil secretion of the skin. For oily skin, it can reduce excessive oil secretion and keep the skin fresh; for dry skin, it helps to improve the water and oil balance of the skin and prevent the skin from being too dry.
It can also promote the microcirculation of the skin, increase the nutrient supply of skin cells and the discharge of metabolic waste. This is conducive to maintaining the normal physiological function of the skin and making the skin healthier. For example, good microcirculation can accelerate the absorption of nutrients in skin care products by skin cells and enhance the skin care effect.
3. Synergistic effect
Ingredients similar to acylbenzamide, such as niacinamide, have significant synergistic whitening effects. Niacinamide whitens by inhibiting the transport of melanosomes from melanocytes to keratinocytes. Acylbenzamide inhibits the production of melanin, and the combination of the two can further enhance the whitening effect. Studies have shown that the combination of 1% undecylenoylphenylalanine and 5% niacinamide is more effective than niacinamide alone, and can more effectively reduce melanin production and improve skin tone uniformity.
In addition, the Sepiwhite MSH Powder ingredient is easy to incorporate into various formulas, has excellent compatibility and stability, and its lipid amino acid structure gives the ingredient significant skin bioaffinity. This allows it to be well-compatible with other whitening ingredients to further optimize the whitening effect. Due to its unique mechanism of action, the combination of undecylenoylphenylalanine with whitening ingredients such as niacinamide, 4-butylresorcinol, and phenylethylresorcinol has an excellent synergistic effect, which can not only independently complete the whitening and spot-lightening task, but also comprehensively enhance the whitening effect of the entire combination.

For example, in 2024, a company applied for a patent called "Adenosine-Undecylenoyl Phenylalanine Synergistic Whitening Composition and Preparation Method thereof". The core active ingredients of this whitening composition include adenosine, dipotassium glycyrrhizinate, undecylenoyl phenylalanine, niacinamide and vitamin C derivatives. Among them, adenosine inhibits the production of melanin from the source by inhibiting the activity of melanocytes. It works together with other whitening ingredients such as undecylenoyl phenylalanine to achieve full-chain blocking of melanin production and deposition, significantly improving the whitening effect. In addition, the composition not only has obvious whitening effect, but also has excellent stability and safety, and is suitable for long-term use.
Sepiwhite MSH Powder is widely used in:
Skin whitening products
Sunscreen and after-sun repair products
Blemish-removing products
Skin brightening serums and creams

use suggestion of Sepiwhite MSH Powder
Undecenoyl phenylalanine is a key ingredient that is often added during the cooling phase of a formulation to ensure stability. It is soluble in propylene glycol and other solvents, but poorly soluble in water, so it is often used in emulsions or anhydrous systems.
Use rate: The recommended use rate is between 1-2%.
- pH stability range: Stable in formulations with a pH of 4.0 to 6.5.
- Solubility: Soluble in alcohols and glycols, poorly soluble in water.
- Reasons for use in formulations: Undecenoyl phenylalanine is used in formulations to address hyperpigmentation, dark spots, and uneven skin tone. It offers an alternative to more traditional skin lighteners such as hydroquinone, and is a milder and well-tolerated option for sensitive skin.
- Consequences of loss of stability in formulations: Sepiwhite MSH Powder may degrade if exposed to temperatures above recommended levels or incompatible pH environments, resulting in reduced effectiveness in inhibiting melanin production. It may also lose stability in formulations containing high concentrations of acid or base.
