Undecylenoyl phenylalanine, also known as Sepiwhite MSH is a skincare ingredient used in cosmetic products, particularly those that aim to brighten and help even out skin tone. It is a derivative of the amino acid phenylalanine and undecylenic acid. It works by inhibiting the production of melanin in the skin to reduce hyperpigmentation and the appearance of dark spots. Unlike many other skin lightening agents, undecylenoyl phenylalanine is considered to be gentle and safe for daily use. It can be found in various types of skincare products such as serums, moisturizers, and toners.

Tranexamic acid is used in the skincare industry for its skin brightening and anti-inflammatory properties. Here are some of its key functions and applications:

1. Skin brightening: Tranexamic acid helps to inhibit the production of melanin, which is the pigment that gives coloration to the skin. By reducing the amount of melanin produced, it can help to minimize the appearance of dark spots, hyperpigmentation, and uneven skin tone.

2. Anti-inflammatory: Tranexamic acid has anti-inflammatory properties and can help to reduce redness and irritation caused by inflammation, making it ideal for those looking to calm and soothe sensitive skin.

3. Acne: Tranexamic acid can also be used to help treat acne, as it helps to reduce inflammation and redness caused by breakouts.

4. Safe for use: Tranexamic acid is usually well-tolerated by most skin types when used in low concentrations. However, it is always advised to patch-test new products containing Tranexamic acid before use.

5. Multiple applications: The ingredient can be incorporated in a variety of skincare formulations including serums, toners, and creams.

Tranexamic acid can be a beneficial ingredient in skincare products for those looking to brighten their complexion, reduce the appearance of dark spots, and soothe irritated skin.
