Read on for our Skin Laundry guide to Tranexamic Acid. 

What is Tranexamic Acid and how does it work?  

Tranexamic Acid is an ingredient derived from the amino acid lysine that prevents melasma by inhibiting the development of skin hyperpigmentation and reducing tyrosinase activity (the enzyme that catalyzes the production of melanin).  

At the same time, it blocks the transfer of pigment from melanocytes (pigment-producing cells) to keratinocytes (the keratin-synthesizing cells found in the outermost layer of skin – the epidermis). Tranexamic Acid also decreases the skin’s sensitivity to UV.  

1. Tranexamic Acid helps prevent the formation of dark spots while actively improving existing discoloration.     
2. Tranexamic Acid helps fade the look of post-breakout marks of any color for all skin tones.  
3. Tranexamic Acid helps visibly reduce redness and may minimize the appearance of rosacea.   
4. Tranexamic Acid is a well-tolerated ingredient that is non-irritating and safe for all skin types.  
5. Tranexamic Acid has comparative benefits to other dark spot-diminishing creams (such as Hydroquinone) but is less irritating and safe for all skin tones. 

What is Hyperpigmentation?  

Hyperpigmentation is a term that describes a variety of skin conditions that produce dark patches. This is the result of your body producing an excess of melanin, the natural pigment that gives your skin its color.  

A number of factors can trigger an increase in melanin production, but the primary causes are sun exposure, hormonal influences, age and skin injuries, or inflammation.  

The three main types of hyperpigmentation are age spots, melasma, and post-inflammatory trauma. Post-inflammatory trauma can result from an injury, sun exposure, or a skin condition, such as acne.  

What is Melasma?  

Melasma is a common skin condition in which light to dark brown or greyish pigmentation develops on the face. Although it can affect all skin types and tones, it is more common in women, especially those with darker skin tones. Melasma usually becomes more noticeable in the summer and improves during the winter months.   

According to the American Academy of Dermatology, common melasma triggers include:  

1. Sun exposure: Ultraviolet (UV) light from the sun stimulates the melanocytes. In fact, just a small amount of sun exposure can make melasma return after fading. Sun exposure is why melasma is often worse in the summer. It also is the main reason why many people with melasma get it again and again.    
2. A change in hormones: Pregnant women often get melasma. When melasma appears in pregnant women, it is called chloasma, or the mask of pregnancy. Birth control pills and hormone replacement medicine also can trigger melasma.  
3. Skin care products: If a product irritates your skin, melasma can worsen.  

What is Rosacea? 

Rosacea is a common skin condition that causes redness and visible blood vessels on the cheeks, nose, chin and forehead. Commonly mistaken for acne or eczema, rosacea affects all skin tones, although it is most common in women aged forty to sixty with fairer skin tones.  

The cause of rosacea is not yet fully understood but it is thought to be a result of a combination of hereditary and environmental factors. While there is no cure for rosacea, there are skincare products and treatments that can alleviate, manage and even reverse the symptoms.
