Tranexamic Acid for Skin: The Complete Guide

Tranexamic acid has taken the beauty world by storm with its remarkable benefits and impressive results. If you have dark spots, or hyperpigmentation, or just want a brighter complexion, this ingredient could be the one for you.

Join us as we dive deep into the science behind tranexamic acid and uncover its ability to transform your skin.

What is Tranexamic Acid?

Tranexamic acid (TXA) is a synthetic version of lysine, an amino acid that has been used to treat bleeding disorders and blood clots for many years. However, in recent years, its use in skincare has gained popularity because of its multiple benefits on the skin.

In simple terms, TXA works by inhibiting plasmin - an enzyme responsible for breaking down blood clots. By doing so, it helps reduce excessive bleeding or bruising from injuries or surgeries. Similarly, when applied topically on the skin, TXA also helps reduce hyperpigmentation and promote overall skin health.

When our skin is injured or traumatized, the production of melanin increases during the healing process of the wound. This increase in melanin can cause post-inflammatory skin pigmentation (PIH), causing dark spots on the affected area. TXA inhibits tyrosinase, an enzyme involved in the production of melanin. Tyrosinase is responsible for the production of excess melanin, which helps to prevent the formation of dark spots.

Moreover, research has shown that TXA also has anti-inflammatory properties that help calm down irritated and inflamed skin. It does so by inhibiting inflammatory mediators like histamine and prostaglandins.

Another significant benefit of using TXA in skincare is its ability to improve collagen production. Collagen is essential for maintaining skin elasticity and firmness but decreases with age leading to wrinkles and sagging skin. Studies have found that topical application of TXA stimulates collagen synthesis and improves overall skin texture and firmness.

Benefits of using Tranexamic Acid for skin

1. Reduces hyperpigmentation: Hyperpigmentation happens when there's excess melanin in your skin, which can be caused by sun exposure, hormonal changes, or inflammation. Studies have shown that regular use of tranexamic acid can improve the appearance of hyperpigmentation.

2. Treats melasma: Melasma is a type of skin discoloration that appears as large spots on the face. It’s caused by hormonal changes during pregnancy or during birth control usage. Tranexamic Acid blocks the production of melanin, which is why it’s considered the best treatment for melasma. Its ability to penetrate deep into the layers of the skin makes it particularly beneficial for treating stubborn melasma.

3. Anti-inflammatory properties: One of the most common causes of acne, redness and irritation is inflammation. Tranexamic acid has anti-inflammatory properties that make it effective in reducing inflammation and calming down skin conditions. It can help soothe redness and irritation, making it suitable for those with sensitive skin.

4. Improves skin texture: Tranexamic acid stimulates the production of collagen in the skin. Collagen is a type of protein that helps keep your skin healthy and youthful. However, as you age, collagen production naturally decreases. Tranexamic Acid stimulates the production of collagen, which helps to improve your skin’s texture and reduce wrinkles and fine lines.

5. Lightens dark circles: Dark under-eye circles are a common concern for many people, often caused by genetics, lack of sleep, or aging. Tranexamic acid's ability to inhibit melanin production can also make it effective in lightening dark circles under the eyes. Regular use can help brighten the under-eye area and reduce the appearance of dark circles.

6. Minimizes acne scars: Acne scars are a common concern for those who have struggled with severe acne in the past. Tranexamic acid helps to heal acne scars by increasing collagen production and decreasing inflammation. It can also help fade dark spots left behind by acne, making the skin appear smoother and more even-toned.

Possible side effects and precautions

Possible side effects are not something you want to overlook, as they can have a huge impact on your skin’s health and appearance. Tranexamic acid is effective at treating many skin conditions, however, there are a few precautions to look out for.

1. Skin irritation: The most common side effect of using tranexamic acid is skin irritation. This can manifest as redness, itching, burning sensation or even peeling of the skin. It occurs when the concentration used is too high for your skin or when you have a sensitive skin type. To prevent this, always patch test on a tiny area of skin before applying to the entire face.

2. Dryness: Tranexamic acid can also cause dryness and flakiness in some individuals due to its exfoliating properties. The acid can pull dead skin cells away from the skin’s surface, leaving the skin exposed to moisture-depleting factors. If your skin gets dry from using tranexamic acid, use it less often or switch to a gentler formula.

3. Sensitivity to sunlight: Because tranexamic acid causes photosensitivity, skin becomes more sensitive to UV rays from the sun. Therefore, it is essential to wear sunscreen with SPF 30 daily while using this ingredient.

4. Allergic reactions: Although rare, some individuals may be allergic to tranexamic acid. If you experience hives, swelling, or difficulty breathing, discontinue use and seek medical attention immediately.

Always check with your dermatologist before adding tranexamic acid to your daily skincare routine. This is especially true if you have skin sensitivities or allergies. Pregnant and breastfeeding women should also consult their doctor before using products containing this ingredient.

Avoid other exfoliating ingredients such as AHAs or BHAs while using products containing tranexamic acid to prevent over-exfoliation and irritation. Also, do not use this ingredient on open wounds or irritated skin.
