To diminish the appearance of pigmentation spots that affect skin tone uniformity, various active ingredients exist in skincare such as the arbutin acid or the tranexamic acid. We have focused on the latter, as well as its timing and frequency of application.
When and how often should tranexamic acid be used?

An overview of Tranexamic Acid.
Thetranexamic acid is a synthetic derivative of the amino acid lysine, a component naturally present in the skin.
In the cosmetic universe, tranexamic acid is a recent active ingredient that is the subject of an increasing number of scientific publications, particularly on its lightening virtues.
Unlike other acids found in skincare (glycolic acid, lactic acid, salicylic acid, etc...), tranexamic acid does not exfoliate the epidermis but disrupts the excessive production of melanin, which causes hyperpigmentation. Indeed, it inhibits UV-induced melanin synthesis by blocking the interaction between keratinocytes (skin cells) and melanocytes (melanin-producing cells). It specifically targets melasma of the epidermal type (or pregnancy mask), solar spots, the post-acne hyperpigmented marks (post-inflammatory hyperpigmentation), as well as pigmented dark circles.
When should you apply a treatment with tranexamic acid?
Non-photosensitising, a tranexamic acid skincare product can be used at a frequency of twice a day, morning and evening. For sensitive or irritated skin, its use should initially be limited to once a day. If you notice that the skin tolerates the product well, you can then move to two applications per day. In case of irritations or uncomfortable sensations, immediately stop using the tranexamic acid skincare product.
Even though it is a mild acid well tolerated by all skin types, we recommend performing a skin tolerance test to avoid the risk of allergies. To do this, apply a small amount of tranexamic acid product to the inside of your wrist or a small part of your face and wait 48 hours. If no reaction occurs, the treatment can be applied to the face.
Note : The effects of tranexamic acid are progressive. A reduction in the appearance of pigmented spots is generally visible after 8 to 12 weeks of application.
Discover our serum with tranexamic acid and tetrapeptide-2.
The hyperpigmentation and firmness serum from Typology contains 5% tranexamic acid. This treatment reduces and prevents the appearance of pigment spots and promotes skin firming. The complexion is even, the skin is smoother and firmer. It also contains acetyl tetrapeptide-2, a peptide composed of four amino acids that stimulate the synthesis of key molecules involved in skin support and firmness: elastin, collagen and fibrillin.
Regarding its use, we recommend applying it twice a day, morning and evening. This serum is suitable for all skin types and is particularly beneficial for skin prone to brown spots and lacking firmness.
