Tranexamic acid, a new active ingredient to diminish pigmentation spots.
The tranexamic acid is a synthetic analogue of lysine. In the medical sector, taken orally or by injection, tranexamic acid has been used for about fifty years for its anti-haemorrhagic virtues. This molecule is even on the list of essential medicines of the World Health Organisation (WHO).
In cosmetics, tranexamic acid has only been incorporated into certain treatments for about a decade. Studies have demonstrated its ability to control pigmentation by inhibiting the release of inflammatory mediators involved in triggering melanogenesis. Thus, it is effective in combating the three types of hyperpigmentation: the melasma caused by hormonal imbalances, the lentigo due to excessive and repeated sun exposure, and the post-inflammatory hyperpigmentation which results from an overproduction of melanin following inflammation (injuries, burns, blemishes, acne flare-ups).
What are the adverse effects of tranexamic acid in cosmetics?
Firstly, for it to be effective on pigmented spots, the concentration of tranexamic acid must be within 2 and 5% in a skincare product. Increasing its concentration does not enhance its effects but poses a risk of irritation.
The side effects of tranexamic acid in topical application were reported in a study conducted in 2014 that focused on the attenuation of melasma with this molecule. The study indicates that the most common side effects are skin dryness, irritations and sometimes increased peeling. To avoid this type of skin discomfort, it is recommended to apply a moisturising cream following a tranexamic acid treatment.
If the skin tolerates this compound well from the outset, a tranexamic acid skincare product can be used according to a frequency of twice a day,morning and evening (it is not photosensitising ). On sensitive skin, its use will initially be limited to once a day, allowing the epidermis time to adjust to this new molecule.
It is important to clarify that if slight redness appears initially, it does not necessarily require the complete cessation of the use of a tranexamic acid skincare product.
However, in the event of excessive irritation or discomfort, immediately cease the use of the tranexamic acid skincare product.
The anti-spot and firmness-lacking serum by Typology.
The hyperpigmentation and firmness serum contains 5% tranexamic acid. This treatment reduces and prevents the appearance of pigmentation spots, particularly melasma, 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 supporting and firming the skin: elastin, collagen and fibrillin.
After applying this treatment, morning and evening, to counteract the slightly drying effect of tranexamic acid, you can use a face cream such as our nourishing face cream with hyaluronic acid and shea butter.
