Any woman can develop brown spots regardless of her genetics. UV radiation makes them more likely to appear.


Pigmentation through increased melanin synthesis is one of the skin’s defence mechanisms. Tanning is the skin’s way of dealing with ultraviolet radiation.

UV radiation causes melanocytes (cells located in the epidermis) to produce a brown pigment which is transferred to the epidermal surface by keratinocytes.

Different types of skin (phototypes) produce different amounts of melanin. They have a genetic basis.

This pigmentation can become disorganised: when too much melanin is produced in certain areas, it gets concentrated and the skin becomes locally darker.

This is known as “hyperpigmentation”:

  • Brown spots of varying size form in contrast with the lighter skin around them.
  • These spots are benign and painless but often unsightly.


Several causes can be behind the development of brown spots: 

  • Excessive sun exposure,
  • Age,
  • Hormonal changes (e.g; during pregnancy),
  • Genetic predispositions,
  • Skin trauma (scars).


Hyperpigmentation can manifest in different ways depending on the cause :


Freckles or ephelides, usually seen in blonds or redheads with light-coloured eyes and skin, are small brown spots which become darker and multiply when exposed to the sun. These charming but not always attractive spots have a genetic basis. They appear during childhood, become more conspicuous during puberty and often fade around age thirty.


Melasma, which is linked to hormonal changes and made worse by sun exposure, manifests in the shape of brown patches scattered symmetrically around the forehead, nose and cheeks. It often affects brown-haired people with olive skin. Melasma is particularly prevalent among pregnant women, giving rise to the names “mask of pregnancy” and “chloasma”, and usually disappears a few months after delivery. It can also appear as a result of oral contraceptive use or hormonal disorders.


Lentigines —small, brown, rounded or oval spots— can be related to age (age spots) or excessive sun exposure (solar lentigo). They appear when the epidermis is unable to cope with the deleterious effects of ultraviolet radiation. Fair-skinned people are more vulnerable to sun exposure and therefore at greater risk of lentigo.

Post inflammatory hyperpigmentations

Whenever a person sustains an injury (cuts, burns, etc.), gets an infection, suffers a cutaneous drug reaction or develops skin disorders such as eczemas or acne, the affected skin can become darker. This type of hyperpigmentation is particularly frequent on olive or dark skin, which contains more melanin.

All types of brown spots get worse if exposed to the sun without protection.

  • Protect your skin from ultraviolet radiation (clothes, hats, etc.) and use high-factor sunscreen. Reapply every two hours.
  • Apply SPF50+ sunscreen every morning and reapply every two hours when out in the sun. Remember to protect your chest area and the back of your hands, which are particularly susceptible to brown spots.
  • Use a regenerative and/or lightening care product at night.
  • Follow a healthy and balanced diet rich in antioxidants.


IPSYS Wh is an all-new vitamin-peptide programme which modulates the activity of cells involved in pigmentation and has a significant effect on melanocytes and keratinocytes.

Brown spots fade, the skin tones becomes more uniform and light, and skin quality improves from the start of the treatment.
