We all want to get rid of those “bothering” wrinkles. But first, let’s see what they are.


Según According to the Spanish Academy of Language (known in Spanish as RAE), a wrinkle is a line or crease in the skin due to age. From a dermatological point of view, they are seen as skin folding due to the loss of flexibility.

We all know that wrinkles are considered a sign of age. Also, the decrease of the adipose panicle of the skin (the most external layer isolating us from cold and heat, which acts as a pad and maintains nutritional reserves) also increases the wrinkling process.

Nightbra is the ONLY antiwrinkle bra that removes cleavage wrinkles and prevents them from appearing


Wrinkles appear due to different factors: our genetics, the impact of the environment (the wind, the sun and UVA rays), the loss of weight, the food we eat, smoking, illnesses, sleep deprivation, gravity… and, of course, the ageing process and the repetition of certain movements and positions.


If we focus on cleavage wrinkles, the first thing we need to know is that the skin covering our breasts is the same as that of the cleavage; the difference is that, under this skin, mammary glands are located in the area that goes from the parasternal to the mid-axillary line (horizontal line) and from the 2nd to the 6th rib (vertical line). The chest wall is the base holding the cleavage area and the breasts. Even though the skin is the same, it does not behave the same way in the two mentioned areas, since the cleavage is more exposed to external environmental factors and the repetition of certain gestures along the years; the same thing applies to the skin covering the breast bone and the area between the two breasts.


It’s obvious that from birth to old age, the image of our breasts changes and so do our mammary glands. These changes start at the reproductive stage and they take place during the menstrual cycle (pre and post-ovulatory phases), when taking contraceptive pills, during breastfeeding and menopause; and they cause, among other things, changes in their volume. Interesting fact: the average weight of a breast ranges from 200 to 450 grams and they are considered large when weighing 450+ g. When a mother is breastfeeding, they usually weigh 600 to 800 g.

It is also interesting to know that between the ages of 20 and 30, 30% of the breast is fat; whereas it comes up to 40% at the age of 50 and around 60% when we turn 60. This happens because the mammary gland starts to disappear and it is replaced by fatty tissue.

As per the ageing process, we must highlight that the inframammary fold keeps on deepening and the area between breasts keeps diminishing; which means that the breast tends to descend and the cleavage, including the area between the breasts, starts to wrinkle.

Also, we need to know that breasts are made of glandular epithelium, connective tissue and fatty tissue. Of course, there are also veins, arteries, lymph ducts and lymph nodes.


When referring to breasts, lymph nodes are always mentioned, since 75% of the lymph flow takes place through the axillary lymph nodes (of which we have around 30 in each armpit). Also, breast cancer is usually disseminated though the lymphatic system.

Speaking of the armpit, it is also relevant to mention that the mammary gland generally extends towards the armpit and it can even reach it.

For these reasons, you shouldn’t sleep wearing bras with padded cups, since that would stop a proper lymph drainage. Also, the axillary areas must not be pressed for 24 hours, which would prevent the lymph system in this area from working correctly.

When sleeping we are not aware the positions we adopt. Due to this, breasts move, so using padded cups is completely pointless given that the breast never follows the tissue; that is to say, when sleeping on the side, the breast will be out of the padded cups.


Breasts are linked to the pectoral muscle through connective tissue and they slide on the underlying muscles: the upper quadrants are placed on the pectoralis major muscles, whereas the inferior quadrants are placed over the rectus abdominis muscle.

Therefore, breasts have no muscle or ligaments since, in order to keep them tight, we need to strengthen our chest muscles. Another reason not to sleep with padded bras: breasts fall. For this reason, we must strengthen our chest muscles.


We must use the right bra during the day, one that adapts to the outer part of the breasts, with comfortable straps so our shoulders do not suffer, and which has the best cups as per the size/weight of our breasts.

Try not to practise sports which would make the breast go up and down. We recommend you swimming and volleyball, as well as training the pectoralis muscles.

Also, try to adopt good postures during the day, keeping your back straight.

During the night, use a system that totally adapts to the chest wall but releases the breasts and the glands, does not press the armpit with padded cups or any other elements and strengthens the chest muscles.


>During our sleep we are not aware of the postures we adopt. As a result, our breasts move one over the other; the heavier the weight, the wider the movement. Due to this fact, we must use any system that totally adapts to our chest walls, freeing our breasts with their glands and our armpits and stopping the wrinkling of our cleavages. Nightbra was created by Dr. Elisa Fernández to solve this problem. Nightbra is the ONLY bra created with medical knowledge and to have been clinically tested since 1996.
