Also in the world of 'skincare' there is a lot of information circulating, but not all of it corresponds to reality. Dermatologist Marta Ribeiro Teixeira, from Clínica Espregueira, in Porto, reveals five myths that can even harm the health of our skin.
1- Oily skin should not be hydrated
Oily skin should also be hydrated. Simply using specific and suitable products, with lighter textures and preferably non-comedogenic and 'oil-free'. If we dry out oily skin too much, this will lead to compensatory sebaceous overproduction and, therefore, more oiliness.
2- Day cream is the same as night cream
The big differences between day and night creams are related to their functions, because our skin has different needs at each stage of the day. Therefore, creams vary in texture and the ingredients that make them up.
The functions of a day cream are, in addition to hydration, protecting our skin against external aggressors such as ultraviolet radiation, pollution and temperature changes. In this way, they present active ingredients with antioxidant characteristics that help our skin cells fight oxidative stress and can even offer sun protection. And, if your skin has specific problems, such as acne, oiliness or rosacea, the day cream may also contain specific ingredients that combat these problems throughout the day. Day creams have a lighter texture and absorb faster, which makes makeup application easier.
The main function of night creams is to regenerate the skin and minimize the effects of aggressions that the skin has suffered during the day. During sleep, the capacity for cell renewal and regeneration increases and it is the best time of day to use active ingredients that will repair our skin barrier, stimulate collagen production and deeply nourish the skin. Night creams typically have denser, more nourishing textures, are absorbed more slowly and provide longer-lasting hydration. For the reasons mentioned above and the fact that, at night, our skin is not exposed to the sun, they may contain active substances in their composition that will stimulate collagen production and delay skin aging, such as retinol, the acid glycolic, peptides, among others. Also, some specific problems such as blemishes, wrinkles, acne, rosacea, among others, can be treated more intensely at this time of day.
3- The skin gets used to the creams and they stop working
The skin does not get used to products, but the skin is simply always changing and its needs change over time, with age, with the level of stress, with the season, with the climate of the country we are in and, in the case of women, with the menstrual cycle phase and with the entry into menopause. In other words, a cream that is at one time suitable for our skin may, over time, no longer be. Furthermore, it is natural that during the first months of treatment with a certain cosmetic, its effects become more visible. Then we simply forget what our skin was like without using it. An example of this is the use of creams with anti-blemish substances. The skin simply requires products suited to what it needs at any given time.
4- Toothpaste is good for treating pimples
In addition to not making pimples disappear, it can also worsen their inflammation, which can ultimately leave blemishes and scars. One would think that the presence of antibacterial substances in toothpastes could have a positive effect on acne. But these products are not formulated to safely apply to the face, but to the teeth. Its use on the skin can damage the skin barrier and lead to the development of perioral dermatitis, inflammation similar to acne or rosacea near the mouth. The most important thing in case of acne is to consult a Dermatologist and have an adequate skincare routine, which will make pimples appear much less frequently and ideally disappear altogether. There are currently several safe cosmetic products tested for SOS effects on sale in pharmacies. For these reasons, I advise against using toothpaste to treat pimples.
5- Pulling out mole hair can cause it to degenerate into skin cancer
Plucking hair from chicks is not harmful and there is no evidence that it can result in skin cancer. In the worst case scenario, what can happen is inflammation in the hair follicle due to mechanical trauma resulting from pulling out the hair. In some cases, this trauma resulting from hair traction can be such that it irreversibly damages the area of hair growth, eliminating it immediately. Furthermore, the fact that a mole has hair is not a cause for concern. On the other hand, moles must be monitored and changes in size or color changes of a mole must be analyzed in consultation.
