There are weeks when your skin is just fine. And there are others when a breakout appears right before an event, everything irritates it, and nothing works as it should. It is not bad luck or neglect.

It has to do with your hormones.

And if you live with a partner, this also has to do with your relationship.

The hormonal cycle isn't just a "women's thing"

Although the menstrual cycle is the best-known example, men also have hormonal fluctuations. But the ones that most impact the skin are those of the female cycle, so we start there, so that both of you understand it.

The four phases and what they do to the skin

The menstrual cycle averages 28 days and is divided into four phases. Each has a different hormonal profile that is reflected directly in the skin.

Menstrual phase (days 1-5): sensitive skin without defense

Estrogen and progesterone levels are at their lowest point. The skin usually feels more sensitive, dull, and prone to irritation. It is common to experience dryness, pallor, and increased reactivity to products that are normally well tolerated.

The pain and fatigue typical of this period also raise cortisol, which can worsen any pre-existing inflammatory condition such as acne or dermatitis.

What the partner can do: if your partner is in this phase, it is not the best time to try a new product or to make a plan that involves wearing makeup for hours. A calm environment, without pressure, is what the skin and the entire body need.

Follicular phase (days 6-13): the best week for the skin

Estrogen begins to rise and, with it, comes a stage of renewal. The skin may look more luminous, firm, and even, while some people tolerate active ingredients like retinol or exfoliants better.

And just as the skin seems to recover its rhythm, it can also be a good time to recover yours as a couple.

What you can do as a couple: take advantage of this stage to resume that plan you have been postponing, organize a special dinner, or have that important conversation that requires the best disposition from both of you.

Ovulatory phase (days 14-16): maximum glow, but with nuances

Estrogen reaches its peak, and the skin usually looks more luminous, hydrated, and with better circulation. At the same time, the increase in progesterone can raise sebum production, especially in oily or combination skin. So, in some people, small breakouts may appear.

What the partner can do: it is a good time for activities that involve more social or physical contact, such as an outing with friends, a livelier plan, or simply enjoying the fact that energy and mood are at their highest point.

Luteal phase (days 17-28): the most complex week for skin and mood

This is where more visible changes usually appear. Progesterone increases and estrogen decreases, which can translate into more oil, more visible pores, breakouts—especially on the chin and jawline—and some fluid retention.

Mood can also change: more irritability, fatigue, or emotional sensitivity, and in some people, symptoms of premenstrual syndrome (PMS).

What the partner can do: understand that if there is more irritability or emotional sensitivity during these days, it is not "exaggeration," it is biochemistry. Not taking it personally is the first step. The second is to ask what is needed, instead of assuming.

What men should also know about their own hormones

Men do not have a monthly cycle, but they do have hormonal fluctuations that affect skin and mood:

Testosterone and skin: high levels of testosterone stimulate the sebaceous glands, which is why male skin tends to be oilier and more prone to acne than female skin. In times of high stress, testosterone can drop and cortisol can rise, which weakens the skin barrier and can cause unusual dryness or sensitivity.

Cortisol as a common enemy: both men and women produce cortisol in response to stress. And cortisol is, of all hormonal factors, the one that causes the most damage to the skin: it breaks down collagen, weakens the skin barrier, activates inflammation, and triggers acne. A relationship with a lot of unresolved conflict, or a period of high work stress, will be reflected in the skin of both.

How to use this knowledge as a couple

It is not about keeping a hormonal calendar as if it were a control system. It is about something much simpler: being curious, understanding each other, and accompanying each other better.

Some ways to put it into practice:

Talk without dramatizing: saying “I’m in the days before my period and my skin is more sensitive… and I am too” is useful information, not a complaint.

Adapt skincare to each stage: during the luteal phase, you can prioritize hydration and soothing products, such as niacinamide, centella asiatica, or aloe, and avoid overly aggressive routines. In the follicular phase, if you want to try new active ingredients, it may be a good time to do so.

Skin communicates too

What happens inside the body, from hormones to stress and emotions, often ends up being reflected on the skin. Understanding these changes together can reduce misunderstandings and turn them into information to support each other, not into a cause for conflict.

Because knowing each other's body is also a way of taking care of it.
