How Your Body Changes During Puberty
By SELENACARE Redaktion · 10 September 2025
Puberty – what does it actually mean?
Puberty is a phase in which your body develops from child to adult. A lot happens at the same time – controlled by hormones that set your development in motion. Some changes are clearly visible, others take place more on the inside. What's important: there is no "normal" that applies to everyone. Every body has its own pace. And that is absolutely okay.
Outer changes: what visibly changes
You may notice it first in your body – because a lot is going on here.
Typical outer changes:
- Your breasts start to grow
- Your hips get wider
- You get discharge for the first time
- Your first period announces itself
- You get spots or oilier skin
- You sweat more – body odour gets stronger
- Body hair starts to grow under your arms or in the intimate area
Body odour during puberty in particular is nothing unusual – your sweat glands work more actively, and sometimes that simply smells different. Daily washing, fresh clothes and breathable fabrics help you feel comfortable. A mild, fragrance-free deodorant can offer additional support – look for natural ingredients.
Inner changes: hormones, feelings & thoughts
While a lot changes on the outside, a lot happens on the inside too. The hormones responsible for physical development also influence your emotional world, your thinking and your perception.
What can change on the inside:
- You experience mood swings – from over the moon to totally irritable
- You start to perceive yourself and others differently
- You develop a stronger need for retreat or independence
- You become curious about sexuality – about thoughts, feelings or relationships
All of this is part of puberty. Your emotions are not random – they are influenced by hormonal changes. If one day you simply don't want to get out of bed and the next you're bursting with energy, that's not a contradiction but a very typical sign of this phase.
Puberty and sexuality: you're allowed to be curious
With physical maturation, your sexuality develops too. Maybe you're interested in what your own body or relationships are all about. Maybe you notice that you're starting to fall in love – or not. Both are completely okay. You don't have to know or decide anything before you're ready. It's not about pleasing someone else, but about finding out what matters to you. Take the time you need.
Your first period – all a matter of the right support
The first period is a key moment for many. Maybe you're excited, maybe unsettled – or curious. However you feel: there are different ways to feel secure during your period. What matters is finding out what suits you.
Period underwear is especially practical if you like things uncomplicated.
Simply put it on, wear it, wash it – no waste, no worries. Ideal for school days or at home.

The SELENACARE Easy Comfort Period Set The SELENACARE Easy Comfort Period Set consists of two parts. The SELENACARE Easy Comfort Basic Panties are the core of our system and are equipped with the self-adhesive material in the crotch – a brilliant base for the SELENACARE Easy Comfort Inserts, the second part of the period set. Absorbent Easy Comfort Inserts with Wetbag The Easy Comfort Inserts are equipped with the specially developed self-adhesive material on one side and are ideally matched to the Basic Panties. This makes inserting them into the crotch area of the panties incredibly easy. Thanks to this self-adhesive property, the insert stays securely in place and does not slip, without relying on uncomfortable or annoying attachment methods. With various levels of absorbency, they are ready to accompany you in every phase of your period – from light to heavy, we've got you covered. Once the Easy Comfort Inserts are fully saturated, they can be easily removed from the Basic Panties and replaced with a new insert.

The Hipster period underwear is ideal for the light and medium days of your period. It provides a dry feeling and does not allow fluid to leak out. On your heavier days, we recommend using the underwear in combination with a menstrual cup or tampon. If you have periods or spotting, you can use either a period slip or a washable pad, depending on the intensity of the bleeding. No restrictions, always well protected There are really no limits to the use of period underwear. You can use them in your free time, at work or on holiday. In addition to period blood, it also absorbs sweat and other fluids and reliably seals them in. Because the material is absorbent, it also gives you a very safe feeling during sports. After use, you can wash the panties out with cold water, air dry them and reuse them. This makes them a convenient, sustainable and environmentally friendly alternative to tampons and disposable pads. Not only do you reduce waste, but you also save money because of their long life. Hygiene and freshness based on silver chloride (biocide active ingredient according to article 95 list) The absorbent layers of the SELENACARE products are equipped with the antimicrobial, biocidal protective finish SILVERPLUS® from RUDOLF GROUP. It prevents the proliferation of odour-causing bacteria. SILVERPLUS® is the leading silver ion technology and is certified according to the OEKO-TEX® Standard 100. OEKO-TEX guarantees that all components have been tested for harmful substances and that the product is harmless to health.
