AHA und BHA – deine einfache Einführung in zwei wichtige Pflege-Säuren KI-generiert

AHA and BHA – your simple introduction to two important skincare acids

in Article

If you've ever wondered what AHA and BHA actually are and why AHA and BHA appear everywhere in skincare, you're in the right place. Just like with vegan skincare, these ingredients are not about marketing buzz but about real scientifically known properties that can help you better understand your skin and make more targeted routine decisions.

 

What does AHA actually mean?

AHA stands for Alpha Hydroxy Acids – a group of water-soluble acids often derived from natural sources like sugarcane or milk. The most well-known are glycolic acid and lactic acid.

These ingredients primarily work on the surface of the skin by loosening and gently removing dead skin cells. This supports the natural renewal process and results in a smoother skin texture.

In practice, you will find AHA in serums, toners, or exfoliants, which are mainly formulated for normal to dry skin.

 

And what is BHA?

BHA stands for Beta Hydroxy Acids, with the most well-known form in cosmetics being salicylic acid. Unlike AHA, BHAs are oil-soluble, which means they can penetrate deeper into oil-rich areas.

This allows BHA products to work where oil and other residues accumulate in the pores, so they are often used in formulations for oily or combination skin.

Especially if you want to know how BHA/salicylic acid can reduce blemishes, it's worth checking out our detailed article "Salicylic Acid (BHA) – The Miracle Cure for Blemishes" about this active ingredient. 

 

AHA and BHA – what is the difference?

Although AHA and BHA both belong to the so-called chemical exfoliants, meaning they dissolve dead skin cells instead of scrubbing them off mechanically, there are clear differences in solubility and areas of application:

  • AHAs are water-soluble and primarily act on the skin’s surface.

  • BHAs are oil-soluble and can work in pore areas where oil and dirt accumulate.

Simply put: AHA is more suitable for texture and surface care, while BHA targets areas where oil and deeper skin layers play a role.

 

How are AHA and BHA used in skincare?

Today, you can find AHA and BHA in many different skincare products, from cleansers to serums to leave-on exfoliants.
The great thing is: you can basically integrate AHA and BHA into a skincare routine. Many people start with a mild formulation and observe how their skin reacts before expanding use.

A tip: Since chemical exfoliants can make the skin more sensitive to UV light, it’s worth paying attention to good sun protection during the day. This helps your skin maintain a balanced appearance.

 

Conclusion: AHA and BHA clearly explained

AHA and BHA are not magic words but well-researched ingredients with clearly defined properties. While AHA acids mainly work on surface and texture, BHA penetrates somewhat deeper into oily areas.

Both acids can be sensibly used in skincare routines according to personal needs and preferences. The most important thing is to choose products that suit your skin type and to integrate AHA and BHA gently into your routine.

Hormonal acne – what is behind hormonally caused skin blemishes?

Blemishes do not only occur during puberty. Pimples and an unsettled skin appearance can also occur in adulthood, often during phases of hormonal changes. That is why it is often referred to as hormonal acne or hormonally induced skin blemishes. But how can you recognize hormonally induced skin changes and what role does the right skincare play?   What is hormonal acne? The term hormonal acne is often used when blemishes are associated with hormonal fluctuations. Such changes can occur, for example, during the menstrual cycle, pregnancy, menopause, or other life phases with altered hormone activity. Since skin changes can have many causes, it is not possible to determine the cause solely based on the skin's appearance.   How can you recognize hormonally induced skin blemishes? Hormonally induced blemishes often appear in the lower face area, especially on the chin, jawline, and neck. It is also typical that they recur during certain periods. Possible characteristics include: recurring blemishes in the chin and cheek area, an unsettled skin appearance, individual inflamed pimples, a temporal connection with hormonal changes. These characteristics can have different causes and do not replace a professional diagnosis.   The right skincare for hormonally induced blemishes Although skincare does not influence hormonal processes, a routine tailored to your skin type can help your skin appear well cared for and balanced. Gentle cleansing A mild facial cleanser removes excess sebum, dirt, and makeup without unnecessarily stressing the skin. Too aggressive products can further burden the skin. Don’t forget moisture Even impure skin needs moisture. Light formulations with ingredients like Glycerin, Hyaluronic acid or Squalane provide a pleasant skin feel without unnecessarily weighing down the skincare routine. Support the skin barrier Skincare products with Ceramides or Niacinamide are often used to complement the skin’s protective barrier and support balanced skincare.   Which habits can be helpful? In addition to skincare, everyday habits can also help minimize stress on the skin: Thoroughly remove makeup in the evening, Avoid touching the face with your hands as much as possible, Gradually integrate skincare products into the routine, Apply sunscreen daily. A simple and consistent routine is often more effective than using many different products at the same time.   Conclusion Hormonal acne Hormonal or hormonally induced skin impurities can occur at different stages of life and are a part of everyday life for many people. With gentle cleansing, moisturizing care, and a well-coordinated routine, the skin can be optimally cared for and its natural protective function supported. Since the causes of skin changes can be very different, individual dermatological evaluation is recommended for persistent or severe complaints.

Treating acne scars – what your skin really needs now

Even when skin blemishes have long disappeared, they can leave visible marks. Small indentations, uneven skin textures, or darker skin spots continue to concern many people long after a phase of impure skin. Therefore, the question often arises: Can acne scars be treated? The answer is: It depends on the type of skin change. While some discolorations may fade over time, true scars usually remain permanent. However, with appropriate skincare, the skin’s appearance can be cared for and optimally supported.   What are acne scars? Acne scars form when the skin tissue changes after an inflammatory skin condition. Different types of scars can develop, such as depressed or raised scars. Not every discoloration after a pimple is a scar, though. Often, these are so-called post-inflammatory pigment changes that can become less visible over time.   Which skincare is suitable for acne scars? Although skincare cannot remove existing scars, it can help the skin appear well cared for and cosmetically support the natural skin renewal process. Gentle cleansing A mild facial cleanser removes dirt, excess sebum, and makeup without unnecessarily stressing the skin. Aggressive cleansing products are often not necessary. Moisture as a foundation Well-hydrated skin often appears more supple. Ingredients like hyaluronic acid, glycerin, and squalane support moisture supply to the upper skin layers and complement the daily care routine. Popular active ingredients Depending on skin type, the following ingredients are often integrated into the routine: Niacinamide – a versatile component of modern skincare. Vitamin C – a popular antioxidant for a fresh complexion. Retinol – commonly used in anti-aging and skincare products. Ceramides – support the natural skin barrier. New active ingredients should generally be introduced gradually.   Sunscreen is part of the daily routine UV radiation can affect the appearance of skin changes. Therefore, it is recommended to use sunscreen with adequate SPF as a fixed part of daytime skincare.   Patience pays off A regular skincare routine tailored to the skin type is often more effective than constantly changing products. Skincare takes time; visible changes in the skin’s appearance usually do not develop overnight.   Conclusion Those who want to treat acne scars should first distinguish between true scars and temporary skin discolorations. A balanced skincare routine with gentle cleansing, moisturizing ingredients, and daily sun protection can help the skin appear well cared for and more even. For pronounced or permanently existing acne scars, dermatological or cosmetic treatments may be considered. Which method is suitable should be assessed individually and professionally.

Hautbarriere reparieren – warum deine Haut manchmal einfach eine Pause braucht KI-generiert

Repairing the skin barrier – why your skin sometimes just needs a break

Does your skin suddenly feel dry, tight, or more sensitive than usual? Then it's worth taking a look at your skin barrier. It is your skin's natural protective layer and works daily, whether in wind, sun, dry heated air, or an intensive care routine. If it becomes unbalanced, it can quickly become noticeable. The good news: With gentle and appropriate skincare, you can help your skin regain its natural balance.   What exactly is the skin barrier? The skin barrier forms the outermost layer of your skin and performs an important protective function. It consists of skin cells and natural skin lipids that work together like a stable network. This helps the skin barrier retain moisture and fend off external influences. If this balance is disturbed, the skin can feel rough, dry, or sensitive. This is not necessarily a cause for concern; often the skin simply reacts to external stress or unfamiliar care.   What can cause the skin barrier to become unbalanced? Our skin is exposed to various influences every day. Common causes include: Too intensive cleansing Hot water or strongly degreasing cleansing products can unnecessarily stress the skin. Mild cleansing is often completely sufficient in everyday life. Too many active ingredients at once Peels, acids, or retinol have their place in skincare. However, using several intensive products at the same time can further stress the skin. Less is often more here. Environment and daily life Cold, dry air, UV radiation, or frequent hand washing are external factors that can stress the skin.   How you can support your skin barrier If your skin feels like it needs more care, often a simple routine helps more than a long list of products. Focus on moisture Ingredients like glycerin or hyaluronic acid support moisture supply to the upper skin layers and provide a pleasant skin feel. Supplement skin lipids Ceramides and squalane are popular ingredients in modern skincare. They also occur naturally in the skin and are often used in products to care for the skin's protective barrier. Give your skin time Not every change happens overnight. A consistent skincare routine tailored to your skin type can help support your skin's natural balance in the long term.   Conclusion The skin barrier does great work every day, so it's worth giving it the attention it deserves. Gentle cleansing, moisturizing care, and a simple routine are often the best foundation to support the skin's natural protective function. Sometimes your skin doesn't need extra steps, just the right care and a little patience.
