Our skin is the outermost layer of our body, the part that protects everything there is within. And in doing so, it comes in direct contact with all external elements, like sun, heat, dryness, and humidity. As a result, it gets affected the most!


And even if your skin is all plump and glowy, after a certain age, it starts showing signs of aging and gets rough, dry, and dull. While we cannot reverse the aging process, we can definitely slow it down! 


How, you ask? 


By following a regular skincare routine! 


However, you will find many products out there that claim to solve all your skincare issues, leaving you contemplating which one to use.


And most importantly, do you have to buy a dozen different products and spend half the day applying and reapplying them on your face? 


The answer is NO! 


Because, what we’re going to tell you, is something that will save you time and money and do wonders for your skin. 


We’re going to tell you about mandelic acid and introduce you to mandelic acid products that actually work. 

So, what exactly is mandelic acid?


What is Mandelic Acid? 

Mandelic acid is an alpha hydroxy acid (AHA) obtained from bitter almonds. It is a relatively new-found ingredient, but research shows that it is quite beneficial for our skin as it targets some of the most common pain points of human skin, like acne, dark spots, and signs of aging. 


For years, this amazing multi-beneficial ingredient has been used as peels in professional setups by licensed estheticians; however, lately, it has made its way into over-the-counter serums and exfoliants for personal use as well. 


Let’s have a look at some benefits of mandelic acid.

Benefits of Mandelic Acid

As we mentioned earlier, mandelic acid targets a number of common skin problems. 


Here’s a rundown of all the skin issues that get better when using mandelic acid products:


  • It helps fight acne and reduces acne scars.
  • It evens out your skin tone.
  • It promoted collagen production.
  • It reduces hyperpigmentation.
  • It helps remove dead skin cells and promotes the growth of new ones.
  • It reduces signs of aging by targeting fine lines and giving the skin a youthful appearance.


While mandelic acid has so many benefits, most people face an issue! 


When they search the web or visit a skincare product shop, they come across many mandelic acid products; however, not all are authentic, and not all give them the desired results.


This brings us to the million-dollar question: Which mandelic acid products should you use?


After a lot of research and trying out several serums and skincare products containing mandelic acid, we found one product that actually worked: 20% Mandelic Acid by ERH

ERH’s 20% Mandelic Acid

20% Mandelic Acid by ERH is a serum that contains not only mandelic acid but several other ingredients that help with the 4 most common skin issues, including rough, oily, dull, and sagging skin. 


The serum is easy to apply and instantly penetrates into the epidermis or stratum corneum, which is the outermost layer of the skin. 

The result? 

  • Increased metabolism of dead skin cells.
  • Rebalanced sebum production.
  • Tightened pores.
  • Excessive oil reduction.
  • Reduced acne production.
  • Restored water and oil balance of the skin.

Plus, it helps absorb other skincare products into the skin for optimum results!


The best part about 20% Mandelic Acid is that people with all skin types can use it. So, whether you have oily skin, dry skin, dull skin, skin with large and clogged pores, skin with acne scars, uneven skin tone, dark spots, or any other issue, this product is suitable for all.

Ingredients of ERH Mandelic Acid

20% Mandelic Acid does not comprise solely of mandelic acid, but 3 other ingredients as well that work together to make your skin look and feel better. 

1. Mandelic Acid 

This serum’s first and most important ingredient is 20% mandelic acid. This ingredient is a kind of lipophilic acid that mild yet highly effective. Some of its features are:


  • It is gentle on the skin. This makes it an ideal choice for people with sensitive skin, as they can easily use it without fearing irritated skin or getting a reaction.


  • It accelerates cell turnover. In other words, it improves your skin’s metabolism by removing dead skin cells and replacing them with new ones.


  • It helps with collagen production, the main protein found in our skin and tissues, improving your skin’s appearance.


  • It regulates sebum production, which reduces acne breakouts.


  • It has an exfoliating action that helps remove dead skin, leaving smoother and softer skin. 


  • It reduces hyperpigmentation caused by melasma by lightening dark spots.


  • It has anti-aging properties that reduce fine lines and wrinkles, giving your skin a youthful look. 

2. Vitamin C

Vitamin C is another vital ingredient in ERH’s 20% Mandelic Acid serum. 



  • It hydrates your skin, giving it a plump and fresh appearance. 


  • It has a brightening effect by reducing melanin production. This can also help with hyperpigmentation and dark spots.
  • It has anti-inflammatory properties that reduce redness and irritated skin, promoting an even skin tone. 
  • It plumps and hydrates the under-eye area by reducing and smoothing out fine lines. 

3. Arginine 

Arginine is an amino acid that builds protein in our body. 




The inclusion of this ingredient in 20% Mandelic Acid serum helps with the following:


  • It hydrates and moisturizes the skin to keep it smooth, firm, and plump.
  • It restores skin moisture and makes dull and dry skin appear fresh.
  • It has anti-aging effects that reduce the appearance of fine lines and wrinkles. 
  • It strengthens the skin’s protective barrier to prevent damage caused by free radicals.

4. Glycerin 

Glycerin is a natural compound extracted from vegetable oils or animal fats. It is an excellent ingredient to keep your skin healthy. 




Some of its properties are:


  • It provides nourishment and hydration to your skin by drawing in moisture from the air and locking it in. 


  • It is thick and syrupy, which means it stays on the skin for a longer time, preserving skin moisture and keeping it from drying out even if you live in a dry region with low humidity levels.
  • It enhances skin elasticity by helping the natural skin lipids to retain their structure.
  • It keeps the skin cuticles soft due to its emollient properties. 

How Does 20% Mandelic Acid Help Your Skin?

The collaborative result of the 4 main ingredients of 20% Mandelic Acid by ERH target 4 different kinds of skin problems:

1. Dehydrated and Rough Skin 

Dead skin cuticles lead to a reduced skin cell turnover, which means that your skin is unable to remove dead skin cells to give way to new ones. This causes your skin to appear rough and dehydrated. 


20% Mandelic Acid helps increase skin metabolism by removing dead skin cells, resulting in brighter and smoother skin. The glycerin and arginine also work with the mandelic acid to retain skin moisture and make it supple and fresh. 

2. Oily Skin and Clogged Pores

Our skin naturally produces sebum, which is an oily wax-like substance. However, the overproduction of this skin sebum can lead to skin with excessive oil that further causes clogged pores. 


20% Mandelic Acid works by rebalancing sebum production, reducing oily skin, and opening up clogged pores for your skin to breathe!

3. Dull Skin

Dead skin cells not only make our skin rough and dry but also make it appear dull and dark. Plus, hyperpigmentation and black spots worsen the situation.


20% Mandelic Acid removes dead skin cells to bring out fairer and flawless skin. The vitamin C in the serum works side by side with mandelic acid to brighten dark spots and reduce hyperpigmentation, giving way to radiant and translucent skin.

4. Wrinkles and Sagging Skin 

Aging is imminent! However, we can stop its early onset and keep our skin plump and youthful for longer.


20% Mandelic Acid with vitamin C, arginine, and glycerin locks in moisture, removes dead skin cuticles and promotes collagen production to keep the skin fresh and hydrated. As a result, it restores our skin’s elasticity and softens fine lines and wrinkles, making it look fresh, supple, and youthful.
