In the world of skincare, AHAs are a buzzword you've likely heard. But what are AHAs, and why are they so popular?

AHAs, or Alpha Hydroxy Acids, are powerful ingredients found in many skincare products. They're known for their ability to exfoliate the skin, promoting a smoother, brighter complexion.

But there's more to AHAs than just exfoliation. They can also help address common skin concerns like fine lines, wrinkles, and age spots. Plus, they can even improve mild hyperpigmentation and acne scars.

In this guide, we'll delve into the world of AHAs. We'll explain what they are, how they benefit your skin, and how to use them safely. We'll also highlight some popular AHA skincare options from Dermalogica.

What Are AHAs?

AHAs, short for Alpha Hydroxy Acids, are a group of natural acids found in various foods. They've gained popularity in skincare due to their exfoliating properties. But how do they work?

AHAs work by loosening the bonds between dead skin cells. This process promotes cell turnover, leading to the removal of dead skin cells from the skin's surface. The result? A smoother, brighter, and more even-toned complexion.

Here are some key facts about AHAs:

• They're derived from various sources, such as milk (lactic acid) or sugar cane (glycolic acid).

• They come in various forms, including cleansers, toners, serums, creams and chemical peels.

• The concentration of AHAs in skincare products can vary, although typically have less than 10% concentration for over-the-counter products.

• Professional treatments may contain higher concentrations of AHAs.

Also, while AHAs are beneficial, they can increase sun sensitivity. So, it's crucial to use sunscreen when using AHA products.

The Most Common Types of AHAs

There are several types of AHAs, each with its unique properties and benefits. The most common ones include:

• Glycolic Acid: Derived from sugar cane, it's the smallest AHA, allowing it to penetrate the skin deeply. It's excellent for addressing fine lines, wrinkles, and age spots.

• Lactic Acid: Derived from milk, it's a larger molecule, so it doesn't penetrate as deeply. It's gentler and great for sensitive skin.

• Citric Acid: Derived from citrus fruits, it's often used in lower concentrations. It's beneficial for balancing the skin's pH and enhancing overall skin health.

Understanding the specific benefits of different types of AHAs can help you choose the right product for your skin. Remember, it's always advisable to consult with a skin care professional before starting an AHA treatment, especially if you have sensitive skin.

The Benefits of AHAs in Skincare

AHAs offer a multitude of benefits for the skin, including:

• Promote cell turnover for smoother skin

• Brighten the complexion and improve skin tone

• Address fine lines, wrinkles, and age spots

• Help with mild hyperpigmentation and acne scars

• Increase skin's absorption of other skincare products

The benefits of AHAs are cumulative. Consistent use is key to seeing results. But, as with any active ingredient, it's important to introduce AHAs slowly into your skincare routine to allow your skin to adjust.

How AHAs Promote Healthy Skin

AHAs promote healthy skin by accelerating the skin's natural exfoliation process. They loosen the bonds between dead skin cells, allowing them to be easily sloughed off. This reveals the fresh, healthy skin underneath.

The removal of dead skin cells also helps to unclog pores, reducing the likelihood of breakouts. Plus, by removing the top layer of dead skin cells, AHAs can help your other skincare products penetrate more deeply. This can make them more effective.

How to Use AHA Products Safely

Using AHA products safely is crucial to avoid potential skin irritation. It's important to remember that AHAs increase sun sensitivity. Therefore, using sunscreen is a must when incorporating AHA products into your skincare routine.

Here are some key tips for using AHA products safely:

• Always use sunscreen, especially when using AHA products

• Start with a lower concentration and gradually increase

• Patch test a new AHA product to avoid potential irritation

• Avoid overuse of AHAs to prevent skin sensitivity

• Avoid using on broken or irritated skin

• Use the product once or twice a week to start, then gradually increase frequency

• Always follow the instructions on the product label

• Store AHA products away from direct sunlight and heat to maintain their efficacy

Here are some key factors to consider when choosing an AHA product:

• AHA concentration - start low

• Type of AHA used - match to your skin care goals

• pH level of the product - lower pH means it’s more acidic and potentially more potent.
