Glycolic Acid (AHA): The Ultimate Guide to Radiant, Youthful Skin

Glycolic acid, an alpha hydroxy acid (AHA), is one of the most effective and widely used ingredients in skincare. Despite the intimidating name, glycolic acid is gentle, safe, and incredibly beneficial for your skin when used correctly. At Paula’s Choice, we offer a range of glycolic acid products designed to exfoliate, hydrate, and rejuvenate your complexion. In this comprehensive guide, we’ll explore everything you need to know about glycolic acid, including its benefits, how it works, and how to incorporate it into your skincare routine.

What is Glycolic Acid (AHA)?

Glycolic acid is a type of alpha hydroxy acid (AHA) derived from sugarcane. It is the smallest molecule in the AHA family, which allows it to penetrate the skin more effectively than other AHAs. This makes it a powerful exfoliant that works on the skin’s surface to remove dead skin cells, improve texture, and reveal a brighter, more youthful complexion.

Key Properties of Glycolic Acid:

• Exfoliating: Breaks down the bonds between dead skin cells, promoting cell turnover.
• Hydrating: Helps the skin retain moisture by improving its natural barrier function.
• Brightening: Reduces the appearance of dark spots and uneven skin tone.
• Anti-Aging: Stimulates collagen production, reducing the appearance of fine lines and wrinkles.

Why Use Glycolic Acid for Skin?

Glycolic acid is a multitasking ingredient that addresses a wide range of skin concerns. Here’s why it’s a must-have in your skincare routine:

1. Exfoliates Dead Skin Cells

Glycolic acid gently removes the top layer of dead skin cells, revealing smoother, softer skin underneath. This process helps improve skin texture and tone, making it ideal for those with dull or rough skin.

2. Hydrates Dry Skin

Unlike harsh physical exfoliants, glycolic acid exfoliates without stripping the skin of its natural moisture. It also enhances the skin’s ability to retain water, making it particularly beneficial for dry or dehydrated skin.

3. Brightens Skin Tone

By promoting cell turnover, glycolic acid helps fade dark spots, sun damage, and hyperpigmentation. Regular use can result in a more even, radiant complexion.

4. Reduces Signs of Aging

Glycolic acid stimulates collagen production, which helps reduce the appearance of fine lines and wrinkles. It also improves skin elasticity, giving your skin a firmer, more youthful appearance.

5. Enhances Skincare Product Absorption

Exfoliating with glycolic acid allows your other skincare products, such as serums and moisturizers, to penetrate more effectively. This maximizes their benefits and improves overall results.

Different types of AHAs

BHA exfoliants clean deep inside your pores while AHA exfoliants mainly work on the skin's surface making them particularly suitable for dry skin. This helps the skin to hold onto more moisture. There are various alpha hydroxy acids (AHAs): glycolic acid, lactic acid, malic acid, tartaric acid, citric acid and mandelic acid. Read on to discover the difference between these acids and how glycolic acid products work for dry skin.

At Paula’s Choice, we offer a range of glycolic acid products tailored to different skin types and concerns. Our formulas are gentle yet effective, making them suitable for daily use.

How Does Glycolic Acid (AHA) Work?

Glycolic acid works by breaking down the bonds between dead skin cells, allowing them to shed more easily. This process not only exfoliates the skin but also stimulates cell turnover, revealing fresher, brighter skin. Its hydrating properties help improve the skin’s natural barrier function, making it more resilient and better able to retain moisture.

The Science Behind Glycolic Acid:

• Penetrates the Skin’s Surface: Its small molecular size allows it to penetrate deeply into the skin.
• Promotes Cell Turnover: Encourages the shedding of dead skin cells and the growth of new ones.
• Boosts Hydration: Improves the skin’s ability to retain moisture.
• Stimulates Collagen Production: Helps reduce the appearance of fine lines and wrinkles.

How to Use Glycolic Acid Products

If you’re new to glycolic acid for face, it’s important to introduce it gradually to avoid irritation. Follow these steps to incorporate it into your routine:

Step 1: Start Slowly

Begin by using a glycolic acid exfoliant twice a week, gradually increasing to once or twice daily as your skin adjusts. This helps your skin build tolerance and minimizes the risk of irritation.

Step 2: Apply After Cleansing and Toning

After cleansing and toning, apply your glycolic acid product. For liquid exfoliants, use a cotton pad. For gels or lotions, apply with your fingertips.

Step 3: Target Problem Areas

Spread the product evenly over your face, including the eye area (avoiding the lower lash line and eyelids). If you have specific areas of concern, such as dark spots or uneven texture, you can apply a second layer to those areas.

Step 4: Follow Up with Moisturizer and Sunscreen

Do not rinse off the product. Continue with the rest of your skincare routine, including moisturizer and sunscreen during the day. Sunscreen is especially important because exfoliation can make your skin more sensitive to the sun.

Benefits of Regular Exfoliation with Glycolic Acid

Regular use of glycolic acid products can transform your skin. Here are some of the key benefits:

1. Smoother Skin Texture

By removing dead skin cells, glycolic acid helps smooth rough, uneven skin, leaving it soft and supple.

2. Brighter, More Even Skin Tone

Glycolic acid fades dark spots, sun damage, and hyperpigmentation, resulting in a more radiant complexion.

3. Reduced Signs of Aging

Stimulating collagen production, glycolic acid helps reduce the appearance of fine lines and wrinkles, giving your skin a firmer, more youthful appearance.

4. Improved Hydration

Glycolic acid enhances the skin’s natural barrier function, helping it retain moisture and stay hydrated.

Different Types of AHAs

While glycolic acid is the most popular AHA, there are several other types of alpha hydroxy acids, each with its own unique benefits:

1. Lactic Acid

Derived from milk, lactic acid is gentler than glycolic acid and is ideal for sensitive skin. It also has hydrating properties.

2. Mandelic Acid

Derived from almonds, mandelic acid has a larger molecular size, making it less irritating and suitable for sensitive skin.

3. Malic Acid

Found in apples, malic acid is a mild exfoliant that also has antioxidant properties.

4. Tartaric Acid

Derived from grapes, tartaric acid helps improve skin texture and tone.

5. Citric Acid
