A Guide to Using Glycolic Acid in Your Skincare Routine

Glycolic acid has become a bit of a superstar in the skincare world – and for good reason. It’s known for giving your skin that fresh, post-facial glow while helping with everything from breakouts to dark spots. But as effective as it is, glycolic acid is also a powerful active ingredient, and it can have adverse effects when used incorrectly.

This is why it’s vital to understand how it works and how to use it safely, especially if you have sensitive skin or are already using prescription skin care. In this guide, we’ll explain how glycolic acid works, how to use it in your routine, the benefits, and who should and shouldn’t use it.  

What is Glycolic Acid and How Does It Work?

Derived from sugarcane, glycolic acid is part of the AHA (alpha hydroxy acid) family. It works by exfoliating the outer layer of dead skin cells to encourage fresh, new cells to come to the surface. The result is smoother texture, fewer dark spots, and a brighter, more even complexion.

Because of its small molecular size, glycolic acid penetrates the skin much deeper than other AHAs. This is great for effectiveness, but it also means it’s more likely to cause irritation if it is overused, especially for those with reactive or delicate skin.

How to Use Glycolic Acid in Your Routine  

If you’re new to glycolic acid, it’s important to remember slow and steady wins the race. Here’s how to ease it into your routine the right way:  

Apply at night:

Your skin goes into repair mode overnight, which makes it the ideal time to use exfoliants.  Applying glycolic acid in the evening allows it to work in sync with the natural renewal process of your skin.  

Start with a low concentration:

If you’ve never used acids before or you’re already using prescription skincare, like prescription anti wrinkle cream, it’s best to begin with a low-strength glycolic acid (around 5%) just a couple of times a week. This will help your skin adjust gradually before increasing frequency or strength.

Allows follow with a moisturiser:

As glycolic acid exfoliates the skin, it can temporarily disrupt your skin barrier. It’s crucial to follow with a moisturiser to lock in hydration and soothe the skin while reducing the risk of tightness, dryness, and irritation.

Never skip SPF:

Glycolic makes your skin more sensitive to sunlight, even on cloudy days. By using a broad-spectrum SPF daily, you can prevent further pigmentation, inflammation, and UV-damage.  

Avoid combining with strong actives:

Unless your skincare routine has been professionally designed like the routines here at MiQuest, avoid using glycolic acid alongside other potent ingredients like retinol, salicylic acid, or strong exfoliating masks. Layering too many actives can overwhelm your skin and undo your progress.  

What are the Benefits of Glycolic Acid?  

When it’s used properly, glycolic acid can do a lot for your skin:

• Smooths uneven texture by removing build-up
• Fades pigmentation and post-inflammatory marks  
• Brightens dull skin and brings back natural glow  
• Improves fine lines and wrinkles  
• Enhances product absorption

Who Should (and Shouldn’t) Use Glycolic Acid?

Glycolic acid is perfect for anyone dealing with:

• Pigmentation or dark spots  
• Rough or uneven skin texture
• Dullness or lack of glow  
• Early signs of ageing  

However, for those with very sensitive skin, a compromised barrier, or conditions like rosacea, should take caution. It doesn’t mean you can’t use glycolic acid, but it should be balanced with calming ingredients and used in the right strength.  

Effective Skincare Begins with Personalisation  

Glycolic acid can be a real game-changer for improving your skin tone, texture, and glow – but only when it’s used right.
