What Does Glycolic Acid Actually Do? All You Need To Know
If you know anything about skincare, you’ll know that glycolic acid has been a trending ingredient for some time now, and this certainly doesn’t look set to change. Hailed as a hero alpha-hydroxy-acid (AHA), glycolic acid is the most popular and most researched AHA, with the most proven skin benefits.
From glycolic acid serums, to glycolic acid toners and glycolic acid creams, this amazing active can be found in all manners of skincare products. A plethora of studies have proved how effective glycolic acid is at rejuvenating the skin and it is regularly praised by editors and influencers for its multifaceted benefits. But, what does it actually do?
What Is Glycolic Acid?
Glycolic acid is an alpha-hydroxy acid derived from sugar cane. Of all the AHAs, it has the simplest structure and the smallest molecules; meaning that it is easily absorbed and able to effectively penetrate the deepest layers of the skin.
What Does Glycolic Acid Do?
The main function of glycolic acid is to exfoliate the skin by essentially ‘ungluing’ dead cells from each other and removing them from the skin. It gently resurfaces the skin, making way for newer, fresher skin cells whilst kick-starting cellular regeneration. Due to its small chemical structure, glycolic acid gets deep into the skin, where it stimulates the production of collagen and elastin.
What Are The Benefits Of Using Glycolic Acid?
Glycolic acid for skin has numerous benefits including:
- Fighting acne
- Improving scarring
- Minimising the appearance of pores
- Reducing fine lines and wrinkles
- Fading dark spots and hyperpigmentation
- Evening out skin tone
- Brightening the skin
How Do You Use Glycolic Acid In Your Skincare Routine?
It’s important to be mindful of the fact that less is more when it comes to glycolic acid; using too many products that contain the powerful ingredient could lead to irritation or even damage your skin. If you have sensitive skin, start with a glycolic acid cleanser to get your skin used to the active, rather than jumping straight into leave-on glycolic acid products.
Glycolic acid makes your skin more sensitive to sunlight so make sure that you use sun protection when using this active. Also, avoid using other AHAs or products containing vitamin A (such as retinol), as your skin may become sensitive or irritated.
Is Glycolic Acid Suitable For All Skin Types?
Whilst glycolic acid is generally well tolerated, it’s most suited to those with normal, combination and oily skin. If you have dry, or sensitive skin you need to implement glycolic acid into your skincare regime with caution as it may cause irritation. If you have rosacea or eczema it’s best to avoid glycolic acid products.
