Glycolic Acid Vs. Salicylic Acid: What's The Difference?

Find out which one is right for your skin

Rachel Baker

There was a time when the sole purpose of using skincare products was to derive superficial results that lasted for a short duration. But with the passage of time and the influx of information on the internet, we’re now more mindful of the ingredients in our skincare products, along with the benefits they provide. Skincare acids, primarily, have been receiving a lot of love thanks to their ability to seep deeper into the skin and repair it from within. However, with the number of acids out there, it can easily get confusing as to which acid to pick for your skin concern. But worry not, we’re here to relieve your dilemma. Ahead, we’re listing down the differences between two of the most popular acids - Glycolic Acid vs. Salicylic Acid. Read on for the low down…

What Is Glycolic Acid?
Glycolic Acid is naturally derived from Sugarcane, but can also be developed in a lab. Thanks to its small molecular size, it can easily penetrate into the deeper layers of your skin and perform its magic. This AHA (Alpha Hydroxy Acid) is widely known to slough off dead skin cells, thus revealing brighter, smoother skin underneath. Glycolic Acid also has anti-aging and hydrating qualities making it a popular ingredient in moisturizers and serums.
Benefits Of Glycolic Acid

This hero ingredient comes packed with several benefits.

Lightens dark spots and pigmentation caused due to UV rays and acne

Minimizes the appearance of pores.

Reduces acne breakouts.

Refines fine lines and wrinkles.

Firms the skin.

Stimulates Collagen production.
Recommended For

Glycolic Acid is often recommended for people who have pigmented skin, acne-prone skin, or aging skin. As with any skincare acid, it’s best to introduce this product slowly into your routine or it may cause skin irritation. Start with a lower concentration, between 5-10%, and gradually increase it. Glycolic Acid can increase the skin’s sensitivity to the sun, so always wear sunscreen after applying Glycolic Acid to prevent sun damage.
What Is Salicylic Acid?
Salicylic Acid is naturally derived from the bark of willow trees and wintergreen leaves. It can also be artificially created in a lab. This BHA (Beta Hydroxy Acid) has powerful exfoliating properties. It stops excess sebum production in its track and unclogs the pores like no other. Additionally, it also contains anti-bacterial and antimicrobial properties. This is why Salicylic Acid is majorly used in anti-acne products and treatments.
Benefits Of Salicylic Acid

Apart from getting rid of excess sebum and unclogging the pores, Salicylic Acid also delivers the following benefits:

Prevent acne breakouts

Fights whiteheads

Improves skin texture

Fades hyperpigmentation

Calms inflammation

Due to its benefits, Salicylic Acid is usually recommended for people with acne-prone skin. However, it’s notorious for causing dryness and irritation in some people. That’s why it’s best to consult a dermatologist before introducing this ingredient to your skincare routine. Also, always follow up the application with generous amounts of sunscreen to prevent sun damage.
So, What’s The Difference Between Glycolic Acid And Salicylic Acid?
The primary difference between Glycolic Acid and Salicylic Acid is its size. The former has a smaller molecular size and penetrates deeper into the skin. While Salicylic Acid has a larger molecule and stays on the surface of the skin. While both have exfoliating benefits, Salicylic Acid is considered the better choice since it reduces excess sebum production, which is the root cause of acne breakouts.
