Retinol vs Glycolic Acid
Retinol has long been hailed as the ultimate ingredient for smoother, younger-looking skin, but it comes with many side effects and complications. Many users can experience irritation, flaking, and there is a long adjustment period before seeing visible results in your skin changes. If you have struggled with how to use retinol, or are looking for a gentler, more reliable alternative, then you should consider glycolic acid.
What Glycolic Acid Does for Skin
If you’re wondering ‘What does Glycolic acid do for skin?’ You might be surprised to know that we are often asked the same question. So, we’ve put together a series of blogs, to help you understand how Glycolic acid works, how to use it, and what types of skin can benefit from regular Glycolic Acid usage.
Simply put, it delivers visible results quickly, helping to resurface the skin, brighten dull complexions, and reduce fine lines without disrupting the skin barrier. Unlike retinol, it does not increase sun sensitivity, making it a safer choice for your daily skincare routine.
Glycolic Acid is an ideal option for those who spend a lot of time outdoors, whether skiing in harsh winter conditions, travelling to warmer climates, or simply enjoying an active lifestyle. By gently exfoliating the skin without causing excessive dryness or irritation, glycolic acid supports a balanced complexion without the risk of UV-induced damage that often accompanies retinol use.
Its flexibility also means it can be easily incorporated into a skincare routine without needing to pause treatments during the summer months or adjust for seasonal changes. For those who want an effective all-round product for radiant skin, glycolic acid provides both convenience and results.
Immediate Results
Retinol requires time and patience. Results can take months to appear, and during the adjustment period, many experience redness, peeling, and breakouts.
Unlike Retinol, Glycolic acid works from the first use by exfoliating the skin’s surface to immediately reveal a brighter, smoother and glowing complexion.
Dr. Michelle Green, a board-certified dermatologist, explains, "Glycolic acid is one of the most effective alpha hydroxy acids for improving skin tone and texture. It works quickly and does not require a long adaptation period like retinol."
No Retinol Purge or Harsh Side Effects
One of the most frustrating aspects of retinol is the purge phase, where breakouts, flaking, and irritation occur before improvements are visible. Glycolic acid does not cause purging in the same way, making it a more predictable option for those who want smoother, clearer skin without the discomfort.
Safe for More Skin Types
Retinol is often too harsh for sensitive or reactive skin, leading to redness and discomfort. Glycolic acid, when used at the right concentration, is better tolerated and can be adjusted to suit different skin needs.
According to dermatologist Dr. Hadley King, "For those with sensitive skin who cannot tolerate retinoids, glycolic acid is a fantastic alternative that still offers anti-aging and brightening benefits."
Works with Your Existing Skincare Routine
Retinol comes with a long list of ingredient restrictions. It should not be mixed with vitamin C, exfoliating acids, or certain peptides, making it difficult to incorporate into a routine. Glycolic acid is far more flexible and can be used alongside other products in your daily skincare rituals.
Retinol and Sun Damage
One of the biggest drawbacks of retinol is that it makes the skin significantly more sensitive to sunlight. Even small amounts of sun exposure can lead to increased pigmentation, redness, and irritation. This means anyone using retinol must commit to strict sun protection, which is often overlooked, resulting in more skin damage.
A study published in the Journal of Investigative Dermatology found that retinoids weaken the skin’s natural barrier function, making it more vulnerable to UV damage. Over time, this can lead to premature aging rather than actually preventing it.
One of the many benefits of Glycolic acid is that it does not make the skin as photosensitive. While SPF is always recommended for healthy skin, glycolic acid users will not experience the same level of sun-related irritation and damage as those using retinol.
The science of Glycolic Acid in skincare
Glycolic acid is an alpha hydroxy acid (AHA) which is naturally derived from sugarcane. It dissolves the bonds between dead skin cells, allowing them to shed naturally. This process encourages fresh, new skin to surface, reducing dullness, fine lines, and uneven texture.
Key Benefits of Glycolic Acid
-
Exfoliates and smooths skin for a fresher, more even tone
-
Reduces fine lines and wrinkles without causing excessive irritation
-
Helps fade pigmentation and dark spots without increasing sun sensitivity
-
Unclogs pores and minimises breakouts
-
Boosts hydration by improving skin’s ability to absorb moisture
How to Use Glycolic Acid for Best Results
Start slowly, and introduce Glycolic Acid gradually. Start building it into your daily skincare ritual two to three times a week and increase usage as required.
Pair it with Hydration
Glycolic acid removes dead skin cells, allowing hydrating ingredients to penetrate more effectively. Use it alongside a nourishing moisturiser or oil.
Apply in the Evening
Like retinol, glycolic acid is most effective when used at night, allowing the skin to regenerate while you sleep.
Always Wear SPF
While glycolic acid does not make the skin as sun-sensitive as retinol, daily SPF is still essential for overall skin health.
Should I Use Glycolic Acid Instead of Retinol?
If you’ve answered ‘yes’ to any of these, then Glycolic Acid could be a better skincare staple in your daily beauty ritual.
