How to Use Glycolic Acid in Your Skincare Routine

What is Glycolic Acid and Why Should You Use It?

Glycolic acid is the smallest of all alpha hydroxy acids, which are acids used in skincare for exfoliation. Since its molecule size is so small, glycolic acid can reach deep into pores and sweep away dead skin cells and unclog pores.

This helps to speed up cell turnover, which supports a fresh and radiant complexion and a host of other skincare benefits.

If you are wondering how to use glycolic acid in your skincare routine, in this post, we’ll review how to incorporate a glycolic acid product into your routine and look at some fantastic affordable glycolic acid products.

The Benefits of Glycolic Acid

What does glycolic acid do? Well, brighter fresher skin is just the start when it comes to the benefits of glycolic acid.

• Glycolic acid stimulates collagen production which helps the skin become firmer while minimizing fine lines and wrinkles. If used consistently, glycolic acid can noticeably reduce the signs of aging.
• Glycolic acid clears out pores which can lead to reduced breakouts and acne.
• Glycolic acid improves skin texture revealing a smoother and more even complexion.
• Glycolic acid improves skin tone helping to minimize discoloration, dark spots, and hyperpigmentation.

Glycolic Acid and Skin pH

The pH of a glycolic acid product will affect how your skin responds. A lower pH means that it is more acidic, and while it may be more effective, essentially it is more irritating.

On the other hand, if the pH of the glycolic acid product is too high, glycolic acid could be neutralized. So the trick is finding a balance between effectiveness and irritation.

Skincare products containing glycolic acid range in concentration from under 10% to as high as 30%. Look for lower concentrations if you are a beginner glycolic acid user to see how your skin responds.

Glycolic acid at 10% or less and a pH is 3.5 or higher is generally considered the optimal concentration, per FDA guidelines.

How to Add Glycolic Acid to Your Skincare Routine

When To Use Glycolic Acid?

In regard to the time of the day to use glycolic acid, it is best used at night, when your skin will not be exposed to the sun.

If you do use glycolic acid in the morning, be sure to apply a broad-spectrum sunscreen with an SPF 30 or higher.

When first starting out with glycolic acid, start slowly to see how your skin responds.

Since it is a chemical exfoliant, glycolic acid can cause some tingling or itchiness, but it should not cause burning and redness.

Apply your glycolic acid product of choice during the step of your skincare routine that you would normally use that type of product.

For instance, if you are using a glycolic acid toner, use it right after cleansing your skin.

If you are using a glycolic acid serum, use it in the serum/treatment step of your skincare routine after cleansing and toning and before your moisturizer.

What To Use After Glycolic Acid?

If you use a glycolic acid toner, follow it with hydration and moisture. Consider using a hydrating serum, such as this one, that contains hyaluronic acid for hydration and ceramides to replenish the delicate skin barrier.

If you have sensitive skin, consider using a serum that contains soothing ingredients like aloe vera, Centella asiatica, allantoin, or chamomile.

Regardless of the type of glycolic acid product that you use, be sure to follow with a moisturizer that locks in moisture and soothes your skin.

Glycolic acid can be drying, so a rich moisturizer at the end of your skincare routine will help to offset this side effect of glycolic acid.

Effective (and Affordable) Glycolic Acid Products

Glycolic acid is available as an ingredient in a wide range of skincare products, such as cleansers, toners, serums, peels, masks, and creams.

Please note that only one of the following glycolic acid products should be used at the same time.

Here are a few effective and affordable glycolic acid products:

This is the ideal introduction to glycolic acid since this toner’s formula isn’t too strong at 7%, but it’s still very effective and affordably priced. It really helps to improve skin texture and tone.

Plus, it helps to reduce breakouts and acne scars. For more on this acid toner, please see my The Ordinary glycolic acid toner review.

They also note that this toning solution should not be used on sensitive, peeling, or otherwise compromised skin.

I have somewhat sensitive skin, and this toner causes a tingling and itchy sensation for a few minutes after application.

Glycolic Acid Side Effects

While there are many benefits of glycolic acid in skincare, it is important to note that there are some drawbacks when it comes to using glycolic acid on your skin.

Because glycolic acid has the smallest molecule size of all alpha hydroxy acids it can be the most effective, yet it also can be the most sensitizing.

Those with sensitive skin may experience redness, irritation, and dryness when using glycolic acid.

So while glycolic acid is good for normal, oily, and combination skin types, those with sensitive skin should be careful when it comes to glycolic acid.

Glycolic acid (and all alpha hydroxy acids) makes your skin more sensitive to the sun’s UV rays, so it is very important to wear a broad-spectrum sunscreen of SPF 30 or higher when using glycolic acid and for a week after.

Can You Use Glycolic Acid with Retinol or Other Acids?

When determining whether or not to use glycolic acid with other potent actives like retinol, vitamin C, salicylic acid, or lactic acid, it really comes down to the formulas of the products.

Please note that these are general guidelines and depend on your skin type.

Combining Glycolic Acid with Other Alpha Hydroxy Acids (AHAs)

In general, it is best to stick to applying one glycolic acid (direct acid) product at a time, as combining a glycolic acid product with other exfoliating acids, like lactic acid, may cause irritation and redness.

With that being said, some glycolic acid products are formulated with more than one alpha hydroxy acid for optional performance.

These products are formulated with the proper percentages of acids so that they don’t over-irritate the skin.

These multi-acid products can be effective depending on your skin tolerance.

Combining Glycolic Acid with Salicylic Acid

Glycolic acid and other alpha hydroxy acids are water-soluble, whereas salicylic acid, a beta hydroxy acid, is oil soluble.

So while glycolic acid is excellent for treating dull uneven skin, salicylic acid is excellent for reducing oil production, which can lead to acne.

Glycolic acid and salicylic acid can be combined, depending on your skin tolerance.

There are many products on the market that combine AHAs and BHAs at optimal percentages and with added ingredients like hyaluronic acid and emollients to minimize irritation.

Combining Glycolic Acid with Retinol

Using glycolic acid and retinol at the same time can be irritating. Retinol and glycolic acid both increase cell turnover and both have the ability to irritate and dry out your skin.

Also, each product may decrease the potency of the other product, since they are formulated to work at specific pH levels.

Your best bet would be to alternate the usage of products containing these ingredients on different nights. Or, use glycolic acid in the morning and retinol at night.

Combining Glycolic Acid with Vitamin C

Vitamin C, or L-Ascorbic Acid, is formulated at a specific pH for effectiveness. Combining glycolic acid with vitamin C will risk losing the potency of vitamin C.

Try using vitamin C products in the morning and glycolic acid products in the evening.
