What Makes AHA Serums Essential & Unique
You’ve probably come across a ton of serums and creams that promises to give you that smooth, ageless Jennifer Lopez skin.
And if you’re like me, you’ve probably tried more than your fair share of fancy and expensive bottles.
This much is true: if you can invest in only one skincare product in your daily routine, it should be your serum.
Other steps like cleansing and moisturizing have functions that can be done effectively through products that won’t break the bank.
Serums, however, are made to be packed with a multitude of active ingredients whose sole goal is to nourish and restore your skin.
And you only want to feed your skin the best ingredients if you want effective and long-lasting results.
You’ll thank your skin when you’re 40 and don’t look a day over 30.
Your ideal serum should promote anti-aging, skin rejuvenation, and spot lightening among its laundry list of benefits.
And serums that have these inclusive sets of characteristics usually have a good dose of alpha-hydroxy acids in their formulation.
In this article, you’ll get a deeper understanding of how AHAs benefit your skin.
Most importantly, and this is where most people do it wrong, you’ll learn how to properly use and incorporate AHA serums into your daily skincare routine.
Once you have a grasp of these key points, you will not only maximize the benefits of alpha-hydroxy acids but also avoid the usual pitfalls most people that start using AHAs fall into.

Ask the Expert: What You Should Know Before Using AHAs
by SAMANTHA WELCH, ESTHETICIAN
Everyone’s skin is affected by the skin type we were born with, our hormones, the environment, the skincare, and the makeup we use on a daily basis–the list goes on.
However, having a good idea of what your skin needs and its current condition is crucial in picking the right products.
There are several things you should consider before delving into AHA serums.
When you’ve gone through these general guidelines, you’ll have a better chance of picking the right product for your skin and be able to reap all the benefits AHA serums have to offer.
Here are the basic guidelines for choosing the right AHA for your skin:
- Choose the right type of AHAs for your skin type to maximize its benefits.
Identify the skin issues you want to address and use the kind of AHA that would be most beneficial for your needs.
The list of products below identifies the AHAs active in each product, as well as outlines what type of skin issues it can address.
- Always use sunscreen once you start incorporating alpha-hydroxy acids in your skincare regimen.
All products with AHA results in UV sensitivity, so it is extremely important to use sunscreen during the day. This protects the skin from sun damage, which can lead to premature aging and skin discoloration.
Hyperpigmentation also can become more pronounced after sun damage, and a single day of sunburn can undo months of treatment.
- Be aware of your skin’s sensitivity or resilience to active ingredients.
AHAs and other active ingredients are generally more effective at higher concentrations. That said, you might be tempted to use AHAs on a daily basis right off the bat.
This is one of the most common missteps in choosing AHAs. Acids can be highly irritating if applied to the skin without preparation.
Our skin needs to be introduced to the acids slowly, starting from the lowest concentration possible and working all the way up.
With this, you can avoid issues like irritation, redness, and other complications. As mentioned, this can be done through low-concentration products like AHA toners.
- Incorporating it successfully into your skincare regime.
Knowing how to layer your skincare is crucial in getting the product to reach your skin and be fully effective.
One basic rule of thumb is: that products should be applied from the lightest to thickest consistency. So your serum should be layered sometime after cleansing and before your moisturizer.
Another important point to remember is to wait until your serum is fully absorbed before layering on the next product. This should be around 5-15 minutes.
- Be wary of skin irritation vs. allergic reaction.
Whenever you’re introducing a new product to your skin, especially if it has potentially irritating actives like acids, it’s important to check if you’re allergic to any of the ingredients. This is done by doing a patch test.
This way, you’ll be able to differentiate between an allergic reaction and skin irritation. If it reacts in your patch test outside your face, you’re likely allergic. It’s best to take note and avoid the product overall.
If it reacts to your face, it’s probably irritation. This isn’t a lost cause by far. One of the most common misconceptions people have is just because a product is irritating, it’s not working or you won’t be able to use the product anymore.
You actually just need to start with a lower concentration of acids and work your way up.
- Observe precautions when starting to use acids if you have sensitized skin.
If you have aggressively overused a product and currently have over-sensitized skin, it may be best for you to transition away from these harsh products to allow your skin to recover.
Reset your skin’s natural barrier by going back to basics–a gentle cleanser, moisturizer, and sunscreen.
Try going by this for a few weeks and slowly incorporate your products to better acclimatize your skin and avoid irritations.
Generally, two weeks is sufficient for your skin to rebuild its compromised skin barrier.
Below is a general skincare routine you can follow, applicable for all skin types. If you have several products that you layer, you can insert them between your serums and moisturizers.

For the best results, choose a product that is suited for your skin type and skin concerns.
Sunday Riley – Good Genes
Best for: All skin types especially dry skin, dehydrated skin, mature skin; Winter seasons, Fine lines & wrinkles, dull & uneven skin tone, Sagging skin
Sunday Riley’s lines are cult favorites and holy grail products to many skincare enthusiasts.
Their products are very potent, just below prescription level concentrations, but formulated so it’s gentle and non-irritating.
This serum is known for its immediate and dramatic effect on the skin. It’s been credited with smoothing, brightening, and plumping effect the day after using it as a night cream.
Key Active Ingredients:
- Pharmaceutical-grade Lactic Acid – superior is its ability to signal the skin cells to increase hyaluronic acid production, which results in a dramatic increase in dermal moisturization; ideal for sensitive skin as it’s one of the gentlest and safest acids to use; helps maintain the skin’s natural pH level; works well with skins of color and those prone to dryness, discoloration, and post-inflammatory hyperpigmentation
- Licorice – an antioxidant that helps get rid of free radicals–one of the leading causes of skin aging, helps with inflammation and skin irritations, fades dark spots and post-inflammatory hyperpigmentation (acne spots)
- Lemongrass – increases circulation for a healthier complexion
Expected results from long-term use include reduction of dark spots, fine lines, and wrinkles, restoration of sun-damaged skin, increased skin firmness, and an evened-out skin tone.

Cons: Highly coveted, so it’s hard to come across it, especially during winter. It’s also one of the most expensive serums out there and will be one of your skincare investment pieces. The concentration can be too potent for very sensitive skin, so best to do a patch test before going all out.

Jan Marini Bioclear Face Lotion
(Glycolic Acid, Azelaic Acid, Salicylic Acid)
Best for: Normal to Combination skin, Oily skin
The Bioclear Face Lotion is Step 3 of Jan Marini’s “The Skin Care Management System™”, voted as the best skincare system for 11 consecutive years by NewBeauty Magazine’s Annual Beauty Choice Award.
This alpha hydroxy acid face serum is a potent combination of 3 clinically proven acids: glycolic, salicylic, and azelaic acid.
This blend of AHAs comes as a multi-functional resurfacing serum that reduces the appearance of acne scarring, large pores, redness, uneven texture, wrinkles, and fine lines.
Results will deliver you dramatically clearer, smoother, and more radiant skin.
These particular acids are also great in combating acne. Just be careful that your skin isn’t sensitized when you use this. It’s quite strong and can further irritate sensitive skin. Repair your skin barrier first before trying any new acids.
Shake well before using. Apply a few drops to your face in the morning and evening.
Key Active Ingredients:
- Glycolic Acid — one of the most widely used AHAs that helps exfoliate and renew the skin
- Azelaic Acid — has anti-inflammatory and anti-microbial properties that are effective against acne and rosacea
- Salicylic Acid — a beta-hydroxy acid that cuts through oil to clear out pores and dissolves dead skin that can clog pores
Cons: Can be too strong for sensitive skin. To build tolerance, start twice a week and gradually increase use to twice a day (morning and evening). You may experience some minor flaking as your skin renews itself at the beginning of using this product. You can follow this up with a hydrating moisturizer.
Best for: Normal to Combination skin, Oily skin

La Roche-Posay Effaclar Pore-Refining Anti-Aging Facial Serum
(Glycolic Acid, Lipo-hydroxy Acid)
Best for: Oily skin, Acne-prone skin with large pores, Sensitive skin, Rough & Dull skin
A long-standing product that remained on the brand’s best-selling list throughout the years.
This pore-minimizing serum targets large and open pores and works to soften and visibly reduce their appearance.
The consistency of the serum is light and especially fast-absorbing, making it ideal for oily skin.
The formulation is also non-comedogenic; reducing any possible incidences of blackheads, whiteheads, and acne formation.
Fragrance-free and paraben-free. This doesn’t contain excessive additives that can potentially cause irritations (which is what La Roche is known for).
Key Active Ingredients:
- Glycolic Acid – this type of AHA has one of the smallest compounds of all the acids, which makes it very easy to penetrate the skin and help deliver beneficial properties; accelerates collagen production and improves skin firmness; helps fade spots and dark patches as it works to continuously exfoliate the skin
- Lipo-hydroxy acid (LHA) – is a relatively new type of hydroxy acid that, aside from its usual hydroxy acid properties of skin exfoliation and renewal, has anti-bacterial and anti-inflammatory properties as well; it also provides micro-exfoliation and latches on to oil more effectively than glycolic acid (which is water-soluble and more effective on dead skin cells); LHA can also operate at a much lower pH than normal acids so there is a lower potential for irritation
Cons: While targeted for oily and acne-prone skin, this product should be treated as a booster to your skincare lineup instead of an acne solution. If you have cystic acne or blackheads, this can only minimally help you actively fight those if used on its own.
This serum would work best in tandem with your medication as it will boost efficacy by helping your other products penetrate the skin more easily.
Best for: Oily skin, acne-prone skin with large pores, sensitive skin, rough and dull skin

- Kojic Acid – has skin-lightening properties to reduce visible skin discolorations
- Tranexamic Acid (TXA) – a brightening agent that interferes with melanin production to reduce hyperpigmentation and improve skin complexion; makes this the perfect aha serum for acne marks

- Tri-peptide matrixyl – rebuilds collagen and hyaluronic acid, which helps repair damaged skin and restore its firmness
- Polysilicone-15 – Provides sunscreen protection against UVB rays
The consistency is smooth and silky, ensuring quick absorption. Perfect for oily and acne-prone skin.
Their bottle is unique as well–an airless pump that prevents oxidation of your vitamins, ensuring full potency until the last drop. Great for travel.
They also have a 100% money-back guarantee, which is always reassuring as a consumer as it shows their confidence is results-based rather than just marketing.
Cons: Not fragrance-free as expected, which is a little disappointing considering it’s a hypoallergenic product. It has a light citrus scent.
Also a flip side for products with such a variety of blended active ingredients, you’re likely going to get a small portion of each at a time. This is unlike serums like Sunday Riley’s Good Genes above or the La Roche-Posey Effaclar below, where the limited ingredient list allows it to deliver its benefits at a very potent rate.
Best for: All skin types especially sun-damaged skin, oily and acne-prone skin, mature skin, and dry skin

What are AHA Serums?
When applied to the skin, AHA serums can stimulate the exfoliation of old, roughened skin to promote cell renewal. Basically, this method tells your skin to speed up its regeneration process.
AHAs or Alpha hydroxy acids are one of the most effective active ingredients found in skincare today. AHAs are used in the treatment of acne, scarring, pigmentation, dryness, and wrinkles.
In fact, it is one of the most popular ingredients used to reverse the leading cause of skin aging today: photodamage (sun damage).
When we were younger, this isn’t really something we had to worry about because our skin is working at its optimal efficiency. However, as we grow older and expose our skin to damage, this regeneration process gradually slows down.
This results in a slew of issues like clogged pores, dull skin, wrinkles, dryness, and uneven skin tone among others.
AHA serums can invigorate and revitalize your skin so it’s able to regenerate quickly and correct the damage that your skin has incurred throughout the years.
What are the Benefits of AHA Serums?
Clinical trials have shown that hydroxy acids bring significant improvements in skin hydration, elasticity, tone, texture, and smoothing wrinkles.
Alpha hydroxy acids were actually initially used in dermatology to treat other serious skin conditions like hyperkeratosis.
However, when they found that AHAs also promote softer and smoother skin, and lighten blemishes, faded wrinkles, and age spots; they soon began to have a major role in cosmetic skincare.
Further studies have also shown improvements in the skin’s barrier function and restored firmness.
In one scientific study, a twice-daily application of 4% L-lactic acid formulations (pH 3.7-4.0) lead to significant improvement in protective barrier function and reduced sensitivity to common skincare irritants like sodium laureth sulphate (SLS) after 4 weeks.
Major benefits of AHA serums include:
- helping diminish the appearance of fine lines and hyperpigmentation (acne spots)
- rejuvenates dull, lifeless skin
- smoothens out skin texture
- evens out skin tone
- combat mild acne, blackheads, and whiteheads
- restore hydration and maintain proper moisture levels in the skin
- improve skin barrier function and skin firmness
- improve the effectiveness of other skincare products
- stimulate the exfoliation of old, roughened skin to promote cell renewal. This process speeds up the skin regeneration process.
The higher the concentration of the acid and the lower the pH (the measure of acidity) of the product, the more effective it will be.
However, the strength of the formulation is also related to its ability to cause skin sensitivity.
One way to minimize this is by raising your skin’s tolerance to acids and lowering your skin’s pH levels through AHA toners.
Once the skin is conditioned enough, you can deliver higher concentrations of acids in the form of serums or chemical peels for more dramatic results.
How to Incorporate the Best AHA Serums in Your Skincare Routine
One quick rule in layering products: apply them on from the thinnest to the thickest consistency. Make sure to also give them a few minutes to absorb. This technique will make sure that all your products are in full effect and work in synergy.
