Coveting The Glass Skin Trend - Feature

Beauty trends and routines keep changing over time, but if we’ve learned one lesson in life, it would be that of customization. Looking at thousands of TikTok and Instagram-worthy skincare challenges, it is clear to see that there are no one-size-fits-all solutions in skincare. If you wish to have flawless skin, there’s a lot of researching and testing required. Luckily, I read about the lactic acid serum and my search ended pretty quickly after the discovery.

Active ingredients are necessary to help your skin shed dead cells and reveal healthier skin. One such ingredient that was hyped by social media is glycolic acid, claiming to be the quickest way to achieve the coveted glass skin texture. While such a strong active ingredient worked for South East-Asian skin types by giving them flawless skin that almost looks like airbrush, it caused quite a controversy among other ethnicities. We found out that glycolic acid serum is a pretty powerful exfoliant that may not be the best choice for those with sensitive skin.  So if you broke out into red rashes or fungal acne, you weren’t the only one. (Yes, we figured it out through personal experience too!)

On my quest to find a skincare routine that not just suits my sensitive skin type, I came across many products but struggled to find an exfoliant that could make the roster.

While using the lactic acid serum of a reputed brand on your skin is a great way to get your glass skin texture, it comes with its own list of dos and don’ts. 

Here, we’re going to talk about everything you need to know. 

What Is Lactic Acid Serum? 

If you’re a fan of DIY beauty, you may have tried several homemade masks to improve your skin texture.  If you may have noticed, home remedies for a glowing complexion and hydration often include yogurt. As effective and delicious as it is, we don’t usually think about the science when our grandmothers vouch for a certain recipe!

What Is Lactic Acid Serum? 

However, this also makes it an excellent time to impart some information on the science behind using yogurt or curd on the skin, especially for sensitive skin types. Yogurt is rich in a particular bacteria called lactobacillus, which is extremely healthy for us. When eaten, it improves gut health, reduces body heat, and reduces inflammation. However, the secret sauce lies in what our friendly bacteria produce- lactic acid. 

What Exactly Is Lactic Acid?

Known to be one of the gentlest active agents, when concentrated in a serum, it can work miracles for those wishing to get rid of pigmentation and facial scars quickly. As a member of the Alpha Hydroxy Acids or AHAs, lactic acid is a skin exfoliator that can help improve cell turnover by helping loosen the protein bonds that hold them together. While fermentation of dairy products is the natural derivative of lactic acid, it is synthetically manufactured for serums in a more concentrated version.

How Lactic Acid Serum Is Different From Other Acids Used In Skincare?

As compared to other acids, lactic acids are made up of larger molecules that make them gentler on the skin. While glycolic acid may be excellent for those with a thick epidermis (attributed to ethnicity and DNA), lactic acid is perfect for those with a thinner epidermis that can easily burn with the lowest concentration of glycolic acid serum. While stronger AHAs with smaller molecules can penetrate deeper layers of the epidermis, lactic acid does not, providing a lighter degree of exfoliation. 

This may sound like a sign of ineffectiveness but is actually great news. Not all skin types are the same, especially facial skin. While some ethnicities have much thicker layers of facial skin, others are perhaps only a few layers deep. Not only does this make them prone to tanning and hyperpigmentation, but also can also leave scars that take ages to fade. If such a sensitive skin type used glycolic acid on the face, their first reaction would probably lead to cellular burns or hyperpigmentation, however there are best suitable facewashes for sensitive skin in the market.

Benefits Of Using The Lactic Acid Face Serum In Your Routine

The benefits of lactic acid serum reach far beyond just healing acne. When used consistently, you will experience reduced wrinkles and other signs of aging. If anyone does, this active ingredient understands the meaning of “everlasting youth comes with patience.”

Available in multiple strengths, lactic acid serum can help you reduce fine lines, acne scars, and pigmentation marks. Not only can it help you shed old cells that may be clogged with sebum, bacteria, and excessive oils, but it also does so without the trademark drying effect. Your skin would gradually start to show improvement in texture without compromising the moisture barrier.

Lactic acid, a gentle AHA, tends to provide an extra layer of hydration, which is why you’d notice your skin becoming supple and plump after regular use!

For those experiencing psoriasis, we come bearing great news. Lactic acid serum can work miracles on your skin when it comes to healing scars. 

Before you buy your first bottle of serum, hold on a second. Do you know which skin type lactic acid face serums work best?

What Skin Types Can Benefit From Lactic Acid Face Serum?

The million-dollar question that most self-care enthusiasts forget to ask before trying out fad products is whether or not they would suit their skin or body type. Not only can ignoring such a fundamental question waste money but also put your skin through a traumatic event if things go south and you experience side effects. To help you get this query out of the way, I found experts who could give me accurate information.

What Skin Types Can Benefit From Lactic Acid Face Serum?

As per dermatologists, those who find glycolic acids harsh can opt for lactic acid serums. However, this is too broad a description, so let me clarify it for you. While glycolic acid may not suit you, you don’t have to try it out and suffer a breakout to figure out the answer. 

People with dry and sensitive skin that tends to react harshly to the slightest change in ph levels can give low-concentrated lactic acid serum. Not only will it not cause any itches and burns, but also have lower odds of causing redness and inflammation. 

But wait… are some skin types restricted?

Well, yes. Even though it isn’t as harsh as its other AHA cousins, lactic acid may still be too much for certain skin types.

If you have extremely sensitive and reactive skin, it’s better to steer clear of any AHAs, including this one. Also, people with skin conditions like rosacea(1) and eczema should stay away from chemical exfoliants (since lactic acids are lab created).

Aim to hydrate more than exfoliate, and you will experience softer skin. When in doubt, speak with a trusted dermatologist to determine your skin type and any restrictions rather than finding out for yourself (it didn’t end well for me, and hence a lesson was learned!)

How Lactic Acid Works?

Investing in skincare products can be a daunting experience, but a lot of consumers may not understand how these products work their magic on you. So here’s a brief look into the workings of lactic acid serum for you to arrive at a decision.

As a gentle exfoliant, a serum with lactic acid will help in breaking down the protein bonds in dead skin. This process may cause some tingling on your face but leads to loosening dead cells, thereby making it easy to slough off at a faster rate than the body’s natural pace. As we age, the skin’s regeneration ability and speed start to slow down, especially if you live in a stressful and polluted environment. By using lactic acid face serum, your cell turnover starts to increase, removing several layers of unhealthy cells as a result of acne, hyperpigmentation, or bacteria. 

The acceleration of the skin regeneration process can quickly help to improve your skin texture by thickening the epidermis. With regular use and a supportive skincare routine, you’ll notice firmer, supple, and brighter skin.

While there are several benefits to your skin when you use a serum with lactic acid, experiencing these results may take a little longer. While malic acid, mandelic acid, and glycolic acid work relatively quickly with almost immediate results, lactic acid may take a few weeks to transpire.

A Caveat About AHAs:

One of the main reasons why you may not see glass skin from day 2 of using this product lies in understanding cell turnover. How does it work?
Well, acne that seems to form overnight actually exists under your skin weeks before! It takes about 3-4 weeks for cells to regenerate and exfoliate naturally. This means that the bacteria and sebum stuck in your pores about a month ago are causing pimples and blemishes today. Of course, this is different when we’re speaking about reactive breakouts as a side-effect, allergic reaction, or stressor.

When you start using a serum with lactic acid, it will begin sloughing off the topmost layer of dead cells first. This also means that your skin may go through a purge phase where acne-prone cells may resurface at a quicker rate (within days and weeks rather than months). Once the purge phase is complete, the blemishes will begin to fade and the acne will clear up. Say hello to newfound youth! but Stop using the product if the skin purge lasts more than 4 weeks.

Skincare routines today have several steps that need to be performed in order. These steps work based on the product, its consistency, and how it is absorbed by the skin. When it comes to lactic acid serum, it is essential that you understand how to use the product properly for the best effects. 

Potential Side Effects Of AHA Serum

While it’s great to read about the benefits of a product, consumers also need to be aware of the potential side effects to ensure they don’t have a bad experience. For lactic acid serum, watch out for the following symptoms:

  1. A purge phase where suppressed acne starts to surface due to the increased cell turnover rate. This may make your skin condition a little worse before it gets better. However, this phase does not last more than 2-4 weeks for extremely sensitive skin.
  2. You may experience some mild tingling on your face after application. 
  3. There may be mild dryness due to the exfoliant properties of active ingredients. Try to use a hydrating moisturizer. 
  4. Mild photosensitivity may cause a slight redness.


How to use lactic acid serum

Clean and towel dry your face. Use skin-type-appropriate toners. After skin absorption, take 2-3 drops of your preferred lactic acid serum. Apply the product gently. Serums should never be massaged. The epidermis absorbs them in seconds. Cover your face evenly and let it absorb for two minutes. Moisturize afterward. Lactic acid serums are photosensitive, so this step works best at night. Let it work overnight for supple, firm, and bright skin.

How often should you use a lactic acid serum? 

Use lactic acid face serum at night. Consistency is key! Before applying to the face, first-time users must do a patch test. This serum stops jawline redness and itching. Assimilate new skincare products and active ingredients before using them daily. Use lactic acid serum once a week for two weeks, then twice, etc. Start with the mildest concentrate and increase as your skin adjusts. Check your skin before increasing lactic acid serum frequency and concentration.

How to avoid or minimize the side effects of lactic acid face serum?

Stop using the product if the purge lasts more than 4 weeks. After applying the serum, avoid sunlight because AHAs cause photosensitivity. Avoid such reactions with lactic acid serum. Apply SPF 50+ sunscreen during the day. Build up to using the serum daily. Start with twice-weekly applications and increase product concentration as your skin adjusts.

When should you stop using lactic acid face serum?

If the purge phase does not stop, or if you experience constant breakouts, stop using the product. Other reasons to cease using this or any serum cause a burning sensation, increased sensitivity to light and heat, and redness.


Achieving clear skin is possible when you understand your skin type and use the right products. When compared with stronger AHAs, lactic acid is the gentlest of all ingredients. When used correctly, you can gain several benefits like supple, bright, firm, and clear skin.
