**Can Lactic Acid Lead to Skin Purging?**
Have you ever tried a new skincare product only to find your skin breaking out or flaring up with blemishes? Don’t be too quick to assume it’s a bad reaction—it might not be what you think! While it’s possible that certain ingredients in the product, such as a heavy face cream or something you’ve never used before, could be the cause, the breakout might also be due to a natural skin response called *purging*. If you’re not familiar with this term, don’t worry—you’ve come to the right place!
In this article, we’ll focus on skin purging related to AHAs (alpha hydroxy acids), particularly lactic acid, as it’s known to be one of the milder exfoliants in skincare.
### What Exactly Is Skin Purging?
Purging is often confused with a typical breakout, but it’s a different process. Unlike breakouts caused by clogged pores, purging happens when active ingredients, such as exfoliants, speed up the skin’s cell turnover rate. This means the top layer of dead skin cells is sloughed off, which eventually leads to a brighter, smoother complexion. However, during the purging phase, you might experience more blackheads or pimples as your skin works to expel impurities from the deeper layers of your pores. The purging phase usually lasts anywhere from 4 to 6 weeks. During this time, it’s important to stick with the product to allow your skin to build tolerance and fully benefit from the treatment.
### What Does Skin Purging Feel Like?
Purging typically presents as small, red bumps that may feel tender or painful to the touch. You’ll also notice common blemishes such as blackheads or whiteheads emerging. This can be easily mistaken for an acne flare-up, but the key difference is that purging is part of the skin’s natural process of detoxifying. Since these red bumps can look and feel like irritation or an allergic reaction, it’s always a good idea to patch test any new product first. Apply a small amount (about the size of a 10-pence coin) to the inside of your forearm and wait 24 hours to check for any signs of irritation. If no redness or itching occurs, it’s generally safe to use the product on your face.
### How Long Does Purging Last?
Typically, purging begins within 2 weeks of starting a new product, particularly if it contains exfoliating acids like lactic acid or glycolic acid. Our skin naturally renews itself every 28 days, but as we age, this process can slow down, leading to a build-up of dead skin cells, which can cause a dull, uneven complexion. When you start using exfoliating products, you may speed up this renewal process, which could lead to a purging phase that lasts anywhere from 4 to 6 weeks. However, because everyone’s skin is unique, it’s hard to predict exactly how long it will last. If purging continues beyond 6 weeks, it’s advisable to consult with a dermatologist to rule out other issues and make any necessary adjustments to your skincare routine.
### Which Acids Cause Purging?
Several skincare ingredients can trigger purging, including:
– **Retinoids/retinols**
– **AHAs**, such as lactic acid and glycolic acid
– **BHAs**, particularly salicylic acid
These acids are chemical exfoliants that help remove the top layer of dead skin cells and clear out impurities from the pores. After the initial purging phase, you’ll likely notice an improvement in skin clarity, and other products will absorb more effectively.
### Can Lactic Acid Harm Your Skin?
No, lactic acid is one of the gentler AHAs used in skincare. Unlike other acids like glycolic acid or salicylic acid, lactic acid has a larger molecular structure, meaning it works only on the outer layers of the skin. This makes it suitable for most skin types and less likely to cause irritation or penetrate too deeply into the dermis. Additionally, lactic acid is a humectant, meaning it draws moisture from the surrounding environment, helping to keep your skin hydrated and plump, reducing the appearance of fine lines and wrinkles.
### How Long Does Lactic Acid Purging Last?
Similar to other purging phases, you can expect the effects of lactic acid to last between 4 and 6 weeks. Since lactic acid is considered gentle, you might find that the purging phase doesn’t last as long as with other stronger acids. However, if you have sensitive skin or are prone to flare-ups, it’s especially important to do a patch test before using lactic acid on your face. If the purging seems excessive or continues beyond 6 weeks, consult with a dermatologist for advice on adjusting the product usage.
To sum up, purging is a natural part of your skin’s adaptation to exfoliating ingredients like lactic acid. Although the initial phase may seem uncomfortable, it’s an important step toward clearer, brighter skin in the long term. Be patient and stay consistent with your routine, and your skin will thank you for it.

DQH Knowledge drop: In your 20s, your skin cell turnover decreases. (Cell turnover is a key component in keeping your skin youthful.) You know what else slows down? Your collagen production. Starting in your 20s, collagen decreases by about 1 percent per year. Should you want to prevent fine lines and wrinkles, start by eliminating behaviors that contribute to premature aging. “If it’s bad for you, it’s bad for your skin,” says dermatologist Michel Somenek.
“Cigarette smoking reduces blood flow to the skin and causes premature wrinkling and a dull skin texture. Making the repeated pursed motion to inhale can also cause smoker’s lines. Alcohol and recreational drugs are toxins for the skin that damage its cellular structure and DNA,” Somenek tells us. “The faster you eliminate vices while you are young, the better chance your skin and body have to recuperate.” Also, adopting an anti-aging routine in your 20s is key. After all, the best offense is a good defense. We spoke to Somenek and experts Joshua Ross and Audrey Kunin to find out more.
Keep reading for the best anti-aging products for your 20s, according to skincare professionals.
Sunscreen
“We all know that the sun is the number one cause of skin aging and starting the prevention in your 20s is very important,” Ross says. “The majority of your sun damage won’t start to appear until you’re in your 30s, so don’t wait until you see it surface or you’ll be behind the curve. Stay ahead of it with a good-quality zinc-based sunscreen worn daily.”
Farmacy Green Defense Daily Mineral Sunscreen
An invisible sunscreen with SPF 30, plus botanical extracts meant to protect skin with tons of antioxidants. Bonus: It’s clean and fine to use under makeup.
Bareminerals Complexion Rescue™ Tinted Moisturizer Broad Spectrum SPF 30
Although we recommend you use your SPF and moisturizer separately, we also understand moments when you don’t have time or energy for that extra step. For those times, this bareMinerals moisturizer is a great thing to have on hand.
Vitamin C Serum
“A great introduction to anti-aging is to start with a vitamin C serum in your morning skincare routine,” Ross says. “It’s a powerful antioxidant that will neutralize free radicals and brighten the skin.” He adds that it’s a great way to counteract the effects of the sun’s harmful rays, which, as previously mentioned, are among the biggest causes of premature aging.
Drunk Elephant C-Firma™ Vitamin C Day Serum
The Drunk Elephant C-Firma is a lightweight serum that promises to give skin a glow by combining the brightening powers of vitamin C with ferulic acid, l-ascorbic acid, and vitamin E. The included sodium hyaluronate is meant to replace hydration loss, so you shouldn’t have to deal with any irritation.
Sunday Riley C.E.O. Rapid Flash Brightening Serum
This potent serum is jam-packed with vitamin C (15 percent, to be exact), which means it’s a potential superstar at both brightening skin and dousing it in antioxidants.
Peptides
Using peptides on your skin has many benefits, says Somenek. “The skin barrier is what defends the body against pollution, UV rays, bacteria, and toxins. It can be damaged by several everyday factors. Using topical peptides aids in building a stronger barrier,” he says. “Peptides comprise elastic fibers, which are a type of protein. These fibers help to make skin appear taut and firm. Peptides can also help repair damaged skin, relieve inflammation, and even out skin tone. Some peptides can kill acne-causing bacteria that is common in 20-somethings.”
Kunin agrees, saying, “Peptides are an excellent entry point for supporting collagen.” She recommends looking for face and eye treatments that contain these collagen-boosting powerhouses.
Charlotte Tilbury Magic Eye Rescue Cream
This Charlotte Tilbury super-emollient eye cream has a base of coconut oil and shea butter (read: it’s incredibly hydrating). Botanicals plus peptides are meant to help reduce dark circles and boost collagen, respectively.
This creamy moisturizer serves up potent collagen-boosting peptides and pycnogenol, and antioxidant-rich vitamin C. “Instead of sitting on top of the skin, peptides penetrate the outer layer so they go deep. The ‘signals’ they send tell the cells to produce elastin and collagen, which are needed for youthful-looking skin,” explains Somenek.
At-Home Peel Pads
Remember that skin cell turnover fiasco we talked about earlier? One way to help support it is by exfoliating. “Exfoliation is important to help keep skin fresh and luminous,” Kunin says. She recommends using at-home peel pads as an easy and effective way to exfoliate.
“The goal in your 20s is to fight the slowing pace of cell turnover. It is wise to use products that gently exfoliate, yet still remove oil and other impurities. Products that have Alpha Hydroxy Acids (AHA) or Beta Hydroxy Acids (BHA) are a good choice.”
According to Somenek, you should only exfoliate two to three times a week. “People of all ages are guilty of over-exfoliating and that can be too much of a good thing,” he says.
Dermadoctor Kakadu C Intensive Vitamin C Peel Pad
A few swipes of this Derma Doctor powerful peel pad promise to leave your skin glowing and smooth, thanks to the seven (yes, seven) types of chemical exfoliants, including AHA and BHA. It also contains vitamin C via Kakadu plum extract for added brightening and antioxidant protection.
KEY INGREDIENTS Kakadu plum extract is sourced from the Kakadu plum, a fruit grown in northern Australia. It contains vitamin C, which restores the skin’s natural barrier, increases collagen production, and soothes irritation.
Dr. Dennis Gross Skincare Alpha Beta® Universal Daily Peel Pads
These are the gold standard of peel pads, with a cult following and over 900 five-star reviews on Sephora. They’re easy to use and contain a blend of anti-aging exfoliating acids.
Emollient Night Cream
“In your 20s, you need to start upping the hydration in your skincare routine. You may have been cautious of over-moisturizing because of acne in your teens, but as you enter your 20s, your skin transitions and becomes drier,” Ross says. “I recommend an emollient night cream added into your evening skincare regimen.”
“Twenty-somethings need to make sure that they are not using creams that will clog their pores and cause excess oil production,” says Somenek. Opt for non-comedogenic products.
Cerave Skin Renewing Night Cream
One great choice is the CeraVe Skin Renewing Night Cream, which is a non-comedogenic night cream that leaves skin soft and glowy. It combines the moisturizing powers of ceramides and hyaluronic acid.
RoC Retinol Correxion Max Hydration Creme
“The best night cream ingredients contain retinol, benzoyl peroxide, and/or salicylic acid or hyaluronic acid. The goal is to moisturize, yet remove excess oil,” says Somenek. This Roc Retinol Correxion cream fits the bill as it contains both hyaluronic acid and retinol so it promises to moisturize while also being non-comedogenic.
