Lactic acid, an alpha hydroxy acid (AHA), is naturally found in milk and other fermented foods. It’s been used in skincare for quite some time because it’s a gentle exfoliant that can help to smooth and brighten the skin.
More recently, lactic acid has been gaining popularity in nail care, with many people touting its ability to soften cuticles, strengthen nails, and improve their overall texture and appearance. Who wouldn’t want healthier, more attractive nails?
This article will give you a complete overview of lactic acid for nails, including its potential benefits, how to use it safely, and any risks you should be aware of. Is lactic acid the secret to your best manicure yet?
What is lactic acid and how does it work?
Lactic acid is a type of alpha hydroxy acid, or AHA. If you remember your high school chemistry, you’ll know that means it’s a carboxylic acid with a hydroxyl group.
There are other AHAs, such as glycolic and citric acid. Lactic acid molecules are larger than glycolic acid molecules, so lactic acid is considered gentler on the skin.
How it works on skin and nails
Lactic acid works as an exfoliant. It breaks down the bonds between dead skin cells, or desmosomes, and helps your body shed old skin cells and replace them with new ones.
It also acts as a humectant, which means it attracts moisture to the skin and nails.
Some studies show that it has anti-microbial and anti-inflammatory properties that may improve nail health.
Benefits of lactic acid for nails
Lactic acid isn’t just a skincare ingredient; it can also work wonders for your nails.
Cuticle softening and removal
Dry, hardened cuticles? Lactic acid can soften and loosen them, making it easier to gently push them back or trim them. Proper cuticle care isn’t just about looks. Healthy cuticles protect your nails, promote healthy nail growth, and prevent hangnails and infections, and products like Dr. Hauschka Neem Nail & Cuticle Oil may help.
Nail strengthening and growth
Lactic acid might also contribute to nail strengthening. By promoting healthy cell turnover in the nail matrix (where your nails grow from), it could potentially enhance nutrient absorption. Think of it as fertilizing the soil for stronger, healthier nails.
Don’t forget hydration! Lactic acid is a humectant, meaning it helps your nails retain moisture, preventing them from becoming brittle and prone to breakage.
Improving nail texture and appearance
Want smoother, brighter nails? Lactic acid can gently exfoliate the nail surface, reducing ridges and imperfections. It can also brighten nail color by removing dead skin cells and surface stains, revealing healthier-looking nails underneath; using something like a Dr. Hauschka Neem Nail & Cuticle Pen may also help in this regard.
Addressing nail conditions
While lactic acid can be helpful for managing mild nail conditions like dryness and brittleness, it’s important to remember that severe nail conditions require professional treatment. If you’re dealing with persistent problems like infections or structural damage, see a dermatologist or qualified nail technician.
How to use lactic acid for nails
If you want to try lactic acid to improve the look and feel of your nails, here’s how to do it safely:
Product types and formulations
You can find lactic acid in a few different types of nail products, such as:
- Cuticle removers
- Nail serums
- Hand creams
When you’re shopping for a product, pay attention to the concentration of lactic acid. For home use, it’s best to start with a lower concentration, like 5% to 10%.
Application techniques
Here’s how to apply lactic acid to your cuticles and nails:
- Start by cleaning your nails thoroughly.
- Carefully apply the product to your cuticles and the surface of your nails.
- Let it sit for the amount of time recommended on the product label.
- Gently push back your cuticles.
- Rinse your nails thoroughly.
Start by using lactic acid once or twice a week, and then adjust how often you use it based on how your nails respond.
DIY lactic acid treatments (use caution!)
Some people experiment with creating their own lactic acid treatments using diluted lactic acid from milk or yogurt.
If you’re thinking about trying this, it’s super important to get the dilution right and test the pH of the solution. It’s also a good idea to talk to a professional before you try any DIY treatments, just to be safe.
Precautions, risks, and side effects
Like any skin treatment, lactic acid can cause side effects, especially if it’s not used carefully.
Potential side effects
Using lactic acid on your nails and the skin around them could lead to mild irritation, redness, or dryness. To keep these side effects to a minimum, try these tips:
- Use a product with a lower concentration of lactic acid.
- After you use the product, apply a moisturizer to the skin around your nails.
- Be careful not to over-exfoliate your nails.
When not to use lactic acid
You shouldn’t use lactic acid on your nails if you have any of the following conditions:
- Broken or irritated skin around your nails
- An active nail infection
- Sensitivity to AHAs (alpha-hydroxy acids)
Also, it’s a really good idea to test any new product on a small patch of skin before you use it all over. That way, you can watch for any signs of a bad reaction.
Mixing products
Be extra careful when you’re using lactic acid with other exfoliating products. You should never use it at the same time as another AHA or a BHA (beta-hydroxy acid).
Also, if you take any medications that make your skin more sensitive, talk to your doctor or pharmacist before using lactic acid on your nails.
Frequently Asked Questions
When not to use lactic acid
Avoid using lactic acid on irritated, sunburned, or broken skin. If you have extremely sensitive skin, it’s best to do a patch test first. Also, if you’re using other strong exfoliants, such as retinoids or other AHAs/BHAs, be cautious about combining them with lactic acid to prevent over-exfoliation.
Does CeraVe have lactic acid?
Yes, CeraVe offers several products that contain lactic acid, often in their Renewing SA Cleanser and Smoothing Cream lines. These products are designed to gently exfoliate and hydrate the skin, making them a popular choice for those with rough or bumpy skin.
Is lactic acid good for your hands?
Absolutely! Lactic acid can be beneficial for your hands, especially if you experience dryness or rough texture. Its exfoliating properties help remove dead skin cells, revealing smoother, brighter skin. It also has humectant properties, meaning it helps attract and retain moisture.
Is lactic acid good for fingernails?
While lactic acid isn’t directly applied to the nail to strengthen it, it can improve the skin around your nails (the cuticles). Healthy cuticles contribute to healthier nail growth. By exfoliating and hydrating the skin around the nails, lactic acid can indirectly support nail health.
Can you overuse nail strengthener?
Yes, you can overuse nail strengtheners. Overuse can lead to brittle, rigid nails that are prone to breakage. It’s best to follow the product instructions and give your nails breaks from strengtheners to allow them to maintain their natural flexibility.
Summary
Lactic acid can be a good addition to your nail care routine. It can soften your cuticles, help strengthen your nails, and improve their texture.
But it’s important to use lactic acid safely and responsibly. Always follow the instructions on the product you choose carefully. Don’t over-exfoliate, which can damage your nails and the skin around them, potentially leading to issues such as the free edge of the nail growing down.
If you have persistent nail problems or concerns, the best thing to do is to talk with a dermatologist or nail care professional. They can give you personalized advice on how to best care for your nails.
Overall, lactic acid can be a valuable tool for helping you maintain healthy and beautiful nails, as long as you use it correctly.
