The Secret to Radiant Skin: the Lactic Acid 

To harness the full potential of lactic acid, introduce it into your skincare routine 1-2 times a week, during your PM regimen to sidestep sun sensitivity issues. Start with a clean canvas by cleansing, then apply a lactic acid-infused serum or toner. Seal the deal with your favorite moisturizer to lock in the benefits. And don’t forget, daytime calls for SPF to protect your freshly exfoliated skin. 

How much percentage should my lactic acid have?

Lactic acid products come in different concentrations, from 5% to more than 30%. A higher percentage is not always better, though. Jumping right to a high percentage product can irritate your skin.

If you’ve never used lactic acid, start with a very low-strength product—5% to 10% max. This will let you see how your skin reacts and also give your skin some time to get used to the acid.

Stronger versions are used by cosmetologists, facialists, and dermatologists for various facial peels. The reason why the free acid even matters is because that is the percentage of acid that will actually penetrate your skin. If you’re unsure or inexperienced with using acids, start small and work your way up.

While lactic acid is a skincare hero, it’s important to know what to avoid when using it: 

  • Retinol: Both agents can lead to irritation. To enjoy the benefits of both, stagger their application—lactic acid one night, retinol the next. 
  • Other Strong Acids: Stick to one AHA or BHA at a time to prevent over-exfoliation and irritation. 
  • Benzoyl Peroxide: This acne-fighting ingredient can dry out the skin. When used with lactic acid, it may intensify dryness and irritation. 

The Kungul app takes your skincare journey to the next level. Here’s what it suggests: 

  1. Seasonal Considerations: Lactic acid is a year-round superstar, but the Kungul app advises caution during summer. The combination of lactic acid and sun exposure can increase the risk of sensitivity and sunburn. Opt for evening use during hot months. 
  2. Product Scanning: Before incorporating any lactic acid product, scan its barcode using the Kungul app. It provides a 3-color code scoring system (green, orange, red) based on the latest scientific findings. Green scores indicate safety, while orange or red scores may signal potentially harmful ingredients. 
  3. Ingredient Insights: Dive deeper with the Kungul app. It offers detailed information on each ingredient in the product, including potential health risks and alternative options. Knowledge is power, and Kungul empowers you to make informed decisions. 

Remember, skincare is deeply personal. What works wonders for one might not suit another. Always conduct a patch test when introducing new products or combinations to your routine. 

The Takeaway 

Lactic acid is more than just an ingredient; it’s a transformative element in skincare. With its ability to exfoliate, hydrate, and rejuvenate, it’s a must-have in your beauty arsenal. So go ahead, introduce lactic acid into your routine, and bask in the glow of healthy, radiant skin.
