While both microneedling and lactic acid are popular treatments for improving the skin’s appearance, combining them immediately after a microneedling session isn’t recommended. Let’s break down why and explore the best approach for caring for your skin post-microneedling.
What Is Microneedling?
Microneedling is a minimally invasive procedure that uses tiny, sterilized needles to create controlled micro-injuries in the skin. This stimulates collagen production, which can improve the appearance of acne scars, fine lines, wrinkles, sun damage, and other skin concerns. The process leaves the skin temporarily weakened and sensitive, so it’s important to be mindful of what you apply afterward.
What Is Lactic Acid?
Lactic acid is a type of alpha hydroxy acid (AHA) that works as a chemical exfoliant. It helps remove dead skin cells from the surface, smoothens skin texture, and brightens the complexion. It’s often praised for being one of the milder AHAs, which means it’s less likely to cause irritation compared to stronger acids like glycolic acid.
Can I Use Lactic Acid After Microneedling?
Not right away. Although lactic acid is considered a gentler exfoliant, using it immediately after microneedling can cause irritation and potential damage to the skin. After microneedling, the skin is temporarily more permeable due to the tiny punctures created by the needles. This makes it much more susceptible to any products you apply afterward, including acids like lactic acid.
Applying lactic acid too soon could result in:
Increased irritation: Since the skin is compromised post-microneedling, exfoliating acids like lactic acid can penetrate too deeply and cause inflammation, dryness, or a burning sensation.
Excessive exfoliation: Microneedling already stimulates the skin’s natural cell turnover process, so adding an exfoliant could over-exfoliate the skin, leading to redness, peeling, and potential damage to the skin barrier.
When Can You Use Acids After Microneedling?
After a microneedling session, it’s important to give your skin time to heal before introducing active ingredients like acids. Here’s a general timeline:
Wait 2-3 Days: During the first 48 to 72 hours after microneedling, avoid applying chemical exfoliants (including lactic acid, glycolic acid, or salicylic acid), as well as other potent active ingredients like retinol or vitamin C. Your skin needs time to heal, and applying these products too soon can lead to irritation, redness, and discomfort.
Post-2-3 Days: Once 2-3 days have passed and your skin has begun to heal, you can start introducing acids back into your routine. However, it’s a good idea to apply them after a hydrating serum (like hyaluronic acid) to help lock in moisture and avoid further irritation. Make sure you do a patch test first to check for sensitivity.
What Should You Use Immediately After Microneedling?
Immediately following microneedling, the skin is particularly vulnerable, so focus on hydrating and calming products. The best serum to use after microneedling is hyaluronic acid (HA).
Hyaluronic acid is a humectant, meaning it draws moisture into the skin and helps retain hydration. It can soothe the skin, prevent it from drying out, and support collagen production without causing irritation.
It’s also safe to use immediately after microneedling, as it won’t exfoliate the skin or irritate the freshly treated surface.
What Should You Avoid After Microneedling?
Here’s a list of ingredients to avoid in the first few days post-microneedling:
Retinol and retinoids: These can irritate sensitive skin and further compromise the skin barrier.
Vitamin C: While great for brightening, vitamin C can be too potent for sensitive skin post-microneedling and may cause irritation.
Exfoliating acids (AHAs and BHAs): Like lactic acid, glycolic acid, and salicylic acid, these can be too harsh immediately after microneedling and may cause more irritation than benefit.
Fragrances and essential oils: Avoid products with strong scents or essential oils, as they can trigger redness or sensitivity in freshly needled skin.
Sunscreen is a Must!
After microneedling, your skin is more vulnerable to sun damage, so it’s crucial to apply a broad-spectrum SPF 30 or higher every day, especially if you’re going outdoors. Microneedling and acids like lactic acid can increase photosensitivity, making your skin more prone to UV damage and pigmentation.
Conclusion
While lactic acid is a great exfoliant for improving skin texture and tone, avoid using it immediately after microneedling to prevent irritation and discomfort. Instead, focus on hydration and barrier repair with gentle, soothing ingredients like hyaluronic acid. After a few days, you can safely reintroduce lactic acid or other exfoliating products, but always start slowly and patch test to ensure your skin can tolerate them.
If you’re unsure about what products to use post-microneedling or have any concerns, it’s always a good idea to consult with your skincare professional or dermatologist.
