When it comes to chemical exfoliation, glycolic acid vs lactic acid is one of skincare’s most-asked questions. Both are alpha hydroxy acids (AHAs) that smooth texture, refine tone, and boost radiance but their differences make each one uniquely suited to certain skin types and goals. Adding mandelic acid to the mix offers another gentle, effective option, especially for sensitive or acne-prone skin.
What Are Glycolic, Lactic, and Mandelic Acids?
All three are water-soluble AHAs that dissolve dead skin cells to reveal a brighter, smoother complexion.
-
Glycolic acid is derived from sugarcane and penetrates deeply to resurface skin.
-
Lactic acid comes from milk or fermented plants and exfoliates gently while hydrating.
-
Mandelic acid is derived from bitter almonds and features larger molecules, offering slow, even exfoliation that’s ideal for sensitive, acne-prone, or reactive skin.
Molecular Structure & Skin Penetration
The key differences come down to molecular size:
-
Glycolic acid has the smallest molecules, making it the strongest and most effective for deep resurfacing.
-
Lactic acid has slightly larger molecules, staying near the surface for gentle exfoliation with hydration.
-
Mandelic acid has the largest molecules among the three, which makes it slower-acting and very gentle, minimizing irritation while still promoting cell turnover.
Think of it this way: glycolic dives deep, lactic smooths softly, and mandelic works gently over time.
Benefits & Best Uses for Each Acid
Glycolic Acid
-
Refines texture and minimizes fine lines.
-
Targets hyperpigmentation and acne-prone skin.
-
Ideal for oily or combination types seeking visible resurfacing.
Lactic Acid
-
Gently exfoliates while hydrating.
-

Brightens and evens tone gradually, ideal for those new to chemical exfoliants or with sensitive skin.
Why The Laser Serum
If you’re looking for intensive renewal or have congestion, choose glycolic acid.
If your skin leans dry, sensitive, or easily flushed, opt for lactic acid for its soothing, moisture-binding benefits.
For those seeking clarity without irritation, mandelic acid is the perfect middle ground. It is oil-soluble yet mild, helping to target breakouts, uneven tone, and dullness with minimal sensitivity.
The Laser Serum blends glycolic, lactic, and mandelic acids in precise balance to resurface, smooth, and clarify without irritation. Glycolic accelerates renewal, lactic refines while replenishing moisture, and mandelic gently brightens and targets congestion. Together, they deliver professional-level resurfacing that’s powerful yet polished. Consider the Laser Serum as a daily micro-peel that reveals smoother, more radiant skin with no downtime.
Can These Acids Be Used Together?
Yes, but with care. The Laser Serum was formulated to balance all three for optimal results. Each acid works at a different molecular level. Mandelic gently targets surface congestion, Lactic boosts hydration and radiance, and Glycolic refines texture and tone.
Common Questions About AHAs
Is lactic acid safe during pregnancy?
- Generally yes, but consult your doctor for personalized advice.
Does lactic acid fade dark spots?
- Yes, its gentle exfoliation helps lift pigment over time. Clinical results show 90% agree their skin looked less dull, more even toned and noticed a visible difference in luminosity and texture after fifty-six days of using The Laser Serum.
Final Thoughts
Exfoliants are the cornerstone of clarity and radiance. Glycolic acid works deep to refine and resurface, Lactic restores luminosity through gentle hydration, and Mandelic polishes uneven texture while clearing congestion. Together, they create the ultimate renewal that leaves skin visibly smoother, brighter, and more even. The Laser Serum captures this balance beautifully. Formulated to precisely blend all three acids together to deliver the most professional-grade transformation while keeping your skin and your routine effortless.
