Know Your Ingredients: AHA (Glycolic & Lactic Acid) – The Powerful Active for Your Skin
1. What is AHA (Glycolic & Lactic Acid)?
AHA, or Alpha Hydroxy Acid, is a group of water-soluble acids derived from natural sources like sugarcane (glycolic acid) and milk (lactic acid). These acids are commonly used in skincare formulations to promote exfoliation, improve skin texture, and enhance radiance.
Origin:
-
Glycolic Acid: Derived from sugarcane; smallest AHA molecule, making it highly effective in penetration.
-
Lactic Acid: Found in milk and fermented vegetables; known for its gentle exfoliation and hydrating properties.
Where It’s Found in Skincare:
-
Chemical exfoliants like toners, serums, and peels
-
Anti-aging and brightening treatments
-
Hydrating formulations for smoother skin
2. Why is AHA Used in Skincare?
AHA is primarily used to exfoliate the skin by breaking down the bonds between dead skin cells, revealing fresher and brighter skin underneath. It helps improve skin texture, fade pigmentation, and boost collagen production.
How It Works:
-
Glycolic acid has the smallest molecular size, allowing it to penetrate deeply and accelerate cell turnover.
-
Lactic acid is gentler, making it ideal for sensitive or dry skin while also improving moisture retention.
Science-Backed Facts:
-
Studies show that AHAs stimulate collagen synthesis, reducing the appearance of fine lines and wrinkles.
-
AHAs help reduce hyperpigmentation by promoting even skin tone and increasing skin renewal rates.
3. Benefits of AHA (Glycolic & Lactic Acid)
-
Exfoliates and brightens skin by removing dead cells and improving cell turnover.
-
Reduces fine lines and wrinkles by boosting collagen production.
-
Improves hydration (especially lactic acid) by strengthening the skin’s moisture barrier.
-
Fades hyperpigmentation and acne scars over time.
Who Can Benefit the Most?
-
Oily & Acne-Prone Skin: Helps prevent clogged pores and breakouts.
-
Dry & Sensitive Skin: Lactic acid provides mild exfoliation while keeping skin hydrated.
-
Aging Skin: Regular use helps maintain a youthful, radiant complexion.
Interesting Myth: Some believe AHAs thin the skin, but in reality, they strengthen the dermis over time, making it firmer and more resilient.
4. Possible Side Effects or Precautions
While AHAs are generally safe, overuse or improper application can lead to skin irritation.
Potential Concerns:
-
Skin sensitivity & redness: Due to their exfoliating nature, AHAs can cause irritation if used in high concentrations.
-
Increased sun sensitivity: Always follow up with sunscreen, as AHAs make skin more prone to UV damage.
Safe Usage Tips:
-
Start with lower concentrations (5–10%) and gradually increase.
-
Use at night to minimize sun exposure risks.
-
Combine with hydrating ingredients like hyaluronic acid to reduce irritation.
Who Should Avoid It?
-
Those with highly sensitive or compromised skin conditions (e.g., rosacea, eczema) should consult a dermatologist before use.
