MORE ABOUT GLYCOLIC ACID (AHA)
What Is Glycolic Acid and How Does It Work?
Glycolic acid belongs to a group called AHA acids (alpha hydroxy acids) and has the smallest molecular size of all AHAs, allowing it to penetrate the skin easily. It thus works effectively to exfoliate and improve skin texture. When used regularly, glycolic acid helps reduce appearance of fine lines and wrinkles, removes old skin cells, and gives the skin a fresh glow.
Glycolic acid is a naturally derived ingredient extracted from sugarcane, but it can also be synthetically produced. It is hydrophilic (attracts water and is water-soluble) and aids in exfoliating old skin cells, leaving a radiant complexion.
AHAs are commonly used in skincare to reduce the appearance of lines and wrinkles while improving the skin’s visible firmness and evening out skin tone. Their remarkable water-binding properties make them ideal for people with normal to dry skin.
Benefits of Glycolic Acid
There are many advantages to using glycolic acid in your skincare routine. Here are some of the key benefits:
- Exfoliating effect: The acid helps remove old skin cells and smooths the skin.
- Improves appearance of fine lines and wrinkles: Glycolic acid improves visible firmness and can reduce the appearance of fine lines.
- Boosts radiance: Its exfoliating properties give the skin a more radiant tone.
- Suitable for various skin types: It’s effective on dry, mature skin and skin that needs texture improvement.
- Enhances absorption of other ingredients: Glycolic acid helps gently exfoliate the skin’s surface by removing dead skin cells, leaving the skin feeling smoother and allowing other skincare products to work more effectively on the skin's surface.
What Products Contain Glycolic Acid?
There are various types of glycolic acid products, and the right one for you depends on your skin type and needs:
- Cleansers: Gentle facial cleansers with glycolic acid help exfoliate without being too harsh.
- Toners: A glycolic acid toner can enhance clarity and prep the skin for subsequent products.
- Serums: A concentrated glycolic acid serum offers more targeted action, especially for reducing appearance of fine lines.
- Peels and masks: Active peeling products deeply cleanse the skin and remove old cells.
- Moisturizers: Creams with glycolic acid can provide hydration and mild exfoliation over time.
How to Use Glycolic Acid
When incorporating glycolic acid into your skincare, it’s important to follow some guidelines to avoid irritation and get the best results:
- Start slowly – If you’re new to AHAs, begin with a low concentration and use it once a week.
- Increase gradually – As your skin adjusts, you can use glycolic acid 2–3 times per week depending on your skin type.
- Use sunscreen – Glycolic acid increases one’s sensitivity to sun exposure, so daily SPF is essential.
- Pair with moisturizers – To help maintain skin hydration and comfort, follow with a moisturizing cream.
Can You Use Glycolic Acid Every Day?
AHAs, including glycolic acid, are powerful ingredients and should not be used daily by all skin types. People with sensitive skin may experience appearance of temporar irritation and redness if used too frequently. For most, 2–3 times a week is sufficient, while those with more tolerant skin may use it more often, depending on the product and its formulation. Exfoliating peels with higher concentrations of AHA should only be used once a week.
Who Is Glycolic Acid Suitable For?
Glycolic acid is suitable for many skin types, though some should use it with caution:
- Good for: Dry skin, mature skin, and uneven skin tone.
- May cause sensitivity: Those with easily reactive or delicate skin may benefit from starting with lower concentrations and testing the product on a small area first.
- Important note: If you use other active ingredients like retinol or vitamin C, avoid combining them with AHAs like glycolic acid in the same routine to prevent irritation.
Glycolic Acid in Combination with Other Ingredients
Glycolic acid works well with many skincare ingredients, but some combinations require extra care:
- Hyaluronic acid: An excellent pairing to hydrate the skin and reduce visible dryness.
- Niacinamide: Helps calm the skin and improve skin tone.
- Retinol: Should not be used at the same time as glycolic acid, as both are potent and can increase sensitivity.
Summary
Glycolic acid is a highly effective AHA that offers many benefits, including exfoliation, improved skin texture, and reduced fine lines. Its exfoliating action helps reveal fresher-looking skin, leading to visible improvements in skin texture and radiance with regular use. However, since it can increase skin sensitivity, it’s especially important to use sunscreen and avoid overuse.
If you want to enhance your skin’s radiance and texture, glycolic acid can be a great ingredient to include in your skincare routine. Just be sure to use it properly, choose products suited to your skin type, and adjust based on any sensitivity. With regular and tailored use, you can achieve smoother, more radiant skin!
