What is AHA (Alpha Hydroxy Acid)?

AHA (Alpha Hydroxy Acid) is a group of naturally derived acids widely used in skincare products due to their effectiveness in improving skin appearance and renewal. These acids are sourced from fruits, milk, and sugarcane and are known for their ability to dissolve bonds between dead skin cells, making exfoliation easier and enhancing skin texture.

Types of AHA:

1. Glycolic Acid:

• Derived from sugarcane, it is the most effective AHA due to its small molecules that penetrate deeply into the skin.

• Used to improve skin texture, lighten dark spots, and stimulate collagen production.

2. Lactic Acid:

• Extracted from milk, it has hydrating properties and is suitable for sensitive skin.

• Effective in reducing pigmentation and improving skin elasticity.

3. Citric Acid:

• Found in citrus fruits, it helps brighten the skin and balance its pH level.

4. Malic Acid:

• Derived from apples, it has both exfoliating and moisturizing properties.

5. Tartaric Acid:

• Extracted from grapes, it helps improve the appearance of fine lines and enhances skin radiance.

Benefits of AHA for the Skin:

1. Effective Exfoliation

• AHA removes dead skin cells from the skin’s surface, improving skin texture and making it smoother.

• It unclogs pores and reduces the appearance of blackheads.

2. Collagen Production Stimulation

• AHA enhances collagen production, improving skin elasticity and maintaining a youthful appearance.

• Helps reduce wrinkles and fine lines effectively.

3. Skin Brightening and Tone Evening

• Acids like glycolic and lactic help lighten pigmentation and dark spots caused by sun exposure or aging.

• Regular use results in a brighter and more even skin tone.

4. Moisturizing the Skin

• Lactic acid, in particular, has high moisturizing properties, making it beneficial for dry skin.

• It attracts moisture to the skin’s outer layers, enhancing hydration.

5. Acne Treatment

• AHA cleanses pores of excess oil and dirt, reducing the chances of acne and breakouts.

• It also helps fade acne scars due to its cell renewal properties.

6. Improving Scar Appearance

• Regular use of AHA reduces deep pigmentation and scars, making the skin smoother and more youthful.

How to Use AHA:

1. Patch Test First:

• Before applying AHA to the entire face, test a small amount on a small area of the skin to ensure no irritation or allergic reaction occurs.

2. Start with a Low Concentration:

• Initially, choose a product with a low AHA concentration (5-10%) to avoid skin irritation.

3. Apply at Night:

• It is recommended to use AHA products at night to prevent sun exposure on freshly exfoliated skin.

4. Moisturize After Use:

• After applying AHA, use a moisturizer to keep the skin hydrated and prevent dryness.

5. Use Sunscreen:

• Since AHA increases skin sensitivity to sunlight, applying sunscreen during the day is essential.

Contraindications of AHA Use:

• Not recommended for individuals with open wounds or severe skin inflammation.

• People with sensitive skin should use AHA cautiously and at low concentrations.

• Consult a dermatologist before using AHA during pregnancy or breastfeeding.

Additional Tips:

• Start using AHA 2-3 times a week, then gradually increase frequency based on skin tolerance.

• For optimal results, combine AHA with hyaluronic acid for enhanced hydration or vitamin C for improved skin brightening.
