What is glycolic acid?
Glycolic acid, a water-soluble alpha hydroxy acid (AHA) derived from sugar cane, stands out as one of the most important AHAs in skin care. This is due to its naturally sourced molecules, also known as “small” molecules, which your skin can absorb effortlessly. Known for its benefits, this natural acid from plants such as sugarcane, pineapple and beet plays a crucial role in improving the health and appearance of your skin.
Exploring the wide range of benefits of glycolic acid, we find that it not only helps to fight aging, but also significantly contributes to hydration, exfoliation, treating hyperpigmentation and sun problems.
The Science Behind Glycolic Acid
Glycolic acid, a special AHA derived from sugarcane, has attracted attention due to its small molecular size, allowing it to penetrate deep into the skin and work effectively.
Glycolic acid. BENEFITS
Exfoliation and skin regeneration: Glycolic acid acts as a powerful exfoliant, dissolving the bonds between dead cells on the skin's surface. This speeds up cell regeneration, revealing fresher, brighter skin. By removing the layer of dead skin cells, glycolic acid helps to smooth skin texture and reduce the appearance of fine lines and wrinkles.Moisture retention: In addition to its exfoliating capabilities, glycolic acid is also a humectant. This means it draws water into skin cells, improving hydration and keeping skin firm and hydrated. This dual action of exfoliation and hydration makes glycolic acid a versatile ingredient in skin care routines.
Collagen production: One of the main anti-aging benefits of glycolic acid is its ability to stimulate collagen production. Collagen is a protein that gives our skin firmness and elasticity. By promoting collagen synthesis, glycolic acid helps firm skin, making it look younger and reducing the appearance of fine lines and wrinkles.
Incorporating glycolic acid into your skin care regimen can lead to improved skin texture, tone, and appearance, making it a valuable choice in both antiaging and wrinkle-correcting routines.
Glycolic acid and the fight against aging
Glycolic acid is renowned for its anti-aging properties, providing a reduction in the appearance of fine lines and wrinkles, as well as improving overall skin texture. Here are the key ways your skin benefits from the properties of glycolic acid:
Collagen and elastin production : Glycolic acid stimulates the production of collagen, a vital protein that maintains skin's elasticity and structure, helping to diminish fine lines and wrinkles. It also improves the quality of elastin, ensuring that the skin remains supple and firm.
Skin hydration and texture: Increases the skin's hyaluronic acid levels, which draws moisture into the skin, keeping it hydrated. Regular use leads to a smoother and healthier skin texture by promoting cell regeneration and removing dead skin cells.
Sun problems and discoloration: Glycolic acid helps reduce the harmful effects of the sun and increases collagen and hyaluronic acid levels in the skin, aiding in the repair and rejuvenation process. It can also reduce discoloration, sun spots and acne marks, contributing to an even skin tone. By incorporating glycolic acid into your skin care routine, you can achieve a more youthful appearance with reduced signs of aging and improved skin health.The benefits of hydration and exfoliation
When exploring the range of benefits of glycolic acid, especially its moisturizing and exfoliating benefits, it's essential to recognize its unique properties and how it can be integrated into your skin care routine:
Exfoliation without irritation: Unlike physical exfoliants that can be harsh on the skin, glycolic acid offers a gentler alternative. It removes the top layer of dead skin cells by dissolving the bonds that bind them together, which minimizes the likelihood of irritation. This chemical peel method is especially beneficial for normal, oily and acne-prone skin types, promoting smoother skin texture and reducing the appearance of enlarged pores.Hydration and improvement of skin texture: Glycolic acid acts as a humectant, drawing moisture into the skin. Not only does this help increase hydration, it also aids in the synthesis of glycosaminoglycans, components that support skin firmness and elasticity. The result is a visible improvement in skin texture and tone, making skin appear brighter, smoother and more radiant.
Use in the care routine and combination with other AHAs
For optimal results, it is recommended to use glycolic acid products once or twice a week to maintain skin health without causing irritation. Additionally, combining glycolic acid with other AHAs, such as lactic acid, can improve its effectiveness in smoothing fine lines and treating dark spots on the surface. It is crucial to apply a moisturizer afterwards to minimize any potential irritation and maximize the benefits.
Treating hyperpigmentation and sun damage
Glycolic acid is a powerful ingredient for fighting hyperpigmentation and sun damage, offering a host of benefits for a more even skin tone and protecting against future UV damage.
Hyperpigmentation treatment: Regular application of glycolic acid can gradually fade hyperpigmentation and melasma, making it an ideal solution for those who want to remove dark spots and achieve a more even complexion. By disrupting the production of melanin, the skin's main pigment, glycolic acid helps reduce the appearance of dark spots, ensuring an even skin tone over time.Repair and protect against UV damage: Glycolic acid not only helps reduce the visible signs of sun damage, but also provides a protective barrier against harmful UVB rays, preventing photo-aging and protecting the skin's collagen from sun damage. Its ability to fade dark spots caused by sun exposure and fade the appearance of scars improves overall skin texture and radiance.
Daily skin care: In addition to treating hyperpigmentation spots, glycolic acid plays a crucial role in overall skin health by increasing hydration through the production of mucopolysaccharides and hyaluronic acid and reducing problems such as blackheads, enlarged pores, and various skin conditions.
Choosing the right glycolic acid product
When choosing the right glycolic acid product for your skin care routine, consider the following to ensure you select a product that suits your specific skin type and needs:
Skin type and concentration
1. Dry, normal, combination to oily, blemish-prone, dull, hyperpigmented, rough and mature skin: Opt for products with a 5-10% concentration for over-the-counter options. Professional treatments can provide higher concentrations for targeted problems.
2. Sensitive skin: Start with products that contain less than 10% glycolic acid. It is crucial to avoid combining acids to prevent irritation.
Task
Glycolic acid is relatively safe during pregnancy, but choose products carefully and avoid combining acids for maximum safety.
Product types and application
Glycolic acid is versatile, available in cleansing gels, toners, serums, peels and moisturizers. Products for home use generally range between 5% and 10% concentration, while professional treatments can reach up to 70%. For sensitive skin, start with a lower concentration (about 5%) and gradually increase if it is well tolerated. Consider the pH level of the product, ideally between 3 and 4, for effectiveness.
Combining ingredients for increased benefits
Glycolic acid can be combined with retinol, vitamin C and niacinamide for additional skin care benefits. However, gradually introduce these ingredients into your routine to avoid irritation.
Safety tips and best practices for use
To make sure you're using glycolic acid safely and effectively, consider these guidelines:
Concentration and use: Start with lower potency formulas (below 10%) and gradually increase frequency to avoid dryness and irritation. Higher concentrations (over 10%) should be used under dermatological supervision to prevent serious skin reactions.
Sunscreen: Always apply a broad-spectrum sunscreen with at least SPF 30 when using glycolic acid, as it increases the skin's sensitivity to UV rays. Integrate products with glycolic acid into your routine in the evening instead of in the morning to minimize the risks of sun exposure.
Combining skin care products: Avoid using glycolic acid with other exfoliating products, especially topical retinoids and products that rapidly exfoliate the skin, to prevent irritation. Monitor your skin's reaction and adjust frequency of use, concentration, and consult a dermatologist for personalized advice, especially if you have specific skin concerns.
Keep in mind that while glycolic acid is generally safe to use on the skin when you follow directions, adverse reactions can often be attributed to other ingredients in the product, not the glycolic acid itself.
