What is the AHA?
The AHA is a group of natural compounds that are found in fruits, dairy products, and even in our bodies. They are the ones that help us exfoliate the skin and eliminate the dead cells that accumulate.
There are several types of AHAs, some with small molecules that have greater penetration depth and faster results but are at risk of affecting sensitive skin, and others with larger molecules that take longer to take effect, but do not cause irritation.
The types of AHA are:
Citric acid: From citrus.
Glycolic Acid: Found in sugar cane.
Lactic acid: Obtained it by fermentation.
Malic acid: Found in apples.
mandelic acid: Derived from bitter almonds.
Tartaric acid: Obtained from grapes.
They are known for their ability to smooth the texture of your skin and give it a more radiant appearance. Helps get rid of dead cells on the top layer, revealing fresher, more luminous skin.
You can find them in serums, lotions, and even cleansers. They are applied directly to the skin, preferably at night, and work while you sleep. But always remember to wear sunscreen during the day!
- Exfoliating: Alpha Hydroxy Acids, which include glycolic, lactic, citric, and malic acids, are known for their exfoliating properties. These acids work to dissolve dead cells on the top layer of the skin, which promotes cell renewal and the removal of dull, lifeless cells on the surface. This gentle exfoliation improves skin texture, leaving it smoother and with a renewed glow.
- Moisturizing: They help improve skin hydration by removing dead cells and allowing moisturizing products to penetrate better. By removing this dull cell barrier, AHAs help skin absorb moisture more efficiently, resulting in smoother, fresher skin.
- Anti-aging: These proteins are essential in maintaining skin firmness and elasticity, which in turn reduces the appearance of wrinkles and fine lines. AHAs also help to brighten and smooth the skin's texture, contributing to a more youthful appearance.
- Lightening: AHAs, especially glycolic and lactic acids, can help reduce hyperpigmentation and dark spots. By exfoliating the superficial layers of the skin, they remove pigmented cells and help reveal a more even and luminous skin. They can also increase the effectiveness of other depigmenting ingredients.
