Alpha Hydroxy Acids (AHAs)
Alpha Hydroxy Acids also known as AHAs originate from natural sources such as sugar cane, fruits, and milk. Made up of tiny molecules of water soluble acids, AHAs are widely used in skincare for their exfoliating and skin-renewing properties.
How to use?
Used as a non-abrasive chemical exfoliant suitable for most skin types especially dull skin. Sensitive skin types should always patch test to check skin compatibility. AHAs tend to increase the skin's sensitivity to sun exposure and can increase the risk of sunburn. Limit sun exposure and apply SPF daily. AHAs should not be used with retinol in the same routine. Consider using AHAs in the morning or on alternate nights to retinol.
Key benefits of AHAs include:
Exfoliation: helps to remove dead skin cells from the surface of the skin to promote a smoother and even complexion.
Collagen Production: regular use of AHAs helps to stimulate collagen production contributing to firmer and more elastic skin.
Hyperpigmentation: effective in reducing the appearance of dark spots and hyperpigmentation by promotion even skin tone.
Skin Texture: helps address issues like fine lines, rough texture, and dullness by stimulating cellular renewal.
Types of AHAs:
Glycolic Acid: derived from sugar cane, glycolic acid has the smallest molecular size among AHAs which allows it to penetrate the skin easily. It is widely known for its effectiveness as a non abrasive skin exfoliant, promoting cell turnover, helping to address skin concerns like fine lines, uneven texture and hyperpigmentation.
Lactic Acid: derived from dairy, lactic acid is slightly larger in molecular size compared to glycolic acid making it a slightly gentle option. Lactic Acid helps exfoliate the skin, improve hydration, and brighten skin complexion.
Citric Acid: naturally occurring in citrus fruits, citric acid is used for its exfoliating properties that helps improve skin texture and promotes a more radiant appearance.
Malic Acid: originates from apples and pears, malic acid is used for its exfoliating and skin renewing properties. It contributes to a brighter and smoother complexion and can be beneficial for addressing uneven skin tone.
