AHA (Alpha Hydroxy Acids): These water-soluble acids work on the surface of the skin, gently dissolving dead skin cells. This can help with:

• Exfoliation: Removes dead skin cells for a smoother, brighter complexion.
• Sun Damage: Reduces hyperpigmentation and evens skin tone.
• Fine Lines & Wrinkles: Stimulates collagen production for a plumper, younger-looking appearance.

BHA (Beta Hydroxy Acids): These oil-soluble acids penetrate deeper into pores, making them ideal for oily and acne-prone skin. Benefits include:

• Exfoliation: Clears clogged pores and reduces breakouts.
• Blackhead Removal: Dissolves blackheads for a clearer complexion.
• Reduced Oil Production: Helps control excess oil, minimizing shine.

PHA (Polyhydroxy Acids): These gentle chemical exfoliants offer similar benefits to AHAs, but with a larger molecule size. This makes them a good choice for those with sensitive skin. Benefits include:

• Exfoliation: Removes dead skin cells without irritation.
• Hydration: Attracts and retains moisture for a plump, healthy appearance.
• Sensitive Skin Friendly: Gentler option for those with easily irritated skin.

Common Uses:

Depending on your skin concerns, here's when to reach for each type of acid:

• AHA: Dull skin, uneven texture, fine lines & wrinkles, sun damage.
• BHA: Oily skin, acne-prone skin, blackheads.
• PHA: Sensitive skin, dry skin, uneven texture.

Best Used With:

• Hyaluronic Acid: Pairs well with all three types of acids to help replenish moisture that can be lost during exfoliation.
• Vitamin C: Boosts the antioxidant power of your routine, especially beneficial when using AHAs.
• Sunscreen: Essential for everyone, but especially important after using AHAs, which can increase sun sensitivity.
