Acids are powerhouse ingredients for achieving a healthy, even complexion. But not all acids work the same way. Drawing from expert insights at VIVE Skin Therapy, here's a breakdown of the most effective ones and their targeted benefits.
Best for: blemishes, dull complexion, oily skin
Salicylic acid excels at tackling oily, impure skin and acne. Skin therapist Vivian Heemskerk, who uses acids daily in her practice at VIVE Skin Therapy, explains: "Research confirms salicylic acid penetrates deep into pores to dissolve excess sebum and slough off dead skin cells, making it ideal for blemish-prone skin." As an exfoliant, it reveals fresher, smoother skin.

Best for: dull complexion, pigmentation spots, dry skin
Glycolic acid, a star among fruit acids (AHAs), promotes cell turnover to unveil healthier skin, minimize impurities, and impart a natural glow. Heemskerk notes: "It's beneficial for all skin types, especially as we age and need help shedding dead cells." Studies also show it binds moisture, fades pigmentation, and protects against sun damage.
Best for: pigmentation spots, UV damage, skin aging
The pure form of vitamin C, ascorbic acid, boosts collagen production, mitigates UV damage, and evens out pigmentation by inhibiting melanin. For best results, opt for water-free formulas, as it destabilizes quickly in contact with water.
Best for: dull complexion, impurities, sensitive skin, dry skin
Milder than glycolic acid, lactic acid gently exfoliates while stimulating hyaluronic acid production deep in the skin for superior hydration. It's a go-to for sensitive skin, eczema, and rosacea, as it combats triggering organisms.
Best for: skin aging, impurities, pigmentation spots
Prescription-strength tretinoin is the gold standard for acne and anti-aging, accelerating collagen and elastin production while fading spots. Heemskerk advises: "Start with gentler options like retinaldehyde or retinol if irritation is a concern, though they require higher concentrations for similar results."
Acids deliver optimal results at effective strengths. Check product labels for percentages or ingredient order—higher placement means greater potency.
