In a routine you'll most often find AHAs in toners, essences, serums, and peels. Use them after cleansing and before your richer products, so the actives that follow sink in better.
They suit dry, normal, and combination skin best, since they exfoliate while still supporting hydration. Oily skin can benefit too, though BHA acids, which work deeper inside the pores, are often the better fit.
AHAs help fade uneven tone, hyperpigmentation, fine lines, and rough texture. With regular use your skin feels smoother and looks healthier and more radiant.
They pair well with hydrating ingredients like hyaluronic acid, ceramides, and panthenol, which keep skin balanced and lower the chance of irritation. You can also layer them with niacinamide once your skin is used to it. Avoid stacking them with other strong actives like retinoids, pure vitamin C, and other acids in the same routine, since that can leave skin sensitized and irritated.
Most people use AHAs 2 to 4 times a week, depending on the strength and how well your skin tolerates them. Evenings are best, since they make skin more sensitive to sunlight. During the day sun protection is a must, because skin is more vulnerable to UV after using AHAs.
