The Case for Exfoliating (and How Often You Should Do It)
2025-05-15 · 7 min read
Exfoliation removes the layer of dead skin cells that accumulates on your face and body, revealing fresher skin beneath and allowing other products to penetrate more effectively. Without regular exfoliation, dead cells build up, trapping oil and bacteria in pores — leading to dullness, acne, and rough texture that no amount of moisturizer can fix.
There are two types: physical and chemical. Physical exfoliation uses a scrub or tool to manually remove dead cells. Chemical exfoliation uses acids — AHAs like glycolic and lactic acid, or BHAs like salicylic acid — to dissolve the bonds holding dead cells to the surface. Chemical exfoliation is generally preferred for the face because it works more evenly and with less risk of micro-tears.
For most guys, chemical exfoliation two to three times per week is the sweet spot. Paula's Choice 2% BHA Liquid Exfoliant is the gold standard — a leave-on salicylic acid treatment that unclogs pores, reduces blackheads, and smooths texture. Apply after cleansing, wait a few minutes, then continue with your regular moisturizer and sunscreen.
If you prefer physical exfoliation, use a gentle scrub with fine, rounded particles — not walnut shell or apricot pit scrubs that create irregular tears in the skin. Dermalogica Daily Microfoliant uses rice-based enzymes and salicylic acid for a dual-action approach that's gentle enough for regular use. Apply with light pressure — you're not sanding a floor.
Body exfoliation matters too. Keratosis pilaris — the bumpy chicken skin texture on the backs of arms and thighs — responds well to body washes or lotions containing glycolic or lactic acid. AmLactin Daily Moisturizing Body Lotion contains 12 percent lactic acid and has clinical evidence supporting its effectiveness against KP. Use it daily and expect visible smoothing within two to three weeks.
Over-exfoliation is as damaging as skipping it entirely. Signs include persistent redness, increased sensitivity, stinging when applying products, and a shiny or waxy skin texture. If you see these symptoms, stop all exfoliation for two weeks and focus on barrier repair with a gentle cleanser and ceramide moisturizer. When you reintroduce exfoliation, start at once per week and build up gradually.
