Glycolic acid is an AHA that dissolves the bonds holding dull, dead cells to the skin's surface, revealing brighter, smoother skin. With consistent use it also evens tone and stimulates collagen.

Yes — it is one of the best ingredients for dullness. By sweeping away dead-cell buildup, it instantly brightens the complexion and improves radiance over time.

Start with once or twice a week and build up as tolerated. Some gentler formulas can be used more often, but over-exfoliating causes redness and irritation — let your skin guide you.

Yes. By accelerating cell turnover, glycolic acid helps fade hyperpigmentation and even out skin tone gradually, especially when paired with brightening antioxidants and SPF.

They suit different needs — glycolic (an AHA) resurfaces the surface for brightness and texture, while salicylic (a BHA) gets inside pores for blackheads and breakouts. Some routines use both.

Cautiously — both increase turnover and can irritate when combined. Many people alternate nights or use them on separate days, always with moisturizer and daily SPF.

Yes. Beyond smoothing and brightening, consistent glycolic use stimulates collagen, softening the look of fine lines and improving firmness over time.

It can be irritating for very sensitive skin. Start with low concentrations and infrequent use, or choose a gentler AHA like lactic or mandelic acid instead.

Absolutely. AHAs make skin more sensitive to UV, so daily broad-spectrum SPF is essential to protect your skin and your results.

Mild flaking can happen, especially when starting or using higher strengths. If you see significant peeling or redness, reduce frequency and focus on hydration.

AHAs like glycolic are water-soluble and resurface the skin's surface for brightness and texture. BHAs like salicylic are oil-soluble and clear inside pores — better for oily, breakout-prone skin.

Acid formulas are sensitive to age and storage. An authorized retailer like SkinCrew guarantees fresh, authentic, properly stored product that performs as intended.
