Blemishes

Blemishes form when excess sebum, dead skin cells, and bacteria combine to clog pores, creating the congestion that leads to visible breakouts. Contributing factors include hormonal fluctuations, a disrupted skin microbiome, an impaired skin barrier, and the buildup of dead skin cells that accumulates when cell turnover slows. The most effective approach addresses both the visible blemish and the underlying conditions that allow congestion to keep forming.

Willow Bark, naturally forming Salicylic Acid, is one of the most effective botanical ingredients for blemish-prone skin. It contains naturally occurring salicylates that help dissolve the buildup of dead skin cells and excess oil inside pores, visibly reducing congestion and the appearance of blackheads without the harshness of synthetic acids. Enzymes are another effective ingredient for blemish-prone skin because they help loosen and break down dead surface skin cells that can contribute to clogged pores and dullness. Unlike harsher physical scrubs, enzyme exfoliation helps smooth and refine skin texture with less irritation, making it especially beneficial for sensitive or breakout-prone skin. Paired with Probiotics, which rebalance the skin microbiome to reduce the conditions that allow blemishes to reoccur, Exponent's Clear Comeback addresses both surface congestion and the deeper microbiome disruption that keeps breakout-prone skin in a cycle of flare-ups.

Yes. Retinol accelerates cell turnover, which helps prevent the buildup of dead skin cells that contributes to clogged pores and congestion. With consistent use, it visibly refines skin texture, reduces the appearance of pores, and helps fade the look of post-blemish marks and uneven tone. In Exponent’s clinical testing, 97% of subjects showed a measurable decrease in global facial fine lines and wrinkles after 1 week, with 100% showing improvement at 4 weeks. Subjects also demonstrated visible improvements in skin smoothing and texture over time. If you are new to retinol or have sensitive blemish-prone skin, Clear Comeback is a gentler entry point before layering in Time Rewind.

Willow Bark is the botanical source from which Salicylic Acid was originally derived. It contains natural salicylates that exfoliate inside pores and calm inflammation, delivering similar clarifying benefits to synthetic salicylic acid but with a gentler delivery profile that is better tolerated by sensitive and reactive skin. For blemish-prone skin that struggles with conventional acid formulas, Willow Bark offers an effective alternative without the irritation risk.

Breakout-prone skin is often associated with a disrupted skin microbiome — an imbalance of bacteria on the skin's surface that compromises the barrier and creates conditions where blemishes form more easily. Probiotics help rebalance that ratio of beneficial to harmful bacteria, strengthening the skin's natural defenses and reducing the frequency and severity of flare-ups over time. In Exponent clinical testing, 100% of Clear Comeback subjects showed a measurable decrease in blemishes after just 1 week.

Enzymes help blemish-prone skin by gently dissolving the buildup of dead skin cells that can clog pores and contribute to blackheads, congestion, and uneven texture. Unlike harsh scrubs, enzyme exfoliation helps smooth and clarify skin with less irritation, making it ideal for sensitive or breakout-prone skin types. Exponent’s Clear Comeback Probiotic Enzyme Serum combines exfoliating enzymes with Willow Bark and Probiotics to help visibly refine pores, reduce congestion, and support the skin barrier. In Exponent’s clinical testing, 100% of subjects showed a measurable decrease in blackheads after just 1 week of use.

Yes. Clear Comeback is clinically tested on sensitive skin with no irritation reported. Willow Bark's natural salicylates are gentler than synthetic acids, and the probiotic and enzyme formula works with your skin's biology rather than against it. If you have been reactive to conventional blemish treatments in the past, Clear Comeback is formulated specifically as an effective alternative. Note that if you are also using Time Rewind Retinol, alternate nights rather than using both simultaneously or use Clear Comeback in the daytime, Time Rewind Retinol in the evening, as the Willow Bark in Clear Comeback may increase sensitivity when layered directly with retinol.
