Heal existing acne and prevent future flare-ups with the Peter Thomas Roth Therapeutic Sulfur Masque. The clay- and sulfur-based mask absorbs excess oil and delves deep into pores to promote exfoliation, draw out impurities and dry up the acne-causing inflammation. Aloe vera soothes blemishes and hydrates your skin to prevent dry, flaky patches from forming. Added bonus? Excess oil is sloughed away which in turn minimizes the appearance of your pores. Key Ingredients: 10% Sulfur: dries acne flare-ups. Aloe Vera: soothes irritation and calms inflammation. Kaolin: absorbs excess oil to shrink the appearance of pores. Bentonite Clay: draws out impurities.
