Use a sunscreen, wear protective clothing, and limit sun exposure while using this product and for a week afterwards. Daily use of sunscreen recommended with any glycolic product. Use caution when combining with other exfoliating products as this may increase sensitivity. For external use only. Avoid contact with eyes and mucous membranes. Slight stinging may occur upon application. If irritation develops, discontinue use and consult your skin care specialist.
