Apply once daily, ideally in the evening. The formula can be diluted with other products to reduce strength until skin develops tolerance. Contact of the product with the skin must be of limited frequency or duration. Start slowly—at first, apply every other day and note the skin’s response, then use up to twice daily as tolerated.
For daytime use, always follow with a broad-spectrum sunscreen rated SPF 30 or greater.
Tip: For sensitive skin, use this product once every 7 days at first. Build up usage slowly, then follow the directions above.
