Intensive Brightening Treatment is a product from the brand PCA Skin designed to improve the appearance of skin tone and texture. The key ingredients in this product are:

1. Retinol: A form of Vitamin A that is highly effective in reducing the appearance of fine lines and wrinkles, improving skin texture and tone, and promoting skin cell turnover.

2. Hydroquinone: A skin lightening ingredient that helps to reduce the appearance of dark spots and discoloration.

3. Kojic Acid: A skin lightening ingredient that helps to reduce the appearance of dark spots and discoloration.

4. Bisabolol: Helps to soothe and calm the skin, reducing redness and irritation.

To use this product, cleanse your skin and apply a small amount to the face, avoiding the eye area. Use in the evening and follow with a moisturizer. Start with once per week, gradually increasing to every other night, and eventually every night as tolerated.

It is important to use a sunscreen during the day when using this product, as retinol can increase skin sensitivity to UV rays. It is also recommended to patch test the product before using and to discontinue use if any irritation occurs. If you have specific skin concerns, it is best to consult a skincare professional before using any new product.
