6. Composition Stearic acid-17% Sodium bicarbonate-0.5% Potassium bicarbonate-0.5% Glycerin-6% Water-71% Alcohol-4.5% Perfume-0.5%

7. Production The alkali reacts with some of the stearic acid to form a soap which then acts as emulsifier. The polyol (glycerin) prevents loss of moisture. Sodium sterate crystals gives pearly shine . STEP 1-Melt stearic acid STEP 2-Mix water , NaOH and glycerin and heat to the same temperature as stearic acid STEP 3-Mix both the melts together an stir till it becomes creamy.

10. Hydroquinone Used in lightening dark spots and age spots Hence are also called bleaching or lightening agents.

Retinol Helps improve skin texture and tone Removes fine lines and wrinkles It is also one of the best anti ageing mineral.

It is the only antioxidant proven to stimulate collagen synthesis minimizing lines, scars and wrinkles. Hyaluronic acid Hyaluronic acid is often touted for its ability to “reverse” or stop ageing . It is found naturally in young skin and gets destroyed by age. Products with hyaluronic acid are most often used for wrinkle treatment. Copper Peptide Copper peptides promote the synthesis of hyaluronic acid. Studies also show that copper dependent enzymes benefit natural tissue building processes.

12. Side effects Indiscriminate use of skin creams may cause some serious problems like -: Skin harshening and drying Roughness Skin cancer Fairness creams which contain mercury may also cause poisoning.
