When it comes to skincare, DIYs are really popular and may attract as feasible and cheaper alternative. However, there are certain products that are frequently used in DIY formulas, but surprisingly, should not be used on the skin as it may affect your skin severely.
Camphor is a crystalline aromatic substance obtained from the wood of a tree or manufactured artificially. Camphor is applied on skin, as it produces a cooling effect, which is considered as equal to skin soothing. However, its repeated usage may lead to irritation and sensitivity of skin as well as to eyes. Also, inhaling camphor may affect mucous membranes, cause nausea, or burning. Severely, if camphor is applied to cuts or injured skin, it may act as toxin inside the body.
Lemon is the most sought-after DIY ingredient for brightening, lightening blemishes, scars and reduces fine line as it contains citric acid (Alpha Hydroxy Acid -AHA) and Vitamin C (ascorbic acid), which is an antioxidant. However, lemon juice has a very low pH level i.e. 2 ( highly acidic ), which may cause irritation, sensitivity. When used on the bare skin, it may lead into photosensitivity on exposure to the sun (sensitivity to the UV rays from sunlight), hyperpigmentation, burns, and skin irritation. It may also damage skin barrier function (outermost layer of the epidermis).
Baking Soda is one of the harshest ingredients to be used on the skin. It is widely used for skin exfoliation. The skin has pH level, which typically ranges from 4.5 to 5.5, which is acidic. A pH of 7 is neutral while any level above 7 is alkaline. The pH level of baking soda is about 9, which can be really damaging to skin and may leave a long-lasting negative effect on the skin.
