First degree: Sensitive
Symptoms: skin occasionally experiences unpleasant feelings such as stinging, itching, and tightness. Sensitive skin usually has an excessive reaction to aggressions like wind, cold, sun, over-zealous cleansing, which are tolerated by normal skin.
Second degree: Intolerant
Symptoms: skin experiences not only stinging and tightness, but also redness, scaling and burning. Intolerant skin can be even more traumatized with the application of improper skincare products. Sometimes the skin even can’t tolerate any skincare product.
Third degree: Allergic
Symptoms: contact allergy reactions characterized by eczema (redness, burning, blisters or even oozing) or urticaria (swelling, burning).
