If it pecks or you feel a cold feeling when applying a product, it's a sign that it works!
No, no! Although one may be inclined to think it's a good sign, tingling or pulling skin is a sign that it is irritated. Irritation is never a good thing since it often causes redness, inflammation, dry skin, loss of collagen, etc. So, we remain cautious and attentive to the signals our skin sends us and we limit the use of cosmetics containing irritating ingredients.
