Free radical damage can cause skin to age by destroying collagen and elastin — which help in skin elasticity. Ferulic acid is a potent antioxidant that is a great ingredient for anti-aging to fight against this free radical damage.
Hyperpigmentation can be caused by UV exposure, hormones, or genetic disorders. Impeding melanogensis can help you avoid or decrease hyperpigmentation, the process by which melanin is created and transported to the keratinocytes. The reduction of this will aid in evening out skin tones and encourage skin lightening and brightening. Ferulic acid is an inhibitor for the production of melanin, which makes it a GREAT ingredient for those wanting to brighten and combat pigmentation.
Because Ferulic acid is more gentle than other acids, it can be used in formulations for those with sensitive skin. For those with less sensitive, they can use products that combine Ferulic acid with other acids to target pigmentation and chemically exfoliate. That way, they can get even more benefits from cellular exfoliation and renewal for brightening.
