The effect of L-cysteine on the skin
1. Whitening and lightening spots
Inhibition of melanin production: By regulating the activity of thiol groups (- SH) in epidermal pigment cells, blocking the melanin synthesis pathway, reducing problems such as pigmentation and dullness.
Diminishing existing pigment deposits: promoting epidermal melanin metabolism, improving uneven skin tone, and making the skin transparent and even.
2. Antioxidant and anti-aging
Neutralizing free radicals: Clearing free radicals generated by oxidative stress, reducing damage to the skin from ultraviolet radiation and environmental pollution, and delaying wrinkles and sagging.
Promote collagen synthesis: maintain skin firmness and elasticity, and improve signs of aging caused by collagen loss.
3. Moisturizing and Barrier Strengthening
Enhance water locking ability: improve skin dryness and roughness by maintaining the moisture balance of the stratum corneum.
Repair barrier function: Strengthen the lipid structure of the epidermis, resist external stimuli (such as pollutants and allergens), and reduce sensitivity and inflammatory reactions.
4. Promote repair and metabolism
Accelerate cell renewal: Participate in protein synthesis, promote epidermal cell regeneration, and repair damaged tissues (such as sunburn, acne scars).
Improve keratin metabolism: Dissolve accumulated keratin protein and alleviate abnormal keratin problems such as chicken skin (perikeratosis).
5. Anti inflammatory and Soothing
Relieve inflammatory response: By regulating immune cell activity, alleviate symptoms of inflammatory skin problems such as dermatitis and eczema
