Catalyst could prove to be the single greatest invention in the history of skin care. Skin Repair Growth Factor (SRGF-7) appears to be active in the following ways; it rejuvenates DNA/RNA by promoting the repair of damaged strands, it reduces scar tissue buildup by improving protein production, it stimulates collagen production and, more importantly, improves the strength and elasticity of the collagen structure, it regulates pigment production so that it functions maximally (for protection) while normalizing melanin output which results in the dramatic improvement of melasma, and solar lentigines (age spots). It corrects DNA damage related to UV exposure thereby healing pre-cancerous lesions and many skin cancers and it repairs many facial capillaries including poikiloderma.
