Apply 2 pumps in the morning and evening before other serums. Make sure to let dry for a minute. (Brush your teeth, get dressed or answer an email.) Applying other serums or moisturizers too soon will raise the pH of your skin, effectively deactivating the acidic benefits of First Light Therapy.
Dry skins will benefit from this serum as well, perfect for fighting pigmentation - although dry skins may need to include a more emollient moisturizer at night over our niacinamide rich First Light Lotion. Oilier skins should consider First Light Lotion as their go to moisturizer.
After initiating a brightening skin program for a month or so you can switch to using First Light Products as your daytime regime. At night you may return to Retinols or AHAs to exfoliate at night. Continue First Light Therapy during the day, followed by C & E Antioxidant Serum.
