Introducing a new generation of intelligent self-tanner: Dr Sebagh Self-Tanning Drops deliver a radiant and healthy-looking, sun-free glow whilst helping to shield skin against the aging effects of High Energy Visible (HEV) light/daylight. This blue/violet light is also emitted by smartphones, tablets and laptops. Dr Sebagh Self-Tanning Drops contain HEV Melanin in a fractionated form, which provides a higher level of protection against HEV light. This breakthrough formula helps to protect skin against the aging effects of oxidative stress whilst delivering a beautiful golden glow. Simply mix with your daily moisturizer or serum. Color develops over a few hours and lasts between 2-3 days. Please note: The formula provides no protection against the damaging effects of UV rays. Dr Sebagh recommends always applying a broad spectrum sunscreen with a high SPF to ensure full protection against UVA/UVB rays.
