RYS Cosmetiques doing business as 4.5.6 is an independent company founded in France at the heart of the French Cosmetic valley in 2019. After an incubation at the LVMH Research Centre via the Cosmet’up Program, we established our own lab and production unit in the Cosmetic Valley. All our processes of R&D, formulation, production, and filling are performed in our lab. Our journey is guided by melanin skin care and we are continuously researching and developing the most innovative skincare solutions for skin phototypes IV, V, and VI.

Our research has shown that treating hyperpigmentation in melanin-rich skin requires both a gentle, yet multi-tiered approach to ensure that all avenues for producing excess melanin are addressed. First, cleanse to prevent the ill-effects of inflammation then,  gently exfoliate to disperse epidermal melanin granules and increase cells turnover and finally use melanin pathways reversing agents that specifically inhibit an important enzyme known as tyrosinase which is chiefly important for excess melanin production. The 3-step pigmentation set is the perfect approach to effectively treat your hyperpigmentation without bleaching your skin.

Step 1: A dime-sized amount of Green Bae Cleansing Gel applied twice daily will ensure that your  skin feels refreshed, smooth, and radiant.
Step 2: Buff away dead skin cells by using the Come Clean Exfoliating-Mask twice a week into your evening skincare routine. 
Step 3: Apply 3 pumps of the Sevenly Delight Brightening Serum to clean skin twice daily, to see the long-term brightening effects after a minimum of 8 weeks of continual use.

Every skin is different and impacted by different variables like age, hormonal cycles, environment, life style etc. Also the longer you've had the hyperpigmentation, the deeper the melanin gets trapped into the skin layer known as dermis and the longer it will take to clear the skin.  With the 4.5.6 Skin routine, fresh marks will typically clear within 4 to 8 weeks while older ones may take longer. The key to success is gentleness, patience, and focus. Attempting to rush the process with high-percentage acids , harsh or bleaching ingredients will lead to inflammation and the worsening of hyperpigmentation.

We’ll freshly mix your "Core Blend" with the correct combinations, concentrations, and dosages of active ingredients like lilium extract, hydrolyzed tapus flower, balanite roxburghii seed oil, palmaria palmata whitonyl extract, alpha arbutin, vitamin C, vitamin B2 ( piroxidine), niacinamide, green tea glycoproteins, lactobacillus/pumpkin ferment, cucumber extract and many more to create a formula that is as unique as your skin needs.
