Determination of the age of bottles of Yves Saint Laurent

At the very beginning of the story about the determination of the age of bottles YSL interpreter would like to remind that if you are not an employee auction, cataloguer or a collector, the knowledge of the exact year and month of the release of the vial you do not need. Suffice it to think of at least about an era and at that time there was in the world of perfumery.
For Yves Saint Laurent perfume distinguish 5 periods:
1 - the beginning, Charles of the Ritz, 1963 - 1985 years.
The fashion house Yves Saint Laurent was opened in 1961, and its perfume division in 1963. American cosmetic company Charles of the Ritz acquired 80% YSL parfums and controlled almost the whole of his work. At this time came out Y (1964), Rive Gauche, Pour Homme (1971).
In the initial period (up to 1985) wrote on the packaging Made in France-Yves Saint Laurent Parfums and prohibit the sale is not authorized dealers.

YSL 1963 - 1985 on the example of the author, and the photo below the bottom of my bottle of Opium, which is released sometime between 1977 - 1985 years.

2 - American period, the owner of the Yves Saint Laurent Parfums Corp., 1986 to 1992.
Yves Saint Laurent scraped up $ 500 million and bought their perfume department at Charles of the Ritz. On the package at this time wrote Yves Saint Laurent PARFUMS CORP. From 1986 to 1988 without a bar code, in 1989-1992, with a bar code, in 1992 - 1993 with a green dot. At this time, the economic crisis and the first repression IFRA, but until 1993 the spirits were still decent.

3 - The French period. Owner SANOFI, from 1993 to 1999. In 1992, affected by the crisis YSL perfume division was put up for sale and it was bought by one of the largest French chemical and pharmaceutical concerns Sanofi. Pharmacists immediately started saving, lower the cost of the formulation. IFRA also on alert.

YSL Sanofi from 1993 to 1999.
4-period Gucci and Tom Ford. 1999 - 2008 years.
In 1999, YSL perfume began to dispose of Gucci group and its creative head of Tom Ford. The cases began to write Yves Saint Laurent Parfums. This period of the most serious restrictions on ingredients and reformulirovok.

C 2004/2005 years on the boxes came a long list of potential allergens. On the left box 2003 model year, the right - the same fragrance of 2006.

5 - the period of L'Oreal. It began in 2008 and continues to the present. From the logo disappeared word parfums.

YSL L’Oreal 2008 - 2010

In 2011, the brand name of the castrated. Left kutsee YSL Beauté.
About codes YSL little is known. Deciphering codes amenable only period SANOFI-Gucci-L'Oreal.
If the code consists of 4 - 5 numbers, it is 1992 - 2003 years. The first digit in the code - Year, decade, determined according to the manufacturer's name.
For example:
2XXX = 1992
Since 1993, the first intervention IFRA, between Sanofi 1993-1999 (on the box "SANOFI BEAUTE"):
3XXX = 1993
4XXX = 1994
5XXX = 1995
6XXX = 1996
7XXX = 1997
8XXX = 1998
9XXX = 1999
Period GUCCI 1999-2007, (on the box "Yves Saint Laurent Parfums"):
0XXX = 2000
1XXX = 2001
Again IFRA intervention
2XXX = 2002
3XXX = 2003
Since 2004, the codes 1 digit (year of manufacture) and 3 letters, but a year of transition, so you can meet and 4XXX = 2004 and 4ABC, therefore, be guided by the manufacturer name.
At the same time, there is long list of ingredients on the cartons.
Next:
5ABC = 2005
6ABC = 2006
7ABC = 2007
The severest prohibitions IFRA:
8ABC = 2008
During the transition from YSL GUCCI to L'Oreal in 2008 code could look like this: EA00A or similar.
Between L'Oreal Era s (on the box "Yves Saint Laurent" without the word "Parfums")
9ABC = 2009
0ABC = 2010
And here again comes out of the bushes IFRA, (and the inscription "YSL BEAUTE" appears on the boxes)
1ABC = 2011
and long code
62HXXX = 2011
