Brief Answer:
Fairness treatment and
stretch marks treatment
Detailed Answer:
Hi.
Yes, you can use A-Ret 0.1% gel for abdominal stretch marks.
Tretinoin, even if used at higher strengths can be tolerated on abdominal skin unlike face. However, you must use it for an extended period of time (say may 6-9 months or even upto an year) to have noticeable improvement. They definitely improve over time. However it is not possible to completely erase the stretch marks. Creams/gels can improve them only to an extent.
I hope you are using Kojivit gel during the day? It contains 2%
Kojic acid along with sunscreen(octinoxate). Kojic acid itself is a skin lightening agent, therefore on regular use it would improve the complexion OR else you could use a broad spectrum sunscreen throughout the day. Neutrogena dry touch ultrasheer sunscreen is available OTC, marketed by johnsons and johnsons and is also suitable for oily and
acne prone skin. It would prevent sun induced darkening/
tanning.
You can definitely use
Glutathione pills for fairness. Oral glutathione administration results in a lightening of skin color. However, long-term safety has not been established. Mind you: it is not for permanent fairness!! What you can do is, you can use Glutathione pills for 4-8 weeks and once the desired effect has been achieved you can discontinue with glutathione pills and subsequently maintain the improved complexion with kojic acid (Kojivit gel) and sunscreen.
