Brief Answer:
I suggest an exfoliating cream/ moisturizer containing AHA's

Detailed Answer:
Hello. Thank you for writing to us at healthcaremagic

I have gone through your query and I have understood your concern.

As such there are no oral supplements that are recommended for enhancing skin provided you are taking a healthy nutritious diet.
External supplements like vitamins or minerals are not required for skin and would do nothing at all, in terms of what you wish for.
In order to enhance your skin you need to take care of your skin from outside.
You may use a cream or moisturizer that contains Alpha Hydroxy Acid's (AHA's) like glycolic acid, lactic acid etc.
AHA's exfoliate superficial dead skin cells and renew it with newer younger cells.
Continued use of AHA's keeps skin in a state of continued renewal. This renewed skin is healthier, lighter and brighter.

You may also opt for a few sessions of chemical peeling, particularly glycolic peel, from nearest approachable dermatologist.
Glycolic peel utilizes a higher concentration of glycolic acid as compared to that present in creams/ moisturizers.
The concentration that is available in peels is 20%, 35% 50% and 70%. Whereas creams contain just 6%, 8% or 10% of glycolic acid.

I also suggest you to use a broad spectrum sunscreen, throughout the day. It should have both UVA as well as UV B coverage.
Regular use of broad spectrum sunscreen would prevent tanning and also delay skin ageing i.e appearance of fine lines and wrinkles.
Some sunscreens are also fortified with vitamin C which has skin lightening as well as antiageing properties.

Besides topical creams and chemical peeling sessions you may also take a few sessions of microdermabrasion to achieve the desired results.

I suggest you to visit a dermatologist in your vicinity for more details and the needful.

Brief Answer:
I suggest you a sunscreen and repair creams containing AHA's

Detailed Answer:
Hi. Good Morning.

You may find a broad spectrum sunscreen OTC.
A sunscreen should be broad spectrum i.e have both UV A as well as UV B coverage.
A sunscreen with minimum spf of 30 and above would be suitable.
L'oreal, Neutrogena, Garnier are all good brands of sunscreens that are available OTC.
Neutrogena dry touch ultrasheer sunscreen which has an spf of 50 is quite good. Use it throughout the day, every 2-3 hours, specially if outdoors.

Or else

You may try Pond's day cream which also contains Spf, therefore there is no need to use a sunscreen separately.

At night you may use Pond's night repair cream.

These are OTC brands and you would find them at a drug store near you.

These OTC brands are commonly promoted as antiageing because they contain AHA's and Retinol which are antiageing as well as good to maintain a healthy, younger looking skin.
