To keep your complexion look bright and radiant you should research anything with glycolic acids in them they remove dead skin cells and help your complexion to look it's best! Hope this helps!
LOL! You sounded just like me a few years ago. I actually found a moisturizer that I use from head to toe so it's nice to have just one bottle instead of 3 or 4 different kinds sitting around. It's called Beaulee's and it really has changed my skin and made it look and feel healthy. The nicest part is that it's 100% natural so I feel confident applying something healthy to my skin every day. I stumbled upon your question while I was trying to purchase it on this website along with some other items for Christmas gifts. It appears they don't sell it here but they have there own website you can find it by just typing in Beaulees.com. Good luck with it, you'll love it like I do. Enjoy your holidays!
Peter Thomas Roth makes an Anti Aging gel cleanser that has AHA and BHA while Anthony Logistics (though advertised as a men's line) makes an AHA (glycolic) cleanser that also contains aloe to soothe skin. I've used both and love it! They even out a complexion and even clear acne marks and give a brighter complexion.
You may want to look into Philosophy's kits like The Microdelivery Peel (in a two step regimen and peel mask) and Oxygen Peel. All three use differnt methods to give a more radiant complexion, I'm a huge fan of the OP one because it instantly brightens by using a blast of pure oxygen to push out oil, bacteria, and dead skin out pores and clears oxidation damage leaving skin fresher and brighter.
For a quick, temporary fix, use cosmetic products light highlighters and luminzers. Though these come in various forms, liquid, cream, and powder, I love the liquid ones from Benefit (like High and Moon Beam and Girl Meet Pearl), Smashbox's Artificial Light (check their webpage I can't remember if Sephora still carries their liquid version), and Lorac's luminzer. Add a drop to foundation or to your face lotion for an all over glow or slight perk up or do your face make up as is and add a bit to your cheekbones/orbital bone and blend into skin to really pick up on bone structure and give a more designated glow to skin.
I love using the REN AHA Concentrate. It's gentle and effective, and I have acne-prone skin. I also like that the consistency is really light, like a toner, so it goes under my moisturizer seamlessly. Try reading up some reviews on it, and if you feel like it's for you, get a sample of it from Sephora. I hope this helps and good luck!
