How do we maintain healthy skin throughout the year? Listen to this talk from UCLA alumna Dr. Jenny Hu. She will provide an unbiased, academic perspective to skin care for men and women. She will educate you on what to avoid, what to acquire, and show you how healthy living leads to healthy skin and vice versa. With advice you can trust, learn how to properly care for your skin and put your best self forward as you age gracefully.


Some notes of this talk:

  • Daily wear of Sunscreen can reduce skin cancer and aging. Look for broad spectrum UVA, UVB protection SPF over 15 or higher. Best is SPF 30 or higher. But you need to reapply it every 2 hours for best result. 

There are 2 types of sunscreen in the market:

1. Physical sunscreen: physically block both UVB and UVA off skin, look for zinc oxide titanium dioxide sunscreen. They are broad spectrum prevented against UVA, UVB. 

2. Chemical sunscreen: absorb UV rays and chemically converts into heat, do not necessarily block both UVB and UVA. 

Avobenzone - blocks both UVB and UVA

MexorylTM (La Roche-Posay Anthelios) - blocks both UVB and UVA

Helioplex (Neutrogena) - blocks both UVB and UVA

It is recommanded to use physical sunscreen as the better options to prevent skin cancer. 



Main Vitamins to look for in your skin products for healthy skin:

  •  Vitamin A

-Carotenoids (May prevent UV-induced collagen breakdown

-Retinoids increase collagen, increases thickness of epidermis ->Reduces appearance of fine line wrinkles

-Chemopreventive effect in skin cancer 

carotenoid rich food are:

sweet potato, beef liver, spinach, carrots, pumpkin pie, cantaloupe, sweet red peppers, mangos, black-eyed peas, apricots, broccoli 

Topical Retinoids includes: 

Tretinoin - Retin-A, Renova, Avita

Tazarotene - Tazorac, Avage, Fabior  

Over the counter (non prescription): Retinol, Retinaldehyde, Retinyl Ester, Oxoretinoid


  • Vitamin C


Increases stability and production of collagen

Theoretically may protect skin from UV-induced damage

Clinical trials: ascorbic acid serum, ascorbic acid 5%, cream, ascorbic acid 10% scream

Challenge of developing ascorbic acid topical formulation that are stable, so look for air-tight packaging, not a screw top lids, it breaks down when exposed to oxygen and light. If any discoloration or yellowing, which indicates breakdown. 

These have better penetration to the skin:

Ascorbyl glucoside (AA-2G) get through the skin, more stable
Ascorbyl tetra-isopalmitate/tetra-isopalmitoyl ascorbate (VC-IP)
Ascorbyl palmitate (AA-PAL)


-sodium ascorbyl phosphate (SAP)

-magnesium ascorbic phosphate (MAP)

-Ascorbic-2-phosphate-6-palmitate (APPS)

-3-O-ethyl ascorbate (EOC)


Vitamin C-rich food: sweet red peppers, orange juice, orange, grapefruit juice, kiwifruit, sweet green pepper, broccoli,  strawberries, brussels sprouts, grapefruit, tomato juice, cantaloupe, cabbage, cauliflower, potato


  • Vitamin E


Regulates collagen breakdown

Protects skin from UV-induced damage

No scientific data at this time to support topical vitamin E for improving skin wrinkling, discoloration, or texture

If choosing topical Vitamin E product, make sure that has Vitamin C incorporated. 


  • Vitamin B3 (Niacin, Niacinamide)

Increases collagen production, Reduces skin hyperpigmentation

But clinical trials examine topical niacin and niacin amide have only been more recent, though promising

Vitamin B3 rich food: 

dairy products, eggs, enriched breads and cereals, fish, lean meats, legumes, nuts, poultry


  • Vitamin D

Protects against UV-induced skin wrinkling. Not enough scientific evidence at this time to support the use of topical vitamins D in treating skin aging

Vitamin D rich food: 

cod liver oil, swordfish, salmon, tuna fish, orange juice fortified with vitamin D, milk fortified with vitamin D, yogurt fortified with 20% DV for vitamin D


  •  Vitamin K

Reduces vascular manifestations of UV-induced skin aging. Not enough scientific evidence at this time to support the use of topical vitamins K in treating skin aging.

Vitamin K rich food: 

Natto, collards, Turnip greens, Spinach, Kale, Broccoli, Soybeans, Carrot Juice, edamame, pumpkin, pomegranate juice okra



Moisturized skin:


-hypoallergenic (product can still cause allergic reaction but there is less risk)

-Non-comedogenic (does not cause acne for face) 

-apply moisturizer immediately after washing (within a few minutes)

-creams and ointments more effective than lotions in moisturizing skin


ingredients that help soothes dry skin

-lactic acid





-mineral oil


-hyaluronic acid fill between the spaces of the collagen, structure and support of the base part of skin, attracts a lot of water

- Ceramides: play essential role in maintaining barrier function of skin
