What are good recommended sunscreens in Singapore for UVA and UVB protection?

Doctor's Answers 1

Hi Elaine!

You should look out for products with SPF 50 and PA +++.

The SPF is a relative measure of sun protection that the sunscreen provides against UVB. For example, if you normally take 20 minutes under direct sunlight to burn, SPF 50 sunblock will multiply that time by 50 for you to 1000 minutes.

The number of +'s behind the PA rating determines the amount of protection against UVA. UVA protection is important to prevent pigmentation and photo-aging of the skin.

There are some additional considerations you may want to make before choosing your ideal sunscreen. For example, whether they are chemical or physical blockers, whether they have antioxidant properties like Vitamin C/E or PLE, or if they are comedogenic or not.

Hope this helps you make your decision!

Regards,

Dr Harvey Ho

Do skincare products, touching face and makeup cause acne? Does isotretinoin increase skin dryness and sun sensitivity?

Wash your face 4 times a day with the prescribed cleanser – This I do not follow for fear of drying out my skin; I only cleanse twice a day. I do not know what is in his prescribed cleanser, so I’m unable to comment on his 4 times a day regime. I personally think that cleansing twice a day is perfectly reasonable, and I do that myself too. I’d rather suspect that the cleanser has some type of a moisturizing/sunblock component in it too – which is why he’s told you to stay off moisturizers and sunblock otherwise completely.

Do I need to use a moisturiser if I have oily skin?

Thank you for your question. I personally believe in applying light moisturisers even for oily skin types, definitely so for combination skin types as well. Skin that is appropriately moisturised actually can normalise oil production. The key is finding an appropriate product to use. Our skin keeps changing with age, so what works now may not work later on. For example, skin moisture decreases with age so good quality moisturisers or serums help a lot with that. I don’t think not using moisturiser now will have long term ill effects on the skin.
