Tanning is the primary cause of the look of ageing, such as fine lines, wrinkles, sagging and dark spots. Long-term exposure will cause your skin to age more quickly, along with increasing the risk of developing skin cancer.

Tanning is the result of increased melanin production, skin's natural pigment.

Skin is considered combination when some areas are dry or normal and others are oily.

Skincare products containing AHAs (such as glycolic acid) or BHAs (such as salicylic acid) help exfoliate the top layer of dead skin cells to reveal more radiant skin underneath. Skin scrubs work similarly by mechanically removing the top layer of dead skin cells

BHAs (beta hydroxy acids), such as salicylic acid, are an effective treatment for reducing the look of pore size by exfoliating the surface cells of the pore.

You have to be able to identify your type of acne before treating your breakouts. There are two types of acne inflammatory vs. non-inflammatory. Non-inflammatory acne has no significant redness or inflammation—you’ll see whiteheads and blackheads. With inflammatory acne, papules, pustules, nodules and cysts are present. Nodules and cysts are seen in more severe acne. Acne varies depending on the severity: Whiteheads are closed, clogged pores Blackheads are open, clogged pores Papules are small red, tender bumps Pustules (pimples) are papules containing pus Large, firm, painful lumps beneath the surface of the skin are nodules Painful, pus-filled lumps beneath the surface of the skin are cystic lesions Best treatments for different types of acne include: Non-inflammatory acne treatments Mild, non-inflammatory acne can usually be treated at home with products containing salicylic acid, alpha hydroxy acids(AHAs) and retinoids including: Benzoyl Peroxide 5% or Benzaderm 10% with Aloe Glycolic / Salicylic 5-2 & 10-2 Pads Hormonal acne treatments If you have hormonal acne, we might try birth control or a pill like Spironolactone. If your acne is severe, you might want to consult a doctor about Accutane or other acne medication. Severe, inflammatory acne treatments For more severe acne with nodules and cysts, prescription treatments like antibiotics, topical retinoids or isotretinoin are used. Talk to your dermatologist about how to best treat your acne may be your best bet. There is a wide range of prescription topical and oral medications, but they require a consultation with a medical professional. In-office, we can perform a range of treatments that may help, including chemical peels, laser and dermal filler treatments. We also suggest using a product with SPF because acne marks can get darker over time when exposed to sunlight.”

There are key products that you should use to prevent the signs of aging. The key products include cleansers, toners, antioxidants, sunscreens and retinoids. Cleanser removes the dirt and oil off your skin. Toners act as a delivery system for your antioxidants. Antioxidants nourish and restore healthier and more radiant looking skin. Sunscreens protect against further sun damage and provide broad spectrum UVA/UVB protection. Retinoids help to increase cell turnover and support healthy collagen production and brighten areas of pigmentation.

Picking a moisturizer can be extremely confusing. If you walk in the skin care aisle, it will make your head spin.There are so many options. There are face creams, body and facial moisturizers, and lotions or ointments for dry, sensitive, light, or dark skin. Add in anti-aging ingredients and sunscreens and the confusion just grows. Picking a moisturizer is a must, no matter what kind of skin you have: oily, dry or a combination of both. In general if you have dry skin, you'll probably want to lock in moisture with a thick ointment. Creams are thinner and are good for normal skin. Lotions are the lightest (water is their main ingredient) and are a good match for oily skin.

No, this doesn’t actually happen — but there is an exception. “Skin can build up a tolerance to retinol, but not a tolerance against their effectiveness,” Robinson says. In fact, jumping around to different products can do more harm than good, so try to stick with it.

“Generally speaking, yes,” says Robinson. Retinol, or vitamin A, is loved by dermatologists for its ability to speed skin cell turnover and boost collagen production. (A retinoid denotes prescription strength, while retinol is over the counter.) The downside: It can be harsh on skin, causing flaking and dryness. InstaNatural’s Retinol Serum ($18.97; amazon.com) offsets any dryness with hydrating hyaluronic acid. If that’s still too harsh for your skin, try a naturally derived alternative called bakuchiol, which is gentler but has retinol-like properties. A good one: Olehenriksen Goodnight Glow Retin-ALT Sleeping Crème ($55; sephora.com).
