  • April 28, 2024

Here we are again, standing at the pharmacy in front of the rows of skincare products, exfoliants and cleansers…but which one to choose for our skin?

Beauties, the choice of acids can be overwhelming, and we can’t always be sure of what works best for oily, dry, normal, or sensitive skin unless we have a guide to it all. So we aksed Dr. Costi for insights on the different acids, their uses, and the right way to incorporate them into your skincare routine.

Let’s have a look shall we?

For Oily or Acne-Prone Skin

Salicylic acid, a beta-hydroxy acid (BHA), is a popular choice for those with oily or acne-prone skin. It penetrates deep into clogged pores, controlling excess oil and reducing the appearance of blackheads, dullness, and rough texture. It’s also useful in treating conditions like psoriasis.

How often should you use it?

If salicylic acid is in your cleanser, daily use is generally safe.

For exfoliants containing salicylic acid, limit usage to three times per week to avoid over-exfoliation and dryness.

For Normal Skin

Glycolic acid and lactic acid are alpha-hydroxy acids (AHAs) suitable for normal skin types. Glycolic acid gently exfoliates, revealing smoother, softer, and healthier-looking skin. It is effective for enlarged pores, wrinkles, dark spots, and acne blemishes. However, people with sensitive skin should use it with caution due to its higher potency.

How often should you use it?

It depends on the concentration and your skin’s sensitivity. Some products are designed for daily use, while others are best used a few times a week. Test your skin’s sensitivity and consult with your dermatologist for personalized advice.

For Dry Skin

Lactic acid is a gentler AHA that promotes natural exfoliation by shedding dead skin cells. It’s a good option for those with dry or sensitive skin because it offers hydrating benefits in addition to exfoliation.

How often should you use it?

Products with lactic acid can often be used daily to maintain smooth, soft skin. However, as with any acid, it’s best to start slowly and assess your skin’s reaction.

For Combination Skin

Mandelic acid, another AHA, is ideal for combination skin. It’s gentle, reducing acne, fine lines, and uneven skin tone without irritating sensitive skin. Due to its slower absorption, it’s less likely to cause irritation compared to other AHAs.

How often should you use it?

Although mandelic acid is gentle enough for daily use, always consult with your dermatologist before starting a new treatment.

For Rosacea

Azelaic acid is commonly used to treat rosacea and acne due to its antimicrobial and anti-inflammatory properties. It promotes skin cell turnover and helps unclog pores, making it a great choice for people with these conditions. It’s also safe for pregnant women, who might avoid certain other skincare ingredients like retinol.

How often should you use it?

For best results, use azelaic acid daily. Inconsistent use may not get you the desired benefits, especially in managing common issues like redness and pigmentation.
